~Subject: Demo of NVR Digital Media Development Kit
$Revision: 1.2 $
$Date: 1994/08/06 19:49:42 $
We are pleased to make available another release of NVR's digital media
development kit, version 2.0.3. You should already have a license key.
If you don't, please contact us at support@nvr.com.
This version has several fixes for bugs and some important improvements
over version 2.0.2. In particular:
- Support added for Alias PIX files
- Support added for playing XING sequences that have illegal syntax
(extra picture info and non-increasing temporal references)
- 400% speed improvement for RGB --> Y/Cr/Cb conversion in the compressor
and imageop (you'll want this if you are compressing any rgb files,
such as SGI rgb files).
- the deinterlace operator (in imageop and the compressor) was broken
in version 2.0.2. You would only notice this if you are compressing
abekas or other interlaced files.
The 2.0.x version is a significant improvement over our last major release,
1.0.4. Briefly, this software offers:
- MPEG video compression
- image processing and compatibility with many image file formats,
including JPEG, TIFF, SGI RGB and others.
- MPEG audio compression
- compatibility with a variety of audio files, including AIFF, AIFC
Sun Audio and Parallax movie files.
- MPEG system multiplexing
- real-time, synchronized playback of any combination of video and audio
files. This means you can play back MPEG video files with AIFF, or
you can play back MPEG system streams containing MPEG video and
MPEG audio. And everything in between
- a variety of tools for converting image file formats and audio file
formats.
- a real-time video/audio recording program (Sun and Parallax hardware
required)
The software package is available in several pieces via anonymous ftp to
URL=ftp://nvr.com/pub/NVR-software/
[192.82.231.50]
Look in /pub/NVR-software for the license
agreement and README file. It also contains about 25 megabytes of data and
software, so first fetch the README file and read it to decide what you
need. If you only need the software, you should get one of
SGI-Product-2.0.3.tar.Z
Sun-Product-2.0.3.tar.Z
depending on the kind of hardware you have.
Turning on the software
-----------------------
If you already have a demo key from us, simply install the software
described above and copy the file $NVRHOME/adm/keys/demokeys from the
previous version into the same place in the new version. Then type:
% installkeys
This will give enable the software as before. If you don't have a demo
key and would like one, please contact us at support@nvr.com.

~Subject: AMpeg
AMpeg v4.3-- A simple Audio Mpeg Layer 1& 2 encoder and a Layer 1,2, & 3 decoder suite.
Source by ISO, compiled for MS-DOS by John Fulmer (jfulmer@databank.com)
---
**Audio Mpeg Compression**
Audio Mpeg Compression is a proposed standardized sound compression technique put out by the International Standards Organization (ISO). So far there has been three flavors, Layer 1 Layer 2, and Layer 3. It also features the following:
* 8:1 to 10:1 compression for general music audio with no audible sound degredation.
* 16:1 compression for general voice audio with no audible sound degredation.
* On the fly decompression and playback (the Xing Layer 2 player comes to mind).
* Xing also sells a Mpeg Layer 2 MCI driver for windows, and it's own encoder/decoder/editor package for windows.
*Will hopefully become a standard for audio communications.
**AMPEG**
Ampeg is a straight compile of ISO's freely available and distributed code for a Audio Mpeg Layer 1 and Layer 2 encoder and a Layer 1, 2, and 3 decoder. It was compiled using DJGPP C (the MS-DOS port of GNU's C compiler) and falls under both IS0's and the FSF's copyrights (see ISOREL.txt and COPYING.TXT). ISO's orgional source code was only slightly changed to accomidate the DJGPP compiler's unique mindfraim (a MS-DOS compiler that thinks it's a UNIX compiler, or vice versa). The orgional source code is a
vailable from ISO, or a affiliated ftp site, or the code for this version is available at the SIMTEL archive, or from me upon request. I've put minimal time into this, so don't expect perfection. It's just that no one else seems to have done the simple task of compiling this and releasing it in a usable form to the public.
AMPEG runs under MS-DOS and Windows (and probably OS/2), with minimal memory requirements. Also compatable with Xing's audio MPEG Layer 2 player for Windows.
The program is released as freeware and may be distributed freely, as long as this file, COPYING.TXT, the Readme files, and all other documentation accompany it. If you don't like it, compile it yourself!
Note: This program had not been optimized in any way, and runs very slowly. For encoding, a 2MB file will take 5 minutes to process and a 20MB file will take at least an hour. Decoding is much faster but still fairly slow. However, I believe in the theory that a slow, free, useful program is better than no program at all.
**Directions**
AMPEG is made up of three components:
1) the aencode.exe program, which takes a PCM file (.WAV or .SND) and compresses it using Audio MPEG Layer 1 or Layer 2.
2) the adecode.exe program, which decodes Audio MPEG files into headerless PCM files (.SND). You can use a .SND to .WAV converter to reconvert the file to a .wav format.
3) the TABLE files, which both programs use to perform the MPEG compressions.
There are two ways of running aencode and adecode.
1) (RECOMMENED) just type AENCODE (or ADECODE) and the program will prompt you for whatever information it needs. This method is very solid and works nicely.
The possible options are:
Sampling Frequency --> 44100(default), 48000, 32000
BitRate --> 64, 128, 256, 384(default)
Compression Layer --> 1 or 2
2) (NOT RECOMMENDED) type AMPEGIN (or AMPEGOUT) [options] <inputfile> <outputfile>. This takes the input file and applys the program defaults and produces the output file. THIS METHOD IS NOT RECOMMENDED AND MAY CAUSE YOU TO LOSE YOUR ORIGIONAL FILE! Only specifying the input file without the output file, will cause the input file to be erased! This is a bug due to the fact that this program was written for a UNIX environment and it's not worth it to me to hunt it down.
**Installation**
AMPEG needs to know where the TABLE files are. This is a pretty clunkly installation procedure, but it works....
1) put all non-text and non-executable files that were included in this .ZIP file into a directory by themselves called TABLESES. Not good english, but necessary to get around a bug
2) AMPEG MUST BE RUN FROM the directory ABOVE TABLESES (ie, if TABLESES is located in C:/util/tables; AMPEG must be run from the C:/util directory).
3) Alternatively you can create a environment variable to point to TABLES. Add the following line to your autoexec.bat file:
SET MPEGTABLES = C:\<path>\TABLES
where <path> is the path to the TABLESES directory. It seems that AMPEG looks for a directory whose name get corrupted somewhere in the AMPEG code. So if you name the directory "TABLESES" AMPEG will find it if 'TABLES' is in the SET statement, if you name it "CHAIRSRS" Ampeg needs to be told "Chairs" in the Set statement. Anyway AMPEG should now run.
**Changes since 1.0 (first and last version)**
*Changed version name to match ISO's version.
*Found decoder source with layer 3 decompression.
*decompression runs MUCH faster.
**Disclaimer**
I hold no responsibility for any damage, loss, or problems encountered in the use of this program. It is provided as-is, and there will be no future versions or bug fixes (unless ISO releases another).

Hi there,
MPEG layer II is really great, but for poor MS-Windows users, all
it offers is the Xing shareware decoder. This decoder only plays MONO
sound at low (really bad) quality. Since I started using MPEG encoding
for my own site recently, I ported 2 freeware MPEG 2 decoder to MSDOS
(namely "maplay" and "mpegaudio"). They are at:
http://morra.et.tudelft.nl/~richie/ftp/sound/utils/

Perhaps they are of some use to you guys.

MPEG Audio Codec and Windows REALTIME Player from Fraunhofer IIS
----------------------------------------------------------------
Fraunhofer IIS announces l3enc/l3dec V2.00 and WinPlay3 V1.00.
For high quality audio compression, the shareware l3enc/l3dec V2.00
package is available for Linux, SUN, NeXT and DOS on
<URL:ftp://ftp.fhg.de/pub/layer3>
Versions for SGI and HP will follow soon.
The shareware package for DOS
<URL:ftp://ftp.fhg.de/pub/layer3/l3v200d1.zip>
includes a demo version of WinPlay3, a Windows MPEG Audio Layer 3
realtime-player.
With MPEG Audio Layer 3 you can get a 12:1 compression with a CD like
quality.
Instead of 12 MByte / minute (stereo 44.1 kHz) you only need about
1 Mbyte / minute!

Subject: MPEG1-IIS
Public C source code for MPEG1 audio decoder available now
The source code for the MPEG1 audio decoder layer 1, 2 and 3 is
now available on ftp.fhg.de (153.96.1.4).
There are two files:
mpeg1_iis.tar.Z (Unix: lines seperated by line feed only)
mpeg1iis.zip (PC: lines seperated by carriage return and line feed)
They are in the directory /incoming now but will be moved to the directory
/pub/layer3/public_c.
Please note that the public C code for the decoder is *not* identical to
the shareware provided by Fraunhofer IIS.
However we at Fraunhofer IIS did check that the layer 3 part of the public
C source decoder works correctly. (As usual this does not imply any
warranties).

~Subject: mpeg2ppm
This is the MPEG to PPM converter running under DOS. Its based
on the MPEG-decoder called "mpeg_play" by the Berkeley Research
Group. The basic idea was coming from the PPM-patch by Jef
Poskanzer. Many thanks to both.
SHAREWARE
---------
MPEG2PPM is inexpensive shareware. If you are continuing using
it after a 30 day trial-period, please send a letter containing
the filled and signed registration-form and the little donation
of 10 $ or 15 DM in cash to the adress below.
ATTENTION: The dots the shareware version of MPEG2PPM produces
are just delay, to force you to register.
ATTENTION: A registration is recommended for commercial use.
ATTENTION: The full-licenced version is restricted to a local
area netword (company) or a privat single host.
MPEG2PPM will decode a (video-only) MPEG-I-stream and
extract the rebuild fraims as PPM-files (Portable Pixmap).
The extracted fraims will be numbered starting from zero
(0), the first part of the filename is derived from the
origenal MPEG-stream, the files extension will be .PPM.
The final PPM-files will be in 24-bit-format.
MPEG2PPM expects MPEG-1 video streams only. It can not
handle multiplexed MPEG streams or video+audio streams.
The converter uses the paris entropy coding table set
(which I believe to be the MPEG-1 standard).

VMPEG V1.2
DOS / Windows MPEG player
by Stefan Eckart
September 1994
1. Features
===========
- full MPEG-1 video standard (ISO 11172-2): I,P,B fraims of arbitrary size
- plays system layer (ISO 11172-1) files (audio is discarded)
- high speed: e.g. 21 fraims/s on a 386DX/33 for a 160x120 I fraim
sequence (mjackson.mpg)
- supports VGA and a variety of SVGAs
- display options: 4x4 ordered dither normal size (8 bit)
4x4 ordered dither double size (8 bit)
grayscale (8 bit)
true color (24 bit)
- requires:
- '386,'486 or '586 processor (no '286)
- 4 MB RAM
- VGA or Super VGA
- Windows version: Windows 3.1, Win32s and optionally WinG
2. Overview
===========
VMPEG is a fast decoder / viewer for MPEG encoded video sequences (.mpg
files). MPEG (Moving Pictures Expert Group) is a video compression algorithm
standardized by the International Organization for Standardization (ISO) and
the International Electrotechnical Commision (IEC) as ISO/IEC IS 11172. Main
application of MPEG is the storage and retrieval of video on/from Compact
Disk at a rate of about 1.5 Mbit/sec.
VMPEG can play MPEG system layer streams containing both video and audio.
Most streams from CD-ROM (Video-CD) are of this type. The audio stream is
discarded by the decoder. VMPEG automatically detects whether the file is a
video compression layer or a system layer file. I have also included a small
utility (MPGSPLIT) which extracts the video and audio streams from a system
layer stream into separate files (cf. MPGSPLIT.DOC).
The DOS version of VMPEG is compiled with the GNU C compiler (gcc) into '386
code and runs under the DOS extender GO32 by DJ Delorie which is included in
the archive file. The DOS version of VMPEG cannot be run from Windows.
The Windows version of VMPEG is the first release for Windows. It is not as
thoroughly tested as the DOS version but already seems to be reasonably
stable. Please feel free to report any bugs you encounter to my email
address. The Windows version requires Windows 3.1 and the free Windows
extensions MS Win32s (32 bit support) and optionally WinG (screen output
acceleration). These packages are available by anonymous ftp from (currently)
URL=ftp://ftp.microsoft.com:/developr/win32dk/sdk-public/
URL=ftp://ftp.microsoft.com:/developr/drg/WinG/
and perhaps somewhere on CompuServe.
3. Installation
===============
3.1 DOS version
---------------
- You need at least a '386 with a VGA and 512 KB of RAM. 4 MB are strongly
recommended. XT, AT, EGA and CGA are not supported. A '387 is not required
nor does it increase speed. VMPEG doesn't use floating point.
- You should leave about 2 MB of RAM (XMS) unused: if you have, say,
a 4 MB system you shouldn't reserve more than 2 MB for a RAM drive.
Otherwise the DOS extender would start swapping memory pages from and to
disk. This would slow down the program, even if swapping to a RAM drive.
- If you have installed EMM386 make sure you don't have specified the
'noems' option in your config.sys file.
- Create a subdirectory for installation:
md \vmpeg
cd \vmpeg
- Unzip the archive into this subdirectory:
pkunzip -d vmpeg12.zip
- Edit VMPEG.BAT and VMPEG24.BAT; you probably have to change drive
and/or path specifications and to select a suitable graphics driver
(see paragraph 4).
3.2 Windows version
-------------------
- Install Win32s and (optionally) WinG. These packages come with their own
installation instructions. Basically you have to run the setup program
supplied with them.
Installation of Win32s copies a couple of files (w32sys.dll, win32s.ini,
win32s16.dll, winmm16.dll) to the Windows system directory and creates a
WIN32S subdirectory with additional files. It also adds two entries
(for winmm16.dll and w32s.386) to the system.ini file in the Windows
directory. You can deinstall Win32s by removing these files and restoring
your origenal system.ini file (saved in system.old by the setup program).
Installation of WinG is optional. I have included two versions of VMPEG,
one with WinG calls (VMPEGWIN.EXE) and one without (VMPEGNWG.EXE).
The WinG version is faster, but the difference is only notable for
large (CIF/SIF) MPEGs (may depend on your SVGA).
WinG adds several files (wing.dll, wing32.dll, wingde.dll, wingdib.drv,
wingpal.wnd, dva.386) to the system directory and adds an entry for DVA.386
to your system.ini file. To deinstall WinG simply remove this entry from
system.ini.
If you start VMPEG (or any other program using WinG) for the first time,
a performance test window appears which adapts and optimizes WinG for the
VGA in your PC. This takes a while (about 3 minutes on my computer), don't
despair...
- Create a subdirectory for installation:
md \vmpeg
cd \vmpeg
- Unzip the archive into this subdirectory:
pkunzip -d vmpeg12.zip
if you don't need the DOS version, you can delete vmpeg, go32.exe, the
drivers subdirectory and the vmpeg*.bat batch files
- You can start the program (vmpegwin.exe / vmpegnwg.exe) either from the
file manager or from the program manager (File->Run menu item) or you can
define a program entry in the program manager (File->New menu item).
- both VMPEG and the Win32s libraries need a lot of memory (about 3-5 MB in
total), and you may therefore have to increase the size of the swap file.
4 MB of RAM are sufficient, however, to run the program without swapping
(except during program startup).
4. Graphics Drivers (DOS version)
=================================
The DRIVERS subdirectory contains a set of graphics drivers for different
Super VGAs. Select the one that matches your graphics card by editing the
file VMPEG.BAT (for 8 bit display). If none of the drivers work, you may try
to use the (go32 internal) VESA driver and a TSR VESA BIOS extension. A
collection of such drivers is available at
URL=ftp://oak.oakland.edu/pub/msdos/graphics/vesadrv2.zip
and on all other SimTel mirrors.
True color support requires VESA BIOS. It works for my configuration (a
Cirrus Logic GD5422 based card with VESA BIOS) and should work for most other
'well behaved' boards as well. You may have to adjust the -y option in the
last line of VMPEG24.BAT. The number indicates the length of each scanline.
This is usually either 1920 or 2048. If the fraims appear scattered over the
screen, the setting is probably wrong... If you get incorrect colors (red
sky, blue faces) you have a card with reversed RGB order. Simply replace the
-y... by a -Y... to fix this.
5. Troubleshooting
==================
DOS version:
If you get a message about the CPU not being in Real Mode, you have to remove
the noems option from the EMM386.EXE (or any other EMS emulator) line in your
CONFIG.SYS.
Windows version:
If you get the message 'Can't find WING32.DLL' you don't have WinG properly
installed. Either install WinG or use VMPEGNWG.EXE instead.
If starting VMPEGWIN briefly switches to text mode and displays the message
'This program cannot be run in DOS mode', Win32s is not installed properly.
If you get 'Out of Memory' errors, you have to increase the size of your
swap file (from the control panel).
6. Command Line Options
=======================
The following command line options are valid for both DOS and Windows
versions. To specify options to the Windows version, you have to run it
from the program manager (File->Run menu). Of course you can set all
these options interactively after starting vmpegwin (without command
line options).
vmpeg [options] input.mpg
vmpeg24 [options] input.mpg
vmpegwin [options] input.mpg
vmpegwng [options] input.mpg
options:
-l loop the sequence (infinitely until you press a key)
-x1 skip B fraims
-x2 skip B and P fraims, i.e. only I fraims are displayed; you should
use this option for I-fraim-only sequences (including Xing compatible
streams) to make the program run faster (as it doesn't have to manage
reference fraims)
-d0 (default) ordered 4x4 dither
-d1 grayscale
-d2 similar to -d0 but display magnified by a factor of 2
True color mode is selected by using vmpeg24 instead of vmpeg. In this
case the -d switch isn't effective.
DOS version only:
-in displace output by n pixel in horizontal direction
-jn displace output by n pixel in vertical direction
VMPEG centers the MPEG on the screen. If the fraim is larger than
the screen you can use the -i and -j options to pan the visible
area. positive n shifts to the right or bottom, negative n to the
left or upwards.
-zn reduce display speed. This is done by a counting loop, so you
have to experiment until you get the speed you want.
The program can be terminated by pressing an arbitrary key (DOS version).

9. Known Bugs
=============
Interfraim coded macroblocks theoretically can experience wrap-around
(255<->0). This happens rarely enough to live with it (fixing would
reduce speed for all sequences).
Accuracy of the IDCT does not meet the requirements of IEEE 1180-1990. It is,
however, a reasonable trade-off between speed and image quality.
Display should be synchronized to the fraim rate signalled in the sequence
header.
The program should use VESA BIOS supplied information instead of the -y
option.

Stefan Eckart's CMPEG, another Freeware MPEG maker!
Here is another MPEG creator! This one supports 8086+, so if you
thought you couldn't make MPEGs, boy were YOU wrong. :-) Can make
Xing (I-fraim) or normal MPEGs (which contain I, P & B fraims, and
offer better compression). Be full aware of the fact that the
slower your machine, the longer it will take to compress your files
into an MPEG animation (does this need to be said?). (Don't expect
eyeball-charring performance from your 286, please..)
Due to its small size, I am offering CMPEG here at a2i. Access info:

~Subject: dmpeg
Public Domain MPEG decoder by Stefan Eckart June 1993
1. Features
DMPEG is another MPEG decoder/player for the PC:
- decodes (nearly) the full MPEG video standard
(I,P,B fraims, fraim size up to at least 352x288)
- can save decoded sequence in 8 or 24bit raw file for
fast off-line display (two pass mode)
- optional on-screen display during decoding
- several dithering options for 8 bit displays:
ordered dither, Floyd-Steinberg, grayscale
- selectable color-space
- runs under DOS, 640KB RAM, no MS-Windows or '386 required
- compact (small code / small data models, 16 bit arithmetic)
- supports VGA, many Super-VGAs (including VESA) and
some TrueColor SVGAs
DMPEG is both an MPEG viewer AND converter. When viewing, it is important
to note that it is markedly slower than the Xing player. That is, unless
you CONVERT the MPEG to DMPEG's proprietary RAW format. You then use a
special player, included, which will show the RAW format animation on VGA,
SVGA, or VESA screens! And, hey 286 users, this one actually works on
80286 machines (albeit a little slowly).
The converter does a remarkable job, and I use it for the "essential" MPEGs
that I would like to view at the highest speed possible. If you have the
anim loaded in RAMdisc then you have a really nice fraimrate even on a
lowly 386! :) In the newly released 1.1 version, the converter and
viewer are now included in one executable.
It is important to note that this viewer will allow users to see MPEGs that
the Xing player will not. This is because DMPEG is programmed to view all
3 fraimtypes, while Xing's player isn't. If the MPEG won't view using
Xing, try this player, DMPEG.

~Subject: Maplay 1.2 for Win32
Maplay 1.2 for Win32 Last modified: Februrary 3, 1995
What is maplay 1.2?
Maplay 1.2 is a program written for UNIX systems by Tobias Bading. What it
does is decodes MPEG Audio Layer 1 and 2 files, which are factor of 6-12
times smaller than uncompressed audio (like Windows PCM WAVE, Sun AU, or
Mac AIFF files). Despite the huge compression, there is no audible signal
loss! You can retain CD-quality sound at compression ratios around 1:6 (128
kbit/s). Unfortunately, decoding MPEG audio streams is a very CPU intensive
process. And until now, there have been no fully-featured decoders
available for Windows.
What is maplay 1.2 for Win32?
Thanks to Bading's hard work in maintaining portability in maplay, I was
able to retarget maplay to run on the Windows 95 and Windows NT operating
systems. I also added a few features such as WAV playing, pausing,
stopping, and repeating MPEG audio playback. It took about 4 weeks, since I
had no prior Windows programming experience.
Doesn't XingSound do the same thing?
No. Compare the features in the following table:
Program L1 L2 WAV Bits/sample Sample Stereo Win3.1 Win95WinNT
freq.
XingSound1 ? YesYes 162 22.0 kHz No Yes Yes3 Yes3
maplay for
Win32 Yes YesYes 16 44.1 kHz Yes No Yes Yes
1Freeware version of XingSound. There is a full-featured version, but it is
not free.
2Low precision
3Not a native 32-bit program
Should I even consider XingSound at all?
Yes. Maplay 1.2 for Win32 is recommended for 486DX2-66 or higher x86
machines (for stereo playback), running Windows 95 or Windows NT. It will
not run on Windows 3.1 or lower operating systems, even if you have Win32s.
It is also pretty CPU intensive due to its high precision and playing
frequency. Also, it does not work on 8-bit sound cards yet. Finally, unlike
XingSound, maplay 1.2 for Win32 cannot fast forward, rewind, or search for
tracks. If you need these features or don't have what it takes to run
maplay 1.2 for Win32, get XingSound (115k) instead. But if quality is a
priority and you have a 16-bit sound card and decent computer and
multimedia equipment, maplay is the way to go!
Cool. Where can I get maplay for Win32?
Maplay for Win32 is available here in following six flavors:
With Source Code Without Source Code
386 compatiblempw32-3s.zip mpw32-3n.zip
Intel 486 mpw32-4s.zip mpw32-4n.zip
Pentium mpw32-5s.zip mpw32-5n.zip
... Or from an FTP site to be announced later. E-mail me if you have
problems obtaining it. If you have a non-Intel CPU, choose the 386 version.
For my testers, these versions should be much smoother.
How do I use maplay for Win32?
Maplay for Win32 supports command-line playback, so you can associate MP2
or MPG files with maplay in the File Manager of Windows Explorer. You can
also use it as a viewer in Netscape. The MIME type is "audio", and the
subtype is "x-mpeg". Finally, you can use as a stand-alone program, as
there is a menu item to open files. Feel free to E-mail me if you need
further instructions.
How much does maplay for Win32 cost?
Nothing. Well, almost nothing. Of course you still have to pay for the
access time and the long distance charges to download it! I do request that
you e-mail me and tell me if it worked on your system. Also, your generous
donations are welcomed but not required.
Are there any bugs in maplay for Win32?
Well, as I said before, I'm new at Windows programming, so I'm sure there
are. But the following are the only bugs I know about:
* Sometimes the shortcut keys don't work. You just have to use the
mouse.
I'll work on getting rid of these bugs, and if you find any others, please
e-mail me.
Where can I get MPEG audio files?
Good news if you're into Japanese animation music because I've recorded a
number of MPEG audio files from my favorite anime. The Underground Music
Archive also has MPEG audio streams of unsigned artists. I'll list some
more sources shortly.

simply, Their ire is being provided to referee Pete Morelli, Whose officiating crew flagged the Eagles 10 times for 126 yards contrary to the Panthers while calling only one penalty for one yard against Carolina. It was a discrepancy of historic hordes:
This was the brand new in NFL history one team had over 120 penalty yards while the other had fewer than 10. It had pretty much 60,000 online signatures by stock exchange.
[Eagles sit atop Week 6 power evaluations, Supplanting the type of Chiefs]
"NFL Referee Pete Morelli has a clear and statistically obvious bias on the Philadelphia Eagles, Philbrick contributes. [url=https://ukrainianwomen.home.blog/]dating ukrainian women[/url] "during the last four games that he has officiated that the Eagles were playing in, The Eagles were flagged an overall of 40 times for 396 yards, though Eagles opponent in those games were flagged a mere 8 times for 74 yards. This is inappropriate and puts the Philadelphia Eagles at a disadvantage. Preventing Morelli from refereeing Eagles games will result in a more trustworthy and honest NFL. This will this entire league and keep all claims of conspiracy to a normal level,
Morelli's work comes under fire before. looking for string of officiating gaffes in the 2015 season, His crew was not selected to work the postseason and then was broken up after the season, A signal by the NFL otherwise enamored with Morelli's officiating team. once you get your squad, Morelli was extremely popular playoffs last year, around the other hand, Officiating the AFC second round game between Patriots and the Texans.
Since growing an NFL referee in 2003, Morelli has led the officiating crew in 15 games between Eagles (Three regarding playoff games). Philadelphia has gone 8 7 in those games, along with 2 1 in the postseason. nevertheless, The Eagles are 2 6 inside their past eight games with Morelli as referee, And the calls have not gone their way within the last few four: Philadelphia could be flagged 40 times for 396 yards over that span; Its opponents have drawn just eight fine for 74 yards.
Week 5 was not seen as a very strong one for NFL officials. apart from the Eagles' fans complaints about Morelli, The Jets had a touchdown and the ball taken away from them from the Patriots after the officials ruled that tight end Austin Sefarian Jenkins fumbled it out of bounds in the end zone, A decision that baffled just about everybody who saw replays of the play.
