+ Distributed real-time MPEG video audio player v2.0
+
+ Distributed Systems Research Group
+ Department of Computer Science and Engineering
+ Oregon Graduate Institute of Science & Technology
+ November, 1995
+
+
+This directory contains a freely available software distributed
+real-time MPEG video and audio player, for use across the
+Internet. Please install it, run it, play movies and music, and have
+fun !
+
+The player features common VCR functionalities like synchronized video
+and audio play back, play speed change on the fly, fast-forward, rewind,
+step forward, random Positioning, and more.
+
+This version of the player plays MPEG1 video (elementary stream) and
+Sun Sparc format (mu-law) audio. It does not play MPEG1 system streams
+or MPEG2 streams yet.
+
+The player is of server/client architecture, with audio/video servers
+and a client distributed across the Internet. The server manages audio
+video file retrieval and distribution. The client decodes video
+frames, plays video and audio streams, and provides a Motif style user
+interface.
+
+The servers stream out media data to clients, so there is NO NEED to
+download all bits beforehand.
+
+Some important characteristics of Internet are resource sharing,
+highly dynamic workload, no resource reservation facility, and lack of
+a common clock. This player uses novel software feedback mechanisms
+to synchronize servers and clients, and to adapt playback quality to
+the current Internet workload.
+
+
+As compared to version 1.0, this version has following improvements:
+
+ - UDP/TCP video audio data connection choice
+ - support of both native audio device and AudioFile
+ - client invocable from web browser
+ - better organized source code tree
+ - bug fix
+ - and more...
+
+
+The player has been compiled and tested on following architectures:
+
+ HP-UX 09.03
+ SunOS 4.1.3_U1 (sparc)
+ Solaris 2.3 (sparc)
+ Solaris 2.4 (i86pc)
+ Solaris 2.4 (sparc)
+ Ultrix 4.x
+ FreeBSD 2.0.5
+ LINUX 1.3
+
+If you decide to port the player to a new architecture, please let
+us know so that we can incorporate the changes into our sources.
+
+
+The player is publicly available via anonymous ftp from:
+
+ ftp.cse.ogi.edu (129.29.20.2) in /pub/dsrg/Player/
+
+or through following WWW pointer:
+
+ http://cse.ogi.edu/DISC/projects/synthetix/Player/
+
+To install the player, ftp file vcr.tar.Z to local host, move it to a
+suitable directory (best to create a new directory for this software),
+uncompress and untar the .Z file, and see INSTALL for instructions.
+Following is an example of steps to ftp and untar the package:
+
+ % mkdir vcr
+ % cd vcr
+ % ftp ftp.cse.ogi.edu
+ *** login as anonymous and your email address as passwd ***
+ ftp> cd pub/dsrg/Player
+ ftp> binary
+ ftp> get README
+ ftp> get vcr.tar.Z
+ ftp> quit
+ % gunzip vcr.tar.Z (or you may also use 'uncompress vcr.tar.Z')
+ % tar xf vcr.tar
+
+Binary code for platforms HPUX, Solaris 2.4 for x86, Solaris 2.x for
+Sparc, SunOS4.1.3 and FreeBSD are also available in directory
+/pub/dsrg/Player/binaries/.

+
+
+We would highly appreciate it if you can share with us the performance
+result you get when you play movies retrieved from the OGI
+server. Please let us know following information:
+
+ - The platform you use for the client.
+
+ - How many hops from your site to OGI, and what is the
+ estimated bandwidth,
+
+ - Which picture size (320x240, 256x192, 128x96 or 64x48)
+ works best for you, and on average how many
+ frames-per-second can be displayed.
+
+ - Questions, comments, suggestions, and bug report.
+
+Information can also be sent to: scen@cse.ogi.edu Thank you!
