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/. + + +This software is covered by copyrights.

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! + + +ACKNOWLEDGMENT + +We gratefully thank ARPA and the National Science Foundation for their +financial support, and thank Tektronix, Hewlett-Packard and the +Portland Trail Blazers for their donations. + +We also want to thank following people for their code: + + Lawrence A. Rowe, Ketan Patel, and Brian Smith of Computer Science + Division-EECS, Univ. of Calif. at Berkeley. The MPEG decoder used by + the client of the player is originated from their MPEG decoder 2.0 + + Thomas M. Levergood, Andrew C. Payne, James Gettys, G. Winfield + Treese, and Lawrence C.
