From: ruben () europa ee uts edu au (Ruben Gonzalez) Newsgroups: alt.binaries.multimedia,alt.binaries.pictures.misc Subject: New Video compression demo A demonstration of SDDV, a real-time, full colour, software only video player is now available. Originally the first version of this codec was called RISC video, SDDV however is a new generation algorithm which is better in all ways. Existing software only video players are either low definition, or they only support very low frame rates or they have terrible compression. Other schemes have a fixed colour maps and dither which mean that the image quality is somewhat suspect. This all comes down to low quality video which requires a lot of storage space for only a short video segment. We aim to solve these problems with our new technique. We get high quality images with up to 80:1 compression (and rising, average 40:1) and frame rates of up to 200+ frames per second (average 70fps) on a standard 486 IBM PC with a standard VGA card, ISA bus. No fancy anything is required. This technique is still in the process of development and so this demo does not really demonstrate the ultimate performance we will attain. Seeing as we are a University, we are not geared for the commercialisation of this research. So we are on the look out for commercial partners interested in developing this further. If you are interested in this project and/or helping us out we are interested in hearing from you.

(I'm open to any suggestions) How to get it ? --------------- This demo can be obtained via anonymous ftp from : rcc.ee.uts.edu.au Under the directory /pub/PC/sddv ie type %ftp rcc.ee.uts.edu.au ftp> bin ftp> prompt ftp> cd pub/PC/sddv ftp> mget * Running The Demo ---------------- This demo comes in a few files; two versions of the SDDV video player and some short video clips as well as this README file. This demo will only work on 386/486 based PCs with VGA cards to play the demo movies under dos just type : "sddv movie_file" The video clips are mainly 150 frames long each of 176x144 pixels in size. The SDDV video demonstration will run on a standard VGA card. It runs in the 256 colour 320x200 mode. However the most appropriate mode to view the demo is at 640x400 mode in 256 colours and this would improve the quality substatially. Unfortunately I have not as yet written a VESA compliant decoder for SVGA boards since I don't have a copy of the standard. The windows version of the player "WinSDDV" will run under windows version 3.X. It is only a very early pre-alpha version and will only play the video files. Most of the features have not been implemented yet, and is only being released for you to experiment with. Sorry, but we haven't had the resources yet to finish the MS Windows port yet because I have been simultaneously working on a Machintosh QuickTime port as well, which is not completed yet.
