RealVideo is a proprietary video compression standard developed by Real Networks. It was developed with particular attention to situations where it would be streamed over the internet. Initial versions were based on the H.263 compression standard, the current version (RealVideo 10), is proprietary to Real Networks.
Details
Real Networks claims that RealVideo 10 can provide similar video quality to other video compression standards, at a lower bit rate. HDTV quality can be encoded at rates less than 5MBps. RealVideo 10 is backwards compatible with RealVideo 9 players, as it is an encoder based improvement over RealVideo 9, producing a file which decodes with the same decoder. RealVideo implements pixel-prediction techniques in its algorithm.[1]
Implementations
RealVideo can be played natively in RealPlayer, created by Real Networks. It is typically contained in the RealMedia container, also created by Real Networks.[1] Other players typically require access to the official codecs provided by installing RealPlayer to decode RealVideo files.
