live video: Over time, RealVideo has become a standard for streaming video content. To set up the connection, the Real Time Streaming Protocol (RTSP), a standard protocol in content transmission, is used. The in-house RDT protocol is used for the actual data. RealVideo files are compressed like RealAudio. Newer versions still achieve good results even with higher compression, whereas older versions delivered rather poor results. RealVideo files end in .ram, rv, rm, or .rmvb for variable-name files bitrate.
