Method for Transferring High Resolution Multimedia Data in a High Speed Network, Server Apparatus and Client Apparatus for Use in the Method

摘要

In video production sites, video material is stored on video servers in digital form. High speed networks are available for transferring video content from the video servers to workstations for post-processing like video editing, colour management etc. Most networks and a lot of software for post-processing are available for exchanging data with Internet protocol. Extensions for the RTP protocol are available for transporting high definition video/audio data based on an Internet Protocol stack. The invention enables the overall control of the data streaming by setting two incompatible flags (405, 406) in one and the same RTP packet without the need of a further extension of the RTP protocol. In one example the end of a data stream is signalled by setting the frame begin plus frame end flag (405, 406) in the packet transporting the last part of the last DPX frame in the stream.
