Abstract
The present invention relates to transmitting a coded video signal, wherein the video signal is preferably an MPEG-4 video signal including a base layer and an enhancement layer. The present invention comprises a first coding unit for coding the video signal into a first stream, a second coding unit for coding the video signal into a second stream, a layer-combining multiplexing unit for combining the first and second streams into one stream; and a real-time transport protocol (RTP) packetization unit for packetizing the combined stream, wherein the packetized combined stream has an RTP header.
Claims18
A video transmission apparatus for transmitting a coded a video signal, comprising;
- a first coding unit for coding a video signal into a first stream;
- a second coding unit for coding the video signal into a second stream;
- a layer-combining multiplexing unit for combining the first and second streams into one stream;
- and
- a real-time transport protocol (RTP) packetization unit for packetizing the combined stream, wherein the packetized combined stream has an RTP header.
A method for transmitting a coded video signal, the method comprising:
- coding a video signal into a first stream;
- coding the video signal into a second stream;
- combining the first and second streams into one stream;
- and
- packetizing the combined stream, wherein the packetized combined stream has a real-time transport protocol (RTP) header.
A video transmission apparatus for transmitting a coded video signal, comprising;
- a first coding unit for coding a video signal into a first stream;
- a second coding unit for coding the video signal into a second stream;
- a first real-time transport protocol (RTP) packetization unit for packetizing the first stream, wherein the packetized first stream has a first RTP header;
- and
- a second real-time transport protocol (RTP) packetization unit for packetizing the second stream, wherein the packetized second stream has a second RTP header.
