<P>PROBLEM TO BE SOLVED: To provide a video transmitting apparatus capable of switching digital videos at a high speed without preparing a large information table for a decoder, and to provide a video transmitting system. <P>SOLUTION: Video data generated in a video coding section 1 are outputted to a sequence information extracting section 2. The section 2 extracts sequence information from a stream, and stores the sequence information in a sequence information storing section 5. Usually, a stream is sent out from a network IF 4 to a network, passing by a sequence information inserting section 3. When the decoder requests to switch video, the decoder issues a sequence information request trigger to an encoder. The sequence information request trigger is received by the network IF 4 and recognized by a CPU 6. When the CPU 6 recognizes the sequence information request trigger, the sequence information stored in the section 5 is inserted into the stream from the section 3. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
