VARIABLE-LENGTH FRAME TRANSMISSION DEVICE, AND VARIABLE-LENGTH FRAME TRANSMISSION METHOD

摘要

In the cases where a SB insertion judgement section 124 multiplexes voice information to next frame, the SB insertion judgement section 124 calculates multiplex available length of video information while subtracting length of a synchronization code word and a header from distance between a termination of a front frame and multiplex start position of voice information. The SB insertion judgement section judges that it is necessary to multiplex stuffing bit sequence when length of important information is longer than multiplex available length. In this case, a frame configuration section inserts redundant bit in between terminal position of the front frame and the front position of the synchronization code word. Thereby, it is capable of preventing the matter that the important information is divided into a plurality of frames on the occasion of multiplexing transmission data.
