Abstract: PROBLEM TO BE SOLVED: To extract header information in an excellent way even when packets are transmitted through a deteriorated transmission channel thereby reducing number of aborted packets due to inability to read a multiplex table. SOLUTION: A multiplexer section at a transmitter side estimates an information amount from each signal processing section (S1), a multiplexing code is decided based on each information amount (S2), parity of a decided (1st) multiplexing code is taken, the result is used for a 2nd multiplexing code, CRC is added to each multiplexing code respectively to generate two headers H1, H2 (S3), information data of each medium are extracted in matching with the multiplexing code (S4), the data are assembled with a packet in matching with the two headers H1, H2 and the result is outputted (S5). In this case, the receiver side uses the header H2 when the error correction of the H1 is unable, and error correction is conducted with the H1, H2 when the error correction of the H2 is unable, and then unable reading of the multiplexing codes is reduced.

Abstract: PROBLEM TO BE SOLVED: To utilize the system stably and to easily simplify the system by configuring the system such that video radio transmitter-receiver sets with spread spectrum processing use a very weak radio wave for the transmission and reception so as to avoid interference between the radio waves. SOLUTION: A video camera 11 picks up an image inside a vacant room 4 and outputs a coded and compressed digital video signal to a transmitter 12.
