摘要

In the transmission apparatus of the present invention, the information amount of an input information signal is compressed by a compressing means 4 and output for every constant information unit. Plural units of the output signals of the compressing means 4 are collected, and one synchronizing signal is added thereto by a synchronizing signal adding means 5. The output signal of the synchronizing signal adding means 5 is transmitted to a transmission line 6. In the receiving apparatus of the present invention, one synchronizing signal and plural units of compressed information signals are received as one set information unit, and the synchronizing signal is eliminated from the received signal by a synchronizing signal eliminating means 7. Compressed video signals among the output signals of the synchronizing signal eliminating means 7 are decompressed for every unit. With the above-mentioned system, plural information signals can be included in one set information unit, whereby information signals can be transmitted efficiently.
