IPC: H04N7/16
Filed: 1997-11-20
Abstract: PROBLEM TO BE SOLVED: To prevent the configuration and stream of a recorded program from being impaired by discriminating the validity of data on emergency among separated data streams and generating an emergency data reproduction stop signal, when the loss of validity is discriminated, thereby stopping the decoding or multiplexing of the data on emergency. SOLUTION: When broadcast program data include on-emergency data, an external control multiplexer means 29 outputs the on emergency data to audio and video output means 30, 31. A stream separate means 26 separates broadcast time data and generates an on emergency data detection signal when the on- emergency data is detected and an on-emergency data detection time confirmation means 33 generates the time data of this signal detection. When the time difference between the time data and the broadcast data is larger than a prescribed time, a multiplex stop signal for the on-emergency data is generated for the external control multiplexer means 29 for making the priority multiplex output function of the external control multiplexer means 29 stopped.
