Abstract
With a first-transition detecting circuit for receiving a synchronism detection signal indicating the state where synchronism of a digital signal has been established and outputting a pulse, a flip-flop for receiving this pulse and outputting a flag signal of “H” level, and logic gates, when a TMCC decoding complete signal indicating completion of a TMC signal is generated the TMCC signal inputted into a buffer anew is written in a register, and this TMCC signal is used for decoding a data stream. Then, in the state where synchronism of a digital signal has been established, updating of a TMCC signal is executed in response to output of a signal from a comparing circuit indicating inconsistency between updating instruction information newly inputted and updating instruction information already stored.
Claims15
A receiving apparatus comprising:
- a receiver for receiving a digital signal with a plurality of data streams each based on a different transfer system, data configuration control signal indicating a transfer system, configuration and location of each of the data streams, and updating instruction information for instructing updating of the data configuration control signal multiplexed therein;
- a decoder for decoding the data streams using the updated data configuration control signal;
- a synchronism detecting unit for detecting synchronism of the digital signal and outputting a synchronism detection signal indicating the synchronous state;
- a decoding complete signal outputting unit for outputting a decoding complete signal indicating that decoding of the data configuration control signal is complete;
- and
- a data configuration control signal updating unit for updating the data configuration control signal in the state where the synchronism detection signal outputted from said synchronism detecting unit has been inputted, when a decoding complete signal outputted from said decoding signal outputting unit is inputted first after the synchronism detection signal is inputted.
