ABSTRACT:
A digital TV broadcasting signal is demodulated to obtain a bit stream containing at least a first packet of a first program specific information concerning all TV programs conveyed by the digital TV broadcasting signal and first packets of the TV programs themselves. Selection data is entered for selecting at least one of the TV programs. In response to the selection data, only second packets are selected from among the first packets. The second packets contain only data of the selected TV program. The second packets are decoded. Further, the first packet and the second packets are output without decoding and accepted. The first program specific information is modified into a second program specific information concerning the selected at least one of the TV programs. The modification is executed after the first packet and the second packets are output. Or, the modification is executed before the first packet and the second packets are accepted.
