Patent ID: 8634416

Claim:
A digital broadcasting information receiving apparatus comprising: a receiving circuit receiving transmitted digital information and demodulating the received digital information into a bit stream having a predetermined packet structure, said transmitted digital information being such that a plurality of logical channel signals of at least one of video, audio, and data are multiplexed as digital information on a single bit stream having a predetermined packet format defined in MPEG-2 rule and are transmitted; a packet separating circuit extracting a designated packet from a bit stream output from an input processing circuit; a packet replacing circuit replacing at least packet IDs of the packet output from said packet separating circuit with predetermined information; an output circuit outputting an output signal from said packet replacing circuit; and a control circuit controlling operations of said packet separating circuit, wherein said packet replacing circuit includes: a temporary storage circuit temporarily storing an input signal; a detecting circuit detecting a specific signal from the signal temporarily stored in said temporary storage circuit; first storage circuit and second storage circuit storing a signal entered from said control circuit; a comparing circuit comparing the signal detected by said detecting circuit with the signal stored in said storage circuit; and a selecting circuit selecting said input signal, the signal temporarily stored in said temporary storage circuit, or the signal stored in said second storage circuit, wherein when said specific signal is a predetermined value, either a portion or all of the packets containing said specific signal are replaced by the signal stored in said second storage circuit, and wherein said selecting circuit selects said input signal, the signal temporarily stored in said temporary storage circuit, or the signal stored in said second storage circuit under control of said comparing circuit and said control circuit, and owns a first mode in which, when said specific signal is equal to a predetermined value, either a portion or all of the packets containing said specific signal is replaced by the signal stored in said second storage circuit, and also owns a second mode in which either a portion or all of the packets containing said specific signal is replaced by the signal stored in said second storage circuit irrelevant to the value of said specific signal under control of said control circuit.
