Patent ID: 7478415

Claim:
A digital broadcast receiving system comprising: a receive and demodulation section by which a digital broadcast signal received from the exterior is demodulated and outputted as a packet stream; a packet filter that filters a predetermined packet in a plurality of packets composing said packet stream; a record and reproduction unit by which said packet stream passing through said packet filter is recorded, and said recorded packet stream is reproduced and outputted; an information table generator for generating a predetermined information table; an output information insertion unit by which said predetermined information table is inserted to said packet stream outputted from said record and reproduction unit, thereby to output it as a new packet stream; and a circuit changing switch that performs a selective switching between said packet stream outputted from said receive and demodulation section, and said new packet stream outputted from said output information insertion unit, thereby performing its transmission to a digital output section wherein, said packet stream recorded in said record and reproduction unit does not conform to a predetermined standard, and said new packet stream is made to conform to said predetermined standard by inserting said predetermined information table, wherein, said information table generator has a function with which the PID value of an ES to be described is subjected to an arbitrary alteration, to generate said predetermined information table; and said output information insertion unit has a function with which the value obtained by said alteration to said PID value is substituted for the PID value of a packet transmitting an ES contained in said packet stream transmitted wherein, said information table generator has a function with which the value of a program number of a program recorded in said record and reproduction unit is subjected to an arbitrary alteration, to generate said predetermined information table; and said output information insertion unit has a function with which the value obtained by said alteration to said program number is provided to said packet stream transmitted.
