Patent ID: 7158538

Claim:
A transmitting apparatus for transmitting a content program, comprising: a record medium on which at least one content program has been written is stored; section generating means for generating a section generator that divides the content program into sections, section 1 to section n (where n is an integer) in such a manner that when the content program is divided into the section 1 to the section n in a predetermined ratio, the length of a section on the beginning side is smaller than the length of a section on the end side section n is longer than the length of section 1 ; signal formatting means for formatting a signal formatter that formats a signal in such a manner that the length of data of each of the section 1 to the section n in the content program is the same in each of channel 1 to channel n; multiplexing means for multiplexing a multiplexer to multiplex the signal formatted by the signal formatter; and transmitting means for transmitting a transmitter to transmit the multiplexed signal, wherein said section generating means generator divides the content program so that a ratio of the lengths of the section 1 to the section m (where 1<m<n: m is an integer) become is 1, 2, 4, . . . , 2( m−1 ), respectively, and that wherein the length of each of the section m to the section n is the same as the length of the section m.
