Transmitting apparatus, transmitting method, receiving apparatus, receiving method, and transmitting and receiving system

A transmitting method for transmitting a content, comprising the steps of:

• writing at least one content to a record medium;
• generating section 1 to section n (where n is an integer) in such a manner that when the content 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;
• formatting a signal in such a manner that the length of data of each of the section 1 to the section n is the same in each of channel 1 to channel n;
• multiplexing the formatted signal;
• and
• transmitting the multiplexed signal.

• separating means for separating the received signal;
• detecting means for detecting beginning data of each of the section 1 to the section n from the separated signals;
• a second record medium on which the beginning data of each of the section 1 to the section n is written to channel 1 to channel n, respectively;
• reading means for successively reading data of the section 2 to the section n from said second record medium after the beginning data of the section 1 is detected, the data of the section 1 is written to said second record medium starting from the beginning data of the section 1, the data of the section 1 is read from said second record medium, and the data of the section 1 is read from said second record medium;
• and
• reproducing means for reproducing the data of the section 1 to the section n that has been read from said second record medium.

A receiving method for receiving a signal from a transmitting apparatus and reproducing the received signal, the transmitting apparatus having a first record medium on which at least one content has been written, section generating means for generating section 1 to section n (where n is an integer) in such a manner that when the content 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, signal formatting means for formatting a signal in such a manner that the length of data of each of the section 1 to the section n is the same in each of channel 1 to channel n, multiplexing means for multiplexing the formatted signal, and transmitting means for transmitting the multiplexed signal, the receiving method comprising the steps of:

• separating the received signal;
• detecting beginning data of each of the section 1 to the section n from the separated signals;
• writing the beginning data of each of the section 1 to the section n to channel 1 to channel n, respectively, to a second record medium;
• successively reading data of the section 2 to the section n from the second record medium after the beginning data of the section 1 is detected, the data of the section 1 is written to the second record medium starting from the beginning data of the section 1, the data of the section 1 is read from the second record medium, and the data of the section 1 is read from the second record medium;
• and
• reproducing the data of the section 1 to the section n that has been read from the second record medium.
