Broadcasting equipment and method, receiving equipment and method, and medium

A method for receiving a transport stream obtained by repeatedly multiplexing a plurality of contents data, characterized by comprising:

• step of reading predetermined information corresponding to the contents data from the transport stream;
• step of receiving designation of the contents data from the user;
• and
• step of determining order of extracting a plurality of contents data corresponding to the designation from the user received in the receiving step from the transport stream with reference to the predetermined information read in the reading step on the basis of a predetermined algorithm.

Receiving equipment for receiving a transport stream obtained by multiplexing plural encoded data encoded by different systems, comprising:

• first extracting means for extracting first encoded data from the transport stream received;
• first outputting means for outputting the first encoded data extracted by the first extracting means;
• second extracting means for extracting second encoded data from the transport stream received;
• decoding means for decoding the second encoded data extracted by the second extracting means to thereby generate audio data;
• and
• second outputting means for outputting the audio data generated by the decoding means.

A method for receiving a transport stream obtained by multiplexing plurally encoded data encoded by different systems, comprising:

• a first extracting step of extracting first encoded data from the transport stream received;
• a first outputting step of outputting the first encoded data extracted in the first extracting step;
• a second extracting step of extracting second encoded data from the transport stream received;
• a decoding step of decoding the second encoded data extracted in the second extracting step to thereby generate audio data;
• and
• a second outputting step of outputting the audio data generated in the decoding step.
