Abstract
This invention relates to a recording apparatus for recording digital data compressively encoded by use of a predetermined scheme having: receiving means for receiving a transport stream from an external unit connected through a digital bus; extracting means for extracting from the received transport stream a transport stream packet having a predetermined packet identification (PID); acquiring means for acquiring the compressively encoded digital data arranged in the transport stream packet extracted by the extracting means; and recording means for recording the acquired digital data onto a predetermined recording medium.
Claims20
A recording apparatus for recording digital data compressively encoded by use of a predetermined scheme comprising:
- receiving means for receiving a transport stream from an external unit connected through a digital bus;
- extracting means for extracting from the received transport stream a transport stream packet having a predetermined packet identification (PID);
- acquiring means for acquiring said compressively encoded digital data arranged in said transport stream packet extracted by said extracting means;
- and
- recording means for recording the acquired digital data onto a predetermined recording medium;
- whereby said transport stream further includes second compressively encoded digital data formed by compressively encoding said digital data according to a second predetermined scheme;
- whereby said transport stream is a Motion Picture Experts Group (MPEG) type transport stream, said first predetermined scheme is a non-MPEG scheme, and said second predetermined scheme is an MPEG scheme;
- and
- whereby data encoded according to said first predetermined scheme includes audio data and data encoded according to said second predetermined scheme includes said audio data, said audio data being transmitted a multiple of times in both said data encoded according to said first predetermined scheme and data encoded according to said second predetermined scheme, and the number of multiple times of said audio data according to said first predetermined scheme is greater than the number of multiple of times of said data encoded according to said second predetermined scheme.

A digital broadcast receiving apparatus for receiving a digital broadcast signal comprising:
- selecting means for selecting a desired transmission channel from the received digital broadcast signal;
- demodulating means for demodulating a transport stream transmitted by the selected transmission channel;
- extracting means for extracting a transport stream, which is data to be downloaded, from the demodulated transport stream and supplying the extracted transport stream to a recording unit through a digital bus;
- and
- if the recording of said transport stream is stopped in said recording unit, receiving means for receiving notification thereof;
- whereby said transport stream includes first compressively encoded digital data formed by compressively encoding digital data according to a first predetermined scheme and second compressively encoded digital data formed by compressively encoding said digital data according to a second predetermined scheme;
- whereby said transport stream is a Motion Picture Experts Group (MPEG) type transport stream, said first predetermined scheme is a non-MPEG scheme, and said second predetermined scheme is an MPEG scheme;
- and
- whereby data encoded according to said first predetermined scheme includes audio data and data encoded according to said second predetermined scheme includes said audio data, said audio data being transmitted a multiple of times in both said data encoded according to said first predetermined scheme and data encoded according to said second predetermined scheme, and the number of multiple times of said audio data according to said first predetermined scheme is greater than the number of multiple of times of said data encoded according to said second predetermined scheme.
