Receiving apparatus of digital broadcasting and display method of recording program associated information

A receiving apparatus for receiving a digital broadcasting signal constructed by a transport stream in which video data and audio data have been compressed and multiplexed, comprising:

• a decoder for decoding said received digital broadcasting signal;
• a digital interface for receiving a transport stream from a reproducing apparatus;
• and
• a display processing circuit for displaying information associated with a program recorded in a predetermined compression format on a recording medium loaded in said reproducing apparatus,
• wherein the decoder is (i) for determining whether the transport stream corresponding to the program recorded on the recording medium reproduced by said reproducing apparatus and received through said digital interface is decodable by said decoder using a predetermined coding system used at the receiving apparatus to decode a transport stream, and (ii) for generating decodability data indicating a result of determining whether the transport stream corresponding to the program recorded on the recording medium reproduced by said reproducing apparatus and received through said digital interface is decodable by said decoder using the predetermined coding system;
• wherein in the case where the decodability data indicates the transport stream corresponding to the program recorded on the recording medium reproduced by said reproducing apparatus and received through said digital interface is determined not able to be decoded in said decoder using the predetermined coding system, said display processing circuit performs a display process so as to display a message based on the decodability data and showing that the program recorded on the recording medium loaded in said reproducing apparatus is recorded in a compression mode in which said transport stream corresponding to the program recorded on the recording medium reproduced by said reproducing apparatus and received through said digital interface cannot be decoded by said receiving apparatus using the predetermined coding system;
• wherein said information associated with said program is overlapped to a reproduction signal from said reproducing apparatus and displayed.

A receiving apparatus for receiving a digital broadcasting signal constructed by a transport stream in which video data and audio data have been compressed and multiplexed, comprising:

• a decoder for decoding said received digital broadcasting signal;
• a digital interface for receiving the transport stream from an external reproducing apparatus;
• and
• a display processing circuit for displaying information associated with a program recorded in a predetermined transport stream format on a recording medium loaded in said reproducing apparatus,
• wherein the decoder is (i) for determining whether the transport stream corresponding to the program recorded on the recording medium reproduced by said reproducing apparatus and received through said digital interface is decodable by said decoder using a predetermined coding system used at the receiving apparatus to decode a transport stream, and, (ii) for generating decodability data indicating a result of determining whether the transport stream corresponding to the program recorded on the recording medium reproduced by said reproducing apparatus and received through said digital interface is decodable by said decoder using the predetermined coding system;
• wherein in the case where the decodability data indicates the transport stream corresponding to the program recorded on the recording medium reproduced by said reproducing apparatus and received through said digital interface is determined not able to be decoded in said decoder using the predetermined coding system, said display processing circuit performs a display process so as to display a message based on the decodability data and indicating that the program recorded on the recording medium loaded in said reproducing apparatus is recorded in a format wherein said transport stream corresponding to the program recorded on the recording medium reproduced by said reproducing apparatus and received through said digital interface cannot be decoded by said receiving apparatus using the predetermined coding system;
• wherein said information associated with said program is overlapped to a reproduction signal from said reproducing apparatus and displayed.

A display method of recording program associated information in a receiving digital broadcasting signal constructed by a transport stream in which video data and audio data have been compressed and multiplexed, comprising:

• receiving a digital broadcasting signal constructed by a transport stream in which video data and audio data have been compressed and multiplexed;
• decoding said received digital broadcasting signal;
• receiving the transport stream from an external reproducing apparatus through a digital interface;
• reading out information associated with a program recorded on a recording medium loaded in said reproducing apparatus from a memory in said reproducing apparatus;
• displaying the information associated with the program recorded on the recording medium loaded in said reproducing apparatus by a predetermined format;
• determining whether the transport stream corresponding to the program recorded on the recording medium reproduced by said reproducing apparatus and received through the digital interface is decodable using a predetermined coding system used at the receiving apparatus to decode a transport stream;
• and
• generating decodability data indicating a result of determining whether the transport stream corresponding to the program recorded on the recording medium reproduced by said reproducing apparatus and received through the digital interface is decodable using the predetermined coding system,
• wherein in said displaying the information, when the decodability data indicates the transport stream corresponding to the program recorded on the recording medium reproduced in said reproducing apparatus and received through the digital interface is determined not able to be decodable using the predetermined coding system in said determining step, a display process is performed so as to display a message based on the decodability data and showing that the program recorded on the recording medium loaded in said reproducing apparatus is recorded in a recording mode in which the transport stream corresponding to the program recorded on the recording medium reproduced in said reproducing apparatus and received through the digital interface cannot be decoded using the predetermined coding system;
• wherein said information associated with said program is overlapped to a reproduction signal from said reproducing apparatus and displayed.
