Abstract:
1. A recording apparatus that receives an uncompressed digital video signal and records video data to a recording medium using the received uncompressed digital video signal, the recording apparatus comprising: a compression unit operable to compress the uncompressed digital video signal frame-by-frame to generate compressed video data; a record unit operable to, in accordance with a predetermined selection method for selecting which of the compressed video data and uncompressed video data of the uncompressed digital video signal to record, successively (i) select a piece of the compressed video data or the uncompressed video data, (ii) add time information to a predetermined unit of the selected piece of video data to indicate a display timing of the selected piece of video data, and (iii) record the selected piece of video data to the recording medium such that whether the selected piece of video data is compressed or uncompressed is identifiable; and a judgment unit operable to, with use of the compressed video data and the uncompressed video data, judge frame-by-frame whether the compression unit has performed the compression of the uncompressed digital video signal such that an image quality of the compressed video data is greater than or equal to a predetermined reference image quality, wherein the predetermined selection method is a method for selecting (i) to record a piece of the compressed video data when the judgment unit judges affirmatively, and (ii) to record a piece of the uncompressed video data when the judgment unit judges negatively, and wherein the record unit selects the piece of the compressed video data or the piece of the uncompressed video data, adds the time information to the predetermined unit of the selected piece of video data to indicate the display timing of the selected piece of video data, and records the selected piece of video data to the recording medium in a transport stream format such that whether the selected piece of video data is compressed or uncompressed is identifiable.
