Patent ID: 7333715

Claim:
A data reproduction transmission apparatus comprising: reproduction means for reproducing multiplexed video information coded according to a predetermined information processing rule to provide multiplexed coded data; decoding means for decoding the multiplexed coded data to generate decoded data; supplying means for supplying the multiplexed coded data or decoded data generated by decoding the multiplexed coded data and that includes at least the video information; data restructuring means for restructuring the multiplexed coded data or the decoded data to restructured coded data that conforms to a predetermined transmission format, and including: image extraction means for extracting an intra picture from the multiplexed coded data, and image interpolation means for interpolating B picture or P picture between extracted intra pictures; and output means for supplying the restructured coded data for digital transmission; coding means for re-coding the data generated by decoding the multiplexed coded data so that the re-coded data is acceptable for a digital signal processing apparatus, and multiplexing means for multiplexing the re-coded data with the multiplexed coded data.
