Abstract: The present invention is to provide a digital video-audio signal recording and reproducing apparatus that allows the number of channels of audio data and the data width per sample to be changed corresponding to user's settings. 24-bit/sample audio data that is input as serial data to Ch 1 of the digital video-audio signal recording and reproducing apparatus is separated into high order 16 bits and low order eight bits. The high order 16 bits are recorded in a region of Ch 1 of a record medium. The low order eight bits are stored to a region of low order eight bits of Ch 3 paired with Ch 1 of the record medium. Mode information that represents that 24-bit data is separated into paired channels is added to record data each edit unit of video data. When dat is reproduced, data of paired channels is combined corresponding to the mode information so as to restore 24-bit data. Since the 24-bit data is treated as 16-bit data, the record format of 16-bit data can be used for the 24-bit data.

Abstract: A shuffling table memory has a shuffling table written from an external memory through a path. The external memory stores a plurality of shuffling tables corresponding to the formats of video data to be shuffled. One shuffling table selected according to the result of format determination is stored in the shuffling table memory. The shuffling table memory receives an IDi separated from the input data as an address and outputs a converted address IDo. The address IDo generated by the shuffling table memory is used as a write address for writing data into a data-accumulation memory. With the read address sequentially changing, shuffled data is read from the data accumulation memory.

Abstract: On the basis of encoding condition and encoding difficulty parameter of material inputted at steps S31, S32, stability of pull-down pattern is calculated at step S33. The stability of the pull-down pattern is judged at step S34. In the case where the pull-down pattern is not stable, warning is displayed at step S35. At step S36, whether or not encode processing by the original condition is continued is judged. In the case where processing is not continued, encode processing without pull-down processing, etc. is carried out at step S44. In the case where processing is continued or it is judged at step S34 that pull-down pattern is stable, scene change detection/processing, chapter boundary processing, interpolation/correction processing of encoding difficulty, calculation of No. of target bits and address calculation are carried out at steps S37 to S41. Target rate is calculated at step S42. Control file for encoder is prepared at step S43. Processing is thus completed.
