Abstract: A power control section 105, which turns ON or OFF a video/audio recording apparatus, outputs power control information. A video recording control section 107, which starts or stops video recording, outputs video recording control information. A signal input section 101 allows moving picture data to be input. Based on the power control information and the video recording control information, an attribute designation section 109 generates attribute information, which is supplied to a recording section 103. The attribute information contains a program number used for the classification of moving picture files. Any number of moving picture files which may be recorded after the power is turned ON and before the power is turned OFF are assigned with the same program number. The recording section 103 records on a recording medium the attribute information as well as moving picture files representing the moving picture data which has been input via the signal input section 101.

Abstract: In a video processing method, plural pieces of digital data such as video and audio data are inputted together with an instruction signal indicating whether the plural pieces of digital data are to be multiplexed or not, and the plural pieces of digital data are multiplexed when the instruction signal instructs to multiplex the digital data, and then the multiplexed digital data are outputted together with a flag indicating whether the digital data are multiplexed or not. Therefore, when video and audio data are not multiplexed or when there is a scene description for handling plural pieces of video data, the video and audio data can be recorded or transmitted in like manner as multiplexed data.
