In a video/audio coding and multiplexing method, coding of multimedia data including video data and audio data is implemented as a software program operating on a multitask operating system, and video/audio coded and multiplexed information in which video/audio synchronization is realized in specified time units is obtained. In this method, coded video information and coded audio information are temporarily stored in a video buffer and an audio buffer, respectively. A video/audio synchronization means creates time and information using video block rate information which is created on the basis of the coded video information and stored with the coded video information. According to the time information, a coded video read-out means and a coded audio read-out means read the coded video information and the coded audio information from the respective buffers, and the video/audio synchronization means performs video/audio multiplexing. Thereby, the coding process and the multiplexing process are performed at independent timings.

Disclosed is a recording device for recording data in a recording/reproduction device using a recording medium in which the recording-rate performance showing the recordable data quantity per unit time varies area to area. The recording device comprises a data memory unit for temporarily storing data to be recorded; a data quantity management unit for managing the quantity of data in the memory unit, and requesting execution of writing data in the recording medium; a medium area management unit for managing an available area in the recording medium, and deciding a data write position; and a data transfer control unit for controlling transfer of data from the data memory unit to the recording/reproduction device according to the write position generated by the medium area management unit. The medium area management unit includes an area-division management section for dividing the recording medium into plural speed areas of different recording-rate performances, and managing the speed areas. The data quantity management unit includes a recording rate control unit for setting a rate of recording the data stored in the data memory unit according to the quantity of the data stored in the data memory unit. The speed areas on which data are to be recorded are switched on the basis of the recording rate set by the recording rate control unit. Therefore, the medium is used efficiently without being restricted by the recording-rate performance of a lower-speed area in the medium.

摘要:
A method of coding a moving picture in which the moving picture is input and coded to produce coded data comprises a picture capturing step for capturing a picture at time n..DELTA.t (n: integer .DELTA.t: time interval) of an input moving picture as a still picture and outputting still picture data; a time information producing step for outputting time information corresponding to time n..DELTA.t when the moving picture is captured as the still picture in the picture capturing step; and a coding step for sequentially capturing and coding the still picture data output in the picture capturing step, computing a time interval between two continuous still pictures in capturing time of the captured still picture data using the time information output in the time information producing step, and when the computed time interval is m..DELTA.t, (m: integer, m.gtoreq.2), inserting coded data corresponding to (m-1) or less still pictures between coded data and coded data of the two still pictures so that the time interval between coded still pictures is set to be constant.
