Abstract: Congested rewriting in the same area is to be evaded to suppress the tendency towards occurrence of defective areas. When a stream 1 has been recorded, the last written address, representing the last written position, is stored. When recording a stream 2 next, recording is started directly following the position indicated by the last written address for the stream 1. The last written address, corresponding to the last address of the recording position, is stored. If the stream 2 is erased for recording a stream 3, recording is started not at a position directly following the last written address of the stream 1, but from a position directly following the last written address of the stream 2. When the stream 3 has reached the end of a recording area, the next following data is recorded as from a position directly following the stream 1.

Abstract: Cuando se graban datos en un medio en el cual se requiere un cierto régimen de datos, un administrador de asignaciones en el reproductor debe asignar secciones del espacio logico en forma tal que el medio de grabacion sea llenado eficientemente y que se pueda garantizar un régimen de datos adecuado aun en la presencia de bloques ECC defectuosos. Las reglas de asignacion para el administrador de asignaciones son complejas. Las reglas pueden ser simplificadas colocando un límite inferior en el tamano de una extension y aumentando el tamano de la extension dependiendo de la cantidad de bloques ECC defectuosos en la extension.

Abstract: For encoding externally input AV signal to MPEG-TS that enables quickly conversion from MPEG-TS to MPEG-PS, data unit (Multiplexing Unit) is defined which includes a plurality of packet and has data size corresponding to data amount of one pack in MPEG-PS, and MPEG-TS is encoded for each defined data unit. Furthermore, time stamp information (ATS) added to a packet of MPEG-TS which is converted to MPEG-PS and time stamp information (SCR) added to a packet of the converted MPEG-PS are correlated with a predetermined formula.

Abstract: In a recording medium storing MPEG stream, flag information (encode_condition) indicating that the stream is recorded in a format enabling easily the first stream (MPEG transport stream) to be converted into the second stream (MPEG program stream) is provided. Such a flag information is included in Tip packet which is a control packet, in the medium. Thus it can easily determine whether the data is recorded in this format without analysis of data stored in the recording medium.

Abstract: The characteristic playback domain of an AV stream is to be reproduced simpl y and reliably without complicating the management. As marks representing characteristic points of an AV stream, a mark of the type indicating a point and a mark of the type indicating a section (duration) are provided. The mar k of the type indicating a point designates a point with a time stamp corresponding to a preset playback timing of the AV stream. The mark of the type indicating a section specifies the domain based on the time stamp of th e playback start point of the preset playback domain of the AV stream and on t he duration as from the playback start point until the playback end point.

Abstract: A method for recording video information for controlling video information copy limit information when copying data recorded on a recording medium to another recording medium. By detecting copy limit information (CCI) or a watermark (WM) of an AV stream to be input, it is checked whether the conten t of the copy limit information or the watermark has been changed. Change poin t information of the copy limit information or the watermark and the content o f the copy limit information or the watermark are fetched. According to the change point information fetched, control information is generated for controlling the copy limit information. When the input signal has ended, a code for preventing altering is calculated, it is confirmed that the copy limit information or the watermark has not been altered, and the control information generated is recorded together with the video information to the recording medium of copy destination.
