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: A method is provided for recording video information in which copy control information of video information is managed in the case of copying the content of data from one recording medium to another recording medium. Copy control information (CCI) or a watermark (WM) of an inputted AV stream is detected and whether the content of the copy control information or watermark has changed is determined. Change point information of the copy control information or watermark and the content of the copy control information or watermark are acquired, and management information for managing the copy control information is generated on the basis of the acquired change point information. The generated management information is recorded together with the video information to a recording medium at a copy destination.

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 as 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: An apparatus and a record carrier for, and a method of recording a sequence of video data signals An apparatus for recording a sequence of video data signals on a record carrier has been proposed. The apparatus comprises input means for receiving video data signals, generating means for generating characteristic point information signals, processing means for processing the characteristic point information signals for a plurality of characteristic points into a sequence of characteristic points information signals (CPI) and writing means for writing the sequence of video data signals and the sequence of characteristic points information signals on the record carrier. The characteristic point information signals identify a characteristic point in the sequence of video data signals. Various measures are proposed in relation to the CPI aiming at providing compact way of storing information related to a size of I-pictures.

Abstract: In a data processing apparatus used for a multi-channel digital television broadcasting system, coded streams are recorded on a recording medium (21) with high efficiency, and can be random-accessed at high speed. The data processing apparatus includes segmenting means (11) for segmenting the entered coded stream with respect to a predetermined time unit, first forming means (23) for forming a time unit map indicative of an address of data every time unit of the coded stream which is segmented by the segmenting means (11) and second forming means (16) for forming an entry point map indicative of an entry point of said coded stream.

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.
