Abstract: Stream recording assumes e.g. a settop box to be connected to a DVD Streamer. The connection is e.g. of IEEE 1394 type using interfaces including transmitting and receiving firmware. Stream Data include one or more Stream Objects which each can be stored as a Program Stream as described in ISO/IEC 13818-1, Systems. The invention allows to realise Access Units in such DVD Streamer. Each Stream Object contains its own Access Unit data. A trickplay mode, e.g. fast forward, is performed by selecting the desired Access Units which are derived from a mapping list with incremental application packet arrival times.

Abstract: The moving picture reproducing device to decode frames of moving picture data and synchronously output decoded moving picture data based on time information given to each frame, and to count up the number of frames from a first frame up to a second frame. The first frame is given the time information and appears first toward the positive direction of time axis from a predetermined intermediate seek position in the data stream. The second frame appears first after a key frame which is not given the time information and appears first toward the positive direction of time axis from the intermediate seek position. The time information of the key frame is thereby interpolated based on the time information of the first frame and the counted number of frames to reduce the extent of decoding processing and buffering during reproducing a MPEG moving picture data stream when the reproducing is performed from an optional intermediate seek position.

Abstract: A digital broadcast signal of a channel received in a tuner is converted into digital data by a digital demodulation section. Based on the digital data, a CPU detects the partial of the corresponding subchannel from the whole transport stream (TS) of the digital data and causes a system controller to extract digital data of the subchannel and record the digital data on a hard disk in a predetermined format.

Abstract: A table which includes entries corresponding to frames in one-to-one relationship is generated. Information of each frame is described in each entry according to a display order. When video data has a frame rate of 24 frames/sec, a dummy entry is inserted for every four frames. A top_field_first flag, a repeat_first_field flag, and a picture type flag are described in each entry. A frame to be displayed is generated based on these flags. The present invention can be applied to an optical disc apparatus.

Abstract: The present invention has an objective of providing an optical disk having a high resolution picture and a system for reproducing data on the optical disk, which are compatible with a conventional system for reproducing an ordinary resolution picture. A high resolution signal is divided into a main signal and a sub signal by picture division means and MPEG-encoded. The main signal and the sub signal are divided into frames each having 1 GOP or more. The resultant first interleave block 54 and second interleave block 55 are recorded alternately on an optical disk. A high resolution reproduction apparatus reproduced both the first and second interleave blocks, so that a high resolution picture is obtained. A non-high resolution reproduction apparatus reproduces only the first or second interleave block, so that an ordinary resolution picture.
