Abstract: PURPOSE: A method for selecting audio channels is provided to trace an input of audio selection by a user, though a program or an audio data stream is switched in an A/V(Audio-Visual) apparatus that regenerates a plurality of audio streams, so as to select a same type of audio channels. CONSTITUTION: A plurality of programs are included. One program includes at least two types audio data streams. Each audio data stream includes at least two sub audio data streams having a series of not-duplicated ID codes according to a predetermined priority. If a program is switched to another program, whether a sub audio data stream having a channel ID code identical to a channel ID code allocated to a sub audio data stream of the program before switching exists in the switched program is searched. If so, the sub audio data stream having the identical channel ID code is selected in the switched program. And if not, a sub audio data stream having a highest priority of channel ID code is selected in another program.

Abstract: PURPOSE: An apparatus for performing a simultaneous recording or a simultaneous playing relating to many digital A/V(Audio/Video) programs is provided to bind more than two A/V signals as one A/V signal to encode or record the A/V signal, and to divide the encoded or recorded A/V signal into many independent channels, so as to play the A/V signal according to a user selection. CONSTITUTION: Signal input terminals(20,21,22,23) input many A/V(Audio/Video) signals selected by a user's operation. A signal stream controller(24) performs a down-sampling relating to the video signals only, and performs a selective down-mixing or a specific channel deleting relating to the audio signals only. An encoder(25) synthesizes the processed A/V signals of the signal stream controller(24) into one A/V signal, and compresses the A/V signal. Recorded media(26) record an encoding signal outputted from the encoder(25). The recorded media(26) record simultaneous recording additional information for recording. The signal stream controller(24) diminishes the size of frames by N to 1 ratio, relating to the video signals, and combines the diminished frames to make one frame.

Abstract: PURPOSE: A recording medium, a method for automatically generating scene turning point information and device for recording/playing back the information are provided to effectively generate the information and not to increase the charge of a hardware by monitoring a characteristic change of a video frame and automatically generating the information according to the change of characteristics. CONSTITUTION: A video sequence of a serial frame unit is inputted to a DCT(Discrete cosine transform) processing unit via a frame buffer(700). The DCT processing unit(710) performs a DCT by dividing the video data to blocks of 8X8 size. A mosaic activity processing unit(720) generates a mosaic activity adapting a statistical variance of energy values in zero frequency band. The zero frequency band is a mean brightness value of each DCT block. The entire activity processing unit(720) generates an entire activity by measuring an amount of frequency energy inside every DCT block and summing the amounts. A scene turning point generating unit(740) generates scene turning point information by discriminating a corresponding frame as a "type-1 frame" or a "type-2 frame" based on the mosaic activity and the entire activity. A navigation data generating unit(750) contains the scene turning point information in navigation data by converting to a pointer.

Abstract: PURPOSE: A method for generating additional information is provided to secure continuous reproduction between data streams after recording plural data streams of packet data type in a recording medium. CONSTITUTION: SOBI(stream object information) includes a continuous playback information and a continuous time control information. The continuous playback information contains a value representing a seamless playback or a seamy playback. And, the continuous time control information includes a reference time, an offset, and a gap length. When the continuous playback information represents the seamless playback, the continuous time control information is effective. Herein, the continuous time control information represents the precise output time of an SOB2 ensuring the seamless playback at the boundary of an SOB1 and the SOB2. The continuous time control information uses the reference time or the offset between an ATS(arrival time stamp) corresponding to the reference time and an original ATS. The continuous time control information uses the gap length resetting a counter after outputting the last packet of the SOB1 as the arrival time of the first packet in the SOB2.

Abstract translation: 目的：提供用于产生附加信息的方法，用于在记录介质中记录分组数据类型的多个数据流之后，确保数据流之间的连续再现。 构成：SOBI（流对象信息）包括连续重放信息和连续时间控制信息。 连续重放信息包含表示无缝播放或连续播放的值。 并且，连续时间控制信息包括基准时间，偏移量和间隙长度。 当连续重放信息表示无缝重放时，连续时间控制信息是有效的。 这里，连续时间控制信息表示确保在SOB1和SOB2的边界处的无缝重放的SOB2的精确输出时间。 连续时间控制信息使用与参考时间相应的ATS（到达时间戳）与原始ATS之间的参考时间或偏移。 连续时间控制信息使用输出SOB1的最后一个分组之后的计数器的间隙长度作为第一分组在SOB2中的到达时间。
