    DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a disk in which additional information for a slide show according to the present invention is recorded, an apparatus for performing the same, and a preferred embodiment of the method will be described with reference to the accompanying drawings.
    Two streams are required to implement the slide show. One of the two streams is an audio stream and the other is a video stream in which video data for a slide show is multiplexed. Each stream is separately stored in pack units, an audio stream is stored in an audio pack, and a video stream for a slide show is stored in a video pack. When the slide show is played using these two streams, the video stream is decoded while the audio stream is played in pack units, and the slide show is performed in accordance with the time information included in each stream.
    Here, in the general audio pack structure, as shown in FIG. 1, audio data is configured in units of frames, and one frame has audio data having a predetermined number of samples. In one audio pack, there is one audio packet except for a special case. Therefore, since only one packet exists in one pack, different types of packs exist when two streams exist.
    On the other hand, since the audio data stream and the video data stream in which the video data for the slide show are multiplexed are different in packs, the decoder or player demultiplexes the pack for each stream, and thus the time in each pack header. The information must be reproduced in timing using both the information and the time information contained in the packet header in the pack. In this case, since two streams are used, timing must be adjusted using four time information.
    Therefore, in order to implement a slide show with the pack structure shown in FIG. 1, timing control is performed using four time information in two streams. Therefore, a complicated circuit is required according to the timing control. Timing control is difficult.
    In addition, it is difficult to record and play back two streams in real time because the two streams for a single event called a slide show are recorded and played separately.
    In addition, since two types of packs need to be aligned on a pack-by-pack basis, stuffing data for filling gaps is used more frequently than when a single pack is processed, thereby reducing storage space efficiency.
    Therefore, the new pack structure recorded on the disc proposed by the present invention is shown in FIG. 2, and is different from the general pack structure shown in FIG. 1. The proposed structure can be composed of two or more kinds of packets for two streams in one pack, that is, a pack of multiplexed audio and video packets, and each packet has a different stream identifier (hereinafter, referred to as ID). have. The audio packet in one pack stores audio data of one or several frames, and the video packet stores video data of one or several frames having a predetermined relationship with the audio packet. That is, a packet of audio and video may be multiplexed in one pack. For example, a pack header, a packet header for audio and audio data in audio frame units, a packet header for video and video data in image frame units, A packet header for audio and audio data in audio frame units are recorded, and audio data in image frame units and subsequent video data in frame units have a predetermined relationship. The predetermined relationship may be production information for explaining the content of the audio, which is the main data recorded on the disc, information on the recorded content, information on the composer, the singer, and the performer as mentioned above. In addition, the number of frames may be one or several, and the number of audio frames and the number of video frames may be the same or different.
    If the packet continues to be stored in one pack and there is not enough space to record video data in the i-th pack as shown in FIG. 2, the video packet header is inserted again in the next i + 1 th pack. After recording the video data, audio packets are recorded again.
    In the case of playback using the pack structure shown in FIG. 2, audio data in audio frame units is accessed and reproduced based on audio packets, and since video data is located immediately after audio data in image frame units, it is directly accessed without a special access operation. Since it can be reproduced by the data, there is no need for a separate process for synchronization in time by the position of the data.
    When the pack structure proposed by the present invention is used, the encoder of the optical recording / reproducing apparatus performs streaming as shown in FIG. 3, and the decoder performs streaming as shown in FIG.
    Referring to FIG. 3, streaming performed by an encoder is described. Audio data processed in audio frame units and video data in image frame units for a slide show are input to the first and second packet header inserters 110 and 120.
    The first packet header inserter 110 and the second packet header inserter 120 insert the packet headers using the stream ID for each data to pack the first packet data and the second packet data processed in packet units. To the header inserter 130. The pack header inserter 130 multiplexes audio packets and video packets in pack units as in the pack structure shown in FIG. 2 to generate and transmit data in pack units.
    Meanwhile, referring to FIG. 4, the streaming performed by the decoder will be described. After the pack header remover 210 removes the pack header from the input pack data, the pack header remover pack demultiplexer 220 removes the pack header data. Is applied.
    The demultiplexer 220 detects the packet header from the pack unit data from which the pack header is removed, checks the stream ID in the detected packet header, and outputs an audio data packet (data in the first packet unit) and video data according to each stream ID. The output is divided into packets (data of a second packet unit).
    The first depacketizer 230 removes the packet header from the audio data packet to output audio data in audio frame units, and the second depacketizer 240 removes the packet header from the video data packet to perform video frame unit Output video data. Here, the first and second depacketizers 230 and 240 may be configured as a kind of buffer.
    Accordingly, the present invention reproduces video data in units of image frames applied from the second depacketizer 240 while reproducing audio data in units of audio frames applied from the first depacketizer 230.
    As described above, since the present invention multiplexes and stores the audio data packet and the video data packet in one pack, the audio data in the audio frame unit is accessed and reproduced based on the audio data packet, and the video data in the image frame unit is audio. Located directly behind the data, it can be reproduced without special timing control, making it simple to implement, real-time recording and playback, and efficient storage of packs.
