Recording medium and signal processing apparatus
View Patent ↗A recording medium has a first area storing an audio title set. The audio title set contains a plurality of audio objects including a first audio object and a second audio object. The first audio object consists of first packs having audio data. The second audio object includes second packs having audio data and a third pack having real-time information related to the audio data in the second packs. The recording medium has a second area storing a still-picture set. The still-picture set includes a fourth pack having still-picture data related to the audio data in the first packs and the audio data in the second packs.
1. An audio signal encoding apparatus comprising:
first means for converting an analog audio signal into corresponding audio data of a digital form; and
second means for generating second data of a data structure in response to the audio data generated by the first means;
wherein the data structure comprises:
an audio title set (ATS) including audio packs containing audio data; and
a still-picture set (SPS) including a still-picture pack containing still-picture data relating to the audio data;
the still-picture set (SPS) including still-picture object set (ASVOBS) having at least one still-picture unit (ASVU) and further including still-picture set information (ASVSI) having start address map (ASV-ADMAP) for still-picture data for respective still-picture unit (ASVU) for reproducing a still-picture unit (ASVU) basis;
the still-picture unit (ASVU) including at least one still-picture object (ASVOB), the still-picture object (ASVOB) having a still-picture pack; and
the audio title set (ATS) including audio title set information (ATSI) containing playback information (SPCIT) for playback control of the still-picture data in the still-picture set (SPS).
2. An apparatus for decoding a signal recorded on a recording medium comprising:
first means for decoding audio title set information (ATSI) into playback information (SPCIT) for playback control of still-picture data, the audio title set information (ATSI) being in an audio title set (ATS) recorded on the recording medium;
second means for decoding audio packs in the audio title set (ATS) recorded on the recording medium into audio data;
third means for decoding start address map (ASV-ADMAP) for still-picture data for a still-picture unit (ASVU) in still-picture set information (ASVSI), the still-picture set information (ASVSI) being in a still-picture set (SPS) recorded on the recording medium, and a still-picture object set (ASVOBS) being in the still-picture set (SPS) recorded on the recording medium into start address data for still-picture data and still-picture data, respectively; and
fourth means for controlling and outputting the still-picture data generated by the third means in response to the playback information (SPCIT) generated by the first means and the start address data for still-picture data generated by the third means.
3. A method of transmitting an audio signal, comprising the steps of:
converting an analog audio signal into corresponding audio data of a digital form;
generating second data of a data structure in response to the audio data;
packetizing the second data into a packet signal; and
transmitting the packet signal via a communication line;
wherein the data structure comprises:
an audio title set (ATS) including audio packs containing audio data; and
a still-picture stet (SPS) including a still-picture pack containing still-picture data relating to the audio data;
the still-picture set (SPS) including still-picture object set (ASVOBS) having at least one still-picture unit (ASVU) and further including still-picture set information (ASVSI) having start address map (ASV-ADMAP) for still-picture data for respective still-picture unit (ASVU) for reproducing a still-picture unit (ASVU) basis;
the still-picture unit (ASVU) including at least one still-picture object (ASVOB), the still-picture object (ASVOB) having a still-picture pack; and
the audio title set (ATS) including audio title set information (ATSI) containing playback information (SPCIT) for playback control of the still-picture data in the still-picture set (SPS).
