Abstract
An optical disc apparatus capable of time search function and a time search playback method thereof are disclosed, wherein the method comprises: searching for a playback area corresponding to a particular time using C_PBIT (Cell Playback Information Table) and VTS_VOBU_ADMAP (Video Title Set Video Object Unit Address Map) included in navigation information of an optical disc; and performing a playback operation from the searched playback area.
Claims16
A time search playback method of an optical disc apparatus, the method comprising:
- searching for a playback area corresponding to a particular time using a C_PBIT (Cell Playback Information Table) and a VTS_VOBU_ADMAP (Video Title Set Video Object Unit Address Map) included in navigation information of an optical disc;
- and
- performing a playback operation from the searched playback area,
- wherein the search step comprises:
- detecting a cell corresponding to the particular time by using the C_PBIT, and
- detecting a start address of a Video Object Unit corresponding to the particular time out of Video Object Units contained in the cell thus detected, using the VTS_VOBU_ADMAP, and an area corresponding to the detected start address of the Video Object Unit is searched as the playback area, and
- wherein the cell corresponding to the particular time is detected by sequentially adding cell playback time contained in the Cell Playback Information Table according to a cell playback order.
An optical disc apparatus comprising:
- an optical pick-up configured to read out data recorded in an optical disc;
- a playback processor configured to play back the data read out from the optical pick-up and to output the same;
- a playback area search unit configured to search for a playback area corresponding to a particular time by using cell playback time contained in a cell playback information table, the cell playback time being sequentially added according to a cell playback order for a cell corresponding to the particular time, and by using a Video Title Set Video Object Unit Address Map, the cell playback information table and the Video Title Set Video Object Unit Address Map being contained in navigation information read out from the optical disc;
- and
- a microcomputer configured to control the optical pick-up and the playback processor so that the playback operation can be performed from the searched playback area.
A time search playback method of an optical disc apparatus, the method comprising:
- searching for a playback area corresponding to a particular time by sequentially adding cell playback time contained in a C_PBIT (Cell Playback Information Table) according to a cell playback order for a cell corresponding to the particular time and by using a VTS_VOBU_ADMAP (Video Title Set Video Object Unit Address Map), the C_PBIT and the VTS— VOBU_ADMAP being included in navigation information of an optical disc;
- and
- performing a playback operation from the searched playback area.
