Abstract
Abstract A header for controlling each data block is disposed at the beginning of a data unit composed of a combination of video data, sound data, and sub-picture data. Header data is disposed at the beginning of each data block to control data in the data block. Thus, in particular, when a plurality of channels of data and a plurality of streams of data are recorded in a data block and one of them is selected, each channel data and each stream data can be properly controlled. <IMAGE>

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
99 words
A recording medium on which a data unit is recorded, the data unit having a plurality of types of data blocks, the data unit comprising: a unit header disposed at the beginning of the data unit and adapted for controlling each of the data blocks as independent data of the data unit; and a block header disposed at the beginning of each of the data blocks and adapted for controlling data of the data block, characterised in that the unit header further includes search information that represents a start address of another data unit spaced apart therefrom by ±n.
Claim 2
Dependent Claim
20 words
The medium as set forth in claim 1, wherein the header of the data unit further includes identification information thereof.
Claim 3
Dependent Claim
35 words
The medium as set forth in claim 1, wherein the header of the data unit further includes a program number that represents a program of the predetermined data unit in a set of data unit.
Claim 4
Independent Claim
99 words
An apparatus for reproducing a recording medium in which a data unit is recorded, the data unit having a plurality of types of data blocks and a header at the beginning of the data unit, and the header including search information that represents a start address of another data unit spaced apart therefrom by ±n, the apparatus comprising means for reading out data on the medium, characterised in that the apparatus further comprises extracting means for extracting the search information from the read data; and means for performing a high speed searching operation corresponding to the extracted search information.
