Abstract

Abstract A reproducing apparatus is disclosed wherein reproduction advancement data are produced using data, which are recorded in a user TOC area of a recording medium (1) as access information upon recording and/or reproduction of data, to allow ordinary and special reproducing operations in the forward direction and the reverse direction readily. The reproduction advancement data are produced based on user TOC information such that segment numbers are indicated in order of numbers of programs to be reproduced or in predetermined order of reproduction. Upon reproduction, a reproduction pointer is advanced or retreated on the reproduction advancement data to discriminate a segment so that the segments can be accessed successively in the forward or reverse reproducing direction.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 231 words
A reproducing apparatus for reproducing a program from a recording medium (1) which has recorded thereon, as segment management data which are used to reproduce unit program data each recorded on a single continuous segment or a plurality of discrete segments, for each of the recorded programs, management data including a plurality of part tables each having a start address and an end address of a segment and link information indicative of another part table in which a start address and an end address of another segment to be linked to the end address of the former segment are stored and corresponding table indicating data indicating a stored position of one or a head one of a plurality of ones of the part tables of the management data for each of the recorded programs, comprising: data read-out means (3, 7) for reading out data from the recording medium (1); means (8) for producing reproduction advancement data from the segment management data read out by said data read-out means; control means (11, 12) for controlling an ordinary reproducing oration or a irregular reproducing operation based on the reproduction advancement data; and storage means (13) for storing the reproduction advancement data therein; the reproduction advancement data being produced such that segment numbers are indicated in order of reproduction so that the segments can be accessed successively in the forward or reverse reproducing direction.
Claim 2
Dependent Claim 53 words
A reproducing apparatus according to claim 1, wherein the reproduction advancement data are produced such that start addresses and end addresses of the segments are indicated in order of reproduction so that the the segments can be accessed successively in the forward or reverse reproducing direction without referring to the segment management data.
Claim 3
Dependent Claim 65 words
A reproducing apparatus according to claim 1, wherein the reproduction advancement data are produced such that segment numbers and/or start addresses and end addresses of the segments are indicated in order of reproduction and the numbers of programs to which the segments belong are indicated so that the segments can be accessed successively in desired order of programs in the forward or reverse reproducing direction.
Claim 4
Dependent Claim 72 words
A reproducing apparatus according to any of claims 1 to 3, wherein said storage means (13) stores the reproduction advancement data in a sequence table area thereof, and said control means (11, 12) reads out a segment number in response to a reproduction pointer, which moves on the sequence table stored in said storage means (13), and reproduces a program of a segment in accordance with the segment number thus read out.
Claim 5
Dependent Claim 16 words
A reproducing apparatus according to claim 4, wherein the sequence table is produced upon reproducing operation.
