Abstract
Abstract The invention provides a disc playing apparatus which enables the reproduction speed of subcode information to be set at a designated speed. The subcode read-out by a reading device (3) is decoded by a decoding device (31) and each piece of digital data successively output from the decoding device (31) is transmitted at a predetermined transmission rate. The interval between pieces of the digital data is varied in response to a designated reproduction speed, and at the same time each piece of the digital data is transmitted at the predetermined rate.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
96 words
A disc playing apparatus for playing a disc on which a digital data which is to be transmitted at a predetermined transmission rate is recorded as a subcode, in addition to a coded information signal, the apparatus comprising: a reading means for reading said coded information signal and said subcode from said disc; a decoding means for decoding said subcode read-out by said reading means and producing a digital data; and a signal transmission means repeating means for transmitting each piece of said digital data successively output from said decoding means at said predetermined transmission rate.
Claim 2
Dependent Claim
96 words
A disc playing apparatus for playing a disc on which a digital data which is to be transmitted at a predetermined transmission rate is recorded as a subcode, in addition to a coded information signal, the apparatus comprising: a reading means for reading said coded information signal and said subcode from said disc; a decoding means for decoding said subcode read-out by said reading means and producing a digital data; and a signal transmission means repeating means for transmitting each piece of said digital data successively output from said decoding means at said predetermined transmission rate.
Claim 3
Dependent Claim
122 words
An apparatus as claimed in claim 1, wherein said signal transmission means comprises: an interval detection means for detecting the interval between pieces of said digital data successively output from said decoding means and producing an interval data representing said interval; a memory means for storing said digital data supplied from said decoding means; a memory control means for successively writing said digital data output from said decoding means and in turn reading-out said digital data written in same memory means at intervals obtained by adjusting the interval represented by said interval data in response to a designated reproduction speed; and a means for transmitting said digital data read-out from said memory means successively by one bit at said predetermined transmission rate.
Claim 4
Dependent Claim
50 words
An apparatus as claimed in claim 2, further comprising a play control means for jumping an information reading point of said reading means by a predetermined number of track spacings each time when a difference between writing and reading addresses of said memory means becomes larger than a predetermined value.
