Abstract
Abstract Method and apparatus for recording and reproducing picture information on a recording medium. In addition to a coded information signal, subcodes together with identification codes for identifying the coding system of the subcodes are recorded in a first recording area of a recording medium and the identification codes and content discrimination codes for indicating contents of information included in the subcode using the coding system indicated by the identification code are recorded in a second recording area of the recording medium. It is further characterized that the identification code and the content discrimination information recorded in the second recording area are displayed at the time of the playback of the recording medium.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
75 words
A method of recording information comprising the steps of: recording, in addition to a coded information signal, subcodes together with identification codes for identifying the coding system of said subcodes, in a first recording area of a recording medium; and recording said identification codes and content discrimination codes for indicating contents of information included in the subcode using the coding system indicated by said identification code, in a second recording area of said recording medium.
Claim 2
Independent Claim
75 words
A method of recording information comprising the steps of: recording, in addition to a coded information signal, subcodes together with identification codes for identifying the coding system of said subcodes, in a first recording area of a recording medium; and recording said identification codes and content discrimination codes for indicating contents of information included in the subcode using the coding system indicated by said identification code, in a second recording area of said recording medium.
Claim 3
Dependent Claim
99 words
A recording and reproducing method comprising the steps of: recording, in addition to a coded information signal, subcodes together with identification codes for identifying the coding system of said subcodes, in a first recording area of a recording medium; recording said identification codes and content discrimination codes for indicating contents of information included in the subcode using the coding system indicated by said identification code, in a second recording area of said recording medium; and at the time of playback of said recording medium, displaying said identification code and said content discrimination information recorded in said second recording area.
Claim 4
Dependent Claim
99 words
A recording and reproducing method comprising the steps of: recording, in addition to a coded information signal, subcodes together with identification codes for identifying the coding system of said subcodes, in a first recording area of a recording medium; recording said identification codes and content discrimination codes for indicating contents of information included in the subcode using the coding system indicated by said identification code, in a second recording area of said recording medium; and at the time of playback of said recording medium, displaying said identification code and said content discrimination information recorded in said second recording area.
Claim 5
Independent Claim
188 words
An apparatus for playing a picture information recording medium having a first recording area in which subcodes together with identification codes for identifying the coding system of said subcodes are recorded in addition to a coded information signal and a second area in which said identification codes and content discrimination codes for indicating contents of information included in the subcode using the coding system indicated by said identification code are recorded, said apparatus comprising: a pickup means for reading signals recorded on said recording medium and generating a pickup output signal; a coded information signal demodulating means for demodulating said coded information signal from said pickup output signal; a character codes demodulating means for detecting the coding system using said identification code contained in an output signal of said coded information signal demodulating means, and for demodulating codes representing characters indicating the detected coding system and codes representing characters indicating contents of the recorded information, corresponding to said content discrimination information; and a video signal generating means for generating a video signal corresponding to designated characters, in response to an output signal of said character code demodulating means.
Claim 6
Independent Claim
188 words
An apparatus for playing a picture information recording medium having a first recording area in which subcodes together with identification codes for identifying the coding system of said subcodes are recorded in addition to a coded information signal and a second area in which said identification codes and content discrimination codes for indicating contents of information included in the subcode using the coding system indicated by said identification code are recorded, said apparatus comprising: a pickup means for reading signals recorded on said recording medium and generating a pickup output signal; a coded information signal demodulating means for demodulating said coded information signal from said pickup output signal; a character codes demodulating means for detecting the coding system using said identification code contained in an output signal of said coded information signal demodulating means, and for demodulating codes representing characters indicating the detected coding system and codes representing characters indicating contents of the recorded information, corresponding to said content discrimination information; and a video signal generating means for generating a video signal corresponding to designated characters, in response to an output signal of said character code demodulating means.
Claim 7
Dependent Claim
65 words
A recording medium having a first recording area in which subcodes together with identification codes for identifying the coding system of said subcodes are recorded in addition to a coded information signal and a second area in which said identification codes and content discrimination codes for indicating contents of information included in the subcode using the coding system indicated by said identification code are recorded.
Claim 8
Dependent Claim
65 words
A recording medium having a first recording area in which subcodes together with identification codes for identifying the coding system of said subcodes are recorded in addition to a coded information signal and a second area in which said identification codes and content discrimination codes for indicating contents of information included in the subcode using the coding system indicated by said identification code are recorded.
