Abstract
Abstract Method of recording and reproducing picture information and a recording medium on which the picture information is recorded by the method, and an apparatus for playing such a recording medium. In addition to video format signal and a coded information signal, graphic codes including picture information and instruction codes representing a mixing ratio on each position of a two-dimensional picture formed by the video format signal are recorded on the recording medium after being inserted as a subcode of the coded information signal. At the time of reproduction, signals according to the graphic codes are mixed at each position of the video format signal in accordance with the instruction codes. Preferably, the graphic codes are preferably codes representing the color of each position of the two-dimensional picture, and the instruction codes are codes respectively representing mixing ratios previously determined in accordance with colors represented by the graphics codes.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
129 words
A method of recording and reproducing picture information on a recording medium comprising the steps of: recording, with a video format signal and a coded information signal, graphic codes including picture information and instruction codes respectively indicative of a mixing ratio between a picture according to said video format signal and a picture according to said picture information by said graphic codes at each position of a two-dimensional picture formed by said video format signal, by inserting said graphic codes and said instruction codes in a subcode of said coded information signal, on said recording medium; and mixing, at a time of reproduction from said recording medium, signals based on said graphic codes at each position of said video format signal in accordance with contents of said instruction codes.
Claim 2
Independent Claim
129 words
A method of recording and reproducing picture information on a recording medium comprising the steps of: recording, with a video format signal and a coded information signal, graphic codes including picture information and instruction codes respectively indicative of a mixing ratio between a picture according to said video format signal and a picture according to said picture information by said graphic codes at each position of a two-dimensional picture formed by said video format signal, by inserting said graphic codes and said instruction codes in a subcode of said coded information signal, on said recording medium; and mixing, at a time of reproduction from said recording medium, signals based on said graphic codes at each position of said video format signal in accordance with contents of said instruction codes.
Claim 3
Dependent Claim
44 words
A method as set forth in claim 1, wherein said graphic codes represent the color of each position of said two-dimensional picture, and said instruction codes respectively represent one of mixing ratios which are previously determined correspondingly to colors represented by said graphic codes.
Claim 4
Independent Claim
235 words
An apparatus for playing a picture information recording medium on which are recorded, in addition to a video format signal and a coded information signal, graphic codes including picture information and instruction codes respectively indicative of a mixing ratio between a picture according to said video format signal and a picture according to said picture information by said graphic codes at each position of a two-dimensional picture formed by said video format signal, said graphic codes and said instruction codes being inserted in a subcode of said coded information signal, said apparatus comprising: a pickup means for reading signals recorded on said recording medium and generating a pickup output signal; a video format signal demodulating means for demodulating said video format signal from said pickup output signal; a coded information signal demodulating means for demodulating said coded information signal from said pickup output signal; a graphic codes demodulating means for demodulating said graphic codes from an output signal of said coded information signal demodulating means; an instruction codes demodulating means for demodulating said instruction codes from said output signal of said coded information signal demodulating means; a means for generating signals based on said graphic codes from an output signal of said graphic codes demodulating means; and a mixing means for mixing said signals based on said graphic codes at each position of said video format signal in accordance with contents of said instruction codes.
Claim 5
Independent Claim
235 words
An apparatus for playing a picture information recording medium on which are recorded, in addition to a video format signal and a coded information signal, graphic codes including picture information and instruction codes respectively indicative of a mixing ratio between a picture according to said video format signal and a picture according to said picture information by said graphic codes at each position of a two-dimensional picture formed by said video format signal, said graphic codes and said instruction codes being inserted in a subcode of said coded information signal, said apparatus comprising: a pickup means for reading signals recorded on said recording medium and generating a pickup output signal; a video format signal demodulating means for demodulating said video format signal from said pickup output signal; a coded information signal demodulating means for demodulating said coded information signal from said pickup output signal; a graphic codes demodulating means for demodulating said graphic codes from an output signal of said coded information signal demodulating means; an instruction codes demodulating means for demodulating said instruction codes from said output signal of said coded information signal demodulating means; a means for generating signals based on said graphic codes from an output signal of said graphic codes demodulating means; and a mixing means for mixing said signals based on said graphic codes at each position of said video format signal in accordance with contents of said instruction codes.
