Apparatus for reproducing and processing picture information including graphic codes from a recording medium

Claim 1

An apparatus for reproducing and processing picture information for forming a picture signal corresponding to a graphic code obtained from a recording medium on which, in addition to a video format signal and a coded information signal, graphic codes including picture information are recorded, said graphic codes being inserted as a subcode of said coded information signal, and for mixing said picture signal in said video format signal obtained from said recording medium, said apparatus comprising: a first input means for receiving said subcode obtained from said coded information signal recovered rom said recording medium; a second input means for receiving said video format signal recovered from said recording medium; a demodulation means for demodulating said graphic codes from said subcode supplied from said first input means; a picture signal generating means for generating said picture signal from said graphic codes demodulated at said demodulation means; a mixing means for mixing said picture signal generated at said picture signal generating means with said video format signal supplied through said second input means; an operation means for generating a display mode changing command by a manual operation; and a display mode changing means connected to said operation means and at least one of said picture signal generating means and said mixing means, for changing a mode of display of said picture signal within a picture formed by said video format signal in response to said display mode changing command.

Claim 2

An apparatus for reproducing and processing picture information for forming a picture signal corresponding to a graphic code obtained from a recording medium on which, in addition to a video format signal and a coded information signal, graphic codes including picture information are recorded, said graphic codes being inserted as a subcode of said coded information signal, and for mixing said picture signal in said video format signal obtained from said recording medium, said apparatus comprising: a first input means for receiving said subcode obtained from said coded information signal recovered rom said recording medium; a second input means for receiving said video format signal recovered from said recording medium; a demodulation means for demodulating said graphic codes from said subcode supplied from said first input means; a picture signal generating means for generating said picture signal from said graphic codes demodulated at said demodulation means; a mixing means for mixing said picture signal generated at said picture signal generating means with said video format signal supplied through said second input means; an operation means for generating a display mode changing command by a manual operation; and a display mode changing means connected to said operation means and at least one of said picture signal generating means and said mixing means, for changing a mode of display of said picture signal within a picture formed by said video format signal in response to said display mode changing command.

Claim 6

An apparatus for reproducing and processing picture information for forming a picture signal corresponding to a subcode obtained from a recording medium on which, in addition to a coded information signal, graphic codes including picture information occupying N (N being a natural number equal to or greater than 2) channels are recorded, said graphic codes being inserted as the subcode of said coded information signal, said apparatus comprising: an input means for receiving said subcode obtained from said coded information signal recovered from said recording medium; N memories; a demodulation means for demodulating said graphic codes from said subcode supplied from said input means; a memory control means for performing control operations of writing said graphic codes occupying each of said N channels in said N memories respectively, and reading-out stored contents of one of said N memories in accordance with a switch command responsive to a selection of said channel of said picture information a picture signal generating means for generating said picture signal from a graphic code read-out from one of said N memories by said memory control means.

Claim 7

An apparatus for reproducing and processing picture information for forming a picture signal corresponding to a subcode obtained from a recording medium on which, in addition to a coded information signal, graphic codes including picture information occupying N (N being a natural number equal to or greater than 2) channels are recorded, said graphic codes being inserted as the subcode of said coded information signal, said apparatus comprising: an input means for receiving said subcode obtained from said coded information signal recovered from said recording medium; N memories; a demodulation means for demodulating said graphic codes from said subcode supplied from said input means; a memory control means for performing control operations of writing said graphic codes occupying each of said N channels in said N memories respectively, and reading-out stored contents of one of said N memories in accordance with a switch command responsive to a selection of said channel of said picture information a picture signal generating means for generating said picture signal from a graphic code read-out from one of said N memories by said memory control means.
