Abstract:
A video signal recording apparatus for digitally recording on a storage medium a video signal comprising an image signal, an audio signal, at least one video-associated information signal, and at least one audio-associated information signal, wherein said video-associated information signals and said audio-associated information signals are included in a vertical blanking period of said video signal and wherein said storage medium includes a first recording area, a second recording area, and a third recording area, said apparatus comprising:image encoding means for encoding said image signal to produce a coded image signal;audio encoding means for encoding said audio signal to produce a coded audio signal;collection means for collecting said video-associated information and said audio-associated information, for formatting said video-associated information to produce a multiple of video-associated information packs and for formatting said audio-associated information to produce a multiple of audio-associated information packs, said video-associated information packs being formatted so as to include all of said video-associated information signals that are below a predetermined frequency; andrecording means for digitally recording said coded image signal in said first recording area, for digitally recording said coded audio signal in said second recording area, and for digitally recording said video-associated information packs and said audio-associated information packs in said third recording area, said recording being performed such that said video-associated information signals that are below said predetermined frequency and included in said video-associated information packs are recorded transparently;wherein said third recording area is comprised of a video-associated information main area for storing video-associated information which is discernable by all systems capable of receiving said video signal, and a video-associated information optional area for storing video-associated information which is discernable only by selected systems capable of receiving said video signal;wherein the video-associated information stored in said video-associated information main area includes a plurality of different types of vertical blanking interval information and an indication of an aspect ratio of said image signal is included in each type of vertical blanking interval information; andwherein said packs containing said video-associated information signals that are below said predetermined frequency are recorded in said video-associated information main area.
