ABSTRACT:
Methods and apparatus are provided for recording video signals in a plurality of tracks on a recording medium. In certain embodiments, first and second video signal intervals include respective first and second common sub-area signals representing at least one common sub-area of a video screen. The common sub-area signals of the first and second video signal intervals are recorded at respectively different locations within the plurality of tracks. In certain embodiments, component color video signals including luminance signals and first and second color difference signals are divided into a plurality of discrete cosine transformation (DCT) blocks and blocks representing common respective subdivisions of a video screen are assembled into corresponding macro blocks. Adjacent macro blocks are assembled into super macro blocks which, in turn, are arranged in a shuffled sequence relative to the positions of their subdivisions on the video screen for recording in the shuffled sequence. In certain embodiments, digital video signals representing a video screen are recorded in a plurality of tracks on a recording medium after dividing the digital video signals into a plurality of macro blocks assembled into sub-area groups of the video screen. The sub-area groups are shuffled by forming a sequence of track units each including a plurality of the sub-area groups one each from a respective horizontal division of the video screen. Each track unit is recorded in a respective one of a plurality tracks on the recording medium.
