Video data transmitting system

DETAILED DESCRIPTION It is an object of the present invention to solve the problems mentioned above.
Another object of the invention is to provide a data transmitting system which can transmit a good image and can easily perform the needed signal processing on the receiving side in an apparatus which compresses data by means of a block encoding.
To accomplish such objects, according to the present invention, as one embodiment, there is disclosed a video data transmitting system comprising: (a) first block encoding means for encoding a luminance signal on a unit basis of an encoding block consisting of a plurality of pixels; (b) second block encoding means for encoding a chrominance signal on a unit basis of an encoding block consisting of a plurality of pixels, a ratio of a sampling frequency of the luminance signal and a sampling frequency of the chrominance signal being set to the ratio n:m (n and m are positive integers and m<n); (c) time sharingly multiplexing means for time sharingly multiplexing the encoded luminance signal encoded by the first block encoding means and the encoded chrominance signal encoded by the second block encoding means; (d) sync signal adding means for adding a sync signal to the signal time sharingly multiplexed by the time sharingly multiplexing means and for forming a sync block, the sync block including the encoded luminance signals of n encoding blocks, the encoded chrominance signals of m encoding blocks, and one continuous sync signal train; and (e) transmitting means for transmitting the signal to which the sync signal was added by the sync signal adding means.
The above and other objects and features of the present invention will become apparent from the following detailed description with reference to the accompanying drawings.
