摘要： A vertical edge width calculation circuit 31 has a plurality of series-connected delay circuits 31a to 31h each having a one-horizontal period delay time. A horizontal edge width calculation circuit has a plurality of 1-pixel delay circuits 32a to 32h corresponding to the edge width. A horizontal distance between an input digital superimpose key signal and a raster position is calculated in accordance with the calculated vertical distance, that is, the edge width. In accordance with the calculated vertical and horizontal distances, a detection circuit 34 detects as a true Euclidean distance a minimum value among a plurality of Euclidean distances between the digital superimpose key signal and the raster position which are stored in ROMs 33.sub.0 to 33.sub.5.

摘要： The digital chromakey system filters out a color signal from a first digital color-television signal and produces a chromakey signal which is combined with the first digital color-television signal to cancel out the color portion. The chromakey signal is also combined with a second color-television signal so that the second color television signal can be inserted into the first color-television signal whose color portion was cancelled.

摘要： The code division multiplex transmission system according to the present invention produces data for transmission by, time-division multiplexing the signals for synchronizing spread code prepared for an easy synchronization of spread code on the receiving side and the information related to the structure or synchronization of each of a plurality of transmission data streams such as parameters information about the coding rate of the convolution code and interleaving size for each transmission data stream, generating spread frequency modulated signals of the above time-division multiplexed signals by a spread frequency modulation using a spread code known to the receiving side, and code-division multiplexing the resulting spread frequency modulated signals over the spread frequency modulated signals of the plurality of transmission data streams. As a result, the receiving terminal can obtain information such as parameters information of all the transmission data streams, as long as the receiving terminal receives the synchronization signal. Therefore, even if the receiving terminal does not understand the parameter values required for the reception of each transmission data stream, the receiving terminal can receive any transmission data stream easily and quickly, by setting the parameter values for each receiving process based on the parameters information about each transmission data stream obtained by the reception of the synchronization signal.
