Abstract

PURPOSE: To obtain easily a good-resolution picture by dividing luminance signals, which correspond to a static picture, and color signals or luminance color composite signals in respect to time and transmitting them.
CONSTITUTION: In picture transmission unit 9, luminance signal Y and color signal C which constitute a static picture are transmitted frame by frame in the time division system as they are separted from each other. For example, the transmissin is performed by inserting the luminance signal of static picture D2, which is transmitted to receiving terminal 2, and the corresponding color signal to frames D2Y and D2C respectively. Similarly, the transmission is performed by inserting the luminance signal of the static picture E6, which is transmitted to terminal 6, and the corresponding color signal to frames E6Y and E6C respectively. Buffer memory 2 receives signals D2Y and D2C at the timing of figure (b) and records them. Similarly, memory 6 receives signals at the timing of figure (c) and records them. After recording memory 2 reads out signals D2Y and D2C simultaneously to display static picture D2, and terminal 6 displays static picture E6, so that good-resolution static pictures can be obtained.
