Abstract
PURPOSE:To enable to transmit the picture and audio in high quality in the same band as television signal transmission system, by playing back the signal of one field of picture signal continously for the 2 fields. CONSTITUTION:Only one field A1 among one frame of input continuous picture signal, is transmitted, and transmission is made by inserting the audio a' in which the audio (a) for one frame's share is compressed for the time axis in the period of the field A2 not transmitted. In this case, at the V blanking period of the field to be transmitted, the identifying code of picture signal is added. When the picture signal identifying code is discriminated from the transmitted input signal, one field's share is taken into the picture memory, it is operated as the field memory for the next field period to play back the same signal A1. Further, the audio signal a' transmitted at the next field, is extended at one frame period and played back as the original audio signal (a). Thus, the audio is obtained as continuous signal, and the picture signal also can be obtained as a continuous signal in which one field signal is repeated for two fields.
