Abstract

PURPOSE:To attain an accurate scanning line interpolation to all signals including a moving image and to improve vertical resolution by detecting a field group with the same image being an information source on a receiving side. CONSTITUTION:An information signal which can be discriminated that it is the field group with the same screen being the information source on the receiving side is multiplexed to a presently executing television signal at present in use and transmitted. For example, at the time of reproducing a television cinema image generated from the film of 24 frames per second, generally, a first one frame is made to correspond to television three fields, the next frame is made to correspond to the television two frames, a method for repeating this combination every 1/12 seconds is adopted and on a transmission side, for example, the binary information signal is multiplexed to the unused line of the vertical blanking period of the television signal and transmitted. On the receiving side, that field groups A1-A3 are signals obtained from the same screen and the two fields of fields B1 and B2 are the signals obtained from the same screen can be discriminated. Such information signals are multiplexed to the unused line of the vertical blanking line of the television signal and transmitted.
