Abstract

PURPOSE:To receive and display a selected program without any waiting time by selecting a channel and storing all programs of all object channels in the state of a picture data. CONSTITUTION:In selecting the channel 1 by a tuner 2 through the operation of a remote controller 19, the channel 1 is selected from a video signal from an antenna 1, a teletext signal is extracted by an extracting circuit 3, converted into a digital signal and stored into a teletext signal memory 4 by a program data per 1Vd. The stored program data is transferred and stored sequentially in a picture memory 9 in place of a picture signal by a picture processing CPU 6 before the Vd period. Similarly, the data is stored as to other channel. In using the remote controller 19 to select an objected program number of an object teletext channel, the program data subject to picture processing is extracted from the memory 9 and the designated program is received and displayed.
