を特徴とするテレビジヨン放送受信処理装置。 A television broadcast reception processing device equipped with a digital video processing circuit 7 that combines video signals of multiple channels sequentially received by a tuner and creates a composite video signal for configuring a monitor screen to be referred to during channel selection operation. In this case, a plurality of tuners 3 and 4 are connected to the output end of a tuning circuit 1 that emits a series of tuning signals for sequentially tuning broadcasts from multiple channels.
are connected in parallel to each other to sequentially send the tuning signal for each channel to each tuner, and the signal received by each tuner is continuously connected to the digital video processing circuit 7 via the switching circuit 6. A television broadcast reception processing device characterized in that the time required to display a composite video signal on a monitor is shortened by simultaneously performing a channel selection operation using a tuner.
