TH9877EX - Television receiver with a switching signal in its memory. - Google Patents

Abstract

The secondary video signal (24) will be illustrated. Digitized and combined with in-memory switching (SS) signals, the combined digital signals are stored in memory, the video signals entering randum ( 900) The stored signal is read out synchronously with the synchronization signal component of the primary video signal, the switching signal is retrieved from the unit's transmitter. Memory and compare it with the content code signal (CSS) to develop a fast switching signal (FSS). The video switch (80) is attached to receive the primary video signal and collect the secondary video signal and respond to the Fast switching response supplies one of the two appropriate input signals to the kinescope (94) to determine the secondary sub-image within the large primary image.

Claims (1)

1. The TV signal processing system (TV) consists of the first video source, FVS, the second video source, SVS, which includes a sampling section attached to receive the V signal. These two DOTs and FCS timing signals with fcs frequency for developing second-speed video samples are The resulting m-bit digital signal is synchronized with the signal. The timer where m is a positive integer greater than one source of the SS switching signal with n-bits, where n is more than one positive integer. Part for linking bit B
