Title: Tv receiver for moving body
Inventor: KUBOI TOYOAKI
IPC: H04N5/64
Filed: 1997-01-14
Abstract: PROBLEM TO BE SOLVED: To prevent the screen of the TV receiver for a moving body from becoming hard to see owing to frequency screen switching by ignoring a discrimination signal of EDTV and holding screen size if a video signal is disordered. SOLUTION: A control part 7 decides the state of a horizontal synchronizing signal from a synchronous separation part 5 and controls a video switching part 3 and a screen size switching part 6 to switch the display screen 2 only when the video reception state is good. If the video reception signal is band, on the other hand, the control part 7 holds the screen state irrelevantly to the discrimination signal from an EDTV2 decoding part 4. When the held screen has been decoded by the EDTV3 decoding part 4 at this time, the state at the time of the decoding is held; when the state is normal, it is held as it is, but when not, a return to the synchronous separation part 5 is made without holding the screen state.
