Title:
TELEVISION NET CUE CONTROL SYSTEM
Document Type and Number:
Japanese Patent JPH06276406
Kind Code:
A
Abstract:

PURPOSE: To prevent transmission of an undesired program caused at a change in programs when a program from a transmission station is changed with a program of a concerned station with a television net cue control signal.

CONSTITUTION: A still picture equipment 3 is inserted to an output line from a video switcher 2 at a sender station side, a still picture signal of a program broadcast just precedingly at a program change timing by the switcher 2 is generated and sent to a net line (j). In response to the reception of the net cue signal at a receiver station side, a video switcher 11 is used to select the program of the reception station after a predetermined time. Thus, even when the program change is delayed at the reception station side, since a still pattern of the program from the transmission station before change is obtained, the transmission of an undesired program is avoided.
