Title: Television relay system
Inventor: MURAI YOSHINOBU
IPC: H04N7/20
Filed: 1988-05-10
Abstract: PURPOSE:To smoothly switch a television program of a key broadcast station and a television program of a local broadcast station by detecting whether or not a key broadcast station television signal received by an identification signal detection circuit is via a satellite communication line. CONSTITUTION:Only when a key broadcast station television signal 15 is sent from a satellite communication line, an identification signal insertion circuit 10 inserts a satellite communication line identification signal 9 to the key broadcast station television signal 15. In a local broadcast station 7 receiving the key broadcast station television signal 15, an identification signal separation circuit 11 extracts a satellite communication line identification signal 9. When the key broadcast station television signal 15 is given via the satellite communication line, a delay of a transmission delay time TD is caused due to the satellite communication line. Thus, the local broadcast station 7 retards the timing of changeover from the local broadcast television signal 16 to the key broadcast station television signal 15 by TD. Thus, the television program of the local broadcast station 7 and the television program of the key broadcast station 6 are switched smoothly.
