Title: Tbc circuit
Inventor: OKURA JIRO
IPC: H04N9/896
Filed: 1995-08-01
Abstract: PROBLEM TO BE SOLVED: To prepare a black burst tape by an instruction from an outside by rewriting the contents of a memory to a black level, repeatedly reading them and adding burst signals and synchronizing signals. SOLUTION: Since the contents of the memory 4 are reset to '0' when power is supplied, black burst signals for which the burst signals and the synchronizing signals are added to the video signals of the black level are outputted from an encoder. When video input is not present, the output of a synchronization separating circuit 13 becomes LOW. In this case, when FG signals HIGH are inputted to a memory controller 8, all the contents of the memory are cleared and write thereafter is inhibited. As a result, the video signals of the black level for which the burst signals and the synchronizing signals are added to the video signals inside the memory 4 are repeatedly outputted from the encoder 7 and turned to black burst output.
