摘要
A widescreen television signal containing center panel information and time compressed side panel information in an overscan region is intraframe processed above a given frequency only with respect to the center panel information. The intraframe processing apparatus includes a signal delay network with first and second 262H delay elements coupled between an input and an output of the delay network. During a first field interval, signals from the delay input and from an intermediate point between the delay elements are subtractively combined to produce a difference term which is coupled to a signal path. During a second field interval, signals from the delay output and from the intermediate point are subtractively combined to produce a difference term which is coupled to the signal path. An intraframe processed output signal is produced by combining the difference terms from the signal path with a signal from the intermediate delay point. A filter and an electronic gate in the signal path determine frequency selective intraframe processing of the center panel information alone.
