    摘要: Interpolated scan lines are produced in response to received video signals which are comprised of conventional interlaced scan lines constituting successive fields. A delay circuit, preferably formed of field memory devices, such as three cascaded field memories, functions to delay the received video signals to provide a first scanned line signal in a given field, the next succeeding scan line signal in that field, an interlaced scan line signal in the next succeeding field and an interlaced scan line signal in the next preceding field. A first combining circuit combines the signal values of the next succeeding field interlaced scan line signal and the next preceding field interlaced scan line signal to form a first combined scan line signal. A second combining circuit combines the signal values of the first scan line signal in the given field and the next succeeding scan line signal in that field to form a second combined scan line signal. The first and second combined scan line signals are level adjusted and added to produce an interpolated scan line signal intermediate successive main scan lines in the given field.

    摘要: The present invention is related to a video signal processing apparatus and method, a recording medium, and a program which are suitably for use in determining whether an input video signal is standard or nonstandard. In synchronization with the edge of an advance vertical sync signal xAVD, a free-running vertical sync edge counter 31 increments by 1 the count value which cycles between 0 through 7 and outputs the count value to a free-running field ID edge counter 32 and a comparator 33. In synchronization with the rising and falling edges of a field ID signal AFD, the free-running field ID edge counter 32 increments the count value by 1. The comparator 33 generates a nonstandard signal detection signal in correspondence with the FD edge count value with the V count value being 7 and a vertical sync signal xVD being at L level. The present invention is applicable to TV receivers for example.
