Abstract:
1. A de-interlacing system, comprising: a first field buffer having an input terminal to receive fields successively entered and temporarily store an entered field as a next field, while a field to be entered into the first field buffer is a next-two field; a second field buffer connected to the first field buffer for receiving the next field in the first field buffer and temporarily storing the next field as a current field; a line buffer connected to the input terminal, the first field buffer and the second field buffer for temporarily storing partial line data of the current field; a motion adaptive de-interlacer (MADI) connected to the line buffer for producing a de-interlaced video frame according to the partial line data; a film frame generator connected to the line buffer for producing a de-interlaced film frame signal according to the partial line data; a film signal detector connected to the input terminal, the first field buffer and the second field buffer for deciding whether a stream corresponding to the next-two field is a video stream or a film stream based on the next-two field, the next field and the current field, and accordingly outputting a mode index; and a multiplexer connected to the MADI, the film frame generator and the film signal detector for selecting the de-interlaced video frame or film frame as an output based on the mode index.
