Patent ID: 8913883

Claim:
A multiformat video playback device compatible with a video signal based on a plurality of types of formats, and configured to convert an input video signal into a video signal of a specified size and a specified format, and output the converted video signal comprising: an input processor configured to capture the input video signals corresponding to one frame, and convert the captured video signals into progressive video signals according to an instruction of control information; a scaler configured to resize a video signal output from the input processor to a video signal of a size specified by the control information; a frame buffer configured to sequentially store therein the resized video signals corresponding to one frame; an output processor configured to read the video signals stored in the frame buffer according to a format specified by the control information, and output the read video signals; a controller configured to create control information including a conversion instruction intended for the input processor, size specification intended for the scaler, and format specification intended for the output processor, and supply the created control information to the input processor; a first delay section configured to delay the control information supplied to the input processor by one frame, and supply the delayed control information to the scaler; and a second delay section configured to delay the control information supplied to the scaler by one frame, and supply the resultant control information to the output processor.
