Patent ID: 8259233

Claim:
A system for processing a television picture-out-picture, comprising: a multiplexer for receiving partial pixels of a first picture and partial pixels of a second picture and outputting the partial pixels of the first picture and the partial pixels of the second picture in multiplexing; a line buffer connected to the multiplexer for receiving partial pixels of the first picture and partial pixels of the second picture for output; an image processing engine connected to the line buffer for performing an image processing on the partial pixels output by the line buffer to produce processed pixels corresponding to the partial pixels of the first or second picture; a scaling engine connected to the image processing engine for performing a scaling operation on the processed pixels to produce scaled pixels; a timing generator connected to the image processing engine and the scaling engine for producing a timing signal for the image processing engine and the scaling engine and producing enable signals respectively for the first picture and the second picture; an image synthesizer connected to the scaling engine for synthesizing the scaled pixels to produce an image signal with a POP video effect; and a first multiplexer, which is connected between the line buffer and the image processing engine and has two input terminals connected to the line buffer for selecting the partial pixels of the first or second picture as an output; wherein when the timing generator generates the timing signal and the enable signal for the first picture in a first time interval, the image processing engine receives partial data of the first picture, performs the image processing on the received data, and outputs the processed data; and when the timing generator generates the timing signal and the enable signal for the second picture in a second time interval, the image processing engine receives partial data of the second picture, performs the image processing on the received data, and outputs the processed data.
