Patent ID: 7307669

Claim:
A system for providing a video signal comprising scaled frames, said system comprising: a decoder for decoding a plurality of frames, wherein the plurality of frames comprises a first one or more frames associated with old display parameters, and a second one or more frames associated with new display parameters, and transmitting a signal after receiving the second one or more frames; a display engine for scaling the first one or more frames associated with the old display parameters after receiving the signal from the decoder; a controller for setting a timer with a predetermined period of time responsive to a vertical synchronization signal, comparing timing data associated with the new display parameters to a time reference, after the expiration of the predetermined period of time and transmitting another signal to the display engine if the timing data associated with the new display parameters is within a predetermined range from the timing reference; and wherein the display engine scales the second one or more frames with the new display parameters, after receiving the another signal from the controller.
