Abstract:
1. A method of dynamically controlling a video display apparatus that includes a frame buffer which is configured to receive frames, the method comprising: receiving a plurality of input frames in a video input stream; encoding the plurality of input frames in the video input stream to generate a plurality of output frames; transmitting a first portion of the plurality of output frames at a first output frame rate to the video display apparatus, wherein the video display apparatus displays buffered frames at a display frame rate and the first output frame rate is approximately equal to the display frame rate such that a number of frames in the frame buffer remains relatively constant at a first number; while transmitting the first portion of the plurality of output frames at the first output frame rate, detecting at least one user input; in response to detecting the at least one user input, transmitting, for a predetermined period of time, a second portion of the plurality of output frames at a second output frame rate to the video display apparatus, wherein the second output frame rate is less than the display frame rate such that the number of frames in the frame buffer is reduced to a second number that is less than the first number; and in response to expiration of the predetermined period of time, transmitting a third portion of the plurality of output frames at the first output frame rate to the video display apparatus such that the number of frames in the frame buffer remains relatively constant at the second number.
