Various embodiments for switching programs streams using a fixed speed program stream buffer coupled to a decoder are described. Various embodiments for switching programs streams using a fixed speed program stream buffer coupled to a decoder are described. In one or more embodiments, the fixed speed program stream buffer may be arranged to receive multiple program streams, such as video program streams, and to buffer historical frames comprising at least one anchor frame. Upon detecting a channel switch point, the most recent historical anchor frame prior to the channel switch point may be provided to the decoder. After receiving the anchor frame, the decoder may be arranged to start the next frame after the anchor frame instantly. Once the most recent historical anchor frame is played in to the decoder, the decoder may pick off the next frame after the anchor frame at a normal cadence. A program stream may be run in a delayed state by the decoder from an alternate channel buffer activated in response to a channel change. Other embodiments are described and claimed.

Various embodiments for switching programs streams using a variable speed program stream buffer coupled to a variable speed decoder are described. In one or more embodiments, the variable speed program stream buffer may be arranged to receive multiple program streams, such as video program streams, and to buffer historical frames comprising at least one anchor frame. The variable speed program stream buffer may be arranged to always comprise at least one anchor frame and may be implemented by running and/or elastic buffers corresponding to an active channel program stream and one or more alternate channel program streams. Upon detecting a channel switch point, the historical frames comprising the anchor frame up to the channel switch point may be provided to the variable speed decoder in an accelerated manner. The historical frames may be provided to the variable speed decoder in a very short time instant or burst, such as within a time interval of one frame count or less, to enable the variable speed decoder to catch up to the notion of real time. Other embodiments are described and claimed.

A method includes providing a display device. The display device may include a plurality of picture elements and a plurality of pixel drivers each for driving a respective one of the picture elements. The method may further include receiving input image data to drive the picture elements to display an image in an image plane. The method may also include receiving user input to indicate a shift in position of the image in the image plane. The shift in position may be by less than the distance between adjacent picture elements. In response to the user input, the input image data may be processed to generate interpolated image data to implement the shift in position. The picture elements may be driven with the interpolated image data.
