Abstract
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.
