Abstract:
1. A method for switching from playing a first compressed data segment to playing a second compressed recorded data segment, the method comprising: retrieving an uncompressed copy of a start of the second compressed recorded data segment from a non-volatile storage; playing the uncompressed copy of a start of the second compressed recorded data segment upon switching from playing the first compressed data segment; decoding the second compressed recorded data segment from a preceding random access point, the preceding random access point preceding, in the second compressed recorded data segment, a point at which playing is to be switched to the second compressed recorded data segment, wherein for at least some of the time while the uncompressed copy is provided for display, the second compressed data segment is being decoded; stopping the decoding of the second compressed recorded data segment when reaching a point beyond a point currently being played in the uncompressed copy; and switching from playing the uncompressed copy to playing the second compressed recorded data segment when playing the uncompressed copy of the start of the second compressed recorded data segment reaches the point at which the decoding of the second compressed recorded data segment was stopped.
