ABSTRACT:
A unified recording format allows both recorded programs and paused buffered broadcasts to be stored in memory as a common virtual stream. As content is received on a channel, it is placed into the virtual stream with newer content at the start of the stream and progressively aging content migrating farther downstream. A front section of the stream effectively operates as a pause buffer, as the currently tuned broadcast program is recorded in this section and is responsive to pause/resume commands. Recorded programs are also stored as part of the same virtual stream. Pointers are used to identify the boundaries of the pause buffer, as well as the beginning and end of each recorded program in the virtual stream.
