Abstract
A method and apparatus for storing multimedia data for use in a digital VCR includes processing that begins by maintaining a first link list of a plurality of memory sections, where the first link list links the plurality of memory sections as a circular buffer. The processing then continues by receiving a stream of multimedia data. The processing then continues by storing the stream of multimedia data in at least some of the memory sections of the plurality of memory sections. The processing then continues by receiving a request for independent storage of a selected portion of the stream of multimedia data, e.g., the user desires to have a permanent copy of a particular program. The processing further continues by generating a second link list for a set of memory sections of the at least some of the memory sections. The set of memory sections stores the selected portion of the stream of multimedia data. The processing continues by updating the linking of the plurality of memory sections within the first link list without the set of memory section.
