Abstract
The buffer of a programmable video recorder includes a backing store having a plurality of discrete temporary files that are configured to store non-byte streamed data, such as ASF data. The data stream includes a number of data samples that are each assigned a time stamp upon receipt. Each data sample is then assigned and written to a temporary file based on a corresponding duration assigned to each of the temporary files. The backing store operates like a moving window as the oldest temporary files are replaced with the newest temporary files.
