Abstract

A method of storing at least one of a plurality of MPEG sections in an MPEG
data stream is provided, the MPEG section having at least one MPEG section characteristic. An MPEG data stream is received and the one MPEG section is filtered from the MPEG data stream according to at least one MPEG section characteristic. The MPEG section is subsequently stored.
