Abstract:
A method for unpacking a first framed information stream having a first bitrate from a second framed information stream having a second bitrate, said second bitrate being greater than said first bitrate, said first framed information stream having at least two elementary streams that are temporally offset from each other, said method comprising the steps of:(a) storing, in a first buffer, a first portion of said second information stream; (b) storing, in a second buffer, a next portion of said second information stream; (c) reading said first portion of said second information stream from said first buffer in accordance with a delay that corresponds with the temporal offset between the at least two elementary streams to form a portion of the first framed information stream; and (d) reading said next portion of said second information stream from said second buffer to form a next portion of the first framed information stream where a timing gap within the at least two elementary streams is removed.
