Patent ID: 8270821

Claim:
A media data playback device, comprising: a receiver operable to receive a media data stream; a buffer unit comprising a first buffer, a second buffer and a third buffer; a capture unit operable to duplicate and store a first section of the media data stream as a first copy and a second copy in the first and second buffer respectively, generate and store a third copy of the second copy in the third buffer in response to a replay command, wherein the first copy and the second copy in the first and second buffers are updated by a second section of the media data stream; a parser unit operable to simultaneously parse the second section from the first buffer utilizing a first parser of the parser unit and parse the third copy from the third buffer utilizing a second parser of the parser unit; a decoder unit operable to simultaneously decode the parsed second section utilizing a first decoder of the decoder unit and decode the parsed third copy utilizing a second decoder of the decoder unit; and a composer operable to compose viewable signals from the decoded third copy and the decoded second section.
