"Peter Biddle"@en . "In 1998, Biddle was the first person to ever publicly demonstrate real-time consumer DVR using an inexpensive MPEG2 HW encoder, at WinHEC. Biddle was the author of \u201CThe Biddle Diagram\u201D on page 13 in the SDMI spec, which enabled the playback of \u201Cunknown\u201D (e.g., potentially pirated) content on SDMI-compliant players, and was a vocal proponent within SDMI for the external validation of digital watermarking. Biddle is a member of the Biddle family and is a descendant of Nicholas Biddle.
