(May 24, 2001) -- Personalized television company TiVo announced that the U.S. Patent and Trademark Office has issued it a patent covering many of the tools associated with personal video-recording software and hardware design.

TiVo has a previous patent for a "multimedia timewarping system," originally filed in July 1998. The new patent covers: a method for recording one program while playing back another or watching a program as it is recording; a method for efficient and low-cost processing and synchronizing of video, audio and closed-captioning; and a storage format supporting Trickply, which includes pausing the live TV broadcast, fast-forwarding, rewinding, instant replays and slow motion. -- Adrienne Mand
