TIVO vs E*

But there aren't any elements in claims 31 and 61 regarding synchronization, so it doesn't matter what format is being used to encode a program digitally.

Um...if audio/video sync matters, mpeg2/mpeg4 matters. Its a simple correlation.

If it uses a 50Hz power source, it must be innovative as 50Hz power sources aren't widely used here in America!

Changing the decoder from only MPEG2 to MPEG2 and MPEG4 is just as innovative.

Kindly explain the technical differences in each so I can better understand your position.

Thanks.

But doesn't TlVo's patent claim talk about 50 Hz or maybe 60 Hz? Surely they talk about one or the other. A DVR can't work without power.

But that is the entire point we've been making all along:

Audio/Video synch matters in the Hardware Claims.

Audio/Video synch doesn't matter in the Software Claims.

For the life of me I cannot find a power requirement within the text of the patent.

The claims were written strictly within the scope of the one technology in use at the time. Now that there are two technologies in play, its a different ballgame. Recognize.

Well, I guess it's irrelevant. I'm sorry I brought it up.

Lol...YOU braught it up! Lol.

Mpeg2 and mpeg4 was at least relevant to the audio/video portion of the discussion.

[vampz26]

Never mind...thomas did...lol

But whatever.

From the TiVo Time Warp Abstract:

A preferred embodiment of the invention accepts television (TV) input streams in a multitude of forms, for example, National Television Standards Committee (NTSC) or PAL broadcast, and digital forms such as Digital Satellite System (DSS), Digital Broadcast Services (DBS), or Advanced Television Standards Committee (ATSC). The TV streams are converted to an Moving Pictures Experts Group (MPEG) formatted stream for internal transfer and manipulation and are parsed and separated it into video and audio components.

Takes a digital satellite system TV stream and converts it to an MPEG formatted stream.

Yep. The claims were written with one format in mind.
