The issues associated with the Ieee 1394 and DVI are in large part issues associate with the best way to handle high-end graphics. Is the Ieee-1394 bus able to send the graphics it renders in the set top box to the TV because todays 1394 link (box to tv) transferred graphics seems to me to be insufficient as well as the fact that 1394 implies a decoder because it transfers require compression. DVI has uncompressed base band but the DVI, when connected to a desktop, still requires Ieee 1394 bus. So which will win out, intelligence in the tv or intellience in the Set top?
