Getting The Most Out Of Your TiVo

What Should I Expect To See Inside My TiVo?

Before we remove the cover, we want to take a peek at what's underneath it. You will notice that there is an IBM PowerPC chip; it is running at a whopping 54 MHz. For all that the TiVo can do, 54 MHz of processing power sure doesn't sound like a lot. You would think that more processing power would be needed to handle all of the MPEG2 video encoding and decoding, but the fact is that the TiVo has a hardware-based MPEG2 encoder/ decoder, so it doesn't need additional processing power. TiVo has its own special chip embedded in there as well, called the "Media Switch." There is also a built-in V.90 modem TiVo uses to make its daily "call home." You'll notice a standard IDE connector just like the one that is in your computer. There is a proprietary connector that looks like a PCI connector. Unfortunately it's not, but some TiVo users have figured out how to attach an Ethernet adapter to it. With the Ethernet adapter, the "call home" is done through your broadband connection, not the modem. The RF modulator is the silver brick that your coaxial cable hooks into. The modulator takes the output from the TiVo, and converts it to Channel 3 or 4 for display on your television.
