Advertisements http://www.arrisi.com/products/product.asp?id=992 My cable company uses this DCT700 ALL-DIGITAL CABLE SET-TOP when it doesn't want to use TiVo. 1) without a cableCARD how do these devices decode? Is there a chip? A signal? 2) I thought the law required cableCARDS in the devices used by the companies. There is a confusing statement in the wikipedia article. Use of the term CableCARD can be confusing, because some technologies refer not to the physical card, but to a device ("Host") that uses the card. Some CableCARD technologies can be used with devices that have no physical CableCARDs. 3) Are such devices inherently limited to standard definition? 4) Why can't I purchase such a device? Is it technical or legal limitation? The retail rental rate is $10/month for a stupid little device like this one.
