I still waiting for information on the older (more than 2-years old) set tops that have Docsis tuners and receive Multicast video.
They would not have a Docsis tuner, due to the Docsis tuner is in the Head End. A TV has a ATSC, QAM tuner, some may still have NTSC tuners also if they are older.
This is what a docsis tuner does:
"DOCSIS 3.0 Tuner
Product name: MicroTuner MT2170
Features/what it does: 1 GHz input tuner based on DOCSIS 3.0; engineered to deliver data speeds greater than 160 Mbps 100 MHz bandwidth; offers equivalent functionality of four DOCSIS 2.0 digital tuners in a miniature package; when integrated into cable modems or VoIP set-tops, delivers speeds greater than 160 Mbps; single-chip tuner optimized to receive and tune RF from 50 MHz to 1 GHz; supports the DOCSIS 3.0 channel bonding technology; can accept bonded channels within bandwidths up to 100 MHz when paired with a DOCSIS 3.0-capable demodulator."
A little bit more about what the Docsis Tuner does for the Cable modems, which also includes Digtal Subscriber Set Top Boxes:
"Tuners for DOCSIS 3.0 cable modems
Cliff Anderson, Microtune, Inc.

The DOCSIS 3.0 specifications enable cable modems to achieve unprecedented uplink and downlink data rates, and it comes not a moment too soon. The growing market strength of telecommunications service providers' fiber-to-the-home (FTTH) services is mounting a significant threat to cable operators, and the race is on to achieve DOCSIS 3.0-network class speeds to stay in the competitive game and win the consumer.
The new DOCSIS 3.0 specification enables cable modems to provide data rates approaching 160 Mb/s downstream and 120 Mb/s upstream to compete with fiber's 100 Mb/s downstream and 100 Mb/s upstream. DOCSIS 2.0 data rates are limited to nominally 40 Mb/s downstream and 30 Mb/s upstream. Never before has time to market been so important to cable modem manufacturers and cable service providers.
One of the top priorities in this race has been the need for a wideband tuner, one that handles the wide IF bandwidth employed in DOCSIS 3.0 and that delivers the performance necessary to achieve reliable data rates.
Fortunately, there is now a single-chip silicon tuner available today with the impressive performance and necessary IF bandwidth required to support DOCSIS 3.0 modems. This drop-in device comes from Microtune, a dominant silicon tuner supplier to the cable market, and its new MicroTuner MT2170 wideband tuner is poised to revolutionize the cable modem industry."

Only way that there would be a way of interpreting Docsis, is if they had a Cable Card in the set. You like BiggAW as I have already stated, both of you do not get it, what the technology is, or have even gone out and looked at the info, which I have, and also have known about this stuff for over 20 years, how it works.
So just like I told BiggAW, I am done arguing with you also, because it is pointless beating my head against the wall trying to get both of you to understand how this stuff works, even though the information was placed right in front of both of you, directly from the equipment manufacturers, and other citations.
Just face it, both of you really need to grow up and listen to the adults, when they try to explain stuff to both of you, instead of acting like a couple of children. I really cannot wait to see what you come back, that you just pull out of your seat. Just really face the facts YBSane, you really are going to continue losing this fight, because you have already shown that you do not have a clue what you are talking about.Edited by gregzoll - 4/14/13 at 3:07pm
