| Re: Oh Nice... When both ends of the connection equipment are certified for it.
Many of the current CMTSs cable companies use can be upgraded to DOCSIS 3.0 without total replacement of the gear, but there aren't any real DOCSIS 3 modems certified or available yet.
...
1 Ghz tuners, MPEG4, SDV, and DOCSIS 3.... that should work out nice with all the recent upgrades I've seen TWC doing lately. Wonder if Verizon FIOS will do anything with those new boxes.... I'm sure they'd like MPEG4 and 150 Mhz of extra channel space. | |

| Re: Oh Nice... Actually it's about twice as thick as an Arris. But remember it has a built in cordless base station. The batteries really aren't that big. The one in my Arris is smaller than my camcorder battery.
The size is partly for ventilation. There is a lot of air space in the cases of these units. All of those electronics operating inside a single case generate a lot of heat. The heat is increased further when the battery is charging or discharging (i.e. being used for backup purposes).

| Obviously more compression = more data in the same bandwidth, but does MPEG-4 offer lossless compression or just lossy? I'd think people would be clamoring for uncompressed, higher quality HD content.

| Re: Refresh my memory MPEG is designed for lossy compression. It's just designed so that you won't notice the compression unless the video is highly compressed. Given the desire to keep adding more channels I don't think you will ever see uncompressed HD video on cable or satellite.
To get back to what you probably meant to say, I don't think you will see lossless HD video on cable or satellite. Maybe a channel or two for special events but the majority will be heavily compressed so they can put in more HD channels. Now with Switched Digital Video they might could go to uncompressed video, or lossless compressed video but I doubt that will happen. | |

| Re: Refresh my memory For most people the compression isn't visible. What is visible is how well the signal is handled before and after it gets compressed.
A first generation transcode of a 1080i uncompressed feed compressed w/ MPEG4 looks pretty much as stunning as the original (except for fast motion).
The big problem is that in most cases the cable company (and the satellite providers to some extent) is recompressing and retranscoding a signal that has already been compressed or degraded somewhere else along the way.
Here, DirecTV and DishNetwork have an advantage when it comes to national channels. They only have to get the original signal back to 1 main location. For the cable companies they need that same national signal available to each and every head-end. That enables the satellite companies to spend a little more to get a good signal back for those channels - i.e. direct fiber feeds from the originating programmers instead of pulling it off of c-band or similar.
Now for local channels it's the opposite. Satellite companies have to push all these local broadcasts back to their main hub. Pulling all those locals in costs a lot of money. To maximize capacity, most of them are highly compressed in transit. The cable companies can pull the native format signal out of the air locally with much less trouble and potentially no backhaul. Or for larger/remote cities they may have a fiber feed from the local TV station.

| Re: will verizon use this for fios tv? Fios uses a 54-862/870MHz 'plant'.
Where are you getting the information that FiOS is 'capped' at 750MHz???
Go back and read the video specs on the most common Tellabs 612 ONT that Verizon uses: »www.tellabs.com/products/1000/tl···_612.pdf
Tellabs gives it a spec in at 870MHz.
Still the same 1550nm wavelength supplied video over the PON, just add ONT capable of RF output for 23 more 6MHz 256QAM channels, the current ONT's might actually be able to stretch the extra headroom already, the next generation of QAM/IP boxes will fit in nicely.
The cables and splitters are already up to spec, and no Interference to MoCA occurs until 1125MHz.
No DOCISS needed with FiOS, 1125MHz-1425MHz MoCA handles 2-way Data and IPTV on the COAX.
1310mm and 1490nm light handle it on the fiber.
Oddly enough, newer cable boxes will also incorporate MoCA, as other cable operators are clamoring for the Multi-Room DVR concept, which needs MoCA connection between boxes on the COAX network to communicate with each other.

There isn't even a standard out for RF broadcast tv over PON at 1 GHZ. The new MPEG4 boxes do have MOCA options available. The current FIOS boxes aren't "fundamentally different", it's pretty much the same boxes many cable companies use with the addition of MOCA. The latest DCH boxes from Moto and these new MPEG4 boxes could all be used on either FIOS or cable with little issue as they all have MOCA included or as on option. DOCSIS tuners are probably already in some of the current FIOS boxes, they're just sitting there unused though.
"Fundamentally different" would be ATT Uverse or even DBS boxes as neither of those can use the Moto cable boxes.
Also, currently FIOS uses 860 Mhz of video bandwidth not 750 Mhz. As far as I know, that's more a limitation of the tuner in the cable boxes, not of PON technology. So expanding the video bandwidth to 1 Ghz should be a no brainer if they use these new boxes. | |

Its not the encoding technique, its the bitrate ATT uses. ATT is scared to turn it up, since then more bandwidth is needed, and it can knock out customers on poor VDSL lines (existing copper problems, long loop to VRAD), or use all 3 set top boxes at once. | |

I know better.. We haven't seen Motorola come out squeaky clean on docsis 3.0 interop testing... cmts and set-top cablemodems.

| What about CableCard though? Wont MPEG4 be incompatible with digital TV though (without a set-top box)? Thew whole point of CableCard was to get rid of the ugly, bulky boxes. For a CableCard-type setup to work with this new scheme; it'll require new TV's. And then in another decade, when they want to change the scheme AGAIN to whatever facing compression/encoding mechanism of the day is hot.
(I realize CableCArd 2.0 is going to require new TV's ANYWAY; but we can't ber repeating this process every 10 years. Unless, of course, there a remove module for the compression/encoding too. I know for most people CableCard 1.0 is inadequate but keep in mind it was conceived over a decade ago, but the digital TV deployment and POD cards were excessively delayed due to foot-dragging by the industry.
Are we really going to be stuck with these infernal boxes forever? | |

| Good Yay! Slightly late for MPEG4 Part 10 (H264/AVC), but not by leaps and bounds. (Definately late for MPEG4 Part 2 (including XVID/DIVX/Nero Digital), which they skipped, which they shouldn't have, but that's the USA corporations for you.)
This is good news indeed.
I actually didn't know they didn't have this already. That's how late I think they got to it. I hope they used all the extra time they took to make a really good product.
Edit: I am especially pleased that Motorola thinks MPEG2 will be obsolete in less than two years. It almost admits that they introduced MPEG4 capability pretty near the end of the demise of their designated predecessor encoding standard (MPEG2, since they skipped MPEG4 part 2 which was out and very useful for a long time compared to MP4 part 10). It might also be a kick in the butt of the Comcast planners that put out orders for a zillion MPEG2-only set top boxes for low end connections. I truly hope Comcast goes the route of offering higher end channels on these better quality encoding boxes, so that they can transition better (i.e., quicker, this late in the game). | |
