The executive penny pincher is actually the guy who launched the higher upstream trials with a statement he made a few months about about 10Mbps upstream trials to keep up with BT's NGA services  |

interesting...., were are all the other geeky interests in pulling all the geeky tech treads, and related VM onfo off the beaten track news sites all together here these days anyway
regarding using generic multicast streaming and that other hybrid transport gateway STB's i pointed out as potential use for VM, that can handle both RF and IP-based video etc i posted elsewere but cant be bothered to find the related long time threads....
take a look at these news posts, and connect the dots, but remember, we are talking VM executives looking for lower BOM, so i expect its not going to be as inovative as you might expect, but you never know, the new quarter only penny pincher might see the light and be pushed think far longer term...when they sign the newest mass (millions at a time now given its all one network now)CPE box agreements for long term use and rental returns.

Virgin Presses 'Play' on TiVo
November 25, 2009 |
Jeff Baumgartner
..
TiVo Inc. (Nasdaq:
TIVO) is taking its partnership act to the U.K. in a big way, notching a deal to develop a next-generation TV platform for
Virgin Media Inc. (Nasdaq:
VMED) that will include broadband-fed video services and applications.
TiVo, which announced the deal in concert with its third-quarter earnings, said it's on board to develop a "converged television and broadband interactive interface" for Virgin's upcoming high-definition set-top boxes. (See
Virgin Media Picks TiVo.)
Virgin has not unveiled a roadmap for those boxes, but industry sources say the MSO is eager for hybrid transport gateways that can handle RF and IP-based video --
Virgin is ambitiously upgrading its content delivery network to handle more IP traffic --
and be capable of taking video from the Web. (See
Gateway to (Video) Heaven?)
Virgin says the set-top platform, co-branded with TiVo, will debut sometime in 2010. (See
Virgin Taps Cisco for Video Upgrade .)

Gateway to (Video) Heaven?
September 30, 2009 | Alan Breznick
...
It may be time to make way for cable's new video gateway.
Also known as the video transport gateway, hybrid QAM/IP gateway, or cable
multimedia gateway, this proposed advanced set-top box (STB) has been picking up steam as the next hot cable device over the last few months.
As the first autumn
Society of Cable Telecommunications Engineers (SCTE) Cable-Tec Expo approaches in Denver later this month, equipment vendors are increasingly promoting the gateway concept as the best way for cable operators to deliver IP video to the home without changing or disrupting the rest of their service delivery networks..."
"As envisioned, these multimedia gateways would allow cable providers to deliver converged, IP-based video, voice, and data services to the TV, as well as pump video to other IP-connected devices in the home, by using embedded Docsis 3.0 cable modems and encapsulating traditional QAM-based digital video with IP packets. "
"
Motorola Inc. (NYSE:
MOT) are all developing or refining their own multimedia gateways that can blend together traditional QAM-based digital video with newfangled IP-based video.
In fact, Motorola just demonstrated the latest version of its hybrid QAM-IP "transport gateway" at the
IBC Show in Amsterdam last month, while Hitron Europe and ADB also unveiled new cable gateway lines. "

Virgin Taps Cisco for Video Upgrade
September 11, 2009 |
Jeff Baumgartner
...
Under a deal announced Friday at the IBC show in Amsterdam, the U.K.-based MSO is set to upgrade its regional and central headends with a wide range of IP core and edge network gear from the equipment vendor.
Financial terms weren't disclosed, but the deployment includes Cisco's 7609 routers, 4948 10-Gigabit Ethernet switches, digital content manager, RF gateways,
and the vendor's multicast manager and "ROSA" control/monitoring system. (See
Cisco Lands Virgin Upgrade Deal.) "
.....
"Although IP-based content distribution is central to the upgrade, the MSO hasn't revealed much about how it will use the updated system to offer additional managed IP video services (beyond using it to deliver video-on-demand), or if it will even consider using it to help customers pipe in "over-the-top" Web-based video directly to TV screens.
Today's announcement did note, however, that the new "simplified infrastructure" will help Virgin Media "support the rollout of new conditional-access security services," indicating that the MSO may be looking to offer a new range of IP-based services using digital rights management (DRM) systems."
....
"
"The agreement with Cisco is to help enhance our existing TV platform, which broadcasts content over DVB-C [Digital Video Broadcasting – Cable], and then our VoD service runs on IP," she noted.
Indeed, Virgin Media and Cisco have been working together for some time on figuring out how the MSO can more efficiently transport video content -- especially
British Broadcasting Corp. (BBC) 's popular iPlayer service -- across its network. (See
Virgin Media Weighs CDN Options.)
Whatever services Virgin ends up developing following the upgrade, it will certainly involve the use of
Docsis 3.0, which the MSO is using today to offer a 50-Mbit/s downstream tier in all its systems.
It's also conducting a 200-Mbit/s trial, which bonds together four 8 MHz channels, in Ashford, U.K. with Cisco . (See
Virgin Takes Fight to Its DSL Rivals and
Virgin Bonds With 200 Mbit/s Trial .)
And industry sources have indicated that Virgin is eager to deploy a new breed of hybrid cable gateways that can feed in both traditional QAM-based video as well as IP-based content using embedded Docsis 3.0 modems.
Using
Multimedia over Coax Alliance (MoCA) , or other high-speed home networking systems, those gateways can shuttle video and other digital media to multiple screens in each home....."
in a nutshell it seems somone in Vm are looking to use the Docsis3 for a real STB hybrid gateway supplyed by Cisco.
ready to upgrade their multicast routers and related kit to faster multicast IP end to end.
upgrade its regional and central headends with a wide range of IP core and edge network gear.
take a brand NEW STB hybrid gateway CPE kit (hopefully this time with something thats got at least as much power in its chipset as your average mobile phone, running say Arm
Cortex- A9/NEON SIMD Media Processing Engine or at least a Cortex- A8/NEON 800 Mhz) sat on your desk.
and potentially allowing some form of secure streaming to and from any IP based PC or DLNA capable device sat on your LAN, although DLNA doesnt seem to be on the menu and thats a missed long term chance if they dont put a simple DLNA java client/server and HDML GUI on there OC...
and having a new?
TiVo (java?) codebase run on top of this new gateway/STB to some form of backend carousel thats hopefully going to totally replace all the super slow liberate and its matching backend! ,ready for rollout sometime in 2010!...
so given these moves, were does upgraded upload rates sit in all this, as the return paths for this dont really need more than a single IP return channel, although clearly they will need more than the current STBs use (512Kbit/s up and down ?) OC.
its odd though the talk is DVB-C upgrades and not DVB-C2 today for the long term...shades of the VM Executive once again Not thinking longer term HW outlay enough there again.
