Emerging technologies for one-to-many telecommunications

COOPERS is an EU funded project that was created to develop innovative telematics applications. TPEG is used to transmit traffic information via DAB:
The goal of the project is the enhancement of road safety by direct and up to date traffic information communication between infrastructure and motorised vehicles on a motorway section. COOPERS started in February 2006 with the duration of 48 months and a total Budget of more than 16.800.000 €.
Bell and Telus, the two wireless operators in Canada that are based on Qualcomm’s CDMA technology, announced last week their plans to deploy GSM technology jointly. CBC reports:
“BCE unit Bell and Telus both announced Friday they would be making a significant investment in upgrading their networks, adding high speed packet access, or HSPA, cellular technology to their third-generation networks.”
This could have an impact on the mobile broadcasting technology that will be deployed in Canada. The natural link between CDMA and MediaFLO is quite strong since both technologies belong to Qualcomm. Could this mean less chances for MediaFLO to establish in Canada?

Last year I reported that the Superbowl was not available off the Net. After my positive experiment last summer with the soccer WorldCup 2006, I knew I should be able to access a live peer-to-peer stream of the Superbowl somehow. Well, thanks to Technorati and this post at The Frog Blog, I was watching the show live within a minute.
Here you see the two live scenes I could watch simultaneously earlier tonight; a wifi notebook with the P2P TVUPlayer software and my plain old 36″ tube. I observed a one minute latency on the notebook.
Like the WorldCup on TVAnts, the stream robustness was impressive. Once it got started, the stream simply never stopped. Its data rate fluctuated between 350 and 400 kbps. This is not great video quality but when that’s the only signal you have access to, it’s far better than nothing. For myself, I was happy to see the original CBS Superbowl commercials live for the first time. Here in Canada, the original commercials are always “Canadianized” by the local networks except on some pricy pay TV services.
So overall, it looks like P2P streaming works well. However, TVU Networks statistics would be required in order to really be able to assess what’s going on here. Also, I don’t know at this point if TVU is a pure P2P solution of if they rely on additional servers or CDNs to provide critical capacity.
Although I find these new P2P developpments very exciting, the real new trend in the States this year was certainly HD TV. With their new HD wide screens, sports fans got closer to mother nature this year; they could enjoy and observe each and every raindrop that fell on the field in Miami Gardens!

In his EBU seminar report titled "From P2P to Broadcasting", Franc Kozamernik concludes:
Broadcasters have no choice but to adopt P2P technology and adjust it to their needs. In so doing, broadcasters should coordinate their activities closely with Internet Service Providers (ISPs) and P2P service/technology providers.
Thanks to P2P, the Internet (both wired and wireless) may become not just a complementary delivery channel (as it is today), but indeed a primary channel for niche content and on-demand services.
I strongly agree with this and as I probably mentioned here already, P2P is good for broadcasters but also for the the whole user generated media (UGM) community. With P2P, anyone can afford "large coverage": the distribution network is free. That’s why broadcasters have to do the same.
However, I would argue that P2P networks would be good for the head of the Longtail as well as for niche and on-demand content. In fact, P2P networks are much more efficient for content that is popular. In this case, many more seeds provide a much better and faster access to the desired content.

So I’m sitting right there, waiting for the event to begin.
Beyond Broadcast 2006 is loaded with great, experienced speakers with all possible backgrounds: braodcasters, journalists, technologists and so on. The theme is important:
We will explore the thesis that traditional public media — public broadcasting, cable access television, etc — face a unique opportunity to embrace new participatory web-based media models — podcasting, video blogs, social software, etc — and create a stronger and more vital public service.
And if I’ m lucky, my MMB demo will work fine this afternoon! I’ll try to report later.

PanAmSat Holding Corp. is starting a new business that will sell and distribute ethnic programming for television in the United States, a move that the company hopes will pave the way for other new initiatives that get the satellite company into more consumer businesses such as Internet video and mobile phones.
Our canadian public broadcast engineers from CBC/SRC published in January the first issue of their new bi-annual Technology Review . As Ray Carnovale (VP and CTO) puts it in his editorial : This semi-annual electronic publication will give an opportunity for us at CBC/Radio-Canada to describe and promote the significance of our activities in the Technology group, and to share our ideas both inside and outside the Corporation. As a service group, our role is to bring our collective knowledge and expertise to enable the infrastructure for our media partners to create the highest quality programming for the Canadian public. I like the WEB/PDF format that we also enjoy from the very famous EBU Technical Review . I think it’s a great initiative and I’m looking forward to read about CBC’s views on the future of broadcasting…. or, well, broadcasting 2.0!
IPWireless Mobile Broadband technology is a packet data implementation of the international 3GPP Universal Mobile Telecommunication System (UMTS) standard. Time-division-duplex (TDD) is used, according to the 3GPP UMTS UTRA UMTS TD-CDMA standard, allowing operation on unpaired spectrum anywhere in these bands. Chip rates of 3.84 and 7.68 megachips/sec (Mcps) are supported, for operation in channelization of 5 and10 MHz (6 and 12 MHz in the MMDS band).
