Live Traffic Information on GPS Devices in Canada

December 9, 2009 in Applications, Consumer devices, Infrastructures, Mobility, public broadcasting by Administrator | No comments

In my recent reflexions about the new potential for hybrid radio based on FM I identified RDS-TMC as an incentive to maintain and even expand the FM (RDS) infrastructure in Canada. While speaking about that at a meeting last week I learned that Corus Entertainment was deploying RDS-TMC traffic for Garmin devices in major cities in Canada. I’m not sure how long it has been there but I think it is quite new. And now that I’m aware of that, I see traffic enabled Garmin devices advertised everywhere… and prices are very reasonable.

So last week I ordered a Garmin model 265WT from Tigerdirect.ca (170$). The “T” at the end of the model number indicates that the FM RDS-TMC is included in the box. With such package, traffic information seems to be included for free for the whole life of the device. I’m not quite clear about that but for some reasons, Garmin also sells lifetime traffic information for 50$ on their website. Maybe some devices have to be activated before traffic information works?

Anyways. I received the device yesterday and was eager to try it. That’s what I did on my way home last night. It was very simple to install. In fact, nothing special has to be done. The lighter power cord must be plugged into the device and the car (the FM RDS receiver is part of that cord) and that’s it. When I launched the device, it took just a few seconds before I could see a little “traffic icon” on the maps.

Pressing on that icon revealed two types of traffic information. I took a picture (shown below) of the traffic situation last night at around 7pm in Ottawa. As we can see, there was heavy traffic on the main highway in Ottawa… and that was no surprise to me… it was perfect timing for my experiment: hockey night! And every time its the same thing: the highway gets jammed at the “Scotiabank Place”. So that’s the red segment on the map here.

The other traffic display shows a list of the various problem zones. This is shown on the second photo I took:

IMG_3199.JPG.png

So very positive experience for me. I’m impressed. It works well and is very easy to use. The next step will be to see how real-time navigation and re-routing works considering the traffic. In the meantime, I guess canadians will want a new Garmin for Christmas because they certainly understand that traffic is a major enhancement on a GPS device.

If you wonder where exactly the service is available, have a look at this page on the Navteq website. A quick scan over the list shows following regions: Hamilton-Burlington, Montreal-Laval, Oshawa-Whitby-Clarington, Ottawa-Gatineau, St. Catharines-Niagara Falls-Welland, Toronto-Mississauga and Vancouver-Surrey-Burnaby.

! UPDATE, WARNING: I was told that the service has not been officially launched yet. I guess that this means it may be unstable or could even be stopped anytime. Please consider this if you think of buying yourself a new Garmin for Christmas.

My eComm 2009 Talk Now Available on Video

December 2, 2009 in Applications, Consumer devices, Mobility by Administrator | No comments

I’m happy that my eComm talk finally got published online, 8 months after the conference. Events sponsors got published much earlier but hey, that’s fair for a professionally produced clip. I must admit that the AV infrastructure and the team at the event were excellent.

My talk was titled: “Mobile Digital Broadcasting: An Infrastructure for One-to-Many Converged Services”. We took this opportunity to officially release our Openmokast open source software framework. I was happy that my live demo worked as expected!



We had prepared a clip just in case the “demo effect” would hit on me on stage. Luckily this was not the case but the clip (which is more detailed than the live demo) can still be seen on our crcmmb Youtube Channel or here below:




And here are the slides I used for this presentation:

eComm was also for me a great occasion to meet with David Burges who presented his OpenBTS project live using the USRP as well. His demo looked incredibly like mine except he demonstrated live cell phone communications going through his GSM open source base station. There are lots of commonalities between our projects but essentially, both are about democratizing communications technologies to catalyze innovation.

Challenges for GPRS and 3G Radio

July 24, 2009 in Infrastructures, Mobility, Networked media, public broadcasting by Administrator | No comments

There is a nice post on the Public Radio Player (PRP) blog about some challenges for Internet radio when distributed over mobile wireless networks and some strategies used in the PRP.

“A dropped stream is the nemesis of any regular Public Radio Tuner user. Nothing is worse than being caught up in a great public radio program and have it suddenly cut out….”

Some challenges can be expected:

  • loss of signal while roaming from cell to cell. Networks are optimized for voice calls but not for data yet.
  • minimal bitrate like 32 kbps is desirable but connection is still not guaranteed and sound quality is no great
  • buffers have to be implemented in receiver to mitigate signal loss.

Results of a survey made by PC World suggest that 3G coverage may not be adequate for the delivery of sustained bitrates in major cities in USA. Like this table shows, networks speeds can be impressive but their reliability vary greatly so that live radio transmissions may be hard to achieve.

There is certainly a lot of room for experimentation here in this new area but I tend to believe that it could take a while before we see 3G replace true “physical layer” broadcast networks for live transmissions.

In-car Wi-Fi Internet Radio

June 24, 2009 in Consumer devices, Infrastructures, Mobility, Networked media by Administrator | 1 comment

As Internet radio appliances are becoming available, there is still the issue that they can’t be used in your car.

This could change thanks to so-called “in-car WiFi routers” which are designed to provide Internet access through 3G mobile telephony networks.

AutoNet Mobile offers such device and service combination:

we create a Wi-Fi hot spot that allows everyone in the car to connect multiple devices to the internet, in and around the car! it’s the next step in in-car entertainment and productvity. we make internet in your car easier than ever because we provide both the in-car router and the monthly service. our affordable monthly service plans start at only $29 per month.

This still represent an expensive proposition for radio though. One hour daily consumption of good quality Internet radio content could easily reach the 29$ 1Gb limit.

RDS Enabled Handhelds

April 24, 2009 in Applications, Infrastructures, Mobility, Services by Administrator | 1 comment

The current financial context is not optimal for deploying new broadcast networks. Some will tend to think twice on how to maximize the use of the current infrastructure.

Isn’t that the case with FM radio? Will it truly benefit from going digital?

One of the compromise I find attractive is starting to emerge: enabling mobile phone handsets to receive FM AND RDS. Such an effort led by GSS and Silicon Laboratiroes is reported here at RadioWorld.

GSS believes that cell phones that can receive FM without cumbersome headphone antennas will not only be more popular with consumers but can then put RDS capabilities into the hands of many more consumers, which in turn will better support the penetration of emergency alerting systems like its Alert FM.

App Stores Everywhere but in Broadcast Handsets

February 18, 2009 in Applications, Consumer devices, Mobility by Administrator | No comments

Application Stores are the big thing at the Mobile World Congress this week. Few stories here and here and here. While Apple’s AppStore and Google’s Android marketplace have been known for some time now, we hear that Nokia, Microsoft and RIM have similar plans.

As we mention in our recent EBU paper, new functionality in handsets will be done in software. This is quite new in the mobile world but we are definitely used to this principle with our personal computers. We buy software for them. That’s what makes them extremely flexible, evolutive and thus useful. This paradigm emerges on mobile phone platforms now because they are evolving as generic and powerful computing platforms too.

This trend was identified early on by Apple (as usual) who created the AppStore as part of the iPhone ecosystem. The AppStore creates a marketplace for developers and end-users. Developers offer their new creations through the system, typically for a small fee, while end-users shop for applications through iTunes. The whole process of purchasing, installing and removing applications has been streamlined to provide a “frictionless” end-user experience, apart from the few dollars that one has to leave on the table!

I believe that the key benefit from these new marketplaces for applications is innovation. A democratized marketplace for innovation.

Before, application innovation was limited to MNOs and key partners of the mobility value chain. Now, anybody can create new applications. New applications will come from the masses, like Google, Wikipedia, Flickr, Youtube came from new players and non-incumbents.

Also, with more open marketplaces comes increased competition. That is good for consumers. End-users are only one click away from competing applications.

And what if the competing application is free? Such platforms will make “free” and “pay for” applications equally accessible. Could this lead to the erosion of the software market? Many think so. In order to sell their apps, developers will have no other choice but to offer leading edge products with truly exclusive features.

What does this mean for broadcasting? At the moment not so much I guess. The perspective is attractive though. What if moving from DAB to DAB+ could simply be achieved through a new software app. A broadcaster would announce the move and asks its listeners to go buy the 2$ piece of software on the app store. In exchange, end users get more channels. Click, pay, download, … voila! What if all new broadcast applications could be offered this way? EPG, Slideshow, TPEG traffic overlay for google maps,… and so on. In fact, we don’t know what the mobile broadcast applications of the future will be. But we know it will be in software. We just need broadcast receivers in those handsets.

Radio on Mobile Devices

February 15, 2009 in Industry, Infrastructures, Mobility by Administrator | No comments

Mobility and radio go hand in hand. James Cridland reports on a current positive trend:

“RAJAR’s recent figures were upbeat about listening to the radio on mobile devices. (They only monitor ‘listening via mobile phones’, despite many MP3 players also having FM radios built-in)”

Competing business models between mobile network operators and broadcasters prevent broadcast receivers from being integrated into mobile phones. At CRC, we work on a project that would allow broadcasters to sponsor and eventually develop their own receivers. The project is called Openmokast. We published our thoughts and results about this in a paper released as part of last month’s EBU Technical Review.

We suggest that innovation in mobile digital broadcasting (including digital radio) will happen with the event of open source platforms like Android and Openmoko.

Canada to Go All GSM

October 15, 2008 in Consumer devices, Industry, Infrastructures, Mobility by Administrator | No comments

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?

Videobomb

February 15, 2006 in Applications, Mobility by Administrator | No comments

Videobomb is a good example of the power of adding "social" features to video clips viewing services. Here, viewers "bomb" (vote) for clips of their choice:

Video Bomb filters up the hottest videos on the Internet: people submit links to the ‘Incoming!’ page and you bomb the best ones. If a video gets a lot of bombs quickly, it makes it to the front page.

Last week I spent at least one hour watching front page entries and I must admit I was laughing to tears. After that I called my friend (over Skype) and I told him to have a look at the best clips. As I expected, I heard him laugh a lot but I was missing the possiblity for us to view the clips simultaneously.

It becomes also clear with such a service that It will be essential to be able to "bomb" media content on-the-go somehow with the portable media player. This information could be uploaded to the network at the next PC sync. opportunity.

Satellite services to mobile phones

February 8, 2006 in Applications, Infrastructures, Mobility by Administrator | No comments

After radio, with Sirius and XM, PanAmSat plans to provide mobile video to consumers:
 
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.
 
This approach could be similar to the Korean DMB-S system.

IP Wireless and TDtv

January 31, 2006 in Applications, Industry, Infrastructures, Mobility by Administrator | No comments

The 3GSM world congress is coming in two weeks and that is probably the reason why we see so many press releases these days. Mobile TV will definitely be a hot topic this year.
 
Well recently, the TDtv technolgy was anounced:
 
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).
 
TDtv is a Sprint Nextel effort to keep Mobile TV within the 3G ecosystem. It is based on the multimedia broadcast and multicast service (MBMS) specification.
 

A new mobile TV alliance

January 23, 2006 in Applications, Industry, Mobility, Services by Administrator | No comments

Nokia announced the following today:
 

… Other firms in the alliance include Intel Corp., Motorola, Texas Instruments and Modeo, owned by Crown Castle International Corp., it said in a statement. The tie-up, called the Mobile DTV Alliance, aims to encourage open standards for TV broadcasts to mobiles, focusing on the North American market.

DVB-H (Digital Video Broadcasting – Handheld) technology bypasses mobile networks and broadcasts directly to handsets from TV masts, allowing millions of phone users to access the service at the same time.

This seems to build a united DVB-H front against Qualcomm’s MediaFLO in the US.
 

Motorola iRadio

January 16, 2006 in Mobility, Services by Administrator | 1 comment

This Reuters.com story tells us a little bit about the new iRadio service by Motorola. After looking at the iRadio website , I would summarize the whole story with this:
 
iRadio = podcasting by Motorola
 
Althoug the name is not ideal (somewhat confusing because it is absolutely not radio) I prefer it to Podcasting. Podcasting is a direct reference to the iPod and I find it sad that we’re stuck with a product-based terminology for such an important innovation. Nevertheless, the iPod, in conjunction with iTunes, is probably the best platform for podcasting.
 
After launching the Rokr cellular phone last September with Apple, Motorola introduces the new Rokr E2 that will receive iRadio services.

Mobile TV at CES 2006

January 10, 2006 in Infrastructures, Mobility, Services by Administrator | No comments

Mobile TV made the news last week at CES 2006 with announcments and product demonstrations. From now on, one of the two major ventures will be called Modeo (formerly known as Crown Castle Mobile Media) while the other one has been known under the name of  MediaFLO (Qualcomm) for a while now.
 
Both services will be very similar with, of course, some variations. This paper  at C|Net provides a very good comparative overview of the two technologies.
 
This Nokia device was presented running a Modeo demo last week. Here is another device by Motorola .

WiBro demo in Turin

December 22, 2005 in Infrastructures, Mobility by Administrator | No comments

Telecom Italia and Samsung will demonstrate the WiBro system (the Corean flavor of WiMax) at the 2006 winter olympics in Turin, Italy. After that, we will have the DMB system in demonstration in Germany, presenting the FiFa Worldcup 2006. We have an interesting year for broadcasting ahead of us.
 

411-Song

December 21, 2005 in Applications, Mobility by Administrator | 2 comments

Another new cell phone pay service in the US. It identifies the song that you’re currently hearing on radio… or anywhere else actually. Simple system:
 
“How many times have you heard a song and wished you knew who it was or wished you could get it before you forget it? Now you can, just call (866) 411-SONG, here’s how: * Hear a song you love; * Call (866) 411-SONG; * Wait for the beep and hold your cell near the music for just 15 seconds; * We identify the song and send you a text with all the song info (artist and song name) and a link to GET it.”
 
See the demo. At 3.99$ a month it’s not cheap though.
 
 

Mobile WiMAX Standard Finalized

December 20, 2005 in Infrastructures, Mobility by Administrator | No comments

I’m a little bit late on the news but I just noticed that the IEEE 802.16e has been finalized two weeks ago. As Om Malik puts it, that was the easiest part:
 
… now companies have to get onboard with the concept, start developing silicon and equipment. But more than that, money has to be found, to essentially (and eventually) replicate the cellular mobile infrastructure. It is going to be a very costly and long drawn out process. It might be easy to get caught in the euphoria surrounding the news, but we all need to take a deep breath and get prepared for a long haul.
 
The Register has a short story about this announcement.
 
I have not had the time to look into the specification but WiMAX could be seen as a threat to mobile broadcasting systems such as DMB, DVB-H or MediaFLO. And since WiMAX’s mother tongue is “Internet”,  it could be seen as the long awaited and open platform for disruptive mobile applications. Broadcasting 2.0 believers will have to dig into WiMAX broadcasting capabilities.
 

MPEG LASeR Standard

December 15, 2005 in Media formats, Mobility by Administrator | 1 comment

LASeR is a recent open standardization effort targeting “rich media” mobile multimedia platforms. As such, it could become a component of the broadcasting DAB and DVB-H consumer devices. 
Here is an excerpt from the technical white paper:
The inherent content and binary encoding structure makes it inappropriate for the mobile. Instead of compromising on the technology performances, MPEG reached the conclusion that an optimum between feature richness/compression efficiency and device constraints needed to be found and decided to create a new standard for Rich Media for constrained devices.
