Livio NPR Radio

November 26, 2009 in Consumer devices, Industry, Networked media, Services, public broadcasting by Administrator | 1 comment

The NPR Radio by Livio_ NPR Shop.pngLivio announces its NPR branded Internet Radio Appliance. This device will offer a specialized menu to easily access NPR’s 800 radio stations. Of course, all other Internet radio stations can be accessed as well.

Are such “specialized” devices the future? We’ve seen the WikiReader recently which only does one thing: portable unconnected access to Wikipedia.

I don’t know but it makes great sense to me. I would love to see a CBC / Radio-Canada device like this. CBC/RC have great Internet offerings but they tend to “capture” the audience into their branded web portals. Because of this, many CBC/RC Internet radio streams are not accessible through Internet appliances other than full fledged PC’s. A branded device seems to be a good compromise to escape the PC prison.

Another very promising effect of this device is that it will help fund NPR’s programming since they will collect a portion of the proceeds. What an original way to fund public broadcasters!

   

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.

FLOSS Media Centers

Media centers could become the main interfaces to media content in home networks . The Telematics Freedom Foundation recently released a short report on Free Libre Open Source Software (FLOSS) options here. The report compares features of projects like XBMC, MythTV, freevo, Moovida (Elisa) and so on.

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.
