Video Over Shortwave Demonstrated at IBC

(Source: TVB – Television Broadcast)

AMSTERDAM: Transmission of video over the shortwave radio topology is being demonstrated at IBC by Fraunhofer. The company rolled out “Diveemo,” a system delivers video via Digital Radio Mondiale, the MPEG-4-based broadcasting technology used in the AM radio band. It was demonstrated today at the convention with BBC content displayed on a NewStar DRM receiver, Fraunhofer said.

Operating at just 8 frames per second, Diveemo transmissions are not designed to compete with even standard analog television; instead, Diveemo is being positioned for large-area distribution of education and news programs where the video supplements an existing audio program.

Fraunhofer notes that shortwave transmission can reach from “100 to well over 5 million square kilometers depending on conditions and broadcast parameters. The service opens the door to a large range of unprecedented information and education services and is an ideal platform to reach audiences worldwide with a single DRM transmitter or an even more cost-efficient DRM single frequency network. Diveemo offers free-of-charge reception and is independent of gatekeeper and third-party providers like satellite and cable networks.”

The system is being demonstrated by Fraunhofer and Thomson Broadcast on their respective stands at IBC2010. Fraunhofer and Thomson, along with Chengdu NewStar Electronics, developed Diveemo. The service is being presented for standardization by ETSI, and can be implemented by any broadcaster using DRM30 or DRM+.

Video files are added to the Fraunhofer DRM ContentServer where they are converted to MPEG-4 and prepared for transmission. DRM+ is capable of devoting a larger amount of data to the video than DRM30, allowing for better video quality with DRM+. Diveemo complements existing data services within DRM30 and DRM+, including MOT Slideshow for still images and Journaline for text-based data services.– With Radio World

Radio St. Helena Day 2010 has been cancelled

Unfortunately, Radio St. Helena Day has been canceled for 2010. The following message was received last night from the Radio St. Helena crew:

RSH << RSD 2010 Cancelled >> 10 September 2010


Radio St. Helena sincerely regrets to have to inform radio listeners everywhere that Radio St. Helena Day 2010 has been cancelled .

This very difficult decision was necessary, due to severe technical problems with the shortwave antenna tower.

RSH is quite confident that RSD will be able to continue in 2011.

With best greetings,

Mit besten Gruessen,

Gary Walters Station Manager, Radio St. Helena

Grundig G8 Traveler II on sale at National Geographic

The National Geographic online store has a few Grundig radios on sale. Most notably, the Grundig G8 for $24.95.

The G8 is a great little shortwave receiver. I’m very impressed with the performance, especially for a $25 radio (normally, these sell at retailers for $50.00 US).

Features include:

  • Auto/manual tuning
  • Auto Tuning Storage (ATS) function (on FM, this will auto-populate memory slots with available stations)
  • Digital tuning with digital frequency readout (LCD)
  • Local timer setting + world timer settin
  • Sleep timer & alarm clock (either radio or buzzer
  • Snooze
  • Key lock function
  • 3.5 mm headphone output
  • DC jack – 6V
  • Comes with warranty, manual and a nice travel case

Of course, with a radio in this price class, there are some compromises:

  • No single-side band.
  • There is muting between frequency changes, so while tuning you will notice a slight “chug” sound.
  • No manual gain control.
  • Speaker is small, though audio (as with many Grundig portables) is quite impressive.

At $25 US, this is a no-brainer. Pick up a G8 today as I have no idea how long this sale will last.
