Hi all,
as promised, here is my report on DRM at IFA, which I went to last Friday, the first day of the exhibition. I met Simone there and she kindly agreed to host my pictures on her website. To look at them, just click on the links. Copyright is retained on all the pictures. Links to this forum post are granted.
First DRM booth - broadcasters and Radioscape
DRM was present at two booths, here is a picture of the booth (http://www.stoepplernet.de/drm/ifa05/DRM_booth.jpg) that had been organized by broadcasters and Radioscape. There, five different receivers were on display, of which only three could be tested, the others were just displayed in plexiglass boxes.
Most of the receivers shown at this booth contain the radioscape RS500 module (http://www.stoepplernet.de/drm/ifa05/RS500_1.jpg). A slightly different module (http://www.stoepplernet.de/drm/ifa05/RS500_2.jpg) (DAB + FM only?) with a somewhat modified layout and a few different chips was also shown. Here is another picture (http://www.stoepplernet.de/drm/ifa05/RS500_noscreen.jpg) showing the module with the RF shield and a few other parts removed and this picture shows an evaluation board (http://www.stoepplernet.de/drm/ifa05/RS500_protoboard.jpg) for this module.
Morphy Richards receiver
Another receiver, that could not be tested at this booth because it was only displayed resting in a transparent box, was labelled Morphy Richards (http://www.stoepplernet.de/drm/ifa05/Morphy_Richards1.jpg). Have a look at its display and control buttons here (http://www.stoepplernet.de/drm/ifa05/Morphy_Richards2.jpg). Here is another picture (http://www.stoepplernet.de/drm/ifa05/Morphy_Richards3.jpg) of this receiver.
Roberts RD-20 receiver
Another receiver (http://www.stoepplernet.de/drm/ifa05/roberts_3_side.jpg), bearing the Roberts label, was also on display. More on this receiver further down.
Sangean/Roberts receivers
Now to the most interesting sets that could be touched and played with.
Two sets, one bearing the Sangean label and one bearing the Roberts label, were shown. The set branded with the Roberts label will be sold only in the UK, whereas the Sangean branded set will be marketed world-wide. Both are identical and are manufactured by Sangean. Have a look at the receivers front side (http://www.stoepplernet.de/drm/ifa05/Sangean_front.jpg), its display (http://www.stoepplernet.de/drm/ifa05/Sangean_disp.jpg) (showing page 4 of engineering mode), its left side (http://www.stoepplernet.de/drm/ifa05/Sangean_connectors.jpg) with input and output connectors, its right side (http://www.stoepplernet.de/drm/ifa05/Sangean_knobs.jpg) with all the knobs and its rear side (http://www.stoepplernet.de/drm/ifa05/Sangean_rear.jpg).
This receiver has the following features:
- receives AM, FM, DAB, DRM
- receives AM double sideband with a fixed IF bandwidth, does not receive SSB
- has a built-in ferrite antenna
- receives FM stereo
- runs on external power (6.5 V, 1.5 A) or from 4 D-cells sitting in a battery compartment at the lower rear side, which will allow continuous reception for about 6 hours, however power consumption is expected to be halved during further development
- will not run from 4 NiCD or NiMH cells inserted in place of standard batteries because then, the voltage available will be too low
- has a digital audio interface
- has a USB interface through which it can be controlled and have its internal software upgraded from a PC
- has a slot for an SD-card, onto which received content can be stored (DAB as mpeg, DRM as AAC without conversion) and from which content can be played back.
- will play MP3-files stored on the SD-card
- supports DRM in narrow and wide (20 kHz) bandwidths
- when receiving 20 kHz wide DRM transmissions, SBR is disabled because otherwise, the processing power required would exceed that of the built-in DSP.
I was told that, at the moment, one does not intend to supply the receiver with control and record/playback software for the PC, this might however be available as an additional item at extra cost. Digital Rights Management features seem to have been already incorporated in the receiver's firmware, so not every content recorded off the air might be played back from the SD card on another device. The receiver itself will however allow to play back the content after recording even if it should be protected by Digital Rights Management features.
Expected price for the receiver will be about 200 to 250 EUR. The total quantity available in shops at Christmas 2005 should be in the order of about 10,000 units.
A telescopic aerial can be mounted directly to the receiver's antenna connector.
The receiver had an "engineering" menu showing a lot of details about the received signal, this menu will most likely not be available in the resale version.
The receiver's audio sounded quite well on headphones, however with all the high-volume background noise from other exhibition booths, the audio quality of the built-in speaker could not be judged. There were some initial problems with antenna cabling, this picture (http://www.stoepplernet.de/drm/ifa05/lx1nw_connector_repair.jpg) shows our forum member lx1nw (from BCE/RTL) mounting a new F-connector onto one of the antenna cables.
Panasonic prototype receiver
Also shown and demonstrated was the prototype of a Panasonic car receiver (http://www.stoepplernet.de/drm/ifa05/Panasonic_proto.jpg). This receiver seemed to be an engineering model, since the control buttons did not mention DRM in any way.
DRM in a car
A car, which had been fitted with a DRM receiver, was also demonstrated (http://www.stoepplernet.de/drm/ifa05/DRM_in_car.jpg). I don't know, whether the receiver built into the car is also using the RS500 module.
Second DRM booth - DRM consortium
At a second DRM booth, organized by the DRM consortium, transmitter as well as test equipment and again receivers were demonstrated.
Roberts RD-20 receiver - more pictures
Here, I took pictures of the Roberts receiver (http://www.stoepplernet.de/drm/ifa05/roberts_2.jpg) and a close-up (http://www.stoepplernet.de/drm/ifa05/roberts_2_top.jpg) showing display and controls. This receiver does not have an SD card slot, only the receiver's internal memory can be used to record and replay audio content.
DRM2008
The new Himalaya receiver, labelled DRM2008 (http://www.stoepplernet.de/drm/ifa05/DRM2008_front.jpg) was also demonstrated.
Have a look at its rear side (http://www.stoepplernet.de/drm/ifa05/DRM2008_rear.jpg) and at its display (http://www.stoepplernet.de/drm/ifa05/DRM_2008_display.jpg). I tried to operate the set but it was either locked or the controls were not wired. The lowest line on the display showed scrolling text, here is another picture (http://www.stoepplernet.de/drm/ifa05/DRM2008_disp.jpg).
Blaupunkt/Bosch prototype receiver
Blaupunkt (http://www.stoepplernet.de/drm/ifa05/Blaupunkt_1.jpg), a leading german manufacturer of car receivers was demonstrating a prototype receiver (http://www.stoepplernet.de/drm/ifa05/Blaupunkt_2.jpg). This receiver is limited to an upper frequency of 16 MHz in DRM and AM modes. Multimedia information received by the radio is transmitted via WLAN to a PDA on which multimedia messages being "broadcasted" (sic!) can be displayed (http://www.stoepplernet.de/drm/ifa05/Blaupunkt_PDA.jpg) in portrait or in landscape mode (http://www.stoepplernet.de/drm/ifa05/Multimedia_wlan_pda.jpg).
Fraunhofer
Fraunhofer were showing a prototype board of which I took a picture (http://www.stoepplernet.de/drm/ifa05/Fraunhofer_protoboard.jpg) but about which I don't know anything except that it uses a low power chipset from Analog Devices. In addition to the well known DWT, Fraunhofer were also showing their newsbox (http://www.stoepplernet.de/drm/ifa05/newsbox.jpg).
That's all, thanks for reading. If you want to reply to this post then please do not quote the whole content of this report in your reply, thanks!
Edit: I have made a few corrections with regard to text and bad links. Have a look at the posts below for further information and corrections.
