  • Wanted: Programmer who wants to play with DAB+ option

    I have been in talks with Realtek about getting a copy of their SDK for the Realtek 2832 chipset, which is Realteks All in one DVB-T, DAB+ and FM chip.

    Thanks to some very friendly people there, they have given me a copy of the SDK, which includes documentation on the module, together with a sample DAB program, and the source code for the DAB program (written in Visual C++ by the looks of things).

    So, I have a request.

    Currently there is one main thread for getting the Venice based chips running through a daughterboard, which is a pretty good system, however seems to have a few issues (Board creater no longer available, technical support issues). I'm not slagging it off at all, but I think that the Realtek system can be another option for people. It has one MASSIVE bonus in that there is no translation to analogue to send audio to the computer, it is done totally via the USB or PCI bus, and decoding is done by the computer itself.

    I have tested the module in my car, using ArcSoft TotalMedia running, with an external DVB-T antenna, and I get DAB+ signals as clear as a bell up to a tested 130km/h. Dropouts are non-existant, and using TotalMedia, I can scan for all DAB+ stations in around 15 seconds.

    The other upside to this system, is that you can pick up these cards for around $20 AUD for a single tuner PCI card, or around $40 AUD for the dual tuner PCI cards. USB models are around the same price.

    I am looking for a programmer who can take the SDK and sample program, and create a Centrafuse, and possibly a RideRunner plugin to get the DAB(+) and FM side of things working, and possibly even integrate the DVB-T portion of the chipset to get TV working as well.

    I am offering the copy of the SDK for the programmer, and I am also willing to purchase one or two USB or PCI based units to ship to the programmer to use for testing purposes.

    I would prefer the programmer to be based in an area that has DAB+ (Australia would be even better, and Perth, Australia would be outstanding!), to make testing easier, but if anyone else would be interested, please let me know.

    So does anyone want to have a play, and expand our options for radio's in our computers?

    If so, PM me, or reply to this thread, and I will see what I can do to help.

    Thanks all,

    Andrew

    Do you know the sensitivity figure of this radio? I cant seems to find anything about this very important data.

    I might buy one to try, Ive seen them go cheap on ebay, same chip just different brand, are they all the same? Do you have a list of USB stick that use the same chipset?

    Cheers

      I'm not too sure about the sensitivity, I can go back and ask the Realtek rep if he has a spec sheet for the chipset for you.

      I believe that as long as the chipset is the same, the design should be relatively the same. The PCI cards are basically the Realtek chipset mated to a PCI to USB host adapter, as the cards themselves show up on my system as a USB card, not a DVB-T or DAB+ card.

      I'll see if I can get a list together of the brands and cards that use this chipset!

      They have stated that the SDK is windows only, they haven't got one for Linux as well, just to give you an idea.

        Hi fella, I would be interested in coding this in to FreeICE if possible. Is it something like this - http://www.ebay.co.uk/itm/DVB-T-USB-...-/370539376081

        There only 10 here... If so I will get one ordered and have aplay (although I'm not to struck on it being white.. lol)

          Well I've ordered one today so I will let you know. I've not done c++ at all but if there's a DLL in there I should be able to communicate with it :-)

          thanks

            Yep, thats definitely one, it uses the Realtek 2832 U chipset, which is the same.

            See what you think of it when you get the unit, and fire me off a PM if you would like a link to the SDK. Getting it going on more front ends would be great!

              Will be watching this, don't have time right now but will need to figure out radio when I get a build started.

                  Interesting SDK

                  Just got hold of the SDK (thanks) and fired up DAB player (exe). Did a search of channels and it picked up all the channels - no UK options but found the Australia one worked as the frequencies are the same.

                  Currently downloading Microsoft Visual c++ (free) to have a play. Have used c# before but not c++ but should pick it up.

                  Don't really know how to make a plug in yet for Centrafuse but intially I'm looking to create a program and embed/overlay it instead. I've got an idea to replace the song name portion of Centrafuse with a DAB radio LCD style display. Will then need to map forward, reverse, scann etc buttons in Centrafuse to change channel. For example, the radio function of Centrafuse already has a display section and tune and channel buttons - these just need mapping (perhaps using autohotkey or perhaps via the amended SDK source program.

                  Was going to try the same with Blaze HDTV but program (or it might be the RTL2832U driver) is a bit buggy and doesn't play properly when resume from hibernation - I need to change the DTV source and sometimes the channel to get it to play. Amending the SDK source I can perhaps work around these bugs.

                  I know this is not the best way to go but it is something which I think I can get my head around. Initially I just want something functional and reliable. The aesthetics will come later.

                  What do you think?

                    Which USB stick did you try it on? there are a few out there that uses the realtek chip. I got one last week, same as the one CdRsKuLL bought (MobiTV) and I cant get the DAB working on Total Media 3.5. The TV work fine apart from a few glitches and it needing an external antenna.

                    Do you or chester have the link to the SDK? please PM me if its not possible to post the link here. I mainly need to test how it compare to the venice, once Im convinced Ill start playing with the SDK. Im pretty sure it would work for some but I think the stick I have bought (9.99 from ebay) is not sensitive enough for car use, I think it has a different RF chip...

                    Thanks

                        Andrew,

                        Do you have a model number of the receiver you have. Maybe CdR and I can work on it together when we get time.... (who know when that will be)

                          I use TotalMedia 3.5 for my DAB+ card, and find that it doesnt resume from hibernate, but I think this is a program issue, as it drops back to the TotalMedia menu on resume, rather than coming up still inside the radio module.

                          ibf, I have just PM'ed you the link to the SDK mate, looking forward to seeing how you go

                            The two units that I have are the Mygica T-188, which is a single tuner PCI based card using the 2832U chipset, and the Mygica T1800 (I think...I'll double check the model number when I get home and edit as required) which is a dual tuner PCI card using 2 of the 2832U chipsets, on a single antenna input.

                            Also, if you guys want to test out the version of Arcsoft TotalMedia 3.5 that Mygica bundle with their cards, the link is here:

                            http://www.mygica.com/download/d_dvbt.asp

                            Hint: for testing purposes....the product key may possibly be shown on that page inadvertently as well........

                              Cheers... I got it working now, with the supplied small antenna it was able to pick up about half of the available station in my area.

                              Its definately work looking into, its pretty good actually for its price, I see plugins for this.
