Broadcom Crystal HD is minipcie card dedicated to hardware video decoding.

This product has its usage on netbooks, especially on Atom without ion. Offloads the CPU and gives possibility to decode even 1080HD video.
Since for some weeks I have available fullHD terrestrial signal, i decided to buy this card and do some tests with Progdvb.
Hardware used:
Netbook Lenovo S10-3t (version with Atom N550, 2gb ram)
Graphics Intel GMA 3150
Tuner Avermedia A316 (DVB-T)
CrystalHD card in version BCM970015 (latest)
Software:
Windows 7 32bit Home Premium
Latest Progdvb
Latest drivers
Once the driver was installed the "Broadcom Decoder" appared in Codecs menu. I use EVR. Later check via Properties confirmed that codec was used properly and it works. Its properties also allow to change preferences of the codec, but default seems to work fine.
If you also change output color format from auto to unsupported mode, you have no possibility to open the codec properties, stream will fail and you have to reinstall the drivers with codec.
Available Demuxers:
Prog
ArcSoft
Microsoft
Cyberlink
Elecard
Most of them work. However Arcsoft cause the stream to hang.
Big fullHD monitor however shows that the image provided by the codec is not so flawless. Resolution seems to be downscaled, so the GPU and CPU is able to handle the stream smoothly. This was visible only when the codec was used in standard way. When I opened youtube, the image seemed to be of much higher quality.
As a result of using this device the CPU usage is 16-25 percent. Previously the battery of the netbook was able to play standard definition TV for 5,5 hours. I have to test now how long it will play with same signal when CPU is not handling the decoding...
some problems:
When selecting HD channel the application might stop responding
Video decoded with this device is somethimes choppy. Reason is unknown.
