Introduction

Magicpro proHDTV Dual is a hybrid usb TV adapter supporting analog and DMB-TH digital TV broadcast reception for Hong Kong. The demodulator chip for DMB-TH is LGS8GL5.

Driver installation

The Linux driver for this device was achieved by reverse engineering to mimic the packets sent from the PC to the device as can be seen in the usb sniffer log in Windows. The v4l-dvb driver pack can be downloaded at the following link:

http://www.sendspace.com/file/z2t0il

This driver pack is based on a snapshot of v4l-dvb repository at around early Oct 2009. Currently (as of Nov 2009) it has been tested for kernel versions from 2.6.28 to 2.8.31 under Ubuntu 8.04 and 9.10, also Debian Lenny and Squeeze. Note that it also includes support for ASUS u3100 DMB-TH adapter.

Driver installation

1. Untar the downloaded file under a <v4l-dvb source directory>;

2. Under <v4l-dvb source directory>,
make distclean
make
make install
-- done! --

Following kernel modules are relevant to this device: lgs8gxx, dib7000p, dvb_usb,_cxusb, dib7000p, dibx000_common, dvb_usb, dib0070, dvb-core, tuner_mpdual.

3. Below is sample 'dmesg' output when the adapter is inserted into a usb port: 

 
[10.135102] dvb-usb: found a 'Conexant Magicpro HDTV Dual DMB-TH Stick' in warm state.
 
[10.651330] dvb-usb: will pass the complete MPEG2 transport stream to the software demuxer.
 
[10.651474] DVB: registering new adapter (Conexant Magicpro HDTV Dual DMB-TH Stick)
 
[10.907720] DVB: registering adapter 0 frontend 0 (Legend Silicon LGS8913/LGS8GXX DMB-TH)...
 
[11.696562] MP_HDTV_DUAL tuner: Attached at address 0x61
 
[11.697958] dvb-usb: Conexant Magicpro HDTV Dual DMB-TH Stick successfully initialized and connected.
 
[11.698000] usbcore: registered new interface driver dvb_usb_cxusb

Supported Software

  • dvbscan, tzap, dvbsnoop, dvbstream, dvbtraffic have been tested to work.
  • dvbtune works but the adapter is turned off after dvbtune exits. If the software that subsequently runs, e.g. dvbsnoop, does not turn on the adapter, then it would fail.
  • Using vlc for tuning, e.g. "vlc dvb:// :dvb-frequency=482000000 --programs=2", results in chopping video, so is regarded not working.
  • kaffeine as on Ubuntu 9.10 is able to successfully scan for all 11 TV channels (provided signal strength is OK).
  • gXine should be working.

Testing

dvbscan

Using an initial_scan.conf file with following content (actually it is district and even building dependend): 

 
T 482000000 8MHz AUTO AUTO QAM64 8k 1/32 NONE
 
T 586000000 8MHz AUTO AUTO QAM64 8k 1/32 NONE
 
T 602000000 8MHz AUTO AUTO QAM64 8k 1/32 NONE

A scan can be performed by 'scan initial_scan.conf' and a sample output is as follows:

live TV watching and recording example

  • On one terminal, run


tzap -c /etc/dvb/channels.conf "home"


It should produce output similar to: 

 $ tzap -c /etc/dvb/channels.conf "home"
 
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
 
reading channels from file '/etc/dvb/channels.conf'
 
tuning to 482000000 Hz

Keep it running and do not terminate it.

  • On another terminal, run one of followings for TV watching:
 
  dvbsnoop -s ts -tsraw -b | mplayer -vo x11 -
 
        or
 
  dvbsnoop -s ts -tsraw -b | xine -
 
        or
 
  dvbsnoop -s ts -tsraw -b | vlc fd://0
  • Or on another terminal, run following for recording:
 dvbsnoop -s ts -tsraw -b | vlc fd://0 --programs=11 -I dummy --sout file/ts:test.ts


where test.ts is the output file for recording.
