Twinhan VP-1030A
Introduction
A DVB-S Budget PCI card by TwinHan Technology Co. Ltd
Overview
("DST-030") (dst)
features: fullts, CI unsupported
card driver: dvb-bt8xx
interface: PCI
PCI device id: 14f1:8804
PCI subsystem id: 1822:0001
Bridge: bt8xx
frontend 1: LG
frontend driver: dst
CI: unsupported by current LinuxTV drivers, supported only by vendor drivers for kernel 2.4.20
Notes: The frontends on these cards are hidden behind an ASIC - no need to know the full details.
The actual card type is determined by interrogating the onboard EEPROM.
The only frontend driver for this card is the dst module. The tuner component initialization routines are held in the ASIC in the form of firmware (not reloadable through software). The oldest card in the DVB-S family from Twinhan !
This card uses the bttv driver. Well supported by LinuxTV drivers.
The Common Interface is not directly accessible via the LinuxTV drivers, but CAM initialization commands can be achieved via the PCI card interface.
The card is believed to support almost all major CAM's. No separate initialization required for different CAM's, since all the initialization is done in the ASIC's firmware.
Analogue BT-848 or BT-878 based cards must be removed before use.
The tuner is very weak. You can't receive every channel, even when you use 2 meter dish. You can receive more channels when using Linux instead of Windows.
