KWorld ATSC 110

Front view of ATSC 110

An ATSC PCI card from KWorld.

The ATSC 110 is supported under Linux (added to kernel 2.6.17).

Overview/Features

Note: There is also currently an ATSC 110 page in the v4l wiki that contains some other info, which will eventually be merged together with the contents of this page

The ATSC 110 (which KWorld also labels as Model No. VS-ATSC110R) is a dual RF input pci card that comes with a remote & IR-receiver. It supports both analog (NTSC) and Digital (8-VSB and 256-QAM) sources. It has A/V inputs.

Components Used

• Philips TUV1236D NIM
  • Infineon TUA6034 (tuner)
  • Philips TDA9887 (analog IF demodulator)
  • ATI Nxt2004 (digital demodulator for 8VSB & 256/64-QAM)
• Philips SAA7135 (A/V decoder & PCI bridge)
• ? KS007 (remote control)

Identification

The card has a PCI subsystem ID of 17de:7350. If your PCIID database is up to date, then the output of lspci -vvnn should be similar to:

0:09.0 Multimedia controller [Class 0480]: Philips Semiconductors SAA7133/SAA7135 Video Broadcast Decoder [1131:7133] (rev f0)

Making it Work

Firmware

This card requires a firmware file (dvb-fe-nxt2004.fw¹) for the demodulator, which can be obtained using the get_dvb_firmware perl script included in the kernel sources:

# cd /[kernel source directory]/Documentation/dvb/
# perl get_dvb_firmware nxt2004

Once the download is complete, place a copy of the firmware file in your /lib/firmware directory. (This directory may differ with some distros; consult your distro's documentation for the appropriate location).

Note 1: All devices that use the Nxt2004 demodulator are currently using a firmware version from the AVerMedia AVerTVHD MCE A180. As the firmware's code has not been discerned, it is unclear whether other firmware for the Nxt2004 (i.e. those provided by other devices) would have any affect on reception performance.

Sample kernel output

The card should be auto-recognized, and the relevant output from dmesg should be similar to:

saa7130/34: v4l2 driver version 0.2.14 loaded
ACPI: PCI Interrupt 0000:00:09.0[A] -> GSI 19 (level, low) -> IRQ 177

With the firmware properly loaded, the relevant output from dmesg should be similar to:

nxt200x: NXT2004 Detected
DVB: registering new adapter (saa7133[0]).
DVB: registering frontend 0 (Nextwave NXT200X VSB/QAM frontend)...

Remote control support

Perhaps if the identity of the mysterious KS007 IC were known then support for the remote control could finally be submitted for inclusion (as it stands, the existing patches available provide some support, but they are known to break remote control support on other devices). There is a chance that the unknown IC is an Atmel AT8P56S, which is apparently used on the Leadtek WinFast HDTV Cinema (see this thread & its continuation for further details as to the potential identification).

In any regards, the same same remote/sensor combination is found on some other devices such as

• KWorld DVB-T220 (analog and digital)
• MSI tv@anywhere (analog)
