Kworld PE355-2T with major chip markings.

A DVB-T PCIe card from KWorld.

Support is currently blocked on development of the NXP SAA716x PCI-E bridge chip driver.


Connections on this device are simple.

  • PCI-e interface
  • Inputs: Antenna (Beiling Lee)
  • Usually bundled with a USB IR receiver and remote. The key mappings of the remote are windows centric, including using ALT-F2 for one of the keys.

Making it Work

This card is not supported. Further work is blocked on development of the SAA716x driver.


This card may require firmware. There is no reason to assume that standard firmwares currently available for the tuners and demodulators will not work.


Users wanting to attempt can try the experimental drivers for the SAA716x.

Remote Control Support

The bundled USB ir device and remote work as a /dev/input keyboard device. Several of the mappings are not usable in linux.
