KWorld appears to have exited the TV tuner business some time in 2016. This was their last ATSC model being sold.
An ATSC USB 2.0 device from KWorld.
There are 3 versions of this device - each has a different VID:UID:
- 1b80:a340 no version indicator - supported under Linux as of Kernel 2.6.3
- 1b80:e346 add V2 to name - supported under Linux as of kernel 3.13
- 1b80:e34c add V3 to name - supported under Linux as of Kernel 3.16.??
Note
The U-shaped clear plastic covering the USB-end of the stick (visible in the image above) interferes with the USB plug and makes it difficult to form a firm connection into a USB socket. For a solid connection this should be removed or sanded down.
As the stick is known to run somewhat warm, removing it, or the entire case, may be worthwhile.
Original version Overview/Features
- High speed USB2.0 Plug-and-Play interface for PC or Laptop.
- USB 2.0 Bus-powered (No power adaptor required).
- Supports up to 1920x1080i (HDTV).
- Supports Digital TV (ATSC 8VSB) and Digital Cable TV (unencrypted QAM).

Components Used
- NXP TDA18271HD/C2 tuner
- LG LGDT3304 digital demodulator
- Empia EM2870 USB bridge
Identification
