'''KWorld appears to have exited the TV tuner business some time in 2016. This was their last ATSC model being sold.'''
An [[ATSC]] [[ATSC USB Devices|USB 2.0 device]] from [[KWorld]].


An [[ATSC]] [[ATSC USB Devices|USB 2.0 device]] from [[KWorld]].
It is supported under Linux.


There are 3 versions of this device - each has a different VID:UID:
[[Wikipedia:Caveat_emptor]! There is a different variant of the same named device/model exists, containing different hardware components and is presently not supported. [http://www.mail-archive.com/linux-media@vger.kernel.org/msg38402.html] [http://www.mail-archive.com/linux-media@vger.kernel.org/msg38617.html]
*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==
==Overview/Features==
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.

KWorld UB435-Q USB ATSC TV Stick

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).
  • Dolby Digital AC3 Audio Output.

Components Used

  • NXP TDA18271HD/C2 tuner
  • LG LGDT3304 digital demodulator
  • Empia EM2870 USB bridge

Identification

Looks and is identical to the older ATSC 340U, but with different coloured packaging, and uses a newer revision (C2) of the tuner. [1] [2] Internal PCB is stamped ATSC_340U Ver:B

UB435-Q V2 Overview/Features

Components Used

  • NXP TDA18271HD/C2 tuner
  • LG LGDT3305 digital demodulator (neatly stamped "7th Generation VSB/QAM Receiver")
  • Empia EM2874B USB bridge (?)

Identification

Looks like original version. Label on back with UPC code has V2 added to name.
