Example Image: Add a good overall image of what the device looks like here and perhaps a very brief description

An OEM single-board-computer for the basis of set-top-boxes, integrated TVs and integrated TVs with PVR and/or DVD playback capabilities. The pcb forms the basis of a great number of products on the market today, including from UMC (Universal Media Corporation), Technika, Murphy, Swisstech, JMB, Logik, Teac, Vision Plus and Zhejiang Belson Technology Co. (China), Ltd. (Bereson). The PCB is thought to be designed and marketted by CVT (Guangzhou Shiyuan Electronics Co. Ltd of China). The PCB is manufactured by Guangzhou Suntech Print Circuit Board Ltd, which appears to be a division of CVT.

The CVT boards are not supported under Linux although many of the individual devices are.


Boards in this range

Boards in this range include:

  • LT712B - Euro Analogue/Digital with composite, component, analogue audio and coax SPDIF in and CI interface
  • LT712C - Euro Analogue/Digital with component in and CI interface
  • LT715X - Euro Analogue/Digital with CI interface and 2x9w
  • LT716X

Overview/Features

The boards are available in various hardware configurations.

  • Optional CI Interface
  • Inputs: HDMI, PC (HD15), Scart, S-Video, PC Audio (3.5mm jack), Component/S-Video Audio (3.5mm Jack)
  • Input Options of Composite + Audio L&R in; or Component Video (YPbPr); or both (various sub-models)

Other Images

Use the included code to insert other images if necessary. Add as many high resolution pictures as you can i.e the card, the original box, the remote and, when uploading the files to the wiki, give them detailed specific names. Note: only use images taken by yourself or those 3rd party images for which you have received express written consent (such as from a vendor) that permits their usage. For example:

  • VideoMate DVB-T220 Box

    VideoMate DVB-T220 Box

  • VideoMate DVB-T220 Remote

    VideoMate DVB-T220 Remote

Identification

Provide here, for PCI/PCIe devices, the relevant output of lspci -vnn or, in the case of USB devices, lsusb -v . We're particularly interested in the subsystem ID's. To make a code block simply make the first character of each line a space. For example:

# lspci -vvvnn

Making it Work

Is it supported under Linux? Are there experimental drivers? Does it partially work or identify as another card? (if yes, add this information below)

Firmware

Is there any firmware specific information for this device? if so, list it here. If your device doesn't require a firmware, simply mention that this is the case.

Drivers

Provide the details of where the drivers and patches and necessary tools are available.

External Links

Provide a link to the vendor's product page here along with any other external link to information that is generally helpful in relation to the device. For example:


Finally, add anything else that you think might be relevant under an appropriate heading.

Very last thing is add a catergory. (Remove the nowiki tags). For example
