Pci Tv Card 'LINK'
A TV tuner card is a kind of television tuner that allows television signals to be received by a computer. Most TV tuners also function as video capture cards, allowing them to record television programs onto a hard disk much like the digital video recorder (DVR) does.

The interfaces for TV tuner cards are most commonly either PCI bus expansion card or the newer PCI Express (PCIe) bus for many modern cards, but PCMCIA, ExpressCard, or USB devices also exist. In addition, some video cards double as TV tuners, notably the ATI All-In-Wonder series. The card contains a tuner and an analog-to-digital converter (collectively known as the analog front end) along with demodulation and interface logic. Some lower-end cards lack an onboard processor and, like a Winmodem, rely on the system's CPU for demodulation.
A hybrid tuner has one tuner that can be configured to act as an analog tuner or a digital tuner. Switching between the systems is fairly easy, but cannot be done immediately. The card operates as a digital tuner or an analog tuner until reconfigured.
This is similar to a hybrid tuner, except there are two separate tuners on the card. One can watch analog while recording digital, or vice versa. The card operates as an analog tuner and a digital tuner simultaneously. The advantages over two separate cards are cost and utilization of expansion slots in the computer. As many regions around the world convert from analog to digital broadcasts, these tuners are gaining popularity.
Like the analog cards, the Hybrid and Combo tuners can have specialized chips on the tuner card to perform the encoding, or leave this task to the CPU. The tuner cards with this 'hardware encoding' are generally thought of as being higher quality. Small USB tuner sticks have become more popular in 2006 and 2007 and are expected to increase in popularity. These small tuners generally do not have hardware encoding due to size and heat constraints.
While most TV tuners are limited to the radio frequencies and video formats used in the country of sale, many TV tuners used in computers use DSP, so a firmware upgrade is often all that's necessary to change the supported video format. Many newer TV tuners have flash memory big enough to hold the firmware sets for decoding several different video formats, making it possible to use the tuner in many countries without having to flash the firmware. However, while it is generally possible to flash a card from one analog format to another due to the similarities, it is generally not possible to flash a card from one digital format to another due to differences in decode logic necessary.
External TV tuner card attachments are available for mobile phone handsets like the iPhone, for watching mobile TV, via TV stations on 1seg in Japan (SoftBank), and for soon for the proprietary subscription-based MediaFLO in the U.S. (Qualcomm). There is also a "converter" for watching DVB-H in Europe and elsewhere via WiFi streaming video (PacketVideo).
Video capture cards are a class of video capture devices designed to plug directly into expansion slots in personal computers and servers. Models from many manufacturers are available; all comply with one of the popular host bus standards including PCI, newer PCI Express (PCIe) or AGP bus interfaces.
These cards typically include one or more software drivers to expose the cards' features, via various operating systems, to software applications that further process the video for specific purposes. As a class, the cards are used to capture baseband analog composite video, S-Video, and, in models equipped with tuners, RF modulated video. Some specialized cards support digital video via digital video delivery standards including Serial Digital Interface (SDI) and, more recently, the emerging HDMI standard. These models often support both standard definition (SD) and high definition (HD) variants.
While most PCI and PCI-Express capture devices are dedicated to that purpose, AGP capture devices are usually included with the graphics adapted on the board as an all-in-one package. Unlike video editing cards, these cards tend to not have dedicated hardware for processing video beyond the analog-to-digital conversion. Most, but not all, video capture cards also support one or more channels of audio. New technologies allow PCI-Express and HD-SDI to be implemented on video capture cards at lower costs than before.
There are many applications for video capture cards like EasyCap including converting a live analog source into some type of analog or digital media, (such as a VHS tape to a DVD), archiving, video editing, scheduled recording (such as a DVR), television tuning, or video surveillance. The cards may have significantly different designs to optimally support each of these functions. Capture cards can be used for recording a video game longplay (LP) so gamers can make walkthrough gameplay videos.
One of the most popular applications for video capture cards is to capture video and audio for live Internet video streaming. The live stream can also be simultaneously archived and formatted for video on demand. The capture cards used for this purpose are typically purchased, installed, and configured in host PC systems by hobbyists or systems integrators. Some care is required to select suitable host systems for video encoding, particularly HD applications which are more affected by CPU performance, number of CPU cores, and certain motherboard characteristics that heavily influence capture performance.
A video capture card allows its user to record media content from a variety of devices, including cameras, consoles, TVs, and computers. In many cases, the technology is used to record a live feed for playback and editing later. In some cases, they can be also used in conjunction with computer software to manage and live stream content to another device or over the internet via streaming services such as Twitch or YouTube.
Capture cards ultimately let you outsource the performance hit of live streaming or recording video content to the device itself, so if you were previously using your computer to record or livestream, your performance will naturally be improved when offloading to a capture card instead. Regardless, many capture cards still come with system requirements as, like any process, they have some affect on your PC performance when used. As long as your machine meets the mark set by the device, you should be fine!
The following table lists the confirmed working DVB-T PCI cards and provides a brief summary of their features and components. If you need more technical information on a device, have a look at its specific wiki article.
Revision 2 of this card has just been released (image). The new card uses a DIBCOM tuner and modulator and does not work under the current driver.The linuxTV drivers are now updated, the revision two works beautifully. The changes do not yet seem to be merged with the Linux kernel (2.6.27), the link above should help you install the drivers. The Rev 2 card may not work properly with older kernels such as 2.6.22 (AMD 780G chipsets, USB disconnects), even using the latest linuxTV drivers. The following link also has some useful information: =616103
So please refer to DTV2000DS for extra info.Dual DVB-T tuners, also known as PEAK DVB-T Dual tuner PCI (221544AGPK)Working as single tuner card (at least) on 2008-06-05 anttip/af9015-mxl500x-copy-fw/ crope/v4l-dvb/af9015/af9015_firmware_cutter/firmware_filesRef =linux-dvb&m=121268349100641&w=2A single tuner variant (PC-160-T) is now also supported.

What is the design limitation they refer to, and does it only apply to PCI-E graphics card or will any PCI-E card make the HDMI port stop working? I would prefer to continue using the HDMI connector because I don't then need a separate connection for sound.
This is probably due to a limited mastery of English. It's common for on-board video to turn itself off when a video card is inserted into the PCI-e slot. This made sense, because that videocard is usually far more powerful (however, modern computers may keep the internal video enabled to drive two monitors in that configuration).
I am now almost certain that this the same problem as in the linked question. If you look at section 220.127.116.11 in the documentation for a board using the the G45 chipset it appears that the HDMI port will work with a non-Video x1 PCI-E card. Fortunately the card I want to use is PCI-E x1 so it will be fine. A bigger card will cause the HDMI port not to work.
These PCI Express TV tuner cards from TBS Technologies offer great picture quality and allow you to watch/record up to two or four terrestrial or satellite TV channels simultaneously.
We are pleased to offer the TV tuner cards which Media Center fans have been longing for. These latest PCI Express cards from South-Korean DVB experts TBS Technologies offer the ability to receive standard and high definition TV channels and come in a choice of terrestrial or satellite models, along with quad or dual tuners on one card (see notes below for recommended software).
Please note that for the satellite (DVB-S2) models, it is advisable to connect a power cable to the card in order to ensure that it will receive enough power, because some motherboards cannot supply a high enough current through their PCI Express slots. The TBS 6904 card comes with an adapter which can be connected to a standard spare Molex 4-pin power connector.
The TBS Satellite cards are fully compatible with Freesat and Freesat HD broadcasts, in addition of course to many other DVB-S and DVB-S2 satellite broadcasts depending on which satellite the dish and LNB are aligned to.
