About external tv tuner

Type of external TV tuners

An external TV tuner is a device that adds capabilities to receive television signals to a computer or other display device. It does this by converting the signal into a format that can be displayed and recorded. An external TV tuner often connects via USB or another interface and may have features such as recording, pausing, and rewinding live TV.

External TV tuners come in various types, each capable of tuning television signals from different sources. The following list highlights the significant kinds of external TV tuners:

  • Analog tuner: An analog tuner receives and decodes traditional analog cable or over-the-air broadcasts. These signals are often broadcasted in NTSC, PAL, or SECAM formats, depending on the region's standard. However, many tuners now consider obsolete receivers since most countries are transitioning to digital broadcasting.
  • Digital tuner: A digital tuner uses a USB capture card to record TV programs digitally. It receives broadcasts in the form of a digital signal that can be in DVB, ATSC, or QAM formats. Digital tuners provide better picture and sound quality than their analog counterparts. They also come with features such as multiple tuning capabilities, which allow them to tune different channels simultaneously and record them.
  • Satellite tuner: A satellite tuner retrieves signals from a direct broadcast satellite service. It decodes the signal using systems such as DSS, DVB-S, or DVB-S2. Satellite tuners provide access to many high-definition channels that may not be available via cable or over-the-air broadcasts.
  • Cable tuner: A cable tuner retrieves signals from a cable service. It uses technologies like NTSC, QAM, or clear QAM to tune into channels. Cable tuners provide access to a wide range of channels, including high-definition broadcasts, which require an additional cable box or decoder.
  • Hybrid tuner: Hybrid tuners combine digital and analog capabilities in one device. They work well to receive and decode both types of signals, making them suitable for users in areas where both kinds of broadcasts are still available. Hybrid tuners often have advanced features like multiple tuners and high-definition support.
  • Internal TV tuner: Internal TV tuners are expansion cards installed inside a computer. These cards have tuners that can receive and decode television signals. Internal tuners connect to the system via PCIe slots and are often equipped with an antenna port for connecting antennas or cable lines. They turn a computer into a TV by using a TV card or other compatible software to display the tuned signals.
  • USB TV tuner: USB TV tuners are small devices that plug into a computer's USB port. They have built-in televisions that can receive and decode signals into a format that can be recorded or displayed on a screen. USB tuners are portable and offer an easy way to add TV tuning capabilities to a laptop or desktop computer.

Functions and Features

Internal and external tuners for TVs enjoy several unique features. Ideally, the features of an external TV tuner will vary depending on the brand, manufacturer, model, and buyer preferences. The most common features among external TV tuners include;

  • Multiple device connection: Some external tuners come with HDMI input ports enabling them to connect to media players, game consoles, Blu-ray players, and streaming devices. This feature expands the content options into the watch via the external TV tuner.
  • Guide system: A user friendly program guide system is an important feature of external tuners. It enables easy navigation of channels and programs as well as access to EPGe. The guide system also provides information about scheduled programming.
  • Audio output: Most external TV tuners have audio outputs. For instance, the digital audio output, usually coaxial or optical can be linked to a home theater system to enhance a listener's audio experience.
  • Timer functions: Many external TV tuners have timers. They allow users to set a timer and fall asleep while watching TV or schedule turns to wake up early in the morning to watch news.
  • Picture-in-picture: The picture-in-picture feature allows external TV tuners to display a highlighted miniature channel on one side of the screen while the main content is displayed on the other side. This allows viewers to switch to a highlighted channel easily.
  • Remote control: External tuners normally come with remote control(s) that are easy to use to navigate through channels, adjust volume, and settings among other important adjustments.
  • User menu settings: External tuners usually come with a settings menu that allows customization of various settings such as parental controls, audio settings, and picture settings.
  • Digital recording: Some external TV tuners have a digital recording feature that allows viewers to record content and play it back later.

Use of External TV Tuners

An external TV tuner can be used in several ways;

  • Connecting an old TV to Cable or Satellite

    A TV that does not have a built-in digital tuner can still receive cable, satellite, and over-the-air signals with an external tuner. This allows the use of an older TV without a digital tuner to watch cable and satellite channels or to benefit from digital broadcasts after the transition from analog to digital broadcasting.

  • Picture and Video Streaming and Gaming Sound Enhancement

    An external tuner can enhance picture and video quality by upscaling and applying video correction. Some tuners have features like high dynamic range (HDR) that improve the quality of compatible video content. External TV tuners also allow gaming with high-quality video and surround sound. Connecting a gaming console to the tuner will enable the gaming console to output high-resolution video and multi-channel audio to the TV.

  • Recording Shows

    An external tuner also allows the user to record shows from a cable or satellite signal to a hard drive. This enables users to have a digital video recorder (DVR) functionality for viewing and recording TV programming. Some tuners also offer scheduling recording of videos to be recorded even if the user is not present at the time of the show.

  • Using Multiple TVs

    Another use of the TV tuner is to use it to have multiple TVs showing different channels simultaneously. This can be achieved by having multiple tuners connected to different TVs. Multiple tuners will allow each TV to display a different channel or input without the need for a cable or satellite box for each TV.

  • Home Office or Workspace Entertainment

    The external TV tuner can be used in home offices or workspaces. Instead of a separate office monitor and TV, the TV can serve both purposes. An external tuner makes it easy to watch TV while working on the computer or doing office tasks. Tuning into music channels or streaming content allows for keeping up with news, sports, and entertainment while working. This is more space-saving and convenient than having two separate screens.

  • Portability

    Some tuners are portable, so they can be taken where they are needed most. Portability allows an external tuner to be moved easily. It can be used to watch TV and change rooms in the house. If a TV is broken or goes in for repairs, the tuner can be taken and set up on a working TV. Some tuners are small enough to be taken to hotels and used with the TV in the room when traveling.

How to Choose external TV tuners

When looking to buy a tuner for a TV, various aspects should be considered to ensure that it meets the required specifications and preferences. Below are a few factors that a buyer should consider when purchasing a TV tuner.
