Types of digital tuners (receivers) provided for in the design of the TV.

Such tuners are necessary for receiving digital TV broadcasts; for normal operation, the broadcast standard must match the type of tuner (with some exceptions, see below). Note that the receivers are also available as separate devices; however, it is easier (and often cheaper) to buy a TV with a built-in tuner of the desired format. In modern TV you can find terrestrial tuners DVB-T2, cable DVB-C and satellite DVB-S and DVB-S2, here are their main features:

— DVB-T2 (terrestrial). The main modern standard for digital broadcasting. Such broadcasting has a number of advantages over traditional analogue broadcasting: it allows higher resolution and multi-channel audio transmission, with better sound and picture quality, and this quality is fully preserved until the signal weakens to a critical level. However, in some countries digital terrestrial broadcasting is just being put into operation, so it will not hurt to check the availability of DVB-T2 coverage in your area.

— DVB-C (cable). The main modern standard for digital broadcasting in cable networks. Despite the advent of the more advanced DVB-C2, it still continues to be widely used, and most likely this situation will not change for a long time.

— DVB-S (satellite). The first...generation of the digital DVB standard for satellite broadcasting. Nowadays, it is relatively rare due to the advent of a more advanced DVB-S2, which is also backwards compatible with the original DVB-S.

— DVB-S2 (satellite). The most advanced and popular of today's digital satellite broadcasting standards. Being the heir to DVB-S, has retained compatibility with it; therefore, manufacturers often limit themselves to installing only a DVB-S2 tuner on their TVs — it allows you to receive both major satellite broadcast formats.

Internet services supported by the TV. This list may include multimedia platforms (YouTube, Vimeo, Netflix, etc.), social networks (Facebook, Twitter), online TV broadcasting systems, as well as more specific resources, sometimes very far from the original purpose of TV (for example, a game centre for online saves and interaction with other players).

Support for a particular service usually means that the TV has a special application to access it (or several services at once). Many of these resources can also be accessed through a browser (see "Features"), but special support often provides additional convenience and extended capabilities.

The TV's connectivity is based not only on wireless technologies (described above), but also on a wired connection. In particular, video transmission can be carried out through VGA, Component, Composite, SCART connectors. Some of them also provide sound transmission, in addition to which there may be a mini-Jack (3.5 mm). and other ports for interconnection with external devices. More about them:

— USB. Connector for connecting external peripheral devices. The presence of USB means at least that the TV is capable of playing content from flash drives and other external USB media. In addition, there may be other ways to use this input: recording TV programs to external media, connecting a WEB camera (see same paragraph), keyboard and mouse to use the built-in browser and other software, etc. The specific set of options depends on the functionality of the TV, it should be specified separately in each case.

— Card reader. A device for working with memory cards, most often in SD format. The main use of the card reader is to play content from such cards on a TV; such an opportunity is especially convenient for viewing materials from photo and video cameras — it is in such devices that memory cards are w...idely used. There may be other ways to use this function — for example, recording from the broadcast or even exchanging files between the card and the TV's storage. It is worth bearing in mind that SD cards have several subtypes — original SD, SD HC and SD XC, and not all of them may be supported by the card reader.

— LAN. Standard connector for wired connection to computer networks (both local and the Internet). Mostly found in models with Smart TV support (including Android TV devices; see related paragraphs). A wired connection is less convenient than Wi-Fi, not as aesthetically pleasing, so manufacturers place more emphasis on a wireless connection, as a result of which the speed indicators of the LAN connector are not indicated, and in some cases may be unacceptable for 4K broadcasts.

— VGA. Analogue video input, also known as D-sub 15 pin. Initially, the VGA interface was developed for computers, but due to the emergence of more advanced standards like HDMI (see below) and technical limitations (the maximum resolution is only 1280x1024, the inability to transmit sound), it is considered obsolete and is used less and less. So it makes sense to specifically look for a TV with such a connector mainly in cases where it is planned to be used as a monitor for an outdated computer or laptop.

— Component. Video interface with 3 connectors, each of which is responsible for its part of the video signal. This separation provides high bandwidth and noise reduction, making the component input the most advanced analogue video interface available today. So, it is capable of working with HD, and in terms of image quality it significantly surpasses S-Video and composite connector, closely approaching HDMI (see below).

— Composite. Combined analogue audio/video interface, it is this connector that is usually called the A/V input. Actually, there are usually three connectors in the composite interface — separately for video and the left/right channel of stereo sound (on TVs with one speaker that do not support stereo, one of the audio connectors is missing). The image quality when working through such an input is not high, and HD formats are not supported at all; on the other hand, the composite interface is extremely widespread not only in modern, but also in outdated equipment like VHS video recorders.

— SCART. The large universal multimedia connector, the largest connector used in today's consumer-grade video equipment. Works mainly with an analogue signal, which is why it is considered obsolete; however, still not falling into disuse. One of the reasons for this "longevity" is versatility: SCART does not have its "own" signal format, this standard only describes the connector. In fact, having the appropriate cables, you can connect different types of incoming signals to such an input — composite, S-Video, etc. Moreover, it is technically possible for such a connector to work as an output (for the same signal types). However the specifications of SCART connectors in different TVs may be different, so a specific list of compatible interfaces needs to be specified separately.

— COM port (RS-232). A connector originally developed for computer technology. It is used as a control on TVs: by connecting the device to a computer, you can control TV parameters and various settings, sometimes quite specific and inaccessible when using a conventional remote control.

— Mini-Jack (3.5 mm). A connector most commonly used as an analogue audio (line) input. One of the options for using such a connector is to connect audio for a video signal transmitted via VGA, S-Video (see above) or another interface that does not support audio transmission. However, with the appropriate cable, any audio source can be connected to the 3.5 mm mini-Jack port, including a mobile device like a smartphone or a pocket player. In this case, the sound can be played both through the speakers of the TV, and on external speakers connected to it. Another option for using this input is to connect a microphone for chatting via Skype.
