How a TV tuner works
A digital terrestrial receiver is a device for modulating an analog signal into a “digital” one. The tuner is useful to all TV owners who prefer to watch TV channels in a modern standard. Its picture and sound quality is higher than that of analog television. The principle of operation is elementary: the antenna receives a signal from a repeater or television center, transmits it to a tuner, where it is recoded and sent in finished form to a monitor or TV.
To enjoy the benefits of digital TV channels, you only need to set up the device once. All subsequent times the set parameters will be applied automatically.
Healthy! In fact, purchasing a TV tuner is a budget-friendly way to improve the picture quality on your TV without the urgent need to replace it.
How to choose a TV tuner?
To choose the best DVB T2 TV tuner, you need to consider the basic characteristics of the devices. Understanding technical parameters is a must-have skill when purchasing any electronics. The main thing is to pay attention to the following characteristics.
Kinds
Today, analogue television is rapidly dying out; it is being abandoned globally in favor of digital. All because of the low picture quality and vulnerability to interference from the old standard. Modern TV tuners can work to encode broadcasts from previously analog, satellite and cable TV channels. Each type requires a special receiver capable of working with a specific broadcast format.
The most popular tuners are DVB-T, DVB-T2, as they provide signal modulation from public television. Broadcasts via satellites are mainly carried out by mobile operators or channels with subscription access. For their operation, you will need DVB-S, DVB-S2 format devices. To watch cable TV digitally, you need a DVB-C tuner.
Most devices can support 1-2 types of broadcasting. However, the best TV tuners for TV can decode almost all signals. Their price is a little higher.
TV tuners are also divided by installation type:
- Internal . They are installed in a TV, which creates an additional load and has limited functionality.
- External . They include additional functions and take over the entire decoding process without affecting the resources of the monitor or TV.
Manufacturers
TV tuners are most similar to DVD players in their design, codecs and decryption algorithms. Due to the similarity of the devices, companies previously focused on producing DVD players quickly switched to producing receivers. The most popular brands are BBK, HARPER, D-COLOR. Younger companies from China have also performed well: Oriel, Selenga, World Vision.
Connection method
Built-in devices for connecting to a personal computer use a direct route - installation into a connector on the motherboard. External devices predominantly use triple wire and can be equipped with cinch connectors. Due to the obsolescence of the port, most companies are switching to a USB connection. The best connection standard now is HDMI. Advanced devices support several or all connection methods at once.
Control method
The remote control is mainly used to control the TV tuner. In terms of convenience and functionality, the approach is significantly superior to conventional buttons, especially buttons on the body of the device. The remote control resembles a regular television model, but with the help of programs it can be configured to control a computer. If there is an HDMI connection port, you can control the picture on the TV from a personal computer.
Criteria for choosing a set-top box for digital TV: what is important and what is not
The selection of a digital set-top box for TV is carried out according to certain criteria related to parameters and technical characteristics. First of all, you need to pay attention to the following:
- The number of encoding formats supported by the set-top box. It is desirable that their number be maximum. A prerequisite is support for MPEG-4 signal encoding.
- Screen resolution. Modern receivers support HD standards and higher. They will not work with older SDTV models. If the set-top box matches an outdated device, then the image quality will remain at the same level. The device will only broadcast digital channels. This must be taken into account when choosing game consoles for your TV.
- TV connector. They may differ in different devices. In early models it could be RCA - “tulip” or SCART. Modern models are usually equipped with HDMI ports. If the connectors of the set-top box do not match the television connectors, you need to use a special adapter. Please note that a direct connection via HDMI improves image quality.
- Number of supported media formats. In order to view photos, audio and video files on a digital TV, the set-top box must support the following standards: video – MKV, AVI, AVC/H.264, DivX, MPEG4, audio – MP3, WMA, AAC, AC3, photo – JPEG, JPG, RAW. This data is indicated in the receiver parameters.
- Card slot. It makes it possible to view not only the standard set of 20-30 programs, but also additional channels through a paid card provided by the provider.
- Additional functions. Among them are Internet access, Timeshift, connecting external devices, etc. In this case, there must be a sufficient number of USB ports.
Digital set-top boxes are presented in the widest range of products on the electronics market. All of them are conventionally divided into different categories according to their capabilities and functionality. The cost of each device depends on this, determined by the following indicators:
- Country of origin and rating of digital TV set-top boxes.
- Availability of ports and connectors, their number and variety.
- Possibility of connecting to the Internet.
- Control method.
- The ability to record TV shows for later viewing at a more convenient time.
In accordance with the technical characteristics, all consoles can be classified:
- Budget. The capabilities of these devices are significantly limited. They are used only for their intended purpose - to watch TV shows. A good inexpensive option for a summer residence.
- Economy class. They are only slightly superior to budget models due to the increase in broadcast channels. This expansion is achieved through a slot for a paid card. External drives can be connected to which the necessary information is recorded.
- Middle price segment. These set-top boxes are in high demand and are actively used by most users. They are distinguished by high broadcast quality and advanced functionality. The cost is relatively low and quite affordable for consumers.
- Products for premium TV. Equipped with a powerful operating system that speeds up the functionality. An Internet browser is installed that provides access to all network content. The capabilities of such set-top boxes are superior to other models in all respects.
