Mostly receivers are supplied with two types of outputs: digital, analog. The receiver serves as a repeater for the high-frequency signal in case the antenna cable is single. Briefly consider what constitutes the equipment, tell you how to connect the receiver to the TV.
Assigning a receiver
The receiver is used to decipher a digital, sometimes coded signal, to watch programs on the TV.It has long been observed: when using high technologies, we transfer more programs with one frequency band. Ether, cable, without a difference. There are 10 programs on one frequency channel, among which sometimes there is a radio. According to the transmission medium, the digital broadcasting standards are divided into groups:
. The receiver and the
- S remote are satellite.
- T - ground.
- C - cable.
Letters are visible adorning the boxes of receivers sold by stores. First of all, choose the right one. Ask what the difference is made up. Protocols. Different frequencies, modulation types, bit rate, and other parameters. Can I create a hybrid receiver that receives all types of broadcasts? Rarity. Antenna ground broadcast, satellite different. Therefore, there are two cables. Another thing is the splitter is used, the possibility of the receiver operating in the repeater mode is provided.
Requirements for frequency, bit rate, modulation type imposes transmission medium. Air, cable, vacuum. Today, each group of standards has survived the second edition, backward compatibility is preserved. DVB-T2 is suitable for receiving the first generation broadcast. We take into account the moment. Connecting the receiver to the TV, make sure: the plasma panel is devoid of built-in modules. Concerns terrestrial broadcasting. According to the type of connection, the methods of using the difference between the C, S, T groups are round zero. In the first case, the signal comes from the ground, in the second it is caught by the plate, in the third it is received by the antenna decorating the roof.
Ports of receiver
Antenna input of the TV in transit through the receiver
As a result, we get a 75 Ohm cable connector, connect it to the receiver. If a splitter( splitter) is used on the roof, we will transmit the signal to the TV set in transit. The rear panel RF OUT is used. The connector is a 75-ohm cable, with F-connectors at both ends. Take time to hope that the receiver has amplified the signal, not a fact. A 75 Ohm cable is taken as short as possible. The plate is by definition active, at the antenna( even the collective one) the signal level is lame, avoid introducing additional attenuation.
The receiver will receive digital channels of DVB standards, the TV catches analogue broadcasting. Assuming: the built-in card reception panel is devoid. And if two signal sources? For example:
- Multiplex DVB-T2 standard for terrestrial digital communications.
- Satellite dish on DVB-S protocol.
Both receivers are connected in series. Each for a dedicated protocol. If necessary, connect the antenna input of the TV to the RF OUT output of the latter. When you want to watch local channels on the analog connection. The requirements are similar: the length of the wire is as short as possible. Receivers avoid putting on each other. If you look closely, slits are cut at the bottom. Contributes to the flow of air naturally. There is cooling equipment. Accordingly, the paths are not blocked.
TV interaction with
signals Transmission of a decoded signal to an
TV Two common formats are released for connecting a receiver-TV: analog, digital.
- Analog goes according to the 3RCA connector scheme. Called tulips, bells. The wire looks like a bunch, three cylindrical plugs are hanging on both sides. The pins are surrounded by steel beaters, for which the connector type has been named. On suitable receivers signed pinout signal. The rim is provided with an individual color. Yellow will serve as video transmission, white mono or left stereo speakers. Red goes to the right speaker, if you want to listen to the sound around.
- The HDMI interface is used to transmit complex signals with maximum quality. Please note that several generations have been released, we choose the cable accordingly. Option on the TV is not lower than provided by the receiver. The device can be seen signed. Optionally worth marking 3.0.Indicates the third generation of the standard. On the HDMI interface simultaneously transmitted sound, image. Resolution not lower than FullHD.It is determined by the electronic filling of the receiver. The HDMI standard is designed to work with much higher resolutions( and the second generation).The catch is in finding the standard description. About HDMI, while omnipresent Wikipedia is silent.
VGA-3RCA wire
Old TVs are not always equipped with a 3RCA connector. If the West interface is generally accepted since the end of the Second World War, the Russians are deprived of pleasure. On electron-beam TVs, there is usually a SCART connector. A kind of defense, invented by France, against the invasion of Japanese technology. Although the barricades did not last long, while fellow minds shouted "But pasaran," the advisers managed to adopt the connector. Any Knight adjustment times equipped with SCART.
There is a plus, bulky connector contains structurally diverse types of analog interfaces in the composition. It is easy to find a SCART pinout( the VashTechnik portal has repeatedly quoted).With every old TV went a piece of wire, topped with a plug. Moreover, collapsible or build the desired structure. Including 3RCA connection.
It's easier to buy a ready-made solution in the store. Note, the connector is designed to work on the input, not on the output. Otherwise, you will have to look again. Connect the receiver to the TV will help special hybrid connectors. Equipped with a switch that changes the direction of flow. The device should work on the input. As for the new digital TVs, none goes without a 3RCA connector. HDMI usually has even a few. To attach there a disc player or home theater.
Receiver may be connected to the TV indirectly. Will serve the central unit home theater. The second option - the receiver for the TV.But for the reception of digital broadcasting. Just the name matches by luck, an oversight. You can find out about receivers on the Yandex Market in the Electronics- & gt; Audio and Video Technology- & gt; Audio Equipment section. Is a sound analogue of home theaters, which are more designed to work with the image.
However, audio receivers are quite suitable for work. There are advanced sound modes. Different formats are supported. It remains to add, most receivers( for receiving digital broadcasting, audio) are equipped with media playback facilities. More often USB port. Reads flash drives, hard drives. It is more convenient to attach the media to the receiver, bypassing the TV.To transfer the signal is better to use the HDMI interface. The corresponding cable is deprived of a typical kit. Before you connect the receiver to a TV, you will need to purchase the product.
Almost completely described the capabilities of digital television reception receivers. Audio will describe other reviews. We assume that other receivers can be equipped with a digital optical audio output interface, usually the step is not practiced by manufacturers. By the way, if there is a desire to listen to the accompaniment in 5.1 mode, usually home theaters provide an opportunity. Inside there are special algorithms for transforming two channels into six. Discussed the topic in the reviews.
As for the image, the television also deals with it( for example, in 3D).Created special programs for personal computers, building the desired graphics. The broadcast signal is rationally transmitted to the video card, sent from it to the television. How to do it? We'll have to expand the desktop to the desired space. Really simple? That digital technologies are useful, any operations will make with the image and a sound.
