Pinout digital tuner dvb t2 tv samsung. DVB T2 digital tuner. What it is

When it comes to buying a new TV, most people turn their attention only to the quality of the transmitted image, as well as the technical characteristics on which it depends. The price of the device is also important. But the presence or absence of a digital tuner, as well as its type and quantity, interests very few people. Not many people pay attention to it. As a result, when there is a desire to connect and watch DTV for free, problems arise and you have to spend money to buy a DVB-T2 tuner separately.

Today we will look at what a digital tuner is, how it can be and how it works. This will allow you to approach the choice of a new TV more carefully and decide for yourself whether you need such a device built into the TV or not. Moreover, as already mentioned, the digital tuner can always be purchased separately.

What is DTV T2

Before considering the features and types of tuners that exist on TVs today, it is necessary to understand what this device is in principle and what it is for. Digital tuner   - This is a receiver or, as it is also called, a decoder that allows the TV to directly receive signals of various types of broadcasting and decrypt them.

Many new TV models already have built-in digital receiver   T2. In addition, there are sections in which there are two tuners at once - T2 and S2. Find out exactly what type of device is built into your TV, you can see its technical characteristics. If you have a built-in decoder that receives a signal of a different format, then the necessary tuner can always be purchased separately.

External tuners today are very popular, because not many Russian citizens have the opportunity to spend a large amount of money on the purchase of a new TV, and such a prefix allows you to expand the capabilities of an existing device. The most popular prefixes are the T2 format, which allow you to connect and watch digital terrestrial TV channels, as well as the DVB-S2 prefix. They buy it if they decide to install a satellite TV antenna, but there is no such decoder on the TV.

Broadcast standards

As already mentioned, a tuner built into a TV can receive one or several signals of different broadcasting formats. Consider the most common options.

• DVB-T. This receiver can take digital signal   television, which transmits a picture of a higher level of quality and clarity. To connect it, you need a regular TV antenna.
• DVB-T2. This is the second generation of DVB-T decoders, which differs from its predecessor by increased channel capacity, higher signal characteristics and its architecture. In Russia, this DTV signal format is mainly used. It is impossible to receive it through a DVB-T decoder, since these formats are incompatible.
• DVB-C. A very popular format capable of decoding digital signals. cable tv. To start using it, you need to insert the provider card into the appropriate slot.
• DVB-S. With it, you can directly connect satellite dish   to your tv.
• DVB-S2. Like T2, S2 is second generation dVB-S receivers. S and S2 are also incompatible, so an appropriate decoder is needed to receive a signal of this type. This format differs in increased channel bandwidth and the use of new modulation types.

When buying a TV, you should pay particular attention to labeling. So, you can see the inscription DVB-T2 / S2. This means that TV can receive both terrestrial and satellite digital channels.

DVB-S2 and DVB-T2 Features

Built-in digital tuner satellite tv   possesses certain features. In order to watch the available TV channels for free, it will not be enough for you to simply connect a satellite dish to a TV directly. You will also need to additionally purchase the CAM module.

The fact is that without it, you will not be able to view the encoded channels, but only those that are fully open. This is due to the fact that the companies engaged in the production of such TVs do not particularly think about this. In addition, it will be impossible to change the firmware or enter the code. External same satellite tuners, sold by us, possess a firmware in which all necessary codes are already entered.

That is why you will need to additionally purchase the CAM module, which you need to insert into the PCMCIA slot. After that, it will be necessary to launch a search for channels on the satellites specified by the provider and wait until the TV finds them. After that you will be able to watch all closed and paid channels that the CAM module will open for you. This is very convenient, since you do not need to buy and connect an additional receiver, and you only need one remote control to switch channels.

To connect the on-air digital channels, you do not need to buy anything extra. Simply connect the antenna to the TV and configure the DTV T2. Moreover, you can configure the channels either manually or by selecting “Autosearch” in the settings menu.

Buy a new TV?
  What to do to owners of old - analog or new TVs, but with the tuner of the "obsolete" standard? Fortunately, our Chinese friends have launched low-cost DVB-T2 tuners. Buy a new TV does not have to. Hurray, saved! Having learned that in my region the test broadcasting began in a new digital formatI ordered an inexpensive console to evaluate the prospects ...

Parcel
  The receiver was delivered by the China-Russian Post tandem in 16 days. It was packed in a “pimply” film and wrapped in adhesive tape.



  Under the film and tape there was a paper bag with hieroglyphs:



  But in a paper bag ... a box with a receiver (matryoshka, pancake):

  The English language describes the main features and characteristics of the device and the country of manufacture is China. As you can see, there are no hieroglyphs - the goods are clearly manufactured for export. There are no brands or logo of the manufacturer, a typical OEM product. As it turned out, this receiver was not exactly at Shenzhen Wisdigi Digital Products Co., Ltd., (then I found his twin brother under the brand name Digisat, but more on that later).

Receiver features:



   - Fully compatible with the format DVB-T2
   - Output HDMI 1.3   for high quality image
   - Component video output YPbPr
   - Digital coaxial   audio output
   - Digital LED display
   - Video output Scart
- Record   TV programs on external USB drives
   - Support function Timeshift
   - Function media playerbut
   - Support program schedule ( EPG)
   - Comfortable multilingual   menu
   - Support Teletext   and Subtitle

Contents of delivery
  Does not affect generosity.



  In the box was found:
   - DVB-T2 receiver
   - remote control
   - user manual (in English)
   - user's manual ()

Appearance and controls



  On the front panel of the device are:
  1. Power Button
  2. OK button
  3. MENU button
  4. Display
  5. Indicator standby
  6. Remote operation indicator
  7. Volume buttons
  8. Channel buttons
  9. USB 2.0
  This is enough to control the main functions of the receiver without the remote control and display modes of its operation.



  On the back of the device are switching connectors:
  1. Antenna input
  2. Antenna output
  3. Digital coaxial audio output
  4. HDMI output
  5. TV SCART output
  6. Component Y / Pb / Pr video output
7. Composite RCA video output
  8. Audio RCA output
  This set will allow you to connect the receiver to almost any television set, AV receiver and some computer monitors (on my, for example, there is an HDMI input). To connect the antenna, you need a coaxial cable with an F-connector.



  The remote control is supplied without batteries (2xAAA).

Preparing to turn on and start the device
  As you probably already understood, the set-top box can be connected to a TV or monitor using analog (component / composite) or HDMI output. In my case, a composite output was used to connect to a Panasonic TC-2150R TV. Sound can be output via HDMI, or you can use an analog stereo output. But the most unusual, in my opinion, is the presence of a third way to output sound — using coaxial output — a rarity for devices of this class. In my case, the stereo audio output was used - connected to the TV. For DVB-T2 reception, I used a collective outdoor antenna, one that is used to receive analog TV. After turning on the receiver shows the splash screen:



Initially, the screensaver was different, I changed the device with the firmware from the Russian clone and forgot to take a picture of the screensaver that was from the factory. You can see it in a respected eshikvtumane.



  At the first boot, the Installation Assistant appears, where you are invited to select the menu language, country, and start searching for channels. Busting the entire range takes 5-7 minutes. After the end of the search, a list of 10 TV channels and 3 radio stations appeared on the TV screen, it turned out to be a list of digital broadcast channels of the first multiplex.

Multiplex

Multiplex - transmission over one digital radio frequency channel of different television channels formed by different signal sources (studios and television companies). Also, the multiplex can include broadcasting channels, teletext signals, etc.

Timeshift
  This is what every fan dreamed at the moment when “the beer came to an end”, and the broadcast of the match is not interrupted by advertising. We put the program on pause and go about their business. After removal from a pause, the transfer will continue. In order for this to work, you need to connect a USB flash drive to the console, or an external hard disk with a USB 2.0 interface. Supported file systems are NTFS and FAT32. The settings indicate how much space on the disk / flash drive to allocate for the operation of this function from 0.5 to 4GB. You can connect multiple drives via USB hub.

Firmware update
  As I mentioned earlier, the receiver had a twin brother. in Russia under the brand name

This is the topic that came up when discussing a review of another similar tuner:

multiple PLPs have been enabled for DVB-T2 in July
  and all the tuners without the support thereof ceased to work.
  Local Orieli and Rolsona firmware have already been updated and everything works. With the support of the Chinese is usually more difficult

Pros:
  - DVB-T and DVB-T2 reception
   - Wide range of output connectors (HDMI, SCART, RCA)
- Cheaperthan local stores
   - On the "change" we get a multimedia player
   - All declared functions work
  Minuses:
  - There is no set of connecting cables and batteries in the remote.
   - It’s not a minus of the device itself, but the unclear fate of digital broadcasting in Russia. Coding introduction and use is possible. Of course, this will be a swine thing on the part of the authorities, for the third time to change “horses at the crossing” ...

Thank you all for your attention.

P.S. For more information, you can look reviews of such devices, because The software part is probably one (or very similar):
