Buy conditional access module 12 channel. CAM modules for T2 and beyond

Modern TV models are equipped with built-in digital TV tuners that can independently decode closed television programs without using an external receiver. But in order for the built-in tuner to function, there is a mandatory requirement - the presence special module signal conditioning, that is, the CAM module.

By definition, a CAM module is electronic device, which is used as an adapter when decoding paid media content supplied to the encryption. It can support work with one coding system or several at once. In addition, such a device has a special slot designed for a smart card, an individual access key that each subscriber of digital satellite television providers receives.

In turn, the smart card has unique number and allows the service provider to control the degree of access to encrypted TV channels for each specific user.

How exactly does the conditional access module work?

In practice, everything looks more simple and clear than in theory. Each new satellite television subscriber receives a smart card containing access keys. It looks like a simple plastic card with a small electronic chip. The card is placed in the CAM module slot, after which it is inserted into the CI slot on your TV.

As you know, any TV channels that go on your satellite TV are divided into two groups, namely:

Free (open). These are the simplest and most common channels that are always open to all users;

Paid (closing). These include the most interesting, high-quality and informative TV channels. They can be dedicated to sports events, show the life of wild animals, or they can broadcast good domestic and foreign films, for example, in HD quality. Naturally, it makes no sense for the provider to provide them for free, so they are encoded.

The built-in digital tuner reads access codes from your smart card and decodes all closed channels according to the terms of your package, so you can always enjoy high-quality and interesting TV programs.

An important advantage of the built-in digital tuner and CAM module is that there is no need to use additional equipment, namely a separate external receiver in the form of a set-top box. This is very convenient, because everything you need is already on your TV. While a separate receiver takes up space, collects dust, and a whole bunch of wires are used to connect it. In turn, a TV with a conditional access module is much easier to mount on vertical surfaces, for example, on a wall. Minimum wires and maximum space savings.

Which TV models are suitable for using the CAM module?

It should be noted that not all models television devices can be used with the conditional access module. It is important that the TV has a built-in digital TV tuner and also supports the appropriate digital TV satellite standard (eg DVB-S or DVB-S2).

There may be a connector for a CAM module on the back of the TV, but the TV may not have a built-in DVB-S or DVB-S2 tuner, and in order to make sure that your TV can work with a CAM module for receiving satellite TV, there must be a special threaded connector for connection satellite dish. If there is a connector for the CAM module but there is no threaded connector as in the photo, then your TV does not have a tuner for receiving satellite channels and accordingly the CAM-module will not work for you!!!

In general, almost all modern TV models of popular world brands (LG, Samsung, Philips and many others) are equipped with built-in digital tuners, as well as a special CI connector designed for the CAM module. If you do not know if your TV meets the requirements described above, then you can determine this by studying the technical characteristics of the device or by consulting the seller.

How is the CAM module configured?

With the help of the conditional access module, you can tune in satellite channels digital television. To do this, you just need to first make sure that the device is installed correctly and your TV "sees" it, and also reads data from the smart card.

The name of the module is the English abbreviation CAM (Conditional Access Module). It is translated into Russian as a conditional access module. This technical device, designed to decode an encrypted television signal transmitted via an outdoor antenna (DVB-T), satellite (DVB-S) or cable (DVB-C). To watch encrypted TV shows, one TV is not enough. Necessary optional equipment. About him and will be discussed further.

Why you need a CAM module

Most video content providers encode their streams to protect them from unpaid viewing. The most widely used signal coding systems are Conax, Irdeto, Viaccess, DRE-Crypt, VideoGuard. To decode each of them, a CAM module is required. The label indicates the coding system available to it. A module for digital television, as well as a card for a TV for receiving digital broadcasts, are an integral part of high-quality digital television.

By itself, the module can already decode free channels, but for a full-fledged viewing of digital television, you also need a conditional access card to paid ones. Without such a card, he will not be able to decode the signals. Their principle joint work lies in the fact that a chip is embedded in the card, which is connected to the service provider through the module. Decoding occurs in stages. First, the CAM module sends to the card all the information transmitted along with the video signal, including the signal decoding scheme. The keys to the scheme are recorded in the memory of the card. Then, having received a decryption scheme with keys from the card, the CAM module decodes the signal. Through it, the provider manages the subscriber connection, sending signals to disconnect at the end of the paid period, and the key for this is the card. As a result, you need to purchase a Kam conditional access module and a provider card for a TV for digital television.

How to choose the right module

First of all, it is necessary to clarify the technical characteristics of the existing TV. The data sheet will indicate which digital broadcasting standard the TV supports. For example, like this:
DVB-T support - yes
DVB-T2 support - yes
DVB-C - MPEG4 support

Models with these characteristics necessarily have a CI slot or a more modern CI + designed for the CAM module. The owner of such a TV only needs to choose a provider, buy a set of a module and a conditional access card. A TV card for digital television is usually sold complete with the CAM module itself. Technical support specialists will tell you how to set up the equipment. Older terrestrial-only TVs will require the purchase of a receiver with a CI or CI+ connector.

CAM modules differ from each other in two ways:

• the ability to receive one or more channels simultaneously;
• the possibility of reprogramming them when switching to another coding system.

CAM modules capable of decoding a signal in any one coding system are called single-channel. Each provider chooses a suitable system for itself and encrypts information in it. For example, NTV+ uses Viaccess, and Tricolor TV uses DRE-Crypt. Knowing which encoding system the selected provider works with, it is easy to select the desired CAM module.
A CAM module configured to receive several channels simultaneously or to reprogram from one system to another is called universal. It allows the user to watch multiple channels and record one channel while watching another (subject to recording access). The acquisition of such a module will allow you to change the provider without extra costs if necessary.
The most well-known manufacturers of CAM modules Neoton (France), SMIT (China), Aston (France) provide customers with a wide choice of both models. Judging by user reviews, the modules of these companies are reliable in use.
So, the reader who has reached these lines has received basic knowledge about digital broadcasting and modern viewing equipment. This is enough to understand if a CAM module is needed in the house. But to consider yourself an advanced user, you will need to read specialized literature and study the topic in depth. Nevertheless general rule for both beginners and advanced users, when choosing, a careful study of not only specifications CAM module, but also the capabilities of the existing TV.

The development and widespread use of digital television required technical solutions from television receiver manufacturers that allow them to receive television programs broadcast both directly from satellites and cable or satellite TV providers. Many well-known companies coped with this problem quite easily by equipping television panels with built-in digital receivers (tuners). And the issue of additional viewing of paid video content from different providers was resolved using a special module for the TV. About types and possibilities this equipment, as well as the rules for its installation - in the material below.

What is a CAM module

As of the end of 2018, almost all modern TVs (LG, Samsung, etc.) allow you to receive television digital programs, for which it is enough to connect the cable coming from satellite dish(dishes). However, in this case it is possible watch digital channels only unscrambled- after all, tuners built into TVs do not have the keys necessary for paid video content. Also, television receiver manufacturers, as a rule, do not provide for the possibility of flashing built-in receivers and / or entering keys using a smart card, which excludes the possibility of watching pay TV channels coming from satellite and cable TV providers.

So that TV owners can view paid content, in television receivers, manufacturers provide the ability to connect an external CAM module, with which you can decode the received television signal and tune channels. In the general case, a CAM module for a TV (Conditional Access Module) is a small computer designed to decode a digital video signal and then match it with the model of the TV receiver on which the owner installed it.

Principle of operation

Works this device only with special smart card, which is purchased from the provider and installed in the CAM module. And the module directly connects to the TV through the Common Interface slot (CI slot) or connects to it using a special CI adapter (5V only), which is usually included in the delivery set of the TV receiver.

Important! After the CAM-module with the inserted smart card is installed and connected to the TV receiver, the subscriber is identified, and the program will independently read the video signal decryption keys and decode them into a format acceptable for the TV.

Only in this way does the user get the opportunity to receive digital television, both free and commercial channels.

Advantages

According to the owners modern TVs with built-in receivers Sony Bravia etc.), CAM-modules have a number of advantages, including:

• reception of coded TV channels;
• the ability to do without the purchase of an expensive external receiver;
• ease of installation of the CAM module and auto tuning TV receiver;
• control the module using the TV remote control.

Types of CAM modules

By technical features And functionality There are several types of CAM modules.

Installing the CAM module in the TV

Depending on the model television receiver There can be two options for installing the CAM module:

• via CI slot.
• using a special CI adapter.

Attention! Before buying a CAM module, you should make sure that your TV panel can receive unencrypted (free) digital channels. If such a translation is not provided, then the installation of the CAM module seems useless.

Algorithm

The installation sequence of the CAM module is the same in all cases and boils down to:

• disconnecting the TV receiver from the power supply network;
• installing a smart card into the module in such a way that the contact pads of the CHIP are facing the side where the colored label is pasted (in this case, the smart card must be inserted all the way);
• connecting the CAM module to a television receiver in accordance with its instruction manual;
• turn on the TV and check the reception of scrambled channels.

Precautionary measures

To ensure the safety and performance of the CAM module, you must adhere to some recommendations. Thus, rough mechanical impacts should be avoided, as a result of which damage to the body of the device and the components inside it is possible. And the installation and connection of the modules must be carried out in strict accordance with the instructions attached to the television receiver. In addition, you should:

• do not overheat the module;
• do not bend the smart card and do not store it near sources of strong electromagnetic radiation;
• do not remove the smart card from the module without special need;
• do not remove the CAM module from the TV receiver unless absolutely necessary.

ISP protection and the possibility of hacking

Due to the fact that there is quite tough competition among providers offering paid television content, they are forced to somehow label their products. They do this using various ways signal encoding, which allows you to provide your client with the opportunity to receive the content ordered and paid for by him.

However, the main coding formats have long been known and standardized, thanks to which users lacking decency can easily crack access codes to broadcast TV channels. To protect against hacking, providers are forced to constantly change code combinations, which naturally complicates hacking. Satellite codes are also changed, which are then transferred to service providers for flashing client smart cards.

Providers most often use the encryption technique, which is based on key redundancy algorithm. It consists of the following - a package television programs is formed from the corresponding lists of codes. In addition, each channel receives a unique combination, which includes the provider's key and a set of user codes that have paid for the service. Based on this cipher, consisting of a specific digital set, the client is able to accept the software package ordered by him.

However, after a certain period of time, the provider changes his code, and then the whole set of client keys should stop working. By changing the combination, the service provider prescribes to smart cards new key only to those customers who paid for the package of commercial channels on time. For other users, reception of programs is terminated.

Interesting! At present, the BetaCrypt 2 code system, which uses a complicated method of searching and assigning keys, has become widespread. For the previously used Conax and BetaCrypt coding systems, the algorithm for creating digital combinations is completely deciphered.

So, thanks to the CAM-module for television receivers, many paid TV channels from various providers become available to users. As you can see, the installation of such equipment is not particularly difficult, but for its long and successful operation during operation, precautions should be taken.

Modern TVs provide their users with great opportunities, including watching TV channels in high resolution with excellent sound, but this requires additional equipment as a module for a TV and a subscriber's personal smart card. It is also worth considering that not all models provide a CI slot, therefore, in order to be able to connect digital television with great choice TV channels require the purchase and installation of a TV receiver, in which a smart card with a module will be installed.

Many TV models from leading manufacturers such as Samsung, LG, Sony have long had a number of built-in designs that provide TV screens with advanced features. Developers are trying to equip their TVs with convenient devices, thereby freeing the user from having to connect additional equipment that takes up space. For example, built-in tuner or in another way digital receiver allows you to receive streaming video and decorate the signal of different broadcast formats. However, in order for it to cope with its tasks, it definitely needs external signal support - this is provided by the CAM module.

This device resembles a small computer that first conducts digital stream decoding, and then sends a signal to match it with specific model TV. This electronic device, equipped with a special card, is designed to play digital signal and pay channels with high definition. And, if the TV model has a built-in DVB-C tuner, the device in question will save users from additional wires, installing a separate set-top box and a second remote control.

How does he work

In order for a technical device to independently read the information it receives (meaning, for example, paid media content), the service provider's client needs to purchase a Smart card. This is a plastic card with a microchip that identifies the subscriber and provides him with access to digital TV and paid channels. It is inserted into the CAM module. After the adapter with the card inside is installed in the TV. The user only needs to configure the list of received TV channels.

The configured equipment makes it possible to receive media content with various expansion and quality options, while the image will be automatically adjusted to certain parameters. Latest Models considered electronic devices can independently record streaming video, and play it at the time necessary for the subscriber.

What are CAM modules

According to technical specifications, the entire range of manufactured conditional access devices for coded channels is divided into types. Most simple modules- T2 and single-channel with support for only one coding system. Multi-channel and universal models are also offered.

1. Single channel module is able to decode pay channels broadcast only by the selected provider (satellite). If you change the service provider or satellite with a different broadcast system, the module becomes inoperative.
2. Multichannel Models devices allow you to switch from one coding system to another using SIM cards from different providers. The device automatically recognizes the inserted SIM card, rebuilds and updates the software.
3. Universal module manufacturers are flashing to work with several signal encoding systems. The device can automatically correct signal parameters, configure programs, work with SIM cards of any provider. Suitable for working with paid software packages.

If speak about module cost, then in specialized stores you can see a fairly large range of prices. As a rule, the cost of the first option ranges from 1500 - 3000 rubles. The price of more modern models varies in the region of 5000-6000 rubles. Experts recommend not to opt for too cheap options. Otherwise, this will lead to an imminent replacement, as they will not cope with the latest technologies, and the purchase will be much more expensive than planned.

The advantages of such equipment

Before buying a new LG, Philips or Sony TV, it is worth considering purchasing a model with a built-in receiver and a slot for a CAM module, since such electronic equipment has undeniable advantages.

1. More profitable for the price. Purchasing a conditional access module will cost less than a regular TV set-top box or Smart set-top box.
2. Easy to install and set up. Simply insert it into the slot along with the subscriber's card and swipe simple setup equipment.
3. Doesn't take up space. This device is slightly larger than a plastic card, which is inserted into the CI slot on the TV panel. It does not require additional shelves, especially if the TV panel is mounted on the wall, as for an external set-top box. Besides, such wireless equipment does not take up an extra outlet, because it is powered by TV.
4. Simple control from the TV remote control.

How to install a CAM module in a TV

Connection and configuration does not require special knowledge. The main thing is to make sure that for the TV it is suitable device- the panel has CI-slot. The installation algorithm is identical for any TV, be it Lg or Samsung.

1. First you need to correctly install the smart card into the adapter. i.e. insert a card electronic chip up, while holding the module facing you (the provider's logo is placed on it).
2. The adapter, complete with the card, is inserted into the PCMCIA slot of the turned off TV, facing outward.
3. Now you can turn on the TV. A corresponding inscription about connecting new equipment should appear on the screen.
4. Often you do not have to configure anything, just run automatic search programs.

If nothing happens after you turn on the TV, the hardware is most likely installed incorrectly. You should turn off the TV and do all the installation steps again. Health Status can be checked in the TV menu, depending on the manufacturer, the name of the corresponding item in the interface may be called “CA Module”, “CA Interface”, “CAM”, “CI Interface”, “Common Interface”.

If the equipment is connected, the TV sees it, but the channels are not tuned, you should contact your service provider.

Precautions for use

When operating the CAM module, the user is required to comply with the following recommendations:

• avoid serious mechanical impacts: falls, squeezing;
• when installing the module in the TV receiver, strictly follow the manufacturer's instructions;
• make sure that the module does not overheat;
• do not store the SIM card near sources of electromagnetic radiation;
• if you need to remove the SIM card from the module, strictly follow the instructions;
• in order to avoid damage to the connector, do not unnecessarily remove the module from the TV.

Protection of providers from software hacking

Paid content is offered by a large number of providers. Each service provider protects their channel packages with one or another coding system. To make it more difficult for attackers to break into program codes, providers systematically change the control key in the code combination. The receivers of subscribers who have paid for the service receive a code combination via satellite to decrypt coded channels.

The CAM module is designed for owners of LCD or plasma TV models that are equipped with a built-in receiver and support HD Ready or Full HD digital formats. Such an electronic device, equipped with a smart card, provides the opportunity to watch paid TV channels. Easy Installation does not take much time and does not require special knowledge. The main thing is to make sure that the TV has a built-in DVB-C tuner and a CI slot for such an adapter before purchasing.
