Cardsharing, also known as control word sharing technology, is a widely used method of sharing channel subscription. Cardsharing allows multiple users to simultaneously access the pay television networks using a single authorized subscription card. The device with the card is the satellite Cardsharing server or host and the other users who can also access the card through an internet or local network are the Cardsharing clients.

The primary reason for users not being able to access to the paid TV channels is because they are encrypted (locked) by the service providers. The standard satellite receivers are not designed to decrypt (unlock) such paid channels or support Cardsharing. The Linux based satellite receivers such as Dreambox not only have the capacity to decrypt the paid channel but also are designed to support Cardsharing.

This technology works with the help of Linux based satellite receivers which can provide digital satellite viewing through an internet connection. Some of the popular satellite receivers are Dreambox, Azbox, Technomate etc. These receivers have an Ethernet connection which connect multiple users and also have the ability to use special software to send and receive codes. The satellite receiver needs sharing protocol software, which helps in decoding the encrypted service providing conditional access. Some of the widely used software are Mgcamd, CCcam, Newcs, Newcamd, CCcam being the most popular one.

For the Cardsharing to work properly it is important for the network devices of the multiple users to have proper configuration. The multiple devices must have a common IP address for ascertaining the exact location of the devices and for proper communication between them. Thus, the Cardsharing server or host can know the exact location of the Cardsharing clients by its direct IP number.

The first step is to insert the authorized subscription card in the Cardsharing host or server which is connected to the internet. The next step is to download and install the CCcam software and run it in the host to configure it establish connection with the Cardsharing clients or receivers. The main function of the host is to transfer the decrypted channel codes to the Cardsharing receivers. Every 2-5 seconds the paid channel picture is encrypted by the satellite service provider which requires being decrypted. The CCcam software directs the communication between the provider and the Cardsharing host for decryption of codes. The Cardsharing receivers simultaneously communicate with the host for password which is delivered by the host to the receiver. The whole process of decrypting and sharing happens in fraction of seconds making the viewing pleasure uninterrupted.

Cardsharing technology is the most convenient way of saving money for subscription of paid TV channels. It divides the cost of subscription among the multiple users who are basically paying for sharing the subscription. However, the wrong side to this technology is that it has become widely used way of plagiarize decryption of paid channels which is not in favor of the service providers. The illegal users attach multiple legitimate cards to their server and charge a small subscription fee from the receivers. Hence, making Cardsharing an illegal affair.



Television industry has witnessed wide range of innovations over the past years. Satellite TV being one such innovation that revolutionized the television watching experience for the viewers by introducing a variety of channels with high picture quality to them. Though satellite TV opened up vast options for entertainment, the service providers still had some limitation in broadcasting some foreign pay channels. This limitation for the viewers can be due to national restrictions as some countries restrict the broadcast of foreign channels in their country.  The limitation can also be due to package restrictions as some channel companies buy the rights of programs and charge a fee from the subscribers for broadcasting the same. The answer for TV lovers to the overcome this restriction is Cardsharing.

Cardsharing is a technique through which multiple independent users can have simultaneous access to the pay channels with a single authorized subscription card. A cardsharing server like Dreamboxwith CCcam software installed can enable the decryption of the blocked channels and sharing of the same to the other cardsharing clients. However, to receive any channel it is essential that the satellite service provider has access to those channels. Thus, cardsharing bring together the subscribers with similar interests and subscribes them as one identity using cccam server. The cardsharing clients can, thus, receive more channels at cheaper rates by dividing the subscription cost.

The size of the satellite service provider’s dish is an import factor to be considered while cardsharing. The size of dish determines the number of channels that can be received. The installation for cardsharing devices is not very difficult and the directors for installation are easily accessible on web. The software for the receiver can be downloaded with the remote control itself. Cardsharing has therefore become extremely popular across the world due to is cost effectiveness and easy installation processes.

Through cardsharing facility, people are able to view channels broadcasted anywhere in the world. This has not only benefited the subscribers but also has boosted the channel business which is recording growth in viewership for their cannel shows. Sports channels are reaping the optimum benefits through this facility.

Social business is other best impacted business sector through cardsharing. For hotels and social places entertainment is one of the key factors boosting their growth in business. With cardsharing facility, they can offer wider entertainment options for their customers and the cost effectiveness of the facility also decreases their investment cost for extra entertainment.

The illegal use of cardsharing resulting in ban of its usage in some countries creates a negative for this innovative technology. But the popularity of cardsharing continues to drive the business growth of the cardsharing device companies like Dreambox.
