CI + slot - Common Interface Plus - also known as digital TV decoder slot is usually located on the back of digital TV ( also known as integrated TV DVB-T2 ) in which you can insert cards service to watch free and paid TV channels (such as HBO, Star Movie, Disney Channel) with just antenna or cable, not a dedicated decoder.
The advantage of a TV with a CI + slot is that you can simply watch premium TV channels (usually foreign channels or some specific high-quality channels), no need to spend money to buy and install one more. the decoder next to the TV, avoids wasting space and inconveniences when connecting with complicated wires and must use 2 remote: a TV remote and a decoder remote.
Currently, digital TVs equipped with CI + slots are still relatively few. Samsung TV is the first TV model on the market to add a digital decoder slot in model H5510 , H5562 . Recently, TCL has just officially launched the B2600D , 2800D and 2820D television series with additional digital decoder support.
In addition, when deploying digital TV line equipped with CI + slot, Samsung combined with An Vien Television with an encrypted CAM card for users to watch free TV channels in addition to typical premium channels. An Vien is like an Oriental channel or a super-sharp channel.
A CAM card is a long form card like an ATM card that is often likened to a "phone sim" for television, this card decodes the radio station's toll-free TV channels and transmits it to the viewer to enjoy.
The CAM card is like a phone sim for TV - allowing you to watch premium channels.
The usage of the CAM card is similar to that of a phone sim card, if you want to use it, it is imperative that you have to top up and register for the services. Depending on the service package you subscribe to, the number of channels as well as the monthly amount you pay will vary. Up to the present time (October 2014), only An Vien Television channel is supporting CAM cards to watch digital channels provided.
