DVB-S stands for Digital Video Broadcasting - Satellite and it is the standard for broadcasting a TV signal via satellite. This system transmits digital audio and video signals in the MPEG format. DVB-S2 is an enhancement of DVB-S which improves the efficiency and reliability of the broadcast channels.
Your TV has an integrated DVB-S2 tuner that is backward compatible with DVB-S, which enables you to view free satellite channels from the service provider. In order to view the encrypted/scrambled channels you need either a Conditional Access Module (CAM or CI-Module) with a smart card or a Set top box depending on the implementation by the service provider.
