A system for determining the authenticity of a received channel via an Internet port of a smart TV having (a) a first streamer for receiving a channel A via said Internet port, and forwarding a respective video stream of the channel to a synchronizer; (b) a second streamer for receiving a same channel A via a traditional port, and forwarding a respective video stream of the channel to said synchronizer; (c) said synchronizer synchronizing between the two streams, and outputting the two synchronized streams respectively to a correlator; and (d) said correlator correlating between corresponding frames of the stream, and when a similarity above a predefined threshold is determined, declaring channel A as received via the Internet port as authentic; otherwise, if a similarity below a predefined threshold is determined, declaring by the correlator that channel A as received via the Internet port is non-authentic. |
