System and method for securely transmitting video data
Abstract:
Exemplary embodiments provide a system and method for securely transmitting video data to an electronic display. The video data may be transmitted using a wired or wireless application. Raw video data is encoded as a plurality of JPEG frames. A plurality of primary packets are created which may contain one frame or a portion of a frame of video. Each primary packet contains a unique header with information about the packet and a unique security key. A redundant packet and header are created for each primary packet and header. After transmission each packet and header may be analyzed to determine if it was transmitted properly. If the primary packet was not transmitted properly or was an unintended transmission, the system may discard the primary packet and proceed with the redundant packet. If the redundant packet was not transmitted properly or was an unintended transmission, the entire frame may be discarded and the previously accepted frame may be repeated within the video decoder. If multiple frames are discarded, the system may display a default image. The packets are re-assembled and displayed if they are the intended transmission.A system and method for securely transmitting video data to an electronic display. The video data may be transmitted using a wired or wireless application. Raw video data may be encoded as a plurality of frames. A plurality of packets may be created which may contain one frame or a portion of a frame. Each packet may contain a unique header with information about the packet and a unique security key. After transmission various properties of each packet may be analyzed to determine if they are acceptable. The packets may be re-assembled and displayed if they are the intended transmission. A previous frame, default image, or default video may be displayed if any of the packets are not acceptable. Alternatively, a pair of packets may be transmitted together so that if a primary packet is rejected, the system could analyze a redundant packet to complete the frame and provide a minimal interruption of video signal.
