Abstract
A video receiver receives a security level of a video source. The security level is stored in a blanking region of a video transmission. The video receiver compares the security level of the video transmission with a security level stored in the video receiver. The video transmission is processed as a function of the comparison of the security level of the video transmission with the security level of the video receiver.
Claims15
A process in a multi-level security device comprising:
- receiving a security level of a video source at a video receiver, the security level stored in a blanking region of a video transmission;
- comparing the security level of the video transmission with a security level stored in the video receiver;
- and
- processing the video transmission as a function of the comparison of the security level of the video transmission with the security level stored in the video receiver;
- wherein the security level comprises one or more of a horizontal synchronization (HSYNC) pulse and a vertical synchronization (VSYNC) pulse, and wherein the one or more of the HSYNC pulse and the VSYNC pulse comprise security information for port authentication;
- and
- wherein the security information represents a port type of one or more of the video source and the video receiver.
4 more elements
A non-transitory machine-readable medium comprising instructions that when executed by a processor execute a process comprising:
- receiving a security level of a video source at a video receiver, the security level stored in a blanking region of a video transmission;
- comparing the security level of the video transmission with a security level stored in the video receiver;
- and
- processing the video transmission as a function of the comparison of the security level of the video transmission with the security level stored in the video receiver;
- wherein the security level comprises one or more of a horizontal synchronization (HSYNC) pulse and a vertical synchronization (VSYNC) pulse, and wherein the one or more of the HSYNC pulse and the VSYNC pulse comprise security information for port authentication;
- and
- wherein the security information represents a port type of one or more of the video source and the video receiver.
4 more elements
A system comprising:
- a computer processor;
- and
- a memory coupled to the computer processor;
- wherein the computer processor and the memory are operable for:
- receiving a security level of a video source at a video receiver, the security level stored in a blanking region of a video transmission;
- comparing the security level of the video transmission with a security level stored in the video receiver;
- and
- processing the video transmission as a function of the comparison of the security level of the video transmission with the security level stored in the video receiver;
- wherein the security level comprises one or more of a horizontal synchronization (HSYNC) pulse and a vertical synchronization (VSYNC) pulse, and wherein the one or more of the HSYNC pulse and the VSYNC pulse comprise security information for port authentication;
- and
- wherein the security information represents a port type of one or more of the video source and the video receiver.
