Abstract
The present application relates to a system for verifying integrity of a stream of image frames including an encoder logic module and a decoder logic module. On source side, a test line insertion logic module receiving the stream is arranged upstream to the encoder logic module encoding the stream. The test line insertion logic module is configured to include one or more test lines into the image frames. A color coding is assigned to the one or more test lines. The color coding is selected from a coding scheme. On destination side, a test line detection and extraction logic module is arranged downstream to the decoder logic module receiving the encoded stream. The test line detection and extraction logic module extracts the color coding from the received image frames and verifies extracted coding data against the coding scheme. The coding data comprises at least the extracted color coding.
