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.

System encoder and decoder for verification of image sequence

A method and apparatus are provided for controlling data flow by storing variable length encoded information bits in a circular buffer in a write operation to a virtual write address comprising a first wrap bit value appended by a current write address within the buffer address range and generating an interrupt alarm if the virtual write address crosses a virtual alarm address comprising a second wrap bit value appended by an alarm address within the buffer address range, where the first and second wrap bit values each toggle between first and second values every time the current write address or alarm address, respectively, wraps around the circular buffer, thereby synchronizing data flow in the circular buffer and/or preventing buffer overflow.
