Abstract: A device for communications over a multimedia communication interface. The device can be a source device including a scrambling circuit that receives control data associated with multimedia data to be transmitted over the multimedia channel of the multimedia communication interface, and generates scrambled control codes based on the control data. An encoding circuit generates transition minimized control codes based on the scrambled control codes. The device transmits the transition minimized control codes to a sink device via the multimedia channel. The sink device may also decode and de-scramble the transition minimized control codes received from the source device via the multimedia channel.

Abstract: Systems and methods for block noise detection and filtering are disclosed. One embodiment includes, computing difference magnitudes in pixel values for adjacent pixels in the image. The difference magnitudes can include horizontal difference magnitudes for horizontally adjacent pixels and vertical difference magnitudes for vertically adjacent pixels. One embodiment further includes using normalized sums of the difference magnitudes to determine a set of noise characteristics of the block noise and a set of image characteristics of the image and configuring inputs to the block noise filter using the set of noise and image characteristics.

Abstract: The present disclosure is related to a hardware component for communications over a multimedia communication interface. In one embodiment, a hardware component includes a disparity circuit that stores a disparity value. The disparity value indicates the disparity between the number of “1”s and the number of “0”s previously transmitted by the hardware component. The hardware component also includes circuitry for receiving multimedia data to be scrambled, encoded and transmitted by the hardware component. In one embodiment, the multimedia data includes video data and data island data. In one embodiment, the hardware component generates transition minimized intermediate codes based on values in the guard band data included within the video data and data island data. The hardware component generates encoded guard band codes that are transition minimized as well as direct current balanced. The hardware component transmits the encoded guard band codes over a differential pair of the multimedia communication device.
