Abstract: In one aspect, a video processing device includes a processor and a transmitter, for example implemented as separate integrated circuits on a printed circuit board. Pins on the processor are coupled to pins on the transmitter via a data channel, for example conductive leads on the printed circuit board. Video data is transmitted from the processor to the transmitter via this data channel, which is high speed enough to accommodate video data. The transmitter also includes an encryption engine used to encrypt the video data. Encryption control data, which determines the encryption to be applied, is transmitted from the processor to the transmitter over the same data channel as the video data. This is more secure than transmitting the encryption control data over a slower separate data channel, because the high speed video channel is harder to tamper with.

Abstract: A mechanism for facilitating dynamic counter synchronization and packetization for data streams being communicated over communication devices is described. In one embodiment, a method includes detecting an audio/video (A/V) data stream being encrypted and/or decrypted using one or more high-bandwidth digital content protection (HDCP) engines, where the A/V data stream is communicated between a source device and a sink device. The method may further include dividing a video stream portion of the A/V data stream into a plurality of frames if the A/V data stream relates to a high-definition multimedia interface (HDMI), and synchronizing counter values with indicators within the plurality of frames.

Abstract: A system for receiving and decrypting media content encrypted according to the HDCP protocol is described herein. A receiving device coupled to a plurality of content channels includes an authentication engine to authenticate each content channel and to generate an initial session key associated with each authenticated content channel. The content channels can be, for example, an HDMI channel or an MHL3 channel. A session key indicator indicating a session key used to encrypt media content is received, and an updated session key is generated. The receiving device also includes a stream cipher engine configured to decrypt received encrypted media content using the updated session key. Decrypted media content can then be displayed, for instance on a display of the receiving device.

Abstract: Embodiments relate to routing encrypted data from a source to a sink via a router without decrypting the data in the router. The source authenticates with the router, the result of which produces a session key and a pseudo-random number. The router authenticates with the sink using the same session key and pseudo-random number. The router passes encrypted data received from the source to the sink without decryption and re-encryption.

Abstract: A system for detecting and mitigating bit errors in transmitted media is described herein. A source device encodes a frame of video, and generates an error code representative of a portion of the encoded frame of video. The portion of encoded frame and the error code are provided to a sink device via a communication channel, such as an HDMI or MHL3 channel. A second error code is generated by the sink device based on the portion of encoded frame, and the error code and second error code are compared to determine if the portion of encoded frame includes an error. If no error is detected, the portion of encoded frame is decoded and outputted. If an error is detected, the portion is replaced with frame data based on at least one other portion of encoded frame to produce a mitigated frame, and the mitigated frame is outputted.
