Abstract: A transmitter and receiver for communication of multimedia streams across a multi-lane communications link. The transmitter packetizes multimedia streams according to a link layer protocol and distributes the packets across multiple lanes of a communications link. The entire packet, including the header and payload, can be distributed across the lanes in an ordered sequence to increase utilization of the communication lanes. The transmitter may also packetize multiple multimedia streams and intermix the packets across the lanes of the communication lane. The receiver extracts the packets that are distributed across the multiple lanes and decodes the packets into the multimedia streams.

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 source device receives digital data comprising uncompressed video data and its associated metadata and compresses the video data. The source device generates an error code for each data word representing the compressed video data and its associated metadata. The data word and its corresponding error code are combined to form a code word. The source device organizes code words of the video data and its metadata into orthogonal data blocks and transmits the data blocks to a sink device. The sink device decodes corrupted data bits in the received data based on analysis of the error codes of the code words in the data blocks. Organizing code words into orthogonal data blocks helps isolate corrupted data bits in data blocks and enables the sink device to detect and correct corrupted data bits resulting from a single transmission error and to detect corrupted data bits resulting from multiple transmission errors.

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.
