    Abstract: A mechanism for memory reduction in picture-in-picture video generation is disclosed. A method of embodiments of the invention includes receiving, from a transmitting device, a plurality of video streams at a receiving device coupled to the transmitting device, wherein a first video stream of the plurality of video streams is designated to be displayed as a main video and one or more other video streams of the plurality of video streams are designated to be displayed as one or more sub videos to the main video. The method further includes transforming the one or more other video streams into the one or more sub videos, temporarily holding the one or more sub videos in a compressed frame buffer, and merging, via pixel replacement, the main video and the one or more sub videos into a final video image capable of being displayed on a single screen utilizing a display device, wherein pixel replacement is performed such that the one or more sub videos occupy one or more sections of pixels of screen space pixels occupied by the main video.

    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.

    Abstract: A system communicating over a full duplex control channel of a multimedia communication link by using synchronization signals that may also function as a logical link command. Synchronization indicators are exchanged between two communicating devices for maintaining synchronization of a logical link. At least two different types of synchronization signals may be sent between the two devices as synchronization indicators. A first synchronization signal is used by default to maintain synchronization of a logical link. A second synchronization signal is used in place of the first synchronization signal to maintain synchronization of the logical link. The second synchronization signal may be used to imply a virtual link command to indicate that a device is ready to receive data or has successfully received data over the virtual link.

    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.
