    Abstract: Embodiments relate to half-duplex bidirectional transmission of data compliant with a first standard (e.g., Universal Serial Bus (USB) standard) over a physical channel of a multimedia link for transmitting audio/video (“A/V”) data compliant with a second standard (e.g., Mobile High-Definition Link (MHL) standard) between a source device and a sink device using time division multiplexing (TDM). The source device sends units of data including A/V data and forward data compliant with the first standard at first times whereas the sink device sends units of data including backward data compliant with the first standard at second times between transmissions from the source device. The first times do not overlap with the second times. Synchronization signals may be added to the first and second units of data to align character symbols embedded in the first and second units of data.

    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 mechanism for facilitating dynamic timestamp-less clock generation for transmitting media streams over shared channels is described. In one embodiment, a method includes periodically counting and producing, at a first media device, a number of audio/video (“A/V”) samples, generating a pace clock based on the number of A/V samples, generating a target clock based on the pace clock, and transmitting an A/V media stream based on a frequency difference between a pace frequency relating to the pace clock and a target frequency relating to the target clock.
