    摘要: Embodiments of the invention are generally directed to conversion and processing of deep color video in a single clock domain. An embodiment of a method includes receiving one or more video data streams, the one or more video data streams including a first video data stream, the first video data stream being clocked at a frequency of a link clock signal. The method further includes converting the first video data stream into a converted video data stream having a modified data format, wherein the modified data format includes transfer of a single pixel of data in one cycle of the link clock signal and the insertion of null data to fill empty cycles of the converted video data stream, and generation of a valid data signal to distinguish between valid video data and the null data in the converted video data stream. The method further includes processing the converted video data stream according to the frequency of the link clock signal to generate a processed data stream from the converted video data stream, wherein processing includes using the valid data signal to identify valid video data.

    摘要: A method, apparatus and system for employing a secure content protection system is disclosed. In one embodiment, a certificate having a unique device identification associated with a first device is received, and, at a second device, a revocation list having unauthorized device identifications is received. The unique device identification is incrementally compared with the unauthorized device identifications of the revocation list, and media content is transmitted from the second device to the first device, if the unique device identification is not matched with the unauthorized device identifications of the revocation list.

    摘要: Embodiments of the invention are generally directed to transmission and detection of multi-channel signals in reduced channel format. An embodiment of a method for transmitting data includes determining whether a first type or a second type of content data is to be transmitted, where the first type of content data is to be transmitted at a first multiple of a base frequency and the second type of data is to be transmitted at a second multiple of the base frequency. The method further includes selecting one or more channels from a plurality of channels based on the type of content data, clocking a frequency on the first or second multiple of the base frequency according to the type of content data in the selected channels, modifying the content data to fit within a single output channel, and transmitting the modified data via a single output channel at the chosen multiple of the base frequency.

    摘要: 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.
