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 describe a multimedia stream switch capable of multiplexing the audio and the video data of a multimedia stream separately. The multiplexing features of embodiments of the invention enable a multimedia stream switch to control each multimedia data type separately instead of multiplexing the whole streams (i.e., multiplexing sets of audio/video data together). Furthermore, prior art multimedia stream switches need to regenerate audio clocks by using phase locked loop (PLL) circuitry which incurs manufacturing and development costs. Embodiments of the invention provide the mixing of audio and video data from different sources without the need for PLL circuitry.
摘要翻译：本发明的实施例描述了能够分别多路复用多媒体流的音频和视频数据的多媒体流交换机。本发明实施例的多路复用特征使得多媒体流切换能够分别控制每个多媒体数据类型，而不是将整个流复用（即，将多个音频/视频数据集合在一起）。此外，现有技术的多媒体流交换机需要通过使用产生制造和开发成本的锁相环（PLL）电路来再生音频时钟。本发明的实施例提供了来自不同来源的音频和视频数据的混合，而不需要PLL电路。

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.
