Abstract: A system, method and apparatus for implementing a wireless point-to-point interface that securely and robustly delivers digital content from a generalized content source to a generalized content sink. The system, method and apparatus performs in a manner that is sufficiently secure and robust to serve as a replacement for the delivery of HDMI content over cable. The system, method and apparatus is also applicable to the delivery of other types of content traditionally delivered over cable, including but not limited to Digital Video Interface (DVI) content, composite video (CVSB) content, S-video content, RGB video content, YUV video content, and/or various types of audio content.

Abstract: An audio/video switching system is described that selectively enables multiple heterogeneous audio/video sources to transmit data to a single audio/video sink such as a display or audio/video repeater. The audio/video switching system supports format conversion to enable, for example, multiple different audio/video formats to be transmitted to the audio/video sink using a single link. In some implementations, the single link is a high-bandwidth, high-quality wireless link for carrying high definition and standard definition audio/video signals. Various home theater systems that include such an audio/video switching system are also described herein.

Abstract: The present invention is directed to a system, method, and apparatus to transmit/receive TMDS signals using general purpose differential transmitter and receivers. In an embodiment, the general purpose differential transmitter and receivers are designed to operate with differential signaling schemes such as LVDS and LVPECL. In one aspect, embodiments according to the present invention enable the re-configuration of existing and fully-characterized LVDS/LVPECL transmitter/receiver cells to support TMDS (using minimal sets of external components). This provides considerable cost and development time savings, thereby allowing the development of products much more expediently. In another aspect, embodiments according to the present invention provide interfacing methods and systems between differential signaling schemes such as LVDS/LVPECL and TMDS.

Abstract: A system, method, and apparatus that improves the efficiency of HD content delivery systems. An embodiment of the invention eliminates unnecessary encoding overhead due to TMDS encoding in HD content delivery systems. An embodiment of the invention further allows for increased error protection at lower overhead in HD content delivery systems. Furthermore, embodiments of the present invention provide less expensive and more efficient techniques for transmitting content protection information in HD content delivery systems. The invention is applicable to HD content delivery systems such as DVI and HDMI systems, including systems that employ novel data transmission techniques of the present invention as well as conventional content delivery systems. The invention is applicable to copper and fiber HD content delivery systems.

Abstract: A improved method and system for regenerating a video pixel and/or audio sampling clock in a system that wirelessly transfers video and audio content from a content source to a content sink.

Abstract: The present invention is directed to a system, method and apparatus for implementing a content delivery system that includes at least one bi-directional distribution system between a generalized content source and a generalized content sink. The bi-directional distribution system enables the content source and the content sink to coordinate with each other to determine the capabilities of the content distribution system, the content source, and the content sink, and to best control the content format accordingly.
