  • Publication number: 20110149032
    Abstract: Embodiments of the invention are generally directed to transmission and handling of three-dimensional video content. An embodiment of a method includes receiving a multimedia data stream including video data utilizing an interface protocol and determining that the received video data includes three-dimensional (3D) video data, where each frame of the video data includes a first vertical synchronization (Vsync) signal prior to an active data region, the active data region including a first data region and a second data region. The method further includes converting the 3D video data from a 3D data format to a two-dimensional (2D) video format, where converting the 3D video data includes identifying a region between the first data region and the second data region, inserting a second Vsync signal between the first data region and the second data region, and providing an identifier to distinguish between the first data region and the second data region.

  • Publication number: 20100177892
    Abstract: A method, apparatus and system for providing pre-authentication and keep-authentication of content protected ports system employing a ratio of one decipher processing engine (e.g., HDCP engine) associated with multiple ports is disclosed is disclosed. In one embodiment, a receiving device is pre-authenticated by a transmitting device, wherein the receiving device to receive a data stream from the transmitting device via a first data path. Further, a first High-Definition Content Protection (HDCP) engine is associated with a first port in the first data path, the first HDCP engine coupled with a second HDCP engine. The second HDCP engine is associated with a plurality of ports in a second data path, each of the plurality of ports associated with a memory pipe having state information relating to each of the plurality of ports, the state information being used to pre-authenticate the receiving device.

  • Publication number: 20100146265
    Abstract: 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.
