Abstract: Cryptographic access control of multimedia video is presented. A method includes generating as metadata an access control policy (ACP) associated with video, the ACP including authorization rules and cryptographic information associated with an encryption policy; encrypting the video according to the encryption policy; and encoding the encrypted video with the authorization rules and the cryptographic information, which may be used to decrypt and render the encoded video. As an example, an authorized receiver device having credentials and/or capabilities matched to the authorization rules may extract the ACP information from the encrypted video and use it to decrypt and properly render the video. The method may further include visually encoding the encrypted video with at least portions of the authorization rules and the cryptographic information, such that the visually encoded video is renderable as the video by an authorized device, but is renderable as visually unintelligible video by an unauthorized device.

Abstract: A technique for streaming digital video content to multiple clients involves establishing a logical group of IP-connected stream servers, generating state information at multiple stream servers within the logical group, sharing the state information amongst stream servers in the logical group, and using the shared state information to respond to resource failures within the logical group. By sharing state information within the logical group of stream servers, stream servers with the shared state information can quickly take over the active streams from a failed stream server within the logical group. The quick transition of responsibility from one stream server to another enables the streaming network to provide continuous streaming of digital video content to the viewer without interruption.

Abstract: The current invention relates to a computer-generated method for optimizing placement of advertising content across multiple different devices. The system can allocate advertising campaigns and plans to various inventory types based on the probability of accurate consumer matching. Consumer matching can be achieved by generation of look-alike models in a consumer's device graph to predict future consumption behavior. The system includes an interface through which an advertiser can access relevant information about inventory and success of a given placement.

Abstract: A controller for controlling the output of an audio-video feed has an input for receiving audio-video content and a vector engine arranged to produce a continuous metadata value of M dimensions at intervals from the audio-video content. The metadata value may indicate aspect of the video content such as rate, pace, tone or other such information. A low pass filter and hysteresis filter are then provided to filter the continuous metadata value to produce a binary output. The binary output is provided to a retrieval module arranged to control the audio-video content in dependence upon the binary output. In this way, automated segmentation of audio-video content may be reliably achieved.

Abstract: A content processing integrated circuit includes a system-on-a-chip (SoC) that further includes a processor to receive an authentication request from an external device for authenticating if the SoC is permitted to receive encrypted content from the external device, and to receive the encrypted content once the SoC is authenticated. An authentication processor is provided and coupled to the processor to authenticate the SoC to the external device when the processor receives the authentication request, and to generate a decryption key for decrypting the encrypted content. A decryption processor is provided and coupled to the processor and the authentication processor to receive the decryption key from the authentication processor and to decrypt the encrypted content with the decryption key. A wireless display system with such SoC is also described. A method of implementing a secure and robust content protection in a SoC is also described.
