A method and apparatus for controlling a group of the client devices to switch at least one client device of the group of client devices from a first conditional access system to a second conditional access system or to update conditional access parameters such as keys or watermarking parameters is disclosed.

An evidentiary management process for digital data associated with a localized Miranda-type process includes first detecting an electronic Miranda-type process trigger event, capturing audio/video of a suspect and storing a unique identifier of the suspect, selecting a particular stored Miranda-type warning variation, and then playing back the selected warning variation and storing an indication thereof. Then the unique identifier of the suspect and the stored indication of the warning variation are aggregated into a single data structure. An electronic anti-tamper process is then applied to the single data structure to generate an anti-tamper indicator, and the single data structure and anti-tamper indicator are stored or transmitted to a remote device.

A method implemented by a smartphone including a digital imaging device having an image viewing structure may include receiving designation of a user-selected embeddable content image filter, displaying the user-selected embeddable content image filter on the image viewing structure in combination with visual image content captured in real-time by the digital imaging device within a field of view at a current location, the user-selected embeddable content image filter maintained at a static position within an area of the image viewing structure independent of the visual image content captured in real-time by the digital imaging device, and merging the user-selected embeddable content image filter displayed as a foreground mask with the visual image content captured in real-time by the digital imaging device as background.

A method and apparatus for secure transfer of previously broadcasted content enables the secure transfer of previously broadcasted content between DVRs on a computer network.

A method and apparatus for secure transfer and playback of multimedia content enables the secure transfer of multimedia content from a digital video recorder (DVR) to a personal computer (PC) and further to a handheld device. A DVR determines which devices on a Local Area Network (LAN) are authorized to share and/or retrieve content from the DVR. The DVR receives a connection request from a PC on the LAN, authorizes the connection request and establishes a secure connection between the DVR and the PC. Once the secure connection is established, the DVR receives a request for multimedia content from the PC, prepares the multimedia content for transfer and transfers the multimedia content to the PC.

In one embodiment, a command is received from a video provider at a media rendering device, the command being a command to embed a subscriber ID in at least one video frame in a video stream. A random key, k is also received from the video provider at the media rendering device. An injective transformation is invoked for k and the subscriber ID, the injective transformation generating a sequence of pairs of: near-transparent patterns and corresponding time periods. Logical blocks of the at least one video frame in the video stream are overlaid with one of the near-transparent patterns for its one of the corresponding time periods. Related apparatus, systems, and methods are also described.

A wireless communication device comprises position determining system, a digital imaging system and a photograph customization system coupled to the position locating system and the digital imaging system. The position determining system is configured to provide information indicating a current position of the wireless communication device. The digital imaging system is configured to create digitally rendered images of visual content acquired thereby. The visual content is displayed on an image viewing structure of the digital imaging device while being acquired. The photograph customization system is configured to use the current location of the digital imaging device for providing one or more embeddable content ages and to display information from at least one of the one or more embeddable content images on an image viewing structure of the digital imaging device while the visual content being acquired by the digital imaging system is being displayed on the image viewing structure.

Methods and systems are provided for integrity verification of an audio-visual data stream. The method includes inserting a watermark into a frame of the visual data stream or into an audio window of a corresponding audio data stream, where the watermark includes: a hash code of the previous frame of the visual data stream and a hash code of the audio window of the audio data stream, and where the audio window corresponds in time to the previous frame of the visual data stream.
