One or more circuits for use in a transceiver that is collocated with a satellite dish, may receive a satellite signal carrying media content, and remove content protection from the received media content. After removing the first content protection, the one or more circuits may apply second content protection to the media content. The content protection applied by the one or more circuits may adhere to a different protocol, utilize different keys, and/or otherwise be distinguishable from the content protection that was removed. After applying the content protection, the one or more circuits may transmit the media content onto one or more links between the satellite dish and one or more client devices. The removal of the content protection may comprise descrambling and/or decrypting the media content. The application of the content protection may comprise scrambling and/or encrypting the media content.

A receiver device having a processor, memories, descrambler and decoders modules configured to produce a sequence of elementary media content packets. The receiver device further comprises a marker unit configured to mark data in the sequence of elementary media content packets according to a pattern defined by an internal parameter associated to the receiving device. The marker unit is configured to determine, in the sequence of elementary media content packets at least one segment of a predetermined length and starting at a predetermined position in the sequence, to divide the segment into a predetermined number of contiguous windows including data of all or part of at least one elementary media content packet. Each window in the segment defined in the sequence of elementary media content packets is indexed by an index defining a position of a window in the segment. The marker unit codes the internal parameter by applying a mathematical transformation function, obtaining a resulting bits string, calculates position indices of a predetermined number of windows on the basis of all or a portion of the resulting bits string, said predetermined number of windows being lower than the number of windows in the segment, and modifies data in the windows designated by the calculated position indices. The windows including modified data and the windows including original data from within the segment of elementary media content packets a unique pattern representing the internal parameter associated to the receiving device.

The present disclosure discloses a video encryption method comprising: acquiring image frames continuously by using an image acquisition component, and storing the image frames into a frame buffer; acquiring a time encryption sequence, and using the time encryption sequence to obtain an address encryption sequence; and reading each of the image frames in the frame buffer according to the address encryption sequence to obtain an encrypted video when the frame buffer is full. The method continuously acquires the image frames and uses the time encryption sequence to obtain the address encryption sequence, and when the frame buffer is full, each of the image frames in the frame buffer is read according to the address encryption sequence to obtain an encrypted video. In addition, the present disclosure also provides a video encryption apparatus, an image capture device, and a computer readable storage medium, which also have the above-mentioned beneficial effects.

An embodiment of a system for securing media content includes a digital media device comprising a memory associated with a secure element. The memory contains a private key and storage for at least one group key. The private key is used to decrypt transmissions from a remote access control system that are encrypted by a corresponding public key. The digital media device further comprises logic configured to respond to a first message received from the remote access control system encrypted by the public key and including a first group key, the logic responding to the first message by decrypting the first group key and storing the first group key in the memory of the secure element. The digital media device further comprises logic configured to decrypt a content key with the first group key. The content key is used to encrypt media content stored on a medium accessible by the digital media device.

A system and a method for processing an image. The method includes the steps of: receiving a source image having at least one sensitive portions arranged to present intelligible sensitive information; and processing, with a predetermined redacting method, the at least one sensitive portions of the source image to generate an output image including the intelligible sensitive information being transformed into an unintelligible form; wherein the sensitive information in the unintelligible form is adapted to be restored to an intelligible form.

A video signal transmitter or receiver for handling multiple video signals, including mainboard signal processing circuitry, one master fiber module, and one or more add-on fiber modules. Video data signal for the multiple videos are transmitted over the master and add-on fiber modules, but no video control signal is transmitted over any add-on fiber module. Video control signal for all of the multiple videos are transmitted on a first subset of channels of the master fiber module in a multiplexed manner. The mainboard signal processing circuitry cooperates with the signal processing chip of the master fiber module to process all video control signals, with the master fiber module processing video control signals for at least two videos. Non-video signals are processed by the mainboard circuitry and transmitted on a second subset of channels of the master fiber module (same as or different from the first subset of channels).

A set-top box (STB), digital video recorder (DVR), video player or other host device receives and interacts with a transcode module to provide enhanced transcoding capabilities that may be useful in placeshifting or other applications. The transcode module includes a host interface that couples to and communicates with the host device. The transcode module also includes a processor that receives an encrypted media stream from the host device via the bus interface, decrypts the encrypted media stream, transcodes the encrypted media stream to a different format, re-encrypts the transcoded stream, and provides the re-encrypted media stream to the host device via the host interface. The transcoded media content may be placeshifted to a remote player, stored at the host, or used for any other purpose.

A method and system for delivering encoded content are provided. A holdback representing a portion of the encoded content is extracted, thereby damaging the encoded content. The damaged encoded content is distributed. The holdback is transmitted to enable reintegration of the holdback with the damaged encoded content to restore the encoded content.

Methods and systems for providing content. A selection of a single virtual channel may be received from the user. Virtual programming data for the single virtual channel may be accessed. The virtual programming data may define content to be provided over the single virtual channel. The content may be provided over the single virtual channel in accordance with the virtual programming data.
