  • Patent number: 9609280
    Abstract: A method for controlling access to a plurality of channels by a unit comprising a security module, each channel being encrypted by a specific control word and having a channel identifier, this method comprising the steps of: tuning to a first channel having first channel identifier and receiving first messages containing a first control word; decrypting the first messages and using the first control word; storing the first control word and the first channel identifier; tuning to a second channel having second channel identifier; calculating the second control word by: calculating a root control word with an inverse cryptographic function F?1 using the first control word and the first channel identifier; calculating the second control word with the cryptographic function F using the root control word and the second channel identifier; and using the second control word to access the second channel.

  • Patent number: 9432709
    Abstract: Example embodiments relate to a system to prevent manipulation of transmitted video data including an Integrated Receiver Decoder (IRD) receiving audio/video data and a display device. The IRD may include a device to transmit an HDMI compliant audio/video stream toward the display device. The system may further include a device to add an over-encryption layer to the HDMI/HDCP stream before reaching the display device and a device to remove the added encryption layer so as to recover the HDMI/HDCP stream, before processing the HDMI/HDCP stream by the display device.

  • Publication number: 20150128167
    Abstract: A method to enhance broadcast content of an event received by a television set by supplying additional information related to the event. A user builds a request message for getting more information through a displayed menu where some items are extracted from metadata broadcast with the content. The request message, completed with user preference and identification data, is sent to a management center. The latter performs a search in local databases or in remote databases of providers distributed in a cloud comprising a plurality of internet services and resources. The search results are filtered before sending to the television set in the form of enhanced data comprising abstracts including at least text, or any combination of text with graphics or pictures.

  • Patent number: 8837731
    Abstract: A system includes a remote control device and a security device, wherein both devices share a unique and constant common key, algorithms or protocol specific to a pair formed by the remote control device and the security device. The unique and constant common key, algorithms or protocol are set up during a device initialization phase. The remote control device is configured to communicate wirelessly with a receiver of the security device. The remote control device, which is paired with the security device sending data towards the receiver, includes an encryption module and a memory to store the unique and constant common key. The data is encrypted by the encryption module with the unique and constant common key, and the security device includes a decryption module and a key corresponding to the unique and constant common key to decrypt the data received from the remote control device.
