The accessory further contains a mission critical processor (104) for handling mission critical functions of transmit and receive audio as well as PTT and emergency. In response to a failure of the mission critical processor (104), the mission critical functions are maintained by handing over the mission critical functions to the non-controlling device in a manner transparent to the user. The handover is triggered in response to status changes of the mission critical processor or as a result of battery depletion.

The caching engine generates a user-side key using content identifying information in the content request, and forwards the content request to the content provider IHS over a network as a content partial information request. In response to receiving a content partial information response from the content provider IHS over a network, the caching engine generates a content-provider-side key using header information in the content partial information response. The caching engine performs a hashing operation on the content request using a combination of the user-side key and the content-provider-side key to produce a hashed content request, and uses the hashed content request to retrieve content from the cache.

  • Patent number: 9749665
    Abstract: Method for distributing multimedia licenses by a server to a plurality of user devices in a distribution system of a multimedia service, the access of which is protected by a first protection. This method comprising verifying that computing resources used by the server do not exceed a maximal threshold, if so, generating and then transmitting regular licenses including said first protection in response to user device requests, otherwise switching the server to a singular mode of distribution aiming to protect the access to the multimedia service using a second protection, independent of the first protection; to generate and to transmit to the devices one singular license comprising the second protection; to verify that the computing resources do not exceed the maximal threshold, if so, to switch from the singular mode to a regular mode so as to protect the access to the multimedia content using only said first protection.

  • Patent number: 9584556
    Abstract: A client device includes a media player and a client proxy. The client device is to provide a static playlist of segments for a multimedia program to the media player, wherein the static playlist is independent of changes in network performance, and to update a local variant playlist for the multimedia program responsive to changes in network performance. The client proxy further is to convert a first segment request from the media player for a first segment listed in the static playlist to a second segment request for a second segment listed in the local variant playlist, wherein the first segment and the second segment are different encodings of the same multimedia content. The client proxy further is to access the second segment from the media server using the second segment request, and provide the second segment to the media player as the first segment.

  • Patent number: 9503785
    Abstract: Systems and methods are disclosed for performing anti-piracy countermeasures in order to prevent unauthorized access of protected content. A conditional access system may be modified to include a counter. The counter is incremented every time the conditional access system receives a request that is a potential indication of pirate activity. The counter may also be decremented every time the conditional access system receives a request indicative of legitimate activity. If the conditional access system receives a management message containing a key required to access content keys, the conditional access system cheeks the counter. If the counter is below a threshold value, the conditional access system obtains the key. However, if the counter is above the threshold value, the conditional access system disregards the key contained in the management message, thereby losing access to protected content.

  • Patent number: 9462075
    Abstract: An encrypted cached content system includes a user IHS, a content provider IHS, and a caching IHS. The caching IHS includes a caching engine that is configured to receive a content request from the user IHS. The caching engine generates a user-side key using content identifying information in the content request, and forwards the content request to the content provider IHS over a network as a content partial information request. In response to receiving a content partial information response from the content provider IHS over a network, the caching engine generates a content-provider-side key using header information in the content partial information response. The caching engine performs a hashing operation on the content request using a combination of the user-side key and the content-provider-side key to produce a hashed content request, and uses the hashed content request to retrieve content from the cache.

  • Patent number: 9450748
    Abstract: Embodiments may include receiving a protected version of content that includes multiple encryption chains each including encrypted blocks of content. The protected version of content may include one or more initialization vectors for decrypting the encrypted blocks of content and discard information that specifies non-content portions of one or more data blocks to be discarded after decryption. Embodiments may also include performing chained decryption on the multiple encryption chains using the initialization vectors specified by the decryption information. The chained decryption may result in a sequence of decrypted data blocks. Embodiments may also include, based on the discard information, locating and removing the non-content portions of one or more data blocks in the sequence of decrypted data blocks. Embodiments may also include generating the protected version of content. Embodiments may also include performing any of the aforesaid techniques on one or more computers.

  • Patent number: 9401806
    Abstract: The present invention develops a wireless communication transmitting scheme which allows a desired receiver to stably receive data so that data are not tapped by a third party when a transmitter transmits data to the receiver in a wireless scheme. In particular, the third party not a desired receiver taps, a bit error probability of received data is maintained to have about 50%, so that the third party cannot substantially obtain valid data. A suggested scheme of the present invention may transmit security data in a state that a transmitter and a receiver do not have a secret key unlike an existing cryptography.

  • Patent number: 9350968
    Abstract: An enhanced digital video recording device is provided to enhance digital video recording performance, features and user experience. The recording device has a processor and a storage unit, where the storage unit has multiple computer memory units, such as SSDs, HDDs, and video transcoder for transcoding video data in a data stream. The video transcoder interacts with a controller of the storage module to differentiate between video data packets and non-video data packets of the data stream based on one or more determination criteria. Responsive to data stream being video data stream, the video transcoder transcodes the data packets of the data stream. Responsive to the data packets being encrypted, the video transcoder obtains and/or generates encryption keys and decrypts the data packets. The video transcoder also periodically provides feedback data generated from transcoding process to enhance the transcoding operations.
