  • Patent number: 10630934
    Abstract: Systems and methods for selectively enabling enhanced high dynamic range (HDR) metadata for enhanced HDR playback of media content stored on a media disc are provided. Media discs may be authored with a base layer media content in accordance with a non-enhanced HDR media profile. Media discs may also include enhanced HDR metadata. In order to enable the use of the enhanced HDR metadata, a media player in which the media disc is inserted for playback may first seek authorization from a third-party resource, such as an authorization server. Only after obtaining authorization is the media player allowed to playback the media content stored on the media disc in conjunction with the enhanced HDR metadata. If authorization is not obtained, the media player may only play the base layer media content.

  • Patent number: 10608851
    Abstract: A continuous-time sampler has series-connected delay lines with intermediate output taps between the delay lines. Signal from an output tap can be buffered by an optional voltage buffer for performance. A corresponding controlled switch is provided with each output tap to connect the output tap to an output of the continuous-time sampler. The delay lines store a continuous-time input signal waveform within the propagation delays. Controlling the switches corresponding to the output taps with pulses that match the propagation delays can yield a same input signal value at the output. The continuous-time sampler effectively “holds” or provides the input signal value at the output for further processing without requiring switched-capacitor circuits that sample the input signal value onto some capacitor. In some cases, the continuous-time sampler can be a recursively-connected delay line. The continuous-time sampler can be used as the front end sampler in a variety of analog-to-digital converters.

    Abstract: Systems, methods, and computer-readable media for facilitating call continuity when transferring calls between mobile access networks to voice over internet protocol networks. The method includes recognizing availability of a voice over internet protocol network during a voice call established via a wireless access network. Thereafter, a data connection between a user device and the voice over internet protocol network is established. A transfer of the voice call from the wireless access network to the voice over internet protocol network is initiated by initiating a three-way call. Such a three-way call includes a first portion routed to a destination device via a public switch telephone network and a second portion routed to the user device via the voice over internet protocol network.

  • Patent number: 9154827
    Abstract: Delivery of conditional access data to a receiver that is able to connect to a plurality of scrambled programs. Conditional access for a current channel is handled using standard ECMs delivered with the channel. In parallel, the receiver retrieves an ECM for a separate stream comprising control words for every channel. The control word of this ECM is used to descramble the separate stream to access the control words for every channel. In a preferred embodiment, these control words are super-encrypted using channel keys and the receiver is only able to obtain channel keys for channels for which it has access rights. In case the control words are super-encrypted, they are decrypted. Upon channel change, the relevant retrieved control word is used to descramble the new channel. Also provided is a receiver device and a transmitter device. According to a variant, the control words received in the separate stream is treated only upon a change of channel.

  • Patent number: 9124929
    Abstract: A method for communication, including distributing over a communication network multiple channels of digital content, which are encrypted using different, channel-specific control words, and transmitting over the communication network, different, channel-specific entitlement control messages from which the control words are derivable such that each of the different channel-specific control words is derivable from any of the different channel-specific entitlement control messages by authorized receivers of the channels on the communication network. Related methods and apparatus are also included.

  • Patent number: 9083998
    Abstract: A system and method that receives a tune request in a switched digital video (SDV) system, where the tune request includes an identifier of a set-top box, and an SDV channel. The method receives a content stream associated with the SDV channel. The method retrieves conditional access (CA) information from a local cache, where the CA information includes encryption information for the content stream. The method converts the content stream to an encrypted content stream using the encryption information, and sends the encrypted content stream to the set-top box.

  • Patent number: 9059854
    Abstract: A protocol provides authentication of peripheral devices by a computing device to which the peripheral device connects. Computing devices include a verifier with a public key that authenticates multiple associated private keys. Private keys are embedded on peripheral devices. When the verifier is able to authenticate a connected peripheral, particular functionality is enabled that may not be enabled for peripherals that do not authenticate.

    Abstract: A method includes receiving, by a client device associated with a particular user, product details for video content including a purchase option identifier (ID) for the video content from a video service provider. The method includes requesting, by the client device based on a single sign on (SSO) protected call, a playback uniform resource locator (URL) for the video content from an orchestration layer associated with the video service provider. The method also includes receiving the playback URL, an entitlement ID associated with the particular user for the video content, and the encrypted content. The method includes obtaining a digital rights management (DRM) license for the encrypted content based on the entitlement ID, and decrypting and playing the video content based on DRM rules associated with the video content.

  • Patent number: 9043827
    Abstract: A method and system of providing conditional access to encrypted content includes receiving unsolicited multiply encrypted video content and first decryption data over a broadcast network. Partially decrypted video content is obtained by decrypting a first layer of encryption of the encrypted video content using the first decryption data. The partially decrypted video content is stored. A request for viewing the encrypted video content is transmitted and second decryption data is received. A second layer of encryption of the encrypted video content is decrypted using the second decryption data.

  • Publication number: 20150135210
    Abstract: A method includes receiving a request for media content at a residential gateway from a device coupled to the residential gateway and sending a media content request to a server based on the request. The method includes receiving a video data stream of the media content at the residential gateway. Data packets of the video data stream enable generation of the media content at a first resolution. A first subset of the data packets include tags that enable identification of particular data packets usable to generate the media content at a second resolution that is lower than the first resolution. The method also includes determining a display characteristic of a display device coupled to the device and sending the particular data packets to the device when the display characteristic indicates that the device is to receive the media content at the second resolution.
