    Abstract: Various arrangements for descrambling multiple television channels concurrently are presented. A set-top box may receive a first plurality of television channels as scrambled data packets. A previously-received locally-stored networking information table may be accessed that associates each of the multiple television channels with the same entitlement control message, as indicated by a packet identifier. An entitlement control message having the same packet identifier may be received. A smartcard may be used to decrypt the entitlement control message having the same packet identifier to obtain a first control word and a second control word. Scrambled data packets corresponding to the multiple television channels may be descrambled using the first control word and the second control word. These television channels may be stored and/or output for presentation by the set-top box.

    Abstract: A method and apparatus for streaming Over-the-Top (OTT) content on a network to subscribers is described. A digital video transport stream of an item of the OTT content is obtained via unicast streaming methods of a resolution and bit rate selected from an available set of different resolutions and bit rates for the digital video transport stream. The digital video transport stream of the selected resolution and bit rate is transmitted in the form of an IP multicast over the network to subscribers. Bandwidth utilization of the network is monitored so that switching of the bit rate to a different bit rate for the digital video transport stream can be controlled to provide adaptive rate control of the IP multicast.

    Abstract: The invention provides for a method and a device for the detection of a watermark in a signal. A first signal is compared with two or more second signals. The second signal with the closest match contains the same watermark as in the first signal. Data indicative for the second signal with the closest match is output as an indication of the watermark in the first signal. The invention further provides for a head-end system that provides watermarked content from which the watermarks are detectable by the watermark detection device.

    Abstract: A method and system for micro-cloud computing is described. An application serving node, which is a specifically configured piece of customer premises equipment such as a set-top box, is the server for a micro-cloud network. Various user devices that form part of the micro-cloud network, such as television sets and smart phones, communicate with the application serving node. The application serving node is configured with software that allows various heterogeneous types of data to be obtained and streamed to the user devices in multiple ways. The application serving node performs much of the processing necessary for such content streaming itself and thus represents an edge-based network architecture.

  • Publication number: 20130104162
    Abstract: A technique is provided for securely transferring programming content from a first device in a first layer, e.g., a trusted domain, to a second device in a second layer, e.g., outside the trusted domain. When a user requests that the first device transfer protected content to the second device, the first device needs to authenticate the second device. After the second device is authenticated, the first device may transfer to the second device the protected content, together with a rights file associated therewith. The rights file specifies the rights of the second device to use the protected content, according to its security level indicative of its security. These rights may concern, e.g., the number of times that the second device may subsequently transfer the protected content to other devices, the time period within which the second device may play the protected content, etc. The higher the security level of the second device is, the more rights accorded thereto.

    Abstract: A processing method of content intended for broadcasting is disclosed. The method includes, preceding broadcasting: encryption of the content by a plurality of control words, reservation of locations intended to receive a control message in the encrypted content, marking of each location with location information in the content, and storage of a key file comprising the control words. During broadcasting, the method includes: transmission of the encrypted content to a video server, transmission of the key file to a control message generator, broadcasting of the content encrypted by the video server, interception of the video server output by a replacement module, detection, by the replacement module, of location information of control messages in the stream of the broadcasted content, and application of the control messages at locations provided for this purpose by the replacement module.

  • Patent number: 8429685
    Abstract: Methods and systems to provide targeted advertising in a subscription television setting, wherein the households that receive the targeted advertisement may retain anonymity. This may be achieved by marrying an anonymization protocol and infrastructure with a mechanism for STB selection and reporting. This anonymizes the set of households that are selected to play an ad, by ensuring that when an STB meets defined criteria and sends a ‘criteria met’ message (during the selection process) or ‘ad shown’ message (during a validation or counting process) to a head end, an STB or household identifier is not revealed, thus anonymizing the household information from the head end. In addition, this allows the head end to control the ad campaign process by advertising only to those households that meet specified criteria, and to count the number of actual instances in which an ad was displayed.
