Patent number: 10608851Abstract: 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.Type: GrantFiled: February 14, 2018Date of Patent: March 31, 2020Assignee: ANALOG DEVICES GLOBAL UNLIMITED COMPANYInventors: Hajime Shibata, Brian Holford, Trevor Clifford Caldwell, Siddharth Devarajan

Patent number: 9043827Abstract: 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.Type: GrantFiled: December 16, 2009Date of Patent: May 26, 2015Assignee: PRIME RESEARCH ALLIANCE E, INC.Inventors: Maxim Rapoport, Charles A. Eldering

Publication number: 20150135210Abstract: 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.Type: ApplicationFiled: January 16, 2015Publication date: May 14, 2015Inventors: Ahmad C. Ansari, Dinesh Nadarajah, David Bruce Hartman
