摘要： A method of controlling delivery of video programs from video distribution equipment to video receiver devices includes receiving messages at the video distribution equipment from a mobile terminal operated by a user. The messages contain user defined identifiers that are associated with equipment identifiers of different ones of the video receiver devices. The user defined identifiers are stored associated with the equipment identifiers in a subscriber account. Delivery of video programs from the video distribution equipment to the video receiver devices is controlled in response to commands received from the mobile terminal which request delivery of identified video programs to identified ones of the user defined identifiers. Related video distribution equipment and mobile terminals are disclosed.

摘要： A method for enforcing entitlements includes configuring a wide variety of entitlements at a server; determining applicable combination of entitlements for a given client request; sending entitlements to the requesting client securely; handling entitlement information securely on a plurality of client devices at run time; storing entitlement information securely on a plurality of client devices for offline use; and enforcing entitlements on a plurality of client devices. The method employs manipulation of manifest files by a proxy that may be included in the client device or located in the network.

摘要： A method is provided for managing key rotation (use of series of keys) and secure key distribution in over-the-top content delivery. The method provided supports supplying a first content encryption key to a content packaging engine for encryption of a first portion of a video stream. Once the first content encryption key has expired, a second content encryption key is provided to the content packaging engine for encryption of a second portion of a video stream. The method further provides for notification of client devices of imminent key changes, as well as support for secure retrieval of new keys by client devices. A system is also specified for implementing a client and server infrastructure in accordance with the provisions of the method.

摘要： A system and method for effectuating fast channel change in an adaptive streaming environment. A plurality of adjacent channels may be predicted relative to a current streaming channel engaged by a client device. Upon prioritizing the adjacent channels, the client device may be configured to pre-fetch metadata and initialization information for a subset of the prioritized adjacent channels based on bandwidth conditions, video player buffer status, etc. When a channel is changed, the client device is operative to use the pre-fetched data to quickly obtain encoded media content at a select bitrate for rendering.

摘要： A recording device and a method are described herein that provide a network-based personal video recording service utilizing adaptive bit rate technology for a plurality of users. In operation, the recording device records at a minimum a single bit rate (one set of segmented files) of the broadcast content within each user's network personal video recorder storage unit. Plus, the recording device stores the other bit rates (remaining sets of segmented files) in a central storage location or some other storage location.

摘要： A method of managing bandwidth allocation across a video pipe that delivers both streaming adaptive bitrate (ABR) content and progressive download ABR content includes receiving a designation of a congestion boundary within a video pipe, the congestion boundary designating a first percentage of the video pipe that is to be used for streaming ABR content when congestion exists on both sides of the congestion boundary, wherein a remaining percentage of the video pipe is to be used for progressive download ABR; allocating bandwidth for streaming ABR content, wherein the gateway device can allocate for streaming content only that portion of the remaining percentage of bandwidth that is not requested for progressive download content; and allocating bandwidth for progressive download content, wherein the gateway device can allocate for progressive download content only that portion of the first percentage of bandwidth that is not requested for streaming content.

摘要： Antenna package structures are provided to implement wireless communications packages. For example, an antenna package includes multilayer package substrate, a planar antenna array, antenna feed lines, and resistive transmission lines. The planar antenna array includes an array of active antenna elements and dummy antenna elements surrounding the array of active antenna elements. Each active antenna element is coupled to a corresponding one of the antenna feed lines, and each dummy antenna element is coupled to a corresponding one of the resistive transmission lines. Each resistive transmission line extends through the multilayer package substrate and is terminated in a same metallization layer of the multilayer package substrate.
