    Abstract: A delivery arrangement for linear TV programs uses SVC in which encoded enhancement layer video data is pre-downloaded to a STB and encoded base layer video data is live broadcasted to the STB at viewing time Pre-downloading of the enhancement layer data is done during off-peak viewing periods taking advantage of an abundance of network bandwidth while reducing bandwidth demand during peak viewing periods by broadcasting only the base layer data The enhancement layer data is downloaded in a modified MP4 file and stored in the STB for later synchronization and combination with the base layer, which is sent to the STB in a real time protocol (RTP) stream The combined base and enhancement layer data is SVC decoded for presentation to the enduser The pre-downloaded enhancement video file may be provided with digital rights management (DRM) protection, thereby providing conditional access to the enhanced video

    Abstract: The present principles provide a method for a personalized mobile broadcast service operator (Service provider) to send content in the form of files with different compression formats in a variable bandwidth channel to one or more users who have access to the same service. Operators providing mobile broadcasts have the option of using residual bandwidth to provide these services. In such services, depending on the amount of bandwidth available for a mobile broadcast, a scheduler can choose to broadcast file content with higher compressed parameters thereby reducing the network footprint of the content file during lower bandwidth situations. A lower compressed format of the same content could then be potentially scheduled to broadcast at a later time when more bandwidth becomes available eventually replacing the highly compressed copy which was received earlier on the client.

    Abstract translation: 本原理提供了一种个性化移动广播服务运营商（服务提供商）以可变带宽信道中的不同压缩格式的文件的形式将内容发送给具有访问相同服务的一个或多个用户的方法。 提供移动广播的运营商可以选择使用剩余带宽来提供这些服务。 在这样的服务中，根据可用于移动广播的带宽量，调度器可以选择以更高的压缩参数来广播文件内容，从而在较低带宽情况下减少内容文件的网络覆盖。 然后可以将相同内容的较低压缩格式潜在地安排在稍后的时间广播，当更多带宽变得可用时，最终替换先前在客户机上接收到的高度压缩的副本。

    Abstract: A Digital Video Broadcasting-Handheld (DVB-H) system comprises a head-end and at least one receiver. The head-end uses the File Delivery over Unidirectional Transport (FLUTE) protocol for transmitting an electronic service guide (ESG) and content to the receiver. The receiver determines a time delay for receiving content as a function of a value of a PublishedStartTime parameter from the ESG and the actual time the receiver receives the content. Using this time delay, the receiver forms a time estimate for receiving selected content as a function of a value of a PublishedStartTime parameter from the ESG for the selected content and the determined time delay. The receiver then performs power, management such that during those intervals of time that the receiver is not expected to receive the selected content the receiver can reduce power.

    Abstract translation: 数字视频广播 - 手持（DVB-H）系统包括头端和至少一个接收器。 头端使用文件传输单向传输（FLUTE）协议​​将电子服务指南（ESG）和内容发送到接收器。 接收机确定接收内容的时间延迟，作为来自ESG的PublishedStartTime参数的值和接收者接收内容的实际时间的函数。 使用该时间延迟，接收器形成用于接收所选内容的时间估计，作为来自针对所选内容的ESG的已发布时间参数的值的值以及所确定的时间延迟。 然后，接收机进行功率管理，使得在接收机不期望接收所选择的内容的那段时间间隔期间，接收机可以降低功率。

    Abstract: A search engine performs searches on displayed information to facilitate in limiting the search results and increasing relevancy. The search engine allows user inputs to influence a search boundary and/or a search result. The search boundaries and/or search results can also be influenced by social networking information and the like. The search results can be dynamically filtered by the search engine as the user enters in their search criteria. The searched information is limited to what is visually seen by a user on a screen/display device. This significantly reduces the displayed results and lets the user instantly see what their search parameters will yield.

    Abstract: A system and method of identifying and providing content to a user is described. The method is performed by a controller with an internet interface. A controller receives electronic program guide data, the electronic program guide data being selectively displayed on a primary display device. An attribute processor parses the received electronic program guide data to identify at least one program description attribute for a currently tuned program. A content processor searches the received electronic program guide and detects at least one further program having the identified at least one program description attribute. The content processor identifies the at least one further program as recommended content in step and a user interface generator generates, a user interface display including the recommended content user interface including a user selectable data item representing the recommended content for display on a secondary display device different from the primary display device.
