摘要： 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

摘要： An information processor determines what media content is currently and/or could be displayed on a primary viewing screen. The information processor then mines other sources of information to obtain associated information. This information can then be accessed by a user as raw data and/or further processed by the information processor and then accessed by the user. Typically, the associated information is displayed on a secondary screen. This allows, for example, an electronic programming guide to be enhanced with additional information.

摘要： 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.

摘要： Robust Header Compression (ROHC) offers a way to compress packet header information for more efficient transmission of data. The compression is achieved through various confidence modes set up by the transmitter and the receiver. The Initialization and Refresh state (IR) is the first state of the compressor. This provides a complete, uncompressed context of the data that is being transmitted. In typically operation, the ROHC compressor will periodically transmit IR packets providing context information allowing the ROHC decompressor to decompress one or more packets following the IR packet. However, under certain conditions such as decompressor start-up, it is possible for the decompressor to miss an IR packet. Exemplary methods and apparatus are described in which a decompressor uses a later-received IR packet to decompress earlier packets for which the decompressor had not received context information.

摘要： A secondary screen device sends information relating to media content viewed on a primary screen device to the primary screen device. The information sent can be altered and/or unaltered information. The secondary screen device can send the information to the primary screen device automatically and/or manually via a user interface on the secondary screen device. In some instances, an intermediate device can be employed to relay the information from the secondary screen device to the primary screen device. The intermediate device can also process the information received from the secondary screen device before sending it to the primary screen device.

摘要： At a receiving device after a power-on or physical channel change, the physical channel is monitored for activity relating to services for which electronic service guide (ESG) data had been previously cached. The ESG data for a service will include some service identification information, such as an interne protocol (IP) address associated with the service. The monitoring of the physical channel for activity related to a service can be done by listening for the IP address associated with the service. If activity is detected, the service is determined to be active and its cached ESG data valid. Service acquisition data included in the cached ESG data is used to present the service to the user. The invention thus allows the presentation of services to the user using cached ESG data as soon as the services are detected to be active, without the need to wait for the reception of fresh ESG data. The cached ESG data of services for which no activity is detected is not used and may be deleted from the cache after a certain period.
摘要翻译： 在上电或物理频道更改后的接收设备处，物理信道被监控与电子服务指南（ESG）数据先前已被缓存的服务相关的活动。 服务的ESG数据将包括一些服务标识信息，例如与服务相关联的国际协议（IP）地址。 可以通过监听与服务相关联的IP地址来完成与服务相关的活动的物理信道的监视。 如果检测到活动，则确定服务处于活动状态，并且其缓存的ESG数据有效。 包含在缓存的ESG数据中的服务采集数据用于向用户呈现服务。 因此，本发明允许一旦检测到服务是活动的，就使用缓存的ESG数据向用户呈现服务，而不需要等待接收新的ESG数据。 没有检测到没有活动的服务的缓存的ESG数据不被使用，并且可以在一段时间后从缓存中删除。
