    摘要： A method of instructing a receiver/decoder to perform an action is described. The method comprises transmitting a command to the receiver/decoder via a broadcast system, the command instructing the receiver/decoder to perform the action. Apparatus for generating a message comprising a command for transmission in a broadcast system, a corresponding receiver/decoder, and a message for tranmission in a broadcast system, the message comprising a command to instruct the receiver/decoder to perform an action, are also described.

    摘要： The application describes a method of referencing content in an application. The method comprises, for a content element, creating a reference to the content element and associating that reference with the content element. This enables the content (for example, text or images) to be dissociated from other features related to content; for example, its presentation on the screen. In this way, control over presentation may be achieved separately from control of the content itself. In an example, a Content Provider 402 provides referenced content to an Operator 404. A Programme Provider 400 sends referenced scenarios to the Operator 404. The Operator 404 resolves the reference and sends data for broadcast by the Broadcaster 406.

    摘要翻译： 该应用程序描述了在应用程序中引用内容的方法。 对于内容元素，该方法包括创建对内容元素的引用并将该引用与内容元素相关联。 这使得内容（例如，文本或图像）可以与其他与内容相关的特征分离; 例如，它在屏幕上的呈现。 以这种方式，对呈现的控制可以与对内容本身的控制分​​开实现。 在一个示例中，内容提供商402向运营商404提供引用内容。节目提供商400将所引用的场景发送给运营商404.运营商404解析该参考并发送由广播者406广播的数据。

    摘要： A client for handling a video session includes a memory and a processor coupled to the memory. The memory stores a first video frame that includes first video data, a first video sub-frame comprising second video data that is different from the first video data, and a second video sub-frame comprising third video data. The processor generates a second video frame using the first video frame and the first video sub-frame, wherein the third video data is different from the video data of the second video frame. The processor further generates a third video frame using the second video frame and the second video sub-frame, and displays the first video frame.

    摘要： To easily cope with change in methods of media. A CPU 22 controls a front end 21 including a tuner 41, a demodulator 42, and an error corrector 43 indirectly with a common control command, independent of a zone and a transmission medium. That is, an application program 22A of the CPU 22 creates a control command based on a command set defined in advance, and sends it out to the front end 21 via an interface 22B. The control application 40B of the front end 21 converts the control command transferred via the interface 40A into a data format recognizable for the tuner 41, the demodulator 42, and the error corrector 43, and transfers it to a driver 40C. The driver 40C controls each processing unit based on the control command.

    摘要： EPG services (40) are provided, which enables a device (20) such as a computer, a set top box or the like to collect EPG data from multiple EPG data providers or sources (70). The EPG data is collected at the device (20) by EPG loaders (60). Each EPG loader (61, 62, 63) collects EPG data from a particular source (74, 75, 76). The EPG loaders (60) deliver the EPG data to a writer module (43), which performs scaling and formatting functions to the EPG data. The writer module also stores the scaled and formatted EPG data in a database or other storage (42). The writer module (43) may also be implemented by chaining EPG loaders (60) in a priority scheme. However, EPG loader interaction reduces independence and forces more rigid interface and implementation constraints upon the design of EPG loaders (60). Once stored, applications (22) gain access to the EPG data through a control module (41). The control module (41) provides the accessed EPG data to the applications (22). EPG services (40) function to isolate the operation of the applications (22) from the EPG data sources. Because the EPG data is stored by the writer module (43) and accessed by the control module (41), the applications (22) and EPG data sources (20) can change independently of one another without having an effect on the ability of EPG services (40) to collect and provide access to EPG data.
