摘要： A method of combining an interactive user interface for generating a blended output that includes the interactive user interface and one or more supplemental images. At a client device remote from a server, a video stream that contains an interactive user interface is received from the server using a first data communications channel configured to communicate video content, and a command that relates to an interactive user interface is transmitted to the server. In response to the transmitting, an updated user interface is received from the server using the first data communications channel, and one or more supplemental images for supplementing the interactive user interface are received using a second data communications channel different from the first data communications channel. The updated user interface and the one or more supplemental images are blended to generate a blended output, which is transmitted toward the display device for display thereon.

摘要： Switched digital television programming for video-on-demand and other interactive television services are combined utilizing a class-based, multi-dimensional decision logic to simultaneously optimize video quality and audio uniformity while minimizing latency during user interactions with the system over managed networks such as cable and satellite television networks. A group of user sessions are assigned to a single modulator. The user sessions include data in a plurality of classes, each class having a respective priority. In response to a determination that an aggregate bandwidth of the group of user sessions for a first frame time exceeds a specified budget, bandwidth is allocated for the group of user sessions during the first frame time in accordance with the class priorities. The group of user sessions is multiplexed onto a channel corresponding to the modulator in accordance with the allocated bandwidth and transmitted over a managed network.

摘要： System and methods are provided to cache encoded graphical objects that may be subsequently combined with other encoded video data to form a data stream decodable by a client device according to a format specification. Paint instructions relating to a graphical object are sent from a layout engine to a rendering library. A shim intercepts these instructions and determines whether the graphical object already has been rendered and encoded. If so, a cached copy of the object is transmitted to the client device. If not, the shim transparently passes the instructions to the rendering library, and the object is rendered, encoded, and cached. Hash values are used for efficiency. Methods are disclosed to detect and cache animations, and to cut and splice cached objects into encoded video data.
摘要翻译：提供了系统和方法来缓存编码的图形对象，其可以随后与其他编码视频数据组合，以形成可由客户端设备根据格式规范解码的数据流。与图形对象有关的绘制指令从布局引擎发送到渲染库。垫片拦截这些指令，并确定图形对象是否已经被渲染和编码。如果是，将对象的缓存副本传输到客户端设备。如果没有，则垫片将指令透明地传递到渲染库，并且对象进行渲染，编码和缓存。哈希值用于效率。公开了用于检测和缓存动画的方法，以及将缓存的对象剪切和拼接成编码的视频数据。
