    • Embodiments provide for efficient encoding and rendering of remote graphic displays by applying one or more of the following: (1) field encoding for identifying fields of a graphics set such that commonalities of various fields across different graphics languages are identified; (2) resource caching, which treats heterogeneous resources in a homogeneous way when it comes to storing them; (3) determining the type of encoding for remoting items within a graphics set based upon the types of compression mechanisms supported by a remote device; (4) improving responsiveness by rendering with partially sent resources; (5) a mechanism for determining what portions (if any) of a graphics set should be sent to a remote device and in what order; and (6) use of dedicated resources already on a remote device in order to eliminate the transfer of a resource between a local device and the remote device when rendering such resource.
    • 实施例通过应用以下一个或多个来提供对远程图形显示的有效编码和渲染:(1)用于识别图形集的字段的字段编码,以便识别跨越不同图形语言的各种字段的共同点; (2)资源缓存,它在存储它们时以均匀的方式处理异构资源; (3)基于由远程设备支持的压缩机制的类型,确定用于远程处理图形集内的项目的编码类型; (4)通过部分派发资源提高响应能力; (5)用于确定图形组的哪些部分(如果有的话)应该被发送到远程设备并以什么顺序的机制; 和(6)使用已经在远程设备上的专用资源,以便在渲染此类资源时消除本地设备与远程设备之间的资源传输。

    • A method and system of operating a remote terminal by a terminal server caches representation data of glyphs to be displayed on the remote terminal to reduce the amount of glyph data that have to be transmitted to the remote terminal through a network connection. The glyph caching is performed on a level of text fragments each of which includes a plurality of glyphs. The remote terminal stores a fragment cache for caching fragments and glyph caches for caching individual glyphs. Each entry in the fragment cache contains data indicating where the glyph data for the glyphs of the fragment are stored in the glyph caches. When the terminal server receives a request to display a text fragment on the remote terminal, it checks whether that fragment is cached at the remote terminal. If so, the terminal server sends a fragment index to the client identifying the entry in the fragment cache for that fragment. The terminal client retrieves the information in the fragment cache entry and then retrieves the glyph data for the glyphs of the fragment from the glyph cache, and displays them on the remote terminal. A tuning device uses a counter mode encryption cipher to encrypt counters associated with media content in order to protect the media content when it is sent to requesting device or controller. The encrypted counters are decrypted in order to consume the media content. The controller may send particular direction to the tuning device as to how the media content, encrypted counters, and other associated data are sent to the controller.
