摘要： 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.

摘要翻译： 由终端服务器操作远程终端的方法和系统缓存要在远程终端上显示的字形的表示数据，以减少必须通过网络连接发送到远程终端的字形数据量。 字形缓存在文本片段的级别上执行，每个文本片段包括多个字形。 远程终端存储缓存用于缓存单个字形的片段和字形缓存的片段缓存。 片段缓存中的每个条目都包含指示片段的字形的字形数据存储在字形缓存中的位置的数据。 当终端服务器收到在远程终端上显示文本片段的请求时，它检查该片段是否在远端终端缓存。 如果是这样，终端服务器向客户端发送一个片段索引，标识该片段的片段高速缓存中的条目。 终端客户端检索片段缓存条目中的信息，然后从字形缓存检索片段的字形的字形数据，并将其显示在远程终端上。 调谐设备使用计数器模式加密密码来加密与媒体内容相关联的计数器，以便在发送到请求设备或控制器时保护媒体内容。 加密的计数器被解密以便消耗媒体内容。 控制器可以向调谐设备发送关于如何将媒体内容，加密的计数器和其他相关联的数据发送到控制器的特定方向。
