International Classification:

G06T 1100

US Classification:

345467, 345557

Abstract:

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.

Abstract:

The present invention is directed to appropriately rendering terminal server graphical data at multiple client side monitors. In some embodiments, a client sends client side monitor configuration for a plurality of monitors to a server. The server simulates a virtual desktop for the plurality of monitors based on the client side monitor configuration. Graphical data generated for the simulated virtual desktop is converted to drawing commands and returned to the client for rendering. In other embodiments, a separate terminal server session is established for each of a plurality client side monitors. Drawing commands for a specified client side monitor is sent from the terminal server to the client over the corresponding session for the client side monitor.

US Classification:

345501, 345418, 345522, 345650, 719328

Abstract:

A portable graphics encoder connects with one or more protocol decoder devices based on a particular communication protocol. The portable graphics encoder is not specific to any particular operating system. The portable graphics encoder receives protocol decoder device commands such as input instructions that determine higher-level graphics commands that are sent to the one or more protocol decoder devices. The higher-level graphics commands are extracted from graphics sources such as application programs. The portable graphics encoder encodes the higher-level graphics commands according to a format defined by the communication protocol, and the encoded higher-level graphics commands are sent to the one or more protocol decoder devices.
