Appl. No.:

09/329163

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.

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.

International Classification:

G06F017/60

US Classification:

705/001000

Abstract:

A system and method for managing and enforcing software licenses through automating per-seat software licensing using a “leased license” approach provides vendors with the assurance that purchasers are complying with software licenses while maximizing a customer's use of purchased software licenses. Licenses are automatically enforced by expiring leased licenses and making the expired licenses available again for use by client computers. A system includes a licensing clearinghouse, a license server, clients, and terminal servers. A terminal server assists a client in obtaining a license with an expiration date from a license server, and helps maintain the client's license status through license requests to the license server. Licenses that expire are recycled and made available again to clients. Prior to expiring, licenses are automatically updated during a license update period, and if a license is lost, a temporary license is issued. After the license update period, clients may receive a license update or a new license. Temporary licenses are replaced with permanent licenses that are returned to the available license pool, thus netting out the overall distribution of purchased licenses and assuring that a customer's use of purchased licenses in not lost.
