Abstract
A method and apparatus for decompressing and communicating a predetermined amount of data in a client-server environment in which the server relays communications between a client web browser and at least one shared peripheral device. Compressed data from the peripheral device is decompressed on-the-fly, and is packaged and transmitted to the client web browser. Appropriate logic is provided to ensure that the web browser receives an expected amount of decompressed data regardless of the amount of compressed data provided by the peripheral device. Moreover, logic is provided to reduce the amount of resources required in decompressing the data.
