摘要： The present invention provides methods, devices and systems for dynamically adjusting transcoding parameters so as to increase the benefits of transcoding. Methods of adaptation are designed to cope with the variability of network characteristics and of the size of transcoded images. The invention also provides a method and apparatus to enable the transcoding proxy to adjust a quality-size tradeoff on a per-image and/or a per-client basis. The adaptive transcoder chooses different parameters for each object, and provides performance improvements. The invention further provides a general framework for making policy decisions taking into account available bandwidth, content and type of image, and user preferences. The invention also includes methods for generating feedback about the choice of optimal transcoding parameters to the user.

摘要： The memory space (often in the form of cache) in a system (e.g., an Internet proxy or web browser) is conserved by saving low resolution versions of data objects when the full resolution version is removed (e.g., due to age, using a least recently used (LRU) replacement policy) in order to create space for new objects. This provides for efficient use of the memory space. In many situations, the low resolution version of the data object is of adequate quality for usage. Further, even when this is not the case, it can be useful to quickly obtain a low resolution version and then with some delay, obtain the full resolution version at the user or application's request. Particular advantageous embodiments of methods, apparatus and article of manufacture implementing the invention are presented.

摘要： The present invention presents methods and apparatus supporting acceleration of networked applications by means of dynamic distributed execution and maintenance. It also enables management and administration of the distributed components of the networked applications from a responsible point of origination. The method and apparatus deploys a plurality of proxy servers within the network. Clients are directed to one of the proxy servers using wide area load balancing techniques. The proxy servers download programs from backend servers and cache them in a local store. These programs, in conjunction with data stored at cached servers, are used to execute applications at the proxy server, eliminating the need for a client to communicate to a backend server to execute a networked application.
