CONTENT BROWSER SYSTEM USING MULTIPLE LAYERS OF GRAPHICS COMMANDS

摘要

Server systems are disclosed that receive content requests and respond with hardware-independent graphics commands instead of, or in addition to, unprocessed content items. The server systems can also generate text information regarding text in the requested content items, and provide the text information to user devices so that the user devices can have knowledge of the text in the content item. The user device can use the text information to handle user interactions with the content item, including copy, paste and search commands and other similar commands. Accordingly, the hardware-independent graphics commands-based representation may provide text interactivity and effects not otherwise available to content representations based on graphics commands or images of content.

主权项

1. A system configured to act as an intermediary between user devices and content servers, the system comprising one or more hardware computing devices, wherein the system is programmed to at least:
receive a request for a content page hosted by a content server; obtain a base file of the content page and a resource referenced by the base file; generate, using a server-side browser application executing on the one or more computing devices, a first set of hardware-independent graphics commands, wherein the first set of hardware-independent graphics commands instructs a client-side browser application to display a representation of at least a portion of the base file; generate, using the server-side browser application, a second set of hardware-independent graphics commands, wherein the second set of hardware-independent graphics commands instructs the client-side browser application to display a representation of at least a portion of the resource; and transmit the first and second sets of hardware-independent graphics commands to the user device over a network.
