System for indexical triggers in enhanced video productions by redirecting request to newly generated URI based on extracted parameter of first URI

摘要

Disclosed are a method apparatus and system for providing addressed network content in connection with a video production. A disclosed method includes receiving a first request from a reproducing apparatus, for example a set-top box, the first request having been extracted from a video production communicated to the reproducing apparatus; determining a second resource identifier responsive to the first request and redirecting the first request wherein a response is provided to the reproducing apparatus. A resource identifier used in the first request is an "indexical' resource identifier in that it specifies a path to be used by a server that is independent (or substantially independent) of content received in response to providing a request to the resource identifier. Determining a second resource identifier may involve creating a resource identifier that includes one or more parameter-parameter value pairs. An apparatus according to the invention may be a server or other computer programmed to handle the indexical request and provide response content. A system according to the disclosure may include the server and a facility for communicating the video production. Additionally disclosed aspects include a method for creating a video production that includes indexical resource identifiers and a method and system for encoding one or more series of resource identifiers in a video production.
