Abstract
Methods and apparatus for retrieving and delivering content in a network. In one embodiment, unique data codes representative of content are generated by a network entity. The data codes are distributed to viewers either via a physical medium or on a display of similar content. The user device requests the content from the network by reading the data code. The requested content is delivered directly to the requesting device or provided to another device identified by the requesting device or user. In another alternative, the unique data code may be representative of the user or subscriber himself. This type of data code may be generated by the network or the device, and enables the user to access content he is entitled to via another device or terminal by delivery of information contained in the data code (or the code itself) to the network.
