Method and apparatus for moving content to mobile devices
First Claim
1. A method of referencing a map to the coordinate space of a positioning system, the method comprising:
- for each of a plurality of real-world positions, associating the location of the real-world position in a coordinate space of the map, with a location in the coordinate space of the positioning system determined by taking at least one positioning-system reading at the real-world position; and
using the associated locations to determine a master transform for converting relative location information between said coordinate spaces, said relative location information serving to specify a location relative to the already-known locations of said plurality of real-world positions.

Abstract
A method and apparatus is provided for moving content to a mobile device (2). A data item (34) of a predetermined type is received at a first device (14), the data item (34) including a content URI for fetching content associated with the data item. Upon detecting that the data item (34) is of the predetermined type, the first device (14) generates a symbol (40) representing at least: a local address of a content-retrieval device (14) on a local wireless network, and an explicit or implicit identifier of the content associated with the data item. The symbol (40) is then read using the mobile device (2). The mobile device (2) decodes the symbol and transmits a request, containing the content identifier, to the content-retrieval device (14). On receiving the request, the content-retrieval device (14) uses—the content identifier in the request to obtain that content, and replies to the request with the obtained content.

18. Portable apparatus comprising:
-
a positioning system for deriving a location in a coordinate space of the positioning system corresponding to a current real-world position of the apparatus; a user interface arranged to display a map and enable locations in the coordinate space of the map to be selected by/identified to a user; a memory for storing locations in both said coordinate spaces; and a processing arrangement arranged to associate the location in the coordinate space of the positioning system of a said current position of the apparatus with a corresponding location in the map coordinate space for a plurality of different said current positions, the processing arrangement being further arranged to use the associated locations to determine a master transform for converting relative location information between said coordinate spaces, said relative location information serving to specify a location relative to the already-known locations of said plurality of current positions.
