1. A computer-implemented method of using a paper document to retrieve multimedia information stored in a multimedia document in electronic form, the method comprising:
- receiving a first signal indicating selection of a first user-selectable identifier from one or more user-selectable identifiers printed visibly on the paper document, each user-selectable identifier being associated with a portion of the multimedia document, each user-selectable identifier encoding position information that specifies where in the multimedia document its associated portion is;
responsive to receiving the first signal, retrieving a portion of multimedia information stored in the multimedia document using position information encoded in the first user-selectable identifier; and
outputting the portion of the multimedia information corresponding to the first user-selectable identifier using an output device.

Abstract
The present invention provides techniques for generating a printable representation of multimedia information that can be printed on a paper medium to provide a paper-based interface for the multimedia information. According to the teachings of the present invention, the paper document generated by printing the printable representation on a paper medium also provides an interface for accessing or retrieving multimedia information in electronic form. The paper document may thus be used as an indexing and retrieval tool for retrieving multimedia information.

15. A computer-implemented method of using a paper document to retrieve multimedia information stored in a multimedia document in electronic form, wherein one or more user-selectable identifiers are printed on the paper document, the method comprising:
-
receiving a first signal indicating selection of a first user-selectable identifier from the one or more user-selectable identifiers printed on the paper document, each user-selectable identifier being associated with a portion of the multimedia document, each user-selectable identifier encoding position information that specifies where in the multimedia document its associated portion is; responsive to receiving the first signal, retrieving a portion of multimedia information stored in the multimedia document using position information encoded in the first user-selectable identifier; and outputting the portion of the multimedia information corresponding to the first user-selectable identifier using an output device, wherein the position information includes time information that reference points in time in the multimedia information, wherein retrieving the portion of multimedia information stored in the multimedia document corresponding to the first user-selectable identifier comprises; determining a first time corresponding to the first user-selectable identifier; and obtaining a portion of the multimedia information stored in the multimedia document occurring from the first time in the portion of multimedia information corresponding to the first user-selectable identifier.
