Abstract

A technique for storing and selecting media files, such as digital images, video clips or music files, on the basis of symbols (S). The symbols comprise an identifier (11, 422) and visual data (428, 438, 448). For each media file (400) there is association data (402) for associating user-selected symbols (420, 430, 440) with the media file. The association data (402) comprises an identifier (404) of the media file and an identifier (408-412) of each associated symbol. For example, a photograph of a camel family in the New York zoo can be associated with the symbols for camel (420), family (430) and New York (440). The invention simplifies media file classification and retrieval in portable user devices without a full alphanumeric keyboard. The user may obtain more symbols from an external source, such as a dedicated symbol server.

(a) a display for presenting the contents and/or identifier of a media file and the visual data of at least a subset of the plurality of symbols;

(d) a cursor control for user navigation among the presented visual data and for receiving an indication of one or more user-selected symbols;

a software routine and association data for associating the presented media file with the identifier of each user-selected symbol; and

means for transferring to the apparatus one or more symbols in response to a user act.

60. An apparatus according to claim 58, wherein the media file memory area and the association data are within the same detachable memory, whereby the association of media files and symbols is retained if the detachable memory is detached from the apparatus.

61. An apparatus according to claim 58, further comprising means for transmitting a media file and the association data of the media file to an external device.

62. An apparatus according to claim 58, further comprising means for requesting and receiving symbols from an external device.

63. An apparatus according to claim 58, wherein each symbol also comprises a flag indicating whether the symbol is user-modifiable.

64. An apparatus according to claim 58, further comprising a symbol hierarchy, the symbol hierarchy having a root and multiple branches.

65. An apparatus according to claim 64, wherein the apparatus is operable to store at least one symbol in multiple branches.

66. An apparatus according to claim 58, wherein the symbol is coded in a mark-up language.
