Abstract
Abstract A method of recognising content signals in a network of computing devices, the method comprising at a first network device in the network, obtaining a content signal distributed to the first network device transforming at least a portion of the content signal into a domain for recognition analysis processing the transformed signal to compute a pattern from the content signal determining an action authorised for the content signal by matching the pattern with a set of stored patterns with corresponding authorised actions and executing the authorised action at the first network.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
72 words
A method of initiating access from a first computer (1004) to a second
computer (1002) via a data communications medium, which method is characterized by : at the first computer (1004), decoding steganographically embedded
address information from audio data (1006), said data representing sampled audio
information rather than ancillary information such as header data; and initiating a link to the second computer (1002) using the address
information decoded from the audio data.
Claim 2
Dependent Claim
14 words
A method according to Claim 1 wherein the address information
comprises a URL address.
Claim 3
Dependent Claim
20 words
A method according to Claim 1 wherein the address information
comprises an index number for use in accessing a database.
Claim 4
Independent Claim
32 words
A method according to any of the foregoing claims in which the second
computer (1002) responds to initiation of the link by sending a data file back to
the first computer (1004).
Claim 5
Dependent Claim
15 words
A method according to Claim 4 in which the data file comprises a
hypertext document.
Claim 6
Independent Claim
40 words
A method according to any of the foregoing claims in which the data
communications medium includes a network to which the first and second
computers (1004, 1002) are coupled, the first and second computers each
having a unique network address.
Claim 7
Independent Claim
29 words
A method according to any of the foregoing claims that further includes
presenting a screen display on the first computer in accordance with
information obtained from the second computer.
Claim 8
Independent Claim
38 words
A method according to any of the foregoing claims in which the linking
is initiated in response to a user clicking on a representation (1006) of said
audio data presented on a screen of the first computer (1004).
Claim 9
Independent Claim
27 words
A method according to any of the foregoing claims in which the second
computer (1002) includes a web page presented by a proprietor of the audio
data.
Claim 10
Independent Claim
58 words
A method permitting object-based linking from a first computer (1004)
to a second computer (1002) via a data communications medium, characterized
by steganographically encoding address information in a portion of an audio
data object (1006) corresponding to audio information to be presented to a
human, said address information being transmitted to initiate a link to the
second computer.
Claim 11
Dependent Claim
33 words
A method according to Claim 10 further comprising including in the
audio data object (1006) a human-perceptible indicium (1012) for indicating the
presence of the steganographically encoded address information in the object
(1006).
Claim 12
Dependent Claim
30 words
A method according to Claim 10 or 11 in which the second computer
(1002) has an address on a network, and the encoded address information
corresponds to said network address.
Claim 13
Dependent Claim
22 words
A method according to Claim 10 or 11 in which the address information
comprises an index number used in accessing a database.
Claim 14
Independent Claim
42 words
A method according to any one of Claims 10 to 13 in which the data
object (1006) further includes an icon presentable to a user in audio or visual
form, the icon being indicative of the presence of steganographically encoded
address information.
Claim 15
Independent Claim
28 words
A method according to any of Claims 10 to 14 in which the data object
(1006) conveys said address information notwithstanding conversion into or out
of digital form.
Claim 16
Dependent Claim
24 words
A computer storage medium having instructions thereon causing a
computer programmed thereby to perform the method of any one of Claims 1 to
