Abstract: A data processing apparatus includes circuitry that is configured to: receive, from a second data processing apparatus via a web application, an electronic file comprising audio information encoded in a spatial audio format; output the received electronic file for virtualisation of the audio information encoded in the spatial audio format, the virtualisation comprising changing a number of channels of the audio information to allow playback of the audio information via the web application while retaining a spatial audio effect of the audio information; receive a virtualised version of the electronic file comprising the virtualised audio information; and provide, via the web application, the virtualised version of the electronic file.

Abstract: An example method may retrieve a markup language document from an electronic storage device. The markup language document may define a component of an interactive media application and a plurality of resolution dependent parameter sets for the component. The method may continue and determine, using at least one processor, a current resolution of a display device of a playback device and select, using the at least one processor, a parameter set of the plurality of resolution dependent parameter sets for the component based on the current resolution and device. The method may also apply, using the at least one processor, the parameter set to the component; and present, using the at least one processor, the component as part of the interactive media application on the playback device.

Abstract: Disclosed herein is a pet training system that includes a sensing device that is configured to signal a user when a pet is in the proximity of a selected location and a collar module that is configured to be fixed to a collar worn by the pet. A software application is configured to sense a disturbance or permutation in the environmental average magnetic vector, which disturbance is the result of the presence of a localized magnetic field generated by collar module. The pet training system further is configured to warn the user that the pet is within the sensed proximity of the selected location upon confirmation that a determined scaler magnetic state value exceeds a selected scalar threshold value.

Abstract: A retrofit kit for an existing lamp uses its lighting and optical structure to retrofit existing lamp and use the existing lens of the lamp. The new lamp also includes electronic controls which enable remotely or manually controlling the lamp, and also enable other functions.

Abstract: A data processing method for detecting a watermark codeword in a received image signal representing a watermarked image is described. The watermarked image comprises a plurality of signal samples each of which represents a pixel value of the image, to which a watermark codeword coefficient value has been added. The method comprises the steps of low pass filtering the received image signal to generate, for each signal sample, a local mean value, subtracting the local mean from the received image signal to generate a residual signal comprising, for each signal sample, a residual value, and determining, from the residual signal, a local standard deviation for each signal sample. The method also comprises the step of generating, for each signal sample, a watermark strength value providing an estimate of the magnitude with which the watermark codeword coefficient has been added to the received image signal sample.

Abstract: A recording arrangement is provided for applying access control processing to input data content and for recording access-controlled data content on a content storage medium. The recording arrangement comprises an encryption apparatus for encrypting portions of the input data content and an access control memory device operable to securely store information from which a private key of a public key/private key pair associated with a data content recording user or user group is derivable. The encryption apparatus and the access control memory device co-operate to provide means for generating access control data comprising content recorder access control data and default access control data. The default content access control data providing the same level of access to the input data content as the level of access available to the data content recording user/user group. A recording means is provided for recording the encrypted input data content and the content access control data on the content storage medium.

Abstract: A recording apparatus operable to apply access control processing to input data content using a set of one or more content keys and to record access-controlled data content on a content storage medium on which a read-only medium identifier is stored comprises: means for encrypting portions of the data content in dependence upon the set of content keys; means for generating content access control data so that decryption of the information content requires access to the read-only medium identifier, the content access control data comprising at least one encrypted version of a respective subset of the set of content keys; and means for recording the encrypted data content and the content access control data on the content storage medium.

Abstract: A data encryption apparatus operable to apply encryption to input data having at least a format identifying portion and a payload portion comprises means for discriminating between the format identifying portion of the input data and the payload portion of the input data; and means for selectively applying encryption to the input data in dependence upon an output of the discriminating means so as to encrypt at least a part of the payload portion of the input data but not to encrypt the format identifying portion.

Abstract: A data storage arrangement is provided and is operable to apply access control processing to input data in dependence upon a public key of a public key/private key pair. The arrangement comprises an encrypting apparatus and a plurality of removable memory devices connectable to the encrypting apparatus via an interface. The encrypting apparatus stores a local copy of a user director which is identified by a local version identification tag and lists a user identifier and an associated public key for each of a plurality of authorised users. Each removable memory device securely stores an external copy of the user directory. The encryption apparatus also has encryption means for encrypting at least portions of the input data content in dependence on a public key derived from either the local or the external user directory.
