Abstract: An outdoor lighting network (OLN) is disclosed as a supplementary or contingency communications infrastructure for smart city systems. The OLN may integrate light points within the network as receivers which are switched from a standard OLN communication protocol to a D2D based protocol upon disruption of a primary smart city systems communications network, wherein each communication protocol includes a respective message prioritization method. Aspects of the disclosure additionally includes methods and apparatus for implementing an outdoor lighting network which can act, in cases of primary communication failure, as a D2D network in order to pass messages from smart city system field devices, through the converted D2D OLN network and to a smart city system central manager for proper handling and distribution of the smart city system field device communications.

Abstract: Multiple luminaires are mounted contiguously in a plane, along a straight line or following a one or two dimensional contour, but with a visible periphery between each adjacent pair. A different signal is embedded into the visible illumination emitted by each luminaire, which an image processing module can detect from one or more images captured by a camera. An angle-dependent mask is arranged to cover at least the periphery between adjacent luminaires, such that an appearance of the periphery when viewed from the environment through the mask varies as a function of viewing angle, becoming less visible at greater values of viewing angle (being the angle between a corresponding viewing direction and a normal to the plane, line or contour). The image processing module distinguishes between the different signals based on the periphery being visible when captured from less than a predetermined value of the viewing angle.

Abstract: Apparatus for controlling one or more light sources to emit coded light which is modulated to embed a signal. The apparatus comprises: an interface for receiving information relating to two or more exposure times of one or more cameras on one or more devices, the one or more cameras being operable to detect the coded light based on the modulation; and a controller configured to select at least one property of the modulation, based on the information, such that the modulation is detectable at each of said two or more exposure times.

Abstract: The present invention relates to a method and a system for performing digital rights management. The idea of the invention is that a master right associated with a content is stored at a first authorized device (211). An authorized device is a device which can be considered trusted and performs actions with contents according to the associated rights. These devices enforce rights that are bound to contents, and perform the security tasks of the DRM system employed. A subright is derived from the master right, which subright controls what type of access a second authorized device (261) is given to the associated content. Finally, the subright is distributed to the second authorized device, given that the second device complies with predetermined distribution criteria associated with the master right. The device distributing the subright authenticates the device which is to receive the subright, ensuring that the second device can be trusted.

Abstract: Disclosed are a method, a controlling device (110), a controllable device (130) and an arrangement (100) for communicating a command from the controlling device (110) to the controllable device (130). A watermark is generated comprising the command, and embedded in a signal (120) representing an audio or video fragment. The controllable device (130) receives the signal (120) comprising the command, and decodes and executes the command therefrom. Also disclosed is a method of presenting an advertisement which involves sending a command related to presenting the advertisement using the above-mentioned method.

Abstract: A receiving device for securely storing a content item on a storage medium is disclosed. The content item is stored in a secure format, and has an associated license file. The license file is encrypted using public key associated with a group of playback devices, so that each playback device in the group can decrypt the license file and play the content item, but devices outside the group cannot. A playback device can provide a device-specific public key to a Content Distribution Management System (CDMS). The CDMS then returns the secret key for the group encrypted with the public key of the playback device. The playback device then securely obtains the secret key of the group and is subsequently able to decrypt the license file.

Abstract: An audio signal processing device includes a signal supply for supplying speech and music signals via one or more input channels. The device further includes a signal separator for separating the speech and music signals. A first converter converts the music signals into desired virtual widened signals from one or more input channels. A signal combiner used to combine the speech signals with the widened music signals.

Abstract: A method of increasing functionality of a product (121) made by a manufacturer (120). A specification of an additional feature (122) is supplied to the manufacturer (120) for inclusion into a disabled state into the product (121). The technology provider (100) receives an activation payment from a third party wishing to make use of the additional feature (122).The manufacturer (120) may share this activation payment with the manufacturer (120). The product (121) can for instance be an integrated circuit, a software program and a hardware apparatus, but may also be a specification of a standard, in which case the manufacturer (120) comprises a standardization body responsible for drafting said specification.

Abstract: A receiving device (110) for securely storing a content item (102) on a storage medium (111). The content item (102) is stored in a secure format, and has an associated license file. The license file (141) is encrypted using public key associated with a group of playback devices (120, 121), so that each playback device (121) in the group can decrypt the license file (141) and play the content item (102), but devices outside the group cannot. A playback device (121) can provide a device-specific public key to a Content Distribution Management System (CDMS). The CDMS then returns the secret key for the group encrypted with the public key of the playback device (121). The playback device (121) then securely obtains the secret key of the group and is subsequently able to decrypt the license file (141).

Abstract: A method of enabling disintermediation in a business model, as well as an arrangement (100) therefor. Extra information related to the business model is embedded in content such as music, which is then distributed via a third party (202) to a rendering device (204). The rendering device (204) generates an audible signal (120) that can be picked up by a receiver (220) such as a mobile phone. The receiver (220) processes the signal (120) to obtain the embedded information, which is then used in the course of the business model.

Abstract: Distribution of digital information, in particular audio, is controlled as follows. An information carrier (11) like a CD is distributed which has at least part of the digital information encrypted using an encryption key. A decryption key corresponding to the encryption key is also distributed to the user, e.g. on a reserved area of the CD. The user (32) reproduces the audio on a player (31), which decrypts the information using the key. However, at least part of the information is only reproduced after a Personalized Access Code PAC (40) is received by the player. The PAC is generated at a remote access center (33), e.g. an internet site. A database (34) connected the center and a player memory hold a player identifier and secret player key. The user transmits the player identifier and an information identifier identifying the CD to the access center, and the access center calculates the PAC using the identifier and the secret player key.
