There are described computer-implemented methods of obtaining a user input. A first such method comprises: (a) providing access to video content, the video content representing a user interface including a plurality of elements for selection by a user; (b) playing a first portion of the video content to the user; (c) detecting a first user interaction occurring in response to the played first portion of the video content; and (d) determining a first element selected by the user based on one or more properties of the detected first user interaction. A second such method comprises: (a) providing access to one or more frames of pre-generated video content encoded in compressed video format; (b) displaying to a user initial video content encoded in compressed video format, the initial video content being based on one or more frames of the pre-generated video content, and the initial video content representing a plurality of graphical elements for selection by a user; (c) detecting a first user interaction occurring in response to the displayed initial video content; (d) determining a first graphical element selected by the user based on one or more properties of the detected first user interaction; (e) in response to the first user interaction, generating new video content encoded in compressed video format based on one or more frames of the pre-generated video content and the one or more properties of the first user interaction; and (f) displaying the new video content to the user. There are also described corresponding apparatuses, computer programs, and computer-readable media.

There is described a method of controlling access to IP streaming content by a plurality of receivers. The method comprises the steps of (a) for each receiver in the plurality of receivers, providing that receiver with access to first control information for that receiver to enable that receiver to access a first portion of the content; (b) identifying a receiver from the plurality of receivers as an identified receiver; (c) updating the first control information so as to provide updated control information for each receiver, the updated control information being associated with a second portion of the content; and (d) configuring each receiver to fetch the updated control information for that receiver. For the identified receiver, the updated control information is invalid such that the identified receiver is unable to fully access the second portion of the content. A server configured to carry out the method is also described.

Controlling access to IP streaming content

There is described a method of enabling a content receiver to access encrypted content, the content receiver forming part of a home network. The method comprises executing, on a device that also forms part of the home network, a key provisioning application. The method further comprises the key provisioning application receiving a key provisioning message and, based on the key provisioning message, providing to the content receiver via the home network one or more content decryption keys for decrypting the encrypted content. There is also described a device arranged to carry out this method. In addition, there is described a content receiver arranged to (a) receive from the aforementioned device, via a home network, one or more content decryption keys for accessing encrypted content; and (b) decrypt encrypted content using the one or more content decryption keys. Related computer programs and computer readable mediums are also described.

Enabling a content receiver to access encrypted content

Computer-implemented systems, methods, and computer-readable media for selecting a sequence of content parts from polymorphic content of an audiovisual presentation based on at least one profile of a user include receiving content information associated with polymorphic content, receiving profile information of a user, and selecting for rendering, from amongst the alternative content parts, a sequence of content parts from the polymorphic content based on at least a portion of the profile information.
