Abstract: A method of providing automatically verifiable trust in a content resolution process in which a PDR resolves a content reference identifier (CRID) identifying a content item using a resolution authority record (RAR) to obtain a locator identifying a location where the PDR can obtain the content item. Preferably, the measure comprises computing a digital signature over at least part of the contents of the CRID, the locator and/or the RAR. The method may also comprise encrypting at least a data portion of the CRID, RAR or locator. Digital rights needed to access the content item can be provided with the CRID, RAR or locator.

Abstract: When the user views the information available on a program (in a Personal Video Recorder), the keywords that determine whether a program will be recorded are accentuated. This can be done by using the size of the text or by using colors or any other kind of varying accentuation i.e. encircled or blinking text. This makes it easy for the user to identify the keywords used in their personalized profile. Additionally the user can navigate between keywords and change the accentuation of the keywords, to indicate a rating (in multiple levels) of the keyword.

Abstract: A method of creating an audio/video stream comprises multiplexing a video component, an audio component, a content reference identifier, and a semantic data packet containing information on the relationship between the video component and the content reference identifier. Apparatus for receiving the audio/video stream, and apparatus for transmitting the audio/video stream are disclosed.

Abstract: A method of creating an audio-video stream comprises multiplexing a video component, an audio component, a content reference identifier, and a semantic data packet containing information on the relationship between the video component and the content reference identifier. Apparatus for receiving the audio-video stream, and apparatus for transmitting the audio/video stream are disclosed.

Abstract: A method of acquiring repetitively broadcast data comprises acquiring the data in fragments, acquiring a document comprising information on the fragments, examining the information, and re-acquiring the fragments according to the information.

Abstract: A method of enabling a user to obtain a query result in a data network is provided taken latency problems of decentralised networks comprising a number of entities into account. The method comprises the steps of sending a query from a requesting entity to a number of further entities in the data network, receiving responses from at least some of the further entities and determining an initial relative response time for an initial group of said responses, determining a current relative response time for further incoming responses, comparing the initial relative response time with the current relative response time, and presenting the responses to a user of the requesting entity when the difference between the initial relative response time and the current relative response time exceeds a relative response-time parameter Further, a computer readable medium and a device provided with or for carrying out such methods are provided.
