    摘要： In connection with the supply of data tokens identifying the forthcoming delivery of audio/video content, a method for obtaining content access data relating to forthcoming content is provided, together with a method for supplying such data and apparatus supporting the methods. Where a remote resolution utility (12) is available to supply access data, in the form of time and channel for broadcast, for example, in response to supply of an appropriate content identifier, the method comprises capturing, other that directly via the mechanism by which content is to be delivered, of a content identifier (16) for an item of content; determining from said content identifier said resolution utility; transmitting the captured content identifier to said resolution authority; and receiving the access data returned by said resolution utility.

    摘要： A method and apparatus are provided for generating bridge segments to enable editing jumps to be made from one A/V segment to another while handling timing and frame constraints imposed by the A/V segment compliance with coding conventions, such as MPEG. The bridge segment is constructed by copying data from the two sequences to be bridged, with some demultiplexing, decoding, remultiplexing and re-encoding of this data to maintain the validity of the edited data stream. Different procedures in terms of copying and/or re-encoding are applied in dependence on the picture encoding types at the source and destination of the edit via the bridging segment.
