摘要： A system for facilitating production of information material comprises a plurality of metadata nodes operable to process metadata describing the content of information material, and a data communications network for providing a facility for communicating the metadata between the metadata nodes. The metadata is represented as metadata strings describing the content or attributes associated with the information material. The metadata string includes a Uniform Resource Identifier (URI) providing an address of a storage location of an associated metadata resource. The metadata string is communicable separately from the information material via the network and the associated metadata resource is accessible via the network using the resource identifier. The metadata string can be arranged to provide an indication of parameters describing the information material and identifiers such as UMIDs or the like which facilitate navigation of the information material. The associated metadata resource can be arranged to provide any further metadata having a substantial volume. By describing the associated metadata resource with a URI contained within the metadata string, the metadata resource is accessible from, for example a web browser. Accordingly the metadata resource does not need to be communicated with the metadata string, thereby substantially reducing a bandwidth requirement or data communications traffic required on the data communications network.

摘要： A data structure for representing metadata describes the content of at least one shot or sub-shot of information material. The data structure comprises a volume identification defining a data carrier on which the information material is contained, at least one shot identification defining the shot or sub-shot within the material, and at least one type of metadata associated with the content of the shot or sub-shot. The volume identification is arranged at a first hierarchical level and the shot identification is arranged at a lower hierarchical level and the metadata describing the shot is arranged with respect to the shot hierarchical level. The data structure provides an efficient facility for communicating metadata between metadata nodes including application programs which use the metadata. The metadata is identified on the basis of a shot and volume on which the information material which the metadata describes is contained. By arranging the volume identifier at a first hierarchical level, the shot identifier at a lower hierarchical level and the metadata related to the shot or sub-shot within the shot level, a systematic and compatible format for interrogating and retrieving metadata is provided.
摘要翻译：用于表示元数据的数据结构描述了信息材料的至少一个镜头或子镜头的内容。数据结构包括定义其上包含信息材料的数据载体的卷标识，定义材料内的拍摄或子画面的至少一个拍摄标识，以及与拍摄的内容相关联的至少一种类型的元数据分手。体积识别被布置在第一层次级别，并且镜头识别被布置在较低层级，并且描述镜头的元数据相对于镜头层级设置。数据结构提供了在元数据节点之间传送元数据的有效设施，包括使用元数据的应用程序。元数据基于包含元数据描述的信息材料的镜头和音量来识别。通过将音量标识符排列在第一层次级别，提供较低层次级别的镜头标识符和与拍摄级别内的镜头或子镜头相关的元数据，提供用于询问和检索元数据的系统兼容格式。

摘要： Video data compression apparatus for compressing images of an input video signal on a block-by-block basis comprises a block analyser for analysing each block of an image to be compressed to detect a degree of difference between pixels within that block; a data quantity allocator for allocating target output data quantities for the compression of each block, the target data quantities being dependent on the detected degrees of pixel difference of the blocks; and a data compression encoder for compressing each block in accordance with the target output data quantity associated with that block.
