METHOD AND SYSTEM FOR OPTIMIZING METADATA OF AUDIO-VIDEO ASSET IN TELEVISION NETWORK

摘要

The present invention discloses a method and system for optimizing audio-video asset metadata in a television network. Said method comprises: defining at least one audio-video asset with a common attribute as a VOD category; combining a common metadata structure constructed by the common attribute with a specific metadata structure constructed by a specific attribute in the category to form the metadata structure of the category; and generating a metadata file of the category according to said metadata structure, and then packaging the metadata file and an audio-video asset file in the category to generate a general file for sending to an external asset management system. The system of the present invention comprises: a module for defining categories, a module for extending metadata structures and a module generating files. The method and system of the present invention can avoid generating a large amount of redundant data in a metadata file, reduce the workload of a terminal asset provider for information input, and at the same time enhance the transmission efficiency in a network and the information downloading speed of a set top box.
