A METHOD FOR GENERATING DTV CONTENT DATABASE

摘要

The method for generating DTV content database has for a novelty that for each DTV content which belongs to the VoD or EPG database, quality level (107) is assigned, based on reliability level (105) of metadata (100) of DTV content. Also, reliability level (109) is assigned to the DTV content, based on confidence levels (103), which are empirical predetermined. Metadata (100) are collected in phase (200) using searching mechanisms, which takes base informations as filter inputs, after that, type of metadata is determined, and quality level (102) of metadata is estimated, using criteria according to previously determined type. The method also includes process of metadata (100) confidence validation (104), where is quality level (105) assigned to the metadata, based on confidence level (103), and these marks are used as filter inputs, where is content quality level (107) estimated in phase (106), according to the certain criteria. In DTV content confidence validation (108), confidence level (109) is assigned to the every DTV content, using previously determined quality level (107) of DTV content and confidence levels (103). In phase (202), using confidence levels (109) of contents, valid contents are added to the existing DTV content database, which is available to the users on every target device.
