    摘要: Improved techniques for managing image data associating with asset records in an electronic media programs catalog list between a media server (e.g., a video-on-demand server) and a terminal device or a client system (e.g., a set-top box) is disclosed. The catalog list is created by a module and displayed on a terminal device. Each of the asset records represents a media program that the user can browse. Each of these media programs may associate with a graphical image data, which is also displayed, when the user browses at that particular record. The image data are stored on the media server with a portion duplicated in an image windowing cache on the terminal device. The image windowing cache is intelligently filled by a predictive pre-fetch operation in the background while the user browses a particular record. The predictive operation ensures additional n images are pre-fetched in user scroll direction.
