CONFERENCE PROCEEDINGS FREE ACCESSWe propose a new method to reduce the blocking artifacts to apply at the decoding stage of MPEG2 video bitstream. The proposed method specifies the area where the blocking artifacts occur by utilizing the information obtained from bitstream such as DCT coefficients and motion vectors. Then it reduces the blocking artifacts of the decoded picture with spatial filtering to the area where the blocking artifacts occur. We confirm that a picture quality is significantly improved using the proposed method with the computer simulation.View full abstractDownload PDF (1016K) -

CONFERENCE PROCEEDINGS FREE ACCESSA video disk recorder requires disk drives to have wide bandwidth and a quick response. There are many studies of this requirements, however, those studies assume that a disk drive has no defective blocks. In practical, there are some problems to access to a data segment including some defective blocks, because access time to such a data segment is longer than usual. This paper describes a delay behavior of access time caused by defective blocks, and an effective block reassigning method of disk drives for video disk recorder.View full abstractDownload PDF (505K) -

CONFERENCE PROCEEDINGS FREE ACCESSNHK Archives is scheduled to open in 2003. The retrieval system, which allows stored video programs to be searched and previewed by using PCs, is its essential function. We have been studying a retrieval system for video archives. The core of the system is a hierarchical storage management system(HSMS), which makes use of a combination of hard disks for high-speed data access and low-cost tape streamers with large storage capacity. We constructed an experimental retrieval system using the proposed HSMS, and tested its functions. The HSMS was found to be effective for the retrieval system for a large amount of video archive material.View full abstractDownload PDF (855K) -

CONFERENCE PROCEEDINGS FREE ACCESSWe have developed the program that makes broadcasting cuesheets. Using this program, TV-Asahi networks are possible to browse broadcasting cuesheets on WWW. In this paper, we describe the design of broadcasting cuesheets, which is made by the program we developed and the transmission system, how TV-Asahi networks can browse broadcasting cuesheets as soon as we had made.View full abstractDownload PDF (957K) -

CONFERENCE PROCEEDINGS FREE ACCESSAn ultra-high-sensitivity HDTV color camera has been developed using 3 proximity focused image intensifier tubes of large image size(useful area 40mm DIA.) and 3FIT CCDs of 2/3-inch 2M-pixels. It has a high sensitivity of 3000 times as same as conventional HDTV CCD cameras. It makes possible to shoot high-quality realtime-images of meteor nebulae and galaxies.View full abstractDownload PDF (766K) -
