—High splitting, optically amplified, passive optical networks (SuperPONs) are investigated in terms of redundancy provision and protection mechanisms. Options for redundancy, including the important special case of dual homing, are detailed, and it is determined as to which of these options (duplication of the feeder and first distribution section, and + 1(More)
In this paper, by considering the multiple spatial-temporal characteristic of visual perception system, we propose a novel home video attention analysis method. Firstly, each frame of the video is segmented into regions which are more informative than pixels and image blocks. Then the saliency of each region is analyzed by combining static, motion and(More)
The new trend of online advertisement is in-image advertising, which is facing the risk of being intrusive. Several works have been done to reduce the intrusiveness. However, intrusiveness is a subjective concept and is difficult to be measured objectively. In this paper, by considering the fact that gentle advertising will not disturb audiences' attention(More)
In this paper, we propose an attention based method to provide convenient browsing experience on mobile devices. To achieve this, we extract video summary in both temporal and spatial domains. Firstly, an improved video attention analysis method is performed to obtain attention distribution of video. Then, temporal summarization is carried out by extracting(More)
Different extensions to a standard BPON (Broadband Passive Optical Network) are reported. The optical splitting factor was increased from 1:32 to 1:256. A dynamic MAC (Medium Access Control) protocol was demonstrated, which is QoS (Quality of Service) aware and improves the bandwidth efficiency of packet based services on a BPON. Another enhancement is to(More)
