H.264/SVC has been widely adopted to smart CE devices for network-adaptive video transmission. However, current H.264/SVC does not support sufficiently high subjective QoS (Quality of Service) because its scalability methods provide only coarse-grained network adaptivity. To address this problem, we propose Scalable ROI (SROI) algorithm that applies ROI (Region of Interests) concept to SVC (Scalable...
This paper explains the multi-channel based scalable video streaming system which guides evacuation way from the disaster of underground infrastructure. The method proposed by this paper has following merits. First, it can support various capability of user's mobile device by using H.264 SVC(Scalable Video Codec) technology. Second, it can transmit evacuation way by using available network channels...
HSDPA (high speed downlink packet access) is drawing great attention as the 3.5G technology capable of providing the wireless data service 3 ~ 4 times faster than WCDMA. Recently, HSDPA business has been expanding continuously from the perspective of network development and investment efficiency, in line with the global trend. As HSDPA looks set to account for about 16 percent of the entire number...
