Distributed video coding (DVC) is an emerging video coding paradigm due to its flexibility to introduce much lower encoding complexity than conventional predictive codecs, which is beneficial for some applications such as wireless video surveillance, wireless sensor networks, and disposable video cameras. Although DVC systems without feedback channel address a wider range of applications, it is not...
This paper proposes a new solution to improve the coding efficiency of depth map in 2D plus depth map of 3D video coding. The proposed algorithm is achieved to reduce coding time on using H.264 encoding for both color image and depth map and to enhance the encoding quality for 2D MV sharing to depth encoding. The method uses 3D perceptual attention regions to determine re-motion estimation MBs in...
Smooth rate control schemes are necessary for Internet streaming flows to use available bandwidth. To equally share the Internet bandwidth with existing Transmission Control Protocol (TCP) flows, these new schemes should meet TCP-equivalent criterion, i.e., achieve the same transmission rates as TCP under the same network conditions. However, when the available bandwidth oscillates, many of these...
Low-power wireless video sensor nodes play important roles for applications in machine-to-machine (M2M) network. Several design issues to optimize the power consumption of a video sensor node are addressed in this paper. For the video coding engine selection, the comparison between conventional video coding system and distributed video coding (DVC) system shows that although the rate-distortion performance...
In multicore environment, multithreading is often used to improve application performance. However, there are some unexpected anomalies which degrade the performance of multithreading applications. Some of the unexpected anomalies come from inappropriate thread dispatching by operating system. To solve this problem, a novel User Dispatching Mechanism (UDispatch) was proposed. Through modification...
This paper proposes a concept to construct a Traffic-Localized and Resource-Efficient tree-based architecture to support the delivery of an SVC-encoded live video streaming onto a Public-Shared Network. A Public-Shared Network consists of a large number of bandwidth sharable devices, such as sharable APs in a FON network. The SVC-encoded video streaming is employed to provide the smooth access of...
The mobile WiMAX systems based on IEEE 802.16e-2005 provide high data rate for the mobile wireless network. However, the link quality is frequently unstable owing to the long-distance and air interference and therefore impacts real-time applications. Thus, a bandwidth allocation algorithm is required to be modulation-aware, while further satisfying the latency guarantee, service differentiation and...
