ABSTRACT
In this paper, we introduce a new scanning method for H.264 based Fine Granular Scalable video coding, which can significantly improve the subjective picture quality of a decoded scalable video. Since the network condition is fluctuated, it is often happened that the important part of the streaming data, especially video sequences, cannot be transmitted, and thus a viewer watches less interesting parts of the sequences or poorer quality of pictures in important regions. Therefore, this paper presents a new scanning method, called water ring scan method, for improving the subjective picture quality of the decoded scalable video by encoding and transmitting the visually important region most-preferentially as a watering is expanded in the lake from the location where gravel falls. The water ring scan method presented in this paper is to encode and decode video sequences at the location designated by a user. From the simulation results, it has been found that the proposed scan method can achieve significantly improved picture quality, especially on the region of interest as being compared with the traditional FGS scheme.

Improved lossless intra coding for H.264/MPEG-4 AVC
A new lossless intra coding method based on sample-by-sample differential pulse code modulation (DPCM) is presented as an enhancement of the H.264/MPEG-4 AVC standard. The H.264/AVC design includes a multidirectional spatial prediction method to reduce ...
On Lagrange multiplier and quantizer adjustment for H.264 frame-layer video rate control
H.264/AVC encoder employs a complex mode-decision technique based on rate-distortion optimization. It calculates rate-distortion cost (RDcost) for all possible modes to choose the best one having the minimum RDcost. This paper presents a frame-layer ...
Fast mode decision algorithm for intraprediction in H.264/AVC video coding
The H.264/AVC video coding standard aims to enable significantly improved compression performance compared to all existing video coding standards. In order to achieve this, a robust rate-distortion optimization (RDO) technique is employed to select the ...
