۱۰۶۳ نتیجهUsing the Draft H.26l Video Coding Standard for Mobile Applications
The mai n goals of the new ITU -T H.26L standardization effort are enhanced compression performance and provision of a “network-friendly” packet -based video representation addressing “conversational” (i.e., video telephony) and “non conversational” (i.e., storage, broadcast, or
Fully Scalable Video Coding with Packed Stream
Scalable video coding is a technique which allows a compressed video stream to be decoded in several different ways. This ability allows a user to adaptively recover a specific version of a video depending on its own requirements. Video sequences have temporal, spatial and qualit
Switched Error Concealment and Robust Coding Decisions in Scalable Video Coding
This work introduces two complementary techniques to improve the packet loss resilience of scalable video coding systems. First, a “switch per-pixel” error concealment (SPEC) scheme is proposed, which allows the decoder to exploit information from both the current base layer and
An Overview of Emerging Technologies for High Efficiency 3D Video Coding
3D video coding is one of the most popular research area in multimedia. This paper reviews the recent progress of the coding technologies for multiview video (MVV) and free view-point video (FVV) which is represented by MVV and depth maps. We first discuss the traditional multivi
ECC Video: An Active Second Error Control Approach for Error Resilience in Video Coding
To support video communication over mobile environments has been one of the objectives of many engineers of telecommunication networks and it has become a basic requirement of a third generation of mobile communication systems. This dissertation explores the possibility of optimi
A framework for efficient progressive fine granularity scalable video coding
In this paper, a basic framework for efficient scalable video coding, namely progressive fine granularity scalable (PFGS) video coding is proposed. Similar to the fine granularity scalable (FGS) video coding in MPEG-4, the PFGS framework has all the features of FGS, such as fine
Efficient Block Size Selection in H.264 Video Coding Standard
This letter aims at selecting an efficient variable block size mode in H.264 video coding standard for better compression performance. The proposed scheme is based on 3D Recursive Search algorithm and takes into account the motion vector cost and previous frame information. The b
Recent Advances in Peer - to - Peer Video Streaming by Using Scalable Video Coding
Scalable Video Coding provides important functionalities, such as the spatial, temporal, and SNR (quality) scalability, thereby significantly improving coding efficiency over prior standards such as the H.264/AVC and enabling the power adaptation. In turn, these functionalities l
Robust and efficient scalable video coding with leaky prediction
This paper presents a robust scalable video coding scheme with leaky prediction, suitable for time-varying error-prone channels, such as the Internet or wireless channels. The proposed scheme shows how leaky prediction can be utilized for efficient motion-compensated video coding
Real-time video streaming using H.264 scalable video coding (SVC) in multihomed mobile networks: a testbed approach
