bstract. An encoded video bitstream is composed of two main omponents: the coefficient bits representing the discrete cosine ransform coefficients, and the header bits representing the header nformation (e.g., motion vectors, prediction modes, etc.). Compared ith previous video standards, the H.264 Advanced Video Coding AVC) standard has some unique features: (1) the header bits take p a consid...

In this paper we introduce an cooperative header compression scheme for 4G wireless networks. The main focus is to achieve robustness and low complexity for the compression. Furthermore the header compression scheme should work without any feedback information.

This document specifies a RObust Header Compression (ROHC) profile for compression of TCP/IP packets. The profile, called ROHC-TCP, provides efficient and robust compression of TCP headers, including frequently used TCP options such as selective acknowledgments (SACKs) and Timestamps. ROHC-TCP works well when used over links with significant error rates and long round-trip times. For many bandw...

C compilers in production environments often have to reprocess the same header les. CCC is a caching C compiler which maintains a database of partially processed header les so that repetitive work may be eliminated.

This document defines a ROHC (Robust Header Compression) profile for compression of IP/UDP/RTP (Internet Protocol/User Datagram Protocol/Real-Time Transport Protocol) packets, utilizing functionality provided by the lower layers to increase compression efficiency by completely eliminating the header for most packets during optimal operation. The profile is built as an extension to the ROHC RTP ...

Driving Decision-making Mechanism (DDM) is identified as the key technology to ensure the driving safety of autonomous vehicle, which is mainly influenced by vehicle states and road conditions. However, previous studies have seldom considered road conditions and their coupled effects on driving decisions. Therefore, road conditions are introduced into DDM in this paper, and are based on a Suppo...

Email becomes the major source of communication these days. Most humans on the earth use email for their personal or professional use. Email is an effective, faster and cheaper way of communication. The importance and usage for the email is growing day by day. It provides a way to easily transfer information globally with the help of internet. Due to it the email spamming is increasing day by d...

There have been many important developments in road building equipment in recent years; possibly the greatest progress has been made with earth-moving equipment. The size and mobility of earthmoving equipment have been developed to such an extent that pro­ duction has been increased tremendously on the average road con­ struction project. This has had a definite effect on the cost of road work ...

ρ-domain rate control has been shown to be a simple yet effective rate control approach for DCT-based hybrid video codecs. When it is applied to H.264/AVC, improvements need to be made because of the large amount of header information and the QP-dependent Rate Distortion Optimization (RDO). In this paper, we propose a novel rate model to estimate the size of header information accurately. We pr...

In this paper we consider the usage of multiple base stations for IP streaming applications towards wireless terminals. The usage of multiple channels, coming from different base stations, increase the capacity and robustness at the price of an additional IP overhead. Therefore, we advocate to use a novel IP header compression scheme for efficient usage of spectrum resources. We propose the coo...
