A Rate Control Scheme for H.264 Video Under Low Bandwidth Channel

Tags:
bandwidth issues

Overview The dilemma of the Quantization Parameter (QP) being involved in both rate control and Rate-Distortion Optimization (RDO) prevents using the traditional rate control scheme. Although some rate control schemes are proposed to circumvent the dilemma, the inaccurate prediction model and improper bit allocation deter H.264 application on low bandwidth channel. To resolve this issue, this paper proposes a novel rate control scheme by considering the MacroBlock (MB) encoding complexity variation and buffer variation and by exploiting the spatio-temporal correlation sufficiently well.

Warnings "ignored" as gov't IT project cost doubles

The RPA said this was the result of the growing complexity of the payments scheme, the high volume of applications for funds and the fact that some of the schemes were abolished after Accenture had started work on the systems to support them.

Live Webcast: Telecoms 2.0 - Where is telecoms heading?

In this webcast, our panel of experts will review where we are with next generation telecoms in the UK, working through the concept of 'Telecoms 2.0': - Realising the potential of Next Generation Networks - why it isn't just about the technology? - What attributes should firms be looking for in their telco partner? - Is the relationship between telco provider and customer changing? - What things need to happen to make next generation services a reality? - You say you want the supplier to change. Do you want to change too? - What is Telecoms 2.0?

Telecom 2.0: Mind over matter

ntl:Telewest Business believes that the role of the telco is evolving. Gone are the days when it was enough to simply focus on circuits and minutes, customers now need a far higher degree of interaction and look for suppliers who will talk business solutions with them.
