A Performance Comparison of Single-Stream and Multi-Stream Approaches to Live Media Synchronization

This paper presents a performance comparison between the single-stream and the multi-stream approaches to lip synchronization of live media (voice and video). The former transmits a single transport stream of interleaved voice and video, while the latter treats the two media as separate transport streams. Each approach has an option not to exert the synchronization control at the destination, which leads to four basic schemes. On an interconnected ATM-wireless LAN, we implemented the four basic schemes with RTP/RTCP on top of UDP and two variants which exercise dynamic resolution control of JPEG video. Making the performance measurement of the six schemes, we compare them to identify and evaluate advantages and disadvantages of each approach. We then show that the performance difference between the two approaches is small and that the dynamic resolution control improves the synchronization quality.application/pdfjournal articl

3RD HARMONIC OPERATION OF SIT INVERTER RF SOURCE FOR ICRF HEATING IN THE DIVERTOR PLASMA SIMULATOR NAGDIS-II

The purpose of this paper is to study the 3rd harmonic operation of a voltage source inverter power supply. A Static Induction Transistor (SIT) inverter power supply is used in this experiment. This power supply can generate 14 kW in steady state operation and its upper limit frequency of the gate driver is 1.7 MHz. The advantage of the 3rd harmonic operation is that the RF power at higher frequency range beyond the switching limit can be generated. It should be also noted that the driver circuit needs no special modification for this operation. The conversion efficiency and maximum output power are investigated as a function of output frequency. The conversion efficiency with harmonic operation is a little lower than the conversion efficiency with fundamental operation. At the frequency of <3 MHz, the conversion efficiency is higher than that of conventional linear amplifiers when using this SIT inverter power supply.journal articl
