Thus, it is will resulting in packet lost the frame with audio together.…”

Remote screen recording is a system that records whole actions on a remote computer screen, and displays the actions on a client computer screen at the same time. Traditionally, screen recording are streamed in a video format, which large data usually results in high CPU utilization and heavy network loading. Therefore, in order to reduce CPU utilization and network bandwidth loading, the screen recording system records and only sends the blocks which have updates on the recording screen. A screen update on any part of the recording screen is called a "changed block" in this paper. Only recording and sending the changed blocks definitely reduces the network bandwidth and CPU loading. Because of only sending changed blocks, this study comes up with a media synchronization problem between a video stream and remote screen data stream in a distance learning system due to an unstable network environment. This study proposes a fast skip mechanism, called Fast Media Synchronization (FMS), to match the video stream playback by adjusting the remote screen data stream. The FMS quickly determines whether the changed blocks overlap. In the fast skip mechanism of FMS, overlapping areas among changed blocks in a screen data stream will be effectively deleted. In this paper, four different scenarios web browsing, document editing, slide presentation, and video playback, are designed to test the effectiveness of applying FMS. The experiment results shows that the FMS mechanism approximately reduces 85% of processing time, 57% to 99% of the frequency of pasting times, 70% to 90% the number of comparisons, and 70% to 90% the total pasting area. Furthermore, the proposed FMS mechanism can also be applied to improve the efficiency of different screen recording systems, such as remote desktop, distance conferencing, and video streaming, etc.

“…We note that synchronization of audio (voice) and video streams is a well-attended problem in the literature [1]- [4]. However, conventional synchronization control schemes typically rely on the use of the timestamp information on the audio/video streams for inter-stream synchronization, including adaptive buffer control and playout scheduling.…”

As IP telephony gains more popularity, interworking with conventional PSTN telephony has also gained more importance. In particular, an increasing number of new telephony services now involves both packet-switched (IP telephony) and circuit-switched (PSTN telephony) voice legs in one call session. One common problem that arises for enabling such new services is the need for synchronization of voice streams that traverse through heterogeneous telephony systems. In this paper, we first identify the key role of voice synchronization across heterogeneous telephony systems for services such as seamless handover between WLAN and cellular networks and multi-party audio conferencing with video overlay. We then explain the challenges in synchronizing circuit-switched and packet-switched voice streams, including codec distortion, packet losses, line noises, and overlapping utterances. To achieve voice synchronization, we proceed to investigate three different approaches based on digital speech processing techniques in the waveform, cepstrum, and spectrum domains. Finally, we compare the performance benefits and tradeoffs of different approaches, thus motivating further research along this direction.

Abstract-This paper covers review of a value added service and surveillance for a wide range of applications such as Air craft System, Road traffic signal offenders, Monitoring ship movements etc. The operation is carried out in three stages such as sensing, processing and transmitting / receiving the data. Here sensors play a major role in measurement of physical quantities such as temperature, pressure, speed etc., which can be read by an observer or by an instrument and transmit during abnormalities. Recorder is used to provide audio & video information which can be transmitted to the relevant authorities using wireless networks.Index Terms-Sensors, intelligent data recorder, black fin processor, transmitter, receiver and wireless n/w.
