PERFORMANCE ANALYSIS OF REAL TIME STREAMING PROTOCOL (RTSP) AND REAL TIME TRANSPORT PROTOCOL (RTP) USING VLC APPLICATION ON LIVE VIDEO STREAMING

Video is a means of delivering very complete information and can be implemented using streaming technology. Networking services for local media exchange are helpful in teaching and learning activities, such as simultaneous video playback. Submission of information in the form of this video can be done by unicast, multicast or Broadcast packet delivery Live video streaming using RTP and RTSP protocol. The test was done through three experiments ie unicast, multicast and broadcast for five times. The output occurring at (RTP) is 4.73 MBit / sec for 5 client, higher than from (RTSP) of 13.799 MBit / sec for 5 client. This test occurs a very high Delay on RTP while RTSP has a low Delay in RTP. Meanwhile, the packet loss that occurs in (RTP) is 124.50% lower than (RTSP) which is 6.06% from 5 clients each. Because RTSP is an applicationlevel protocol for data delivery control that has real time characteristics such as streaming media. While RTP is designed not for streaming but to handle the actual data transmission of data in the form of sound or image or both, especially those based on real time such as streaming media

Improving collaboration in augmented video conference using mutually shared gaze

To improve remote collaboration in video conferencing systems, researchers have been investigating augmenting visual cues onto a shared live video stream. In such systems, a person wearing a head-mounted display (HMD) and camera can share her view of the surrounding real-world with a remote collaborator to receive assistance on a real-world task. While this concept of augmented video conferencing (AVC) has been actively investigated, there has been little research on how sharing gaze cues might affect the collaboration in video conferencing. This paper investigates how sharing gaze in both directions between a local worker and remote helper in an AVC system affects the collaboration and communication. Using a prototype AVC system that shares the eye gaze of both users, we conducted a user study that compares four conditions with different combinations of eye gaze sharing between the two users. The results showed that sharing each other's gaze significantly improved collaboration and communication
