1 Lab Seminar Video Presence System with One VS Multi Supported
Netmedia Lab 4/30/2019 Lab Seminar Video Presence System with One VS Multi Supported Jitae Bae 20, February, 2010 Hello everyone! This talk is about High-quality distributed visualization system This work is related to KISTI project for this year and my master thesis GIST Netmedia Lab., Gwangju , S. Korea

2 Contents Introduction & Background Related Work Motivation
Netmedia Lab Contents 4/30/2019 Introduction & Background Related Work Motivation Proposed Approach Conclusion Schedule For this presentation, I will introduce the concept of high-quality visualization, related work, the challenges for high-quality visualization And proposed system. Finally the remaining work GIST Netmedia Lab., Gwangju , S. Korea

3 Introduction & Background
Video Presence(VP) System Concept of presence Psychological sense of "being there" in environment based on technologically founded immersive base Three types of presence Personal presence The extent to which a person feels part of the environment Social presence The extent to which others (human and non- human ) exist in the environment Environmental presence The extent to which the environment acknowledges and interacts with the participants

4 Introduction & Background(cont)
Prototype VP system Video Presence Provide sense of presence by sharing multiple high-quality media Objective Develop a system and software for video presence

5 Related Work Cisco Telepresence Others
In-person experiences between individuals, businesses, and events. People everywhere can work, live, play, and learn together, in person over the network. Others HP “hallo”, Polycom “RPX”, Tandberg “Experia”

6 Motivation Many users want to present reality World issue and market
Immersive Collaboration Meeting Supporting reality meeting environment Using concept of presence World issue and market Many companys concentrate on this field Market is a wide scope.

7 Proposed Approch Understand library in VLC
Using by library : libraw1394, libiec 61883, mpeg2 dec, dvgrap libraw 1394 – Ieee 1394 network acquisition in Linux Libiec – Channel selection about multiple input stream Mpeg2 dec – mpeg2 transmission in vlc Dvgrap – HDV Image capture and play in vlc

8 Conclusion Success chapter 1 : VP system Problem Future work
Two Jvc camera transmission in Tiled display Similar multi view system(parallel) Using by VLC and SVC software Problem Frame rate very low (CPU limit) A little delay existence but there is no large difference Future work Overcome low frame rate A cause analysis about frame rate Examine Two machine or more… Eliminate delays Study vlc system and mpeg2 transmission system Source coding analysis of VLC Find synchronization method

9 Schedule 1 2 3 4 5 6 7 MPEG2 Transmission System seminar
System analysis Low frame rate analysis Image difference VP system (Three camera) VLC system And source coding accomplishment (1/31) (2/28) (2/28) (2/11) (4/30) (7/31)
