Salvador/Brazil and Daejeon/Korea. The full shot of the main stage at Chiang Mai
will be streamed to KISTI/Korea in real time.
Date: Monday, 13-Feb-2012
Time: 17:00 (Chiang Mai) | 11:00 (Barcelona) | 8:00 (Salvador) | 19:00 (Daejeon)
Venue: APAN 2012 Main auditorium (Same as the APAN 2012 Opening Plenary)

Performance Infrastructure
• As the performance includes live interaction of dancers and audience in the
four venues (endpoints) - Chiang Mai, Barcelona, Salvador and Daejeon - the
network infrastructure must support the video applications requirements for
live transmission of HD audio and video streams.
Monitoring
• All endpoints must have in their connections monitoring of their respective
network performance and monitoring of the multimedia applications.
Network Endpoints
• Barcelona : Konic Thtr / i2cat
• Chiang Mai : APAN main auditorium

Software : Arthron
ARTHRON was developed to assist the execution of artistic performances that make use of multimedia
representations and real time sharing of real and virtual spaces. In this context, Arthron was used in the
domain of research and development in Art and Technology, as well as in artistic presentations like
Versus (2005), (In)TOQue (2008) and e-Pormundos Afeto (2009-1011) events. ARTHRON’s main
functionality is the simple and direct interface, designed for the manipulation of different sources and
streams of media (audio and video) simultaneously. This way the user can remotely add, remove and
configure the presentation format as well as schedule the streams of media in time and space during an
event.
ARTHRON is composed of six main components: Articulator, Encoder, Decoder, Reflector,
VideoServer and MapManager. The Articulator is responsible for the remote management of the other
components, concentrating a great part of the ARTHRON functionalities such as stream scheduling
(manual or automatic, via the creations of different scenarios), network monitoring and measurement,
remote configuration of other modules, access control, automatic generation of a web page for online
publication of low definition videos, addition of several video effects, chat for communication between
the components and much more. The Encoder is responsible for the capture and encoding (when
necessary) of the media source, which can be external (DV or HDV camera, DVD, etc) or internal (a
local file). The Decoder’s main functionality is to decode and display the media stream in a specific
device (monitor, projector, etc). The Reflector is responsible for the replication and redistribution of a
media stream over the network. The VideoServer is able to transcode the media streams that will be
published online, being able to transcode to the flv, ogg and h264 formats. The MapManager controls
and displays the interactive map of the ARTHRON components. All streams can be generated in
geographically distributed locations.

In Figure B we can see a general overview of the objects in scene during the show. The dancer located inside the Dragão do
Mar Theater, in Fortaleza/Brazil, can be seen in (1). The central screen that receives the video stream of the dancer from
Barcelona/Spain can be seen in (3). On the left screen(2) is shown the video stream generated by the robot Galateia, from the
NatalNet laboratory. On the right screen (4) is the video sent to the internet and several people could watch online, inside the
GTMDA website. In (5) we can see the musician located in Fortaleza.

Cyber World, now the tools of the digital age give us to easily communicate with people on the other
side of the world in new ways. New contacts create a new culture, new arts create new paradigm.
Here, there are gestures from three locations meeting virtually and they are suddenly transferred to
another space. Three points disperse and flock dreamily. Harbor your futuristic dream in the wide
world while taking a cyberwalk with them.

Remote Control for Music
to synchronize audio and video from multi-sites
step 1 : measuring of RTT using OSC(Open Sound Control)
• sending a 'bang' signal from CM to Ba/Br
• The arrived 'bang' signal returns to CM immediately.
• measuring the RTT between started 'bang' and returned 'bang' at CM (fig.1)
※ It takes about 380ms like ping.
fig.1 RTT measuring

16. DQ12 Dancing across Oceans Feb 13th 2012 @ ECC, Thailand, e-Culture WG, 33th APAN meeting 16
step 2 : measuring of delay time including latency through ARTHRON from each site Ba/Br to CM
• shooting the Max6 window with a camera connected to ARTHRON at Ba/Br (fig.2)
• sending a 'bang' signal from CM to Ba/Br, at the same time, started the video recording with a webcam
connected to Max6 machine at CM (fig.3)
• When a 'bang' signal arrived at Ba/Br, the object in the Max6 window will blink in red.
• The video recording at CM will continue until the red blinking on the video from Ba/Br is appeares
• calculating video frames from the start to red blinking, and then multiply 33(FPS: 30)
• The actual delay time is {video delay time - (OSC RTT/2)}
※ I predict it will take around 1~2s according to codec.

step 3 : remote control of starting point of music at Ba/Br
• adjusting the delay time of each start signal sent to Ba/Br and of start signal for the
local music which should be synchronized with receiving video from Ba and Br
• Finally, we can get synchronized audio and video all together between three sites.

The idea of synchronizing the synthesized video
data with the prepared local sound at Chiang Mai
will be able to provide more reliable quality of
music. Also, 3D-speaker system can be employed
on the procedure if it needs.
