! 빅블루버튼 (BigBlueButton)
빅블루버튼 (BigBlueButton, BBB) 는 오픈소스의 실시간 협업 도구입니다. (음성 / 화상 / 화면공유 / 채팅 / 화이트보드 / 녹음) 등 이 여러 개의 오픈 소스 컴포넌트 상에서 제작되었으며 원격 교육에 촛점을 두고 있습니다. 사용자는 브라우저에 플래시플레이어 플러그인만 필요합니다.

!! 소개
티키와 빅블루버튼의 통합의 주요 기능들
* 티키 사용자 시스템을 이용하여 1-클릭 로그인으로 빅블루버튼에 로그인 가능
* 티키의 권한과 그룹 시스템을 통한 빅블루버튼 세션 상에서의 다양한 권한기능
* 티키 내부에서 빅블루버튼 녹화 내역을 나열
((Tiki5|Tiki 5.0)) 에서는 BBB 0.64 를 지원하였고, Tiki 5.1 (그리고 이후) 버전에서는 BBB .64 과 .7 을 둘 다 지원하였습니다
((Tiki8|Tiki 8.0)) 에서는 녹화와 재생과 같은 빅블루버튼 0.8 의 새 기능 지원이 추가되었습니다 (그리고 BBB 의 이전 버전이 계속해서 지원되었습니다).
((Tiki9|Tiki 9.0)) 에서는 미팅에 참여할 권한이 ㅇ벗는 사용자들에게 녹화내용을 보여주는 것을 허용하는 새로운 권한 ( tiki_p_bigbluebutton_view_rec ) 이 추가되었습니다
((Tiki10|Tiki 10.0)) 의 관리자들은 이제 녹화내용을 삭제할 수 있습니다.
빅블루버튼 사용자들은 플래시가 있어야 합니다. 서버에 대하여, 2기가바이트의 물리적 RAM을 가진 전용 서버가 필요합니다 (이는 호스트에서 가상 머신의 스와핑을 통한 것이 아닙니다). 빅블루버튼은 티키처럼 LGPL 으로 라이센스 됩니다.

!! BBB 사용법
빅블루버튼을 사용하려면 웹브라우저에 플래시플레이어를 위한 플러그인이 올바르게 설치되어있어야 합니다.
이는 특정 운영체제와 브라우저의 조합에서는 약간 복잡할 수도 있습니다. 예를 들면, BBB에 연결을 처음 시도할 때 플래시 플러그인이 예기치 않게 크래시된 적이 있다면 (예를 들면, GNU/Linux 기반의 64비트 운쳥체제이고 플래시플러그인을 시스템 리포지터리에서 설치를 했을 경우), 다음의 단계를 밟아서 플래시플러그인 설정을 수정하는 것을 시도할 수 있습니다:
* 모질라 파이어폭스를 브라우저로 사용하고 다음 익스텐션을 설치: __Flash-Aid__:
** https://addons.mozilla.org/en-us/firefox/addon/flash-aid/
* 익스텐션에 의하여 생성된 새 아이콘의 설치를 선택하고 "__Quick Mode > Install beta flash__" 을 선택
** 이는 설치과정을 통한 안내를 제공합니다. 설치 마지막에 요청된 대로 파이어폭스를 재시작.
* BBB 설치로 돌아가서 다시 연결 시도.
부가적으로 웹캠이나 마이크를 사용하려할 때 윈도우를 클릭하여 원격서버에서 받아들이도록 할 수 없다면, 다음 방법을 통하여 수동으로 활성화할 수 있습니다:
* 브라우저로 아래의 URL을 방문
** http://www.macromedia.com/support/documentation/en/flashplayer/help/settings_manager06.html
* accept the connection from the server of your interest so that it doesn't ask you each time you try to connect to that bbb installation.
!! How to use BBB in Tiki
!!!# Enable the feature and plugin
Enable the feature at "__Admin home > Community > BigBlueButton__" tab.
Enable the plugin at "__Admin home > Editting and plugins > Plugins > BigBlueButton plugin__"
!!!# Place the bbb plugin call in a wiki page
Select the BigBlueButton plugin from the plugin helper popup box thorugh the edit box in the wiki page:
{CODE(wrap="1", ln="1")}
{bigbluebutton name="77777" prefix="guest" welcome="Welcome to the BBB from our web site" logout="http://mywebsite.org/myexitpage" recording="0"}
{CODE}
If you want to record your meetings, change the param recording from 0 to 1.
Note:
* Ensure that you are not caching that wiki page (set cache for that wiki page to "0". Otherwise, anonymous users willing to join a meeting might experience some connection problems in some cases.
!!!# Connect to BBB
An anonymous user would see this in a wiki page when no one is connected to the metting yet:
{img src="display690" url="display690" width="400" rel="box[g]" imalign="center" desc="click to expand" align="center" styleimage="border"}
If there is anohter guest user connected (not logged in Tiki at the time of connection, thus loged in BBB as VIEWER), the page would look like:
{img src="display696" url="display696" width="400" rel="box[g]" imalign="center" desc="click to expand" align="center" styleimage="border"}
If a user logs in the page, new buttons will be seen for him, depending on his tiki permissions, but for sure the username will be taken from his tiki username, andpermissions will be transferred from Tiki to BBB.
If that user connects to the BBB channel, then he will be connecting as MODERATOR.

!! Videos about Tiki & BBB
The Tiki community ((tw:Dogfood))s BigBlueButton at [http://tiki.org/live|tiki.org/live].
::{youtube movie="Wjvt831vtUQ" allowFullScreen="y"}::
::{youtube movie="rJq2XwojLp8" allowFullScreen="y"}::
The Tiki community has been testing BigBlueButton for this type of live collaboration and members of the community have decided to enter in a long-term integration partnership to maintain it as a Tiki feature, starting in ((Tiki5)).
!! About the integration
Similar to ((Kaltura)), BigBlueButton needs to be installed alongside Tiki (can be on a different physical server). Each project remains standalone, and we'll collaborate to continuously improve the glueware between the two.
At first, Single Sign On, but over time, we expect that many features will meld. The Tiki community will ((tw:DogFood)) extensively. ((Tiki8)) integrated the new record and playback features from BigBlueButton 0.8
!! Set-up
Before setting up the tiki integration, the BigBlueButton server stack must be installed. [http://code.google.com/p/bigbluebutton/wiki/Installation|Detailed instructions] are provided for multiple platforms. However, using the [http://code.google.com/p/bigbluebutton/wiki/BigBlueButtonVM|provided virtual machine] is the easiest way to go. Also note that there are [http://code.google.com/p/bigbluebutton/wiki/FAQ#What_are_the_bandwidth_requirements_for_running_a_BigBlueButton|heavy bandwidth requirements].
To enable the integration in tiki, you need the following information:
* The BigBlueButton server location.
* The [http://code.google.com/p/bigbluebutton/wiki/FAQ#Where_is_the_security_salt_located?|server salt -- a secret token used to generate call signatures. This value is located inside the bigbluebutton.properties file on the BigBlueButton server.]
** you can also have BBB report to you that server salt key with the command on the server:
++ {CODE(colors="bash")}
bbb-conf --salt
{CODE}
!! Creating rooms
The user interface for BigBlueButton goes through a wiki plugin. You can use it in wiki pages or most wiki-parsed text areas. To schedule meetings on a calendar, you can use the calendar feature.
{CODE(caption=Sample)}
{bigbluebutton name=My Meeting Room}
{CODE}
If the server location was configured successfully, the BigBlueButton logo will appear. A create button will be proposed to create the new room (a permission is required, but administrators have all permissions). If the salt was set-up correctly, you will be redirected to the meeting room.
Going back to the plugin, you can set-up the permissions to select who can join the meeting room or moderate it.
More info at ((PluginBigBlueButton))
!! Asterisk
To use the voip feature when using a room name instead of a number:
{CODE(caption="Change",wrap="0",ishtml="0",ln="0",wiki="0",rtl="0",cpy="0")}open the config:
sudo nano /etc/asterisk/bbb_extensions.conf
then replace:
exten => _XXXX.,1,Playback(conf-placeintoconf)
with:
exten => _.,1,Playback(conf-placeintoconf)
and replace:
exten = _XXXX.,n,Konference(${EXTEN},H)
with:
exten = _.,n,Konference(${EXTEN},H)
Than reboot the Big Blue Button server with bbb-conf --restart.
note: if you don't have nano installed use sudo apt-get install nano{CODE}
!! Uses
This will help with several related but slightly different uses.
!!! Webinars / e-learning
Scheduled, live, interactive, one to many delivery of knowledge. The session could be one time (webinar) or an ongoing course with a regular schedule. This is BigBlueButton's core objective "our focus is to make the best web conferencing system for distance education."
!!! Remote support
A visitor clicks a link on a brochure website and is put in contact with a representative of the organization. This is similar to Tiki's ((Live Support)) feature (ad hoc 1 on 1 chat help support), but with BigBlueButton's feature set, there are way more possibilities (screen sharing, co-browsing, etc.)
!!! Team meetings
Useful for ((tw:Teams)) to meet & coordinate. These are typically scheduled (for instance with ((PluginConvene)) since ((Tiki9)) and Tiki ((Calendar))) and have an agenda (presumably in a ((wiki)) page). Ideally, decisions are recorded (presumably in a ((wiki)) page). Everyone can be on audio & webcam. Headsets are recommended.
!!! Broadcasting live events
This will be useful during ((tw:TikiFests)). A projector can be setup at the live event so all participants can see everyone and follow the discussion on the chat. Typically, remote participants can listen in, but will respond in the text chat. (Just because of logistics and ambient noise).
* An alternative is http://www.ustream.tv/user/tikiwiki
* An example: ((tw:TikiFestBigBlueButton))
!!! Community chat
This is the place to go to hang out with "everyone". It's on 24/7 and can be idle for long whiles. It should be logged as a lot of knowledge, answers and links are shared there. Quick "decisions" are often taken there as well (ask a quick question and if ''everyone'' seems ok with it, it must be ok). Even if some users may be identified with special rights (ex.: ops), the room is very p2p. It's possible to break out of the room into a smaller one for a short, focused or private discussion. Historically, we use [http://irc.tiki.org|irc.tiki.org] but we could eventually develop an IRC to BigBlueButton gateway.
!!! Surveillance camera
Typically a video stream which can be monitored and recorded.
