Hangout is face to face to face video chat offered free by Google. Hangout may also be used for virtual meetings to increase team’s productivity with powerful tools like screen sharing and Google Docs. One can broadcast conversation or a concert or lecture via hangout to the world.
In addition, while only 10 people can participate in a Hangout, an unlimited number of people can watch one. Hangouts can also be used for free on any Android device.
At most 10 small frames which are representing the all attendees. No policing of who gets to speak when — the software recognizes the voice of who’s speaking and pops their face into the main picture frame until someone else starts talking. Much more better and less onerousness than having a moderator.
Since June, 2011 Mashable tech team using hangouts their internal meetings. And PayDeg is using hangout to support its trainings.
Team collaboration gets better when you’re face to face. Hangouts offers a suite of productivity apps that let you share what’s on your screen, collaborate in Google Docs, view presentations or diagram together and watch some videos from Youtube. To access these, simply click the “Add app” button inside your hangout to browse and add new apps. If a team member can’t join the hangout, you can also dial the person in by clicking on the “Invite” button and then the “+telephone” link. Don't forget doing that you may be getting phone bills or for some countries it may not work.
Requirements for Hangout;
Camera and audio are also needed to have a good communication, but they are not must technically since there is also a chat board in the hangout window.
Specs and limits of Hangouts
There are a few specifications and limitations of Hangouts that you should be aware of:
Getting started with Hangouts..If you meet the system requirements then you need to download the hangout plugging from; Plugging. after that make sure you have the latest drivers for your webcam. You need to take care of light too. Headphones with a built in microphone will dramatically improve your Hangout experience.
Hangout on Air
One can share and record own live discussions and performances with everyone!
With Hangouts on Air one can stream own hangout publicly on own Google+ profile, own YouTube channel, and own ebsite. There is no need special software to record the conversation. Every Hangout On Air is automatically saved to own YouTube account.
Here is the Gif above just prepapared by PayDeg you may get an idea how to Hangout OnAir -Broadcast at Google Plus.
When the hangout is over, hangout video is shared publicly on Google+ and on YouTube channel. There is a possibility to reshare the video just like any other.
With Hangout on Air it is possible to broadcast afterinviting people or circles(I will explain about it on the video I will provide) from Google Plus. A live player of the hangout will be posted to host's Google+ Home page and YouTube channel.
Hangout on Air is possible in many ways;
While using Hangout On Air before starting the broadcast, you’ll be asked to review the terms of service. All content, including any music or videos played in the background of the hangout, should be avoided unless explicitly owned by you. Copyright issues must be considered while doing Hangout on air.
This also applies to anyone joining your broadcasted hangout - if others play music, videos, or other content that they do not own, ask them to stop and/or leave the hangout immediately.
What is conferencing?
Conferencing is defined as "the joining together of more than two telephone users in a single call. Typically a call will be established between two persons, one will then hold the call, call a third party and then press a button to join all three parties in one call."
What is video conferencing?:
Video conferencing is a communications technology that integrates video and audio to connect users anywhere in the world as if they were in the same room. A video conference (also known as a video teleconference) allows people at two or more locations to communicate via live, simultaneous two-way video and audio transmissions.
When using video conferencing, participants can see and hear each other in real time or close to it, allowing natural face-to-face conversations and visual elements that are not possible with voice-only communications technology.
What Are the Different Types of Video Conferencing Technology?:
There are two different types of video conferencing and many different companies that manufacture and sell the equipment.
Point-to-point video conferencing is communicating in real time with any number of people who are in two different physical locations. A point-to-point (two-person) video conferencing system works much like a video telephone. Each participant has a video camera, microphone, and speakers mounted on his or her computer. As the two participants speak to one another, their voices are carried over the network and delivered to the other's speakers, and whatever images appear in front of the video camera appear in a window on the other participant's monitor.
Agood free example for point-to-point video conferencing is Skype.The service allows users to communicate with peers by voice using a microphone, video by using a webcam, and instant messaging over the Internet.
Multi-point video conferencing is communicating in real time with any number of people in three or more geographic locations. When numerous individuals are using video conferencing technology to all communicate together, then each one likely needs a microphone and may need a camera or webcam as well.
There is also a great deal of other video conferencing technology used in such conferences, including other pieces of hardware. Each person viewing or participating in this type of conference usually requires a computer and a display monitor. Input devices such as a mouse and keyboard are typically needed as well, though some systems may use more specialized input equipment. All of this video conferencing technology is typically connected to a network to allow the user to connect to other users and receive data sent by the host.
History of Video Conferencing:
First systems developed by AT&T Corporation in the 1950s, failed due to the poor picture quality and the lack of efficient video compression techniques. The greater 1 MHz bandwidthand 6 Mbit/s bit rate of the Picturephone in the 1970s also did not achieve commercial success, mostly due to its high cost, but also due to a lack of network effect —with only a few hundred Picturephones in the world, users had extremely few contacts they could actually call to, and interoperability with other videophone systems did not exist.
It was only in the 1980s that digital telephony transmission networks became possible, such as with ISDNnetworks, assuring a minimum bit rate (usually 128 kilobits/s, we had 56kilobits/s at that time in Turkey over phone lines) for compressed video and audio transmission. Many of the technologies, such as the Media space, are not as widely used today as video conferencing but were still an important area of research. The first dedicated systems started to appear in the market as ISDN networks were expanding throughout the world. One of the first commercial video conferencing systems sold to companies came from PictureTel Corp., which had an Initial Public Offering in November, 1984. In 1984 Concept Communication in the United States replaced the then-100 pound, US$100,000 computers necessary for teleconferencing with a $12,000 circuit board which doubled the video frame rate from to 30 frames per second, and which was reduced the equipment in size to a circuit board that fit into standard personal computers. The company also secured a patent for a codec for full-motion videoconferencing, first demonstrated at AT&T Bell Labs in 1986.
Finally, in the 1990s, IP (Internet Protocol) based video conferencing became possible, and more efficient video compression technologies were developed, permitting desktop, or personal computer (PC)-based video conferencing. In 1992 CU-SeeMe was developed at Cornell by Tim Dorcey et al. In 1995 the first public videoconference between North America and Africa took place, linking a technofair in San Francisco with a techno-rave and cyberdeli in Cape Town. At the Winter Olympics opening ceremony in Nagano, Japan, Seiji Ozawa conducted the Ode to Joy from Beethoven's Ninth Symphony simultaneously across five continents in near-real time.
In the 2000s, videotelephony was popularized via free Internet services such as Skype and iChat, web plugins and on-line telecommunication programs which promoted low cost, albeit low-quality, video conferencing to virtually every location with an Internet connection.
Technological developments in the 2010s by video conferencing developers have extended the capabilities of video conferencing systems beyond the boardroom for use with hand-held mobile devices that combine the use of video, audio and on-screen drawing capabilities broadcasting in real-time over secure networks, independent of location.
Mobile collaboration systems now allow multiple people in previously unreachable locations, such as workers on an off-shore oil rig, the ability to view and discuss issues with colleagues thousands of miles away. Traditional videoconferencing system manufacturers have begun providing mobile applications as well, such as those that allow for live and still image streaming.
Components of video conferencing
The components required for a videoconferencing system include:
The components within a Conferencing System can be divided up into several different layers: User Interface, Conference Control, Control or Signal Plane, and Media Plane.
