Hangout

The power of HangoutHangout 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;

  • Borowsers
    • Google Chrome 10+
    • Internet Explorer 8+
    • Mozilla Firefox 3+
    • Safari 4+
  • Operating Systems

    • Ubuntu and other Debian based Linux distributions
  • Processor Minimum Requirements
    • Any 2 Ghz dual core processor or greater.
  • Bandwith
    • For 1:1 connections we suggest a 1 mbps/1 mbps (up/down)
    • For group video connectivity we suggest 1 mbps/2 mbps (up/down)

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:

  • Maximum 10 participants.
  • There's a 150 minute check-in to make sure you're still there.

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.

Conferencing

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.

VOIP

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.

 

Telepresence

Components of video conferencing

The components required for a videoconferencing system include:

  • Video input : video camera or webcam
  • Video output: computer monitor, television or projector
  • Audio input: microphones, CD/DVD player, cassette player, or any other source of PreAmp audio outlet.
  • Audio output: usually loudspeakers associated with the display device or telephone
  • Data transfer: analog or digital telephone network, LAN or Internet or a satellite-based system, a broadcast signal or other communications technology
  • Personal computers
  • A main computer control system; a data processing unit that ties together the other components, does the compressing and decompressing, and initiates and maintains the data linkage via the network.

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.

 

VoIP

Voice over IPVoice over IP (VoIP, abbreviation of voice over Internet Protocol) commonly refers to the communication protocols, technologies, methodologies, and transmission techniques involved in the delivery of voice communications and multimedia sessions over Internet Protocol (IP) networks, such as the Internet.

The steps involved in originating a VoIP telephone call are signaling and media channel setup, digitization of the analog voice signal, encoding, packetization, and transmission as Internet Protocol (IP) packets over a packet-switched network. On the receiving side, similar steps in the reverse order, such as reception of the IP packets, decoding of the packets and digital-to-analog conversion reproduce the original voice stream. Early providers of voice over IP services offered business models (and technical solutions) that mirrored the architecture of the legacy telephone network.

Second generation providers, such as Skype have built closed networks for private user bases, offering the benefit of free calls and convenience, while denying their users the ability to call out to other networks.

Third generation providers, such as Google Talk have adopted the concept of Federated VoIP – which is a complete departure from the architecture of the legacy networks. These solutions typically allow arbitrary and dynamic interconnection between any two domains on the Internet whenever a user wishes to place a call.

A major development that started in 2004 was the introduction of mass-market VoIP services that utilize existing broadband Internet access, by which subscribers place and receive telephone calls in much the same manner as they would via the public switched telephone network (PSTN)

A VoIP phone is necessary to connect to a VoIP service provider. This can be implemented in several ways:
  • Dedicated VoIP phones connect directly to the IP network using technologies such as wired Ethernet or wireless Wi-Fi. They are typically designed in the style of traditional digital business telephones.
  • An analog telephone adapter is a device that connects to the network and implements the electronics and firmware to operate a conventional analog telephone attached through a modular phone jack. Some residential Internet gateways and cablemodems have this function built in.
  • A softphone is application software installed on a networked computer that is equipped with a microphone and speaker, or headset. The application typically presents a dial pad and display field to the user to operate the application by mouse clicks or keyboard input.
Features of Mobile

Multipoint video conferencing

Multipoint videoconferencing allows three or more participants to sit in a virtualconference room and communicate as if they were sitting right next to each other. Until the mid 90s, the hardware costs made videoconferencing prohibitively expensive for most organizations, but that situation is changing rapidly. Many analysts believe that videoconferencing will be one of the fastest-growing segments of the computer industry in the latter half of the decade.

Before you can use multi-point video conferencing, it's first important that you have an understanding of how the technology involved works. Basically, multi-point video conferencing uses a series of cameras, at least one in each location of the conference, and transmits the audio and video that is picked up over a computer network where it is received by the other members of the conference. This works similar to a telephone conference call, allowing all members to interact in real time, but instead of simply being a telephone call the members can see what is going on at the other locations and often can pull up additional information from their computer and display it as a part of the conference as well.

Telepresence System:

A telepresence system is a high-end videoconferencing system and service usually employed by enterprise-levelcorporate offices.

Telepresence conference rooms use state-of-the art room designs, video cameras, displays, sound-systems and processors, coupled with high-to-very-high capacity bandwidth transmissions. Typical use of the various technologies described above include calling or conferencing on a one-on-one, one-to-many or many-to-many basis for personal, business, educational, deaf Video Relay Service and tele-medical, diagnostic and rehabilitative use or services.

New services utilizing videocalling and videoconferencing, such as teachers and psychologists conducting online sessions, personal videocalls to inmates incarcerated in penitentiaries, and videoconferencing to resolve airline engineering issues at maintenance facilities, are being created or evolving on an on-going basis.

Telepresence requires that the users' senses be provided with such stimuli as to give the feeling of being in that other location. Additionally, users may be given the ability to affect the remote location. In this case, the user's position, movements, actions, voice, etc. may be sensed, transmitted and duplicated in the remote location to bring about this effect. Therefore information may be traveling in both directions between the user and the remote location.

Telepresence via video deploys greater technical sophistication and improved fidelity of both sight and sound than in traditional videoconferencing. Technical advancements in mobile collaboration have also extended the capabilities of videoconferencing beyond the boardroom for use with hand-held mobile devices, enabling collaboration independent of location.

The first commercially successful telepresence company, Teleport (which was later renamed TeleSuite), was founded in 1993 by David Allen and Harold Williams. Before TeleSuite, they ran a resort business from which the original concept emerged, because they often found businesspeople would have to cut their stays short to participate in important meetings. Their idea was to develop a technology that would allow businesspeople to attend their meetings without leaving the resorts so that they could lengthen their hotel stays.
