The History and Current Application of Video Conferencing Solutions

Video conferencing solutions may be thought of as the whole gamut of technological and proceduralprocesses used to facilitate a video conference. A video conference is any conference, meeting or conversation that is facilitated by video and audio technology, and which allows persons not all physically present at the same location to confer with each other.

Video conferencing has been around in various forms since the invention of the television, which was initially demonstrated by sending an image through a solid (coaxial) cable to another room. In its modern form it was used by the Third Reich to communicate between post offices in major German cities.

Clearly the march of audio visual technology has been swift and constant: and the modern video conferencing solution bears little resemblance to the small crackly sets used in the 1930s. Modern video conferencing solutions may use large, high definition plasma or LCD screens and superb audio transmission software to create the impression that participants are actually in the room with their confederates. In the early part of the 21st century, video conferencing rooms were set up in which life size images of conference attendees were displayed on huge monitors arrayed down a boardroom table: the effect given was as though the other half of the room was "inside" a television screen.

Essentially, modern video conferencing solutions rely on a core software technology able to stream audio and video together in real time. The real time element is important in conferencing because delays can result in confusion. One person may answer a question posed by someone in another country while that person is still talking, and the resulting stilted conversation rapidly loses sense and flow.

In order for the visual and audio information to be collected, the system requires cameras and microphones. The camera collects the visual and the microphone collects the audio. A high level design component of the system, then, is its ability to match the video and audio streams properly so that the lips of the person speaking are synchronised with the sounds coming out of his or her mouth.

To play back the transmitted data, the system must also have a screen of some kind. The display device must further be linked to speakers outputting the audio information. The design and placement of speakers in relation to the screen can be important: the human ear is a sensitive device itself, and can identify if a voice is coming from somewhere other than the image that looks as though it is doing the "talking".

The video conferencing system is tied together by a computer which is essentially any processing unit capable of taking the disparate signals, decoding them from their streamed packets and running them through the required outputs. The same processing unit must simultaneously be sending its own coded data packets to the other part of the video conferencing solution.

This is a concept inherent in all video conferencing solutions that there be a minimum of two units in different locations.

Cool Ideas for Your Home Theater

So you have your home theater equipment and you're ready to set up your new room, but you want to make sure you make it, well, as cool as possible. It's already pretty special that you get to set up this room for your family. Why not add a few special touches that will make it excellent. Here are some ideas making your home theater really cool.

1. Go vintage

Use history's theaters as a model for yours. Think of those decadent 1920s theaters with the big gold double doors. Even if you don't get the doors, you can still model your room off of those elegant red carpets and red plush seats. Consider covering the walls with wood paneling and vintage sconces that give the room a rich feeling when they're on. If you want to really drive the idea home, get those chairs monogrammed. This Parisian opera house feel is great for classic movie buffs and people who love all things vintage.

2. Go man cave

If your theater is mostly going to serve as a man cave for sports game viewing, choose decor that imitates a sports bar feel. Choose wood molding and simple recessed lighting. Use neutral paint to emphasize the manly feel of the room. Use leather seating to increase the feeling of relaxing and enjoying the games. Granite bars going in front of the seating will be a great place to serve beer and snacks. Or, if that's too elaborate, you can get the seats that have a cup holder attached to them and use trays to serve food.

3. Go simple

If your home theater is more prominent in your house, you may not want a novelty room front and center. If you want to incorporate your home theater into the rest of you house's decor, match the paint and lighting to reflect that. Choose light walls. Since you may not be able to set up stadium style seating, you can just build one level above the ground level. This way, people can sit on the floor and on the couch above without feeling crammed.

4. Go modern

If you like clean lines and want to emphasize the techie feel of the home theater choose a concrete bar for the back of the room and concrete walls. Choose square chairs that emphasize strong lines and make the lighting just as angular. The result will be Star Trek meets Pottery Barn, and it will be beautiful.

5. Go kid friendly

If the home theater is mostly going to be for the kids, consider letting them weigh in. Of course, you might not be able to model the theater after a princess castle or spider man, but you can get some ideas that can be translated into a more civilized space. Consider hanging pictures of the kids' favorite cartoon characters or getting colorful sconces that make the space fun for kids but still tasteful enough for adults.

Once you've decided on your video equipment and you've started to set up the technology, you'll want to start considering the design of the room. It's great that you'll have a new fun room for the family, but it can be that much more fun if you make the room really cool -- whatever cool means to you and your family.
