5 New Technologies to change the era
Do you also dream of that time when it would be possible for you to view the 3D movies at your home while drinking your cup of tea? Just imagine the situation where you suddenly tap on your gigabit-wireless-connected tablet, and then watch a 3D movie on the thin HDTV hanging somewhere on the wall with the help of super speedy USB connection and HD transmitter. It all appears to be a dream but soon it would be a reality.
Now, it would be possible for you to collect all information about the actors within few seconds with the help of reality contact lenses and a virtual keyboard. All this information would be visible in the form of a webpage that would be showing list of all actors with their movies and videos.
Now there will be no separation between speed and content. They will be paired consistently within mobiles, laptops, desktops, and various home-entertainment systems. It has been seen that new methods of using video specially those that include 3D depth or visual overlays require more speed, computational power and storage.
To meet all this demands, several new technologies have been invented. For the connection purposes, devices like USB 3.0, 802.11ad, and 802.11ac are used. For moving media like videos HTML5 is used that can display videos and contents of all kind at very fast speed. Besides this, 3D TV is also used that can further add some image depth and provide better experience for watching the 3D movies.
The new USB 3.0 is designed specially to preserve the backward compatibility of the devices as it allows the older cables to plug back into the new jacks also.
USB have been in use since long. Though these days it is considered to be less important for present-day mobile devices and computers but no one can disagree to the fact that it still provides better speed than any other device. It is compatible and therefore makes the user free from the havoc of the cables.
The new version of the USB is USB 3.0 that has very fast processing speed. It has speeded up the transfer rate between PC and peripheral devices and therefore has made the task of printing, scanning and transferring very fast.
The USB 3.0 is expected to have transfer rate up to 5 to 10 times faster than any other standard peripherals. This device has dubbed its super speed by the folks who are responsible for controlling the testing and the licensing at the USB Forum. It is believed that USB 3.0 will deliver speed of more than 3.1 gigabits per second.
USB 3.0 is an upgrade of the USB 2.0 which was half duplex. It has an advantage over its others successors. It is capable of shooting full-speed data in two directions at a time. It is full duplex. It also accepts both 1.0 and 2.0 plugs for the backward compatibility unlike the 3.0 cables that can only work with 3.0 jacks.
This technology could be a game-changer for device connectivity. A modern computer includes jacks so that it can accommodate USB 2.0, Ethernet, FireWire 400 and 800, DVI (Display Port), and eSATA. But by using USB 3.0 there is no need to have separate jacks for all these. Only a single jack for the Ethernet needs to be there, and rest of them can be handled easily by the USB 3.0. So, USB 3.0 acts as a game changer for the entire device connectivity. USB 3.0 ports are capable of delivering data to the monitors, retrieving data from the scanners, and helps in exchanging data with the hard drives. They offer improved speed which is as fast as that of the flash memory drives.
USB 3.0 allows uncompressed 1080p video to get download at very high speed of 60 frames per second. Says this means that USB 3.0 can enable a camcorder to forgo the video compression at very good speed. This enables the user to stream live video from a simple camcorder and does not require any kind of video processing. This video can then store easily on an internal drive for the purpose of rapid transfer that was earlier not possible without making use of heavy compression. The USB 3.0 is regarded as the efficient substitute of blue ray players.
The USB 3.0 also has capability to turn computers in the real charging stations. They are much better than the USB 2.0 that can only produce 100 milliamperes (mA) of charge for every port, as they can produce up to 150mA of current per device.
Most of the mobile phones are moving towards the USB and are using them as the standard plug for getting their mobiles charged. This is very common in the countries like Europe and Asia and it is also expected that the U.S is also going to follow the same trend. This will then completely demolish the era of wall warts or the AC adapters of all types.
It is also expected that with the growing importance of the USB 3.0, future desktop computers are expected to have two internal hubs that could support several ports easily and can provide easy access towards the charging station. Each of the hubs would be having up to six ports supporting the full amperage. USB 3.0 is not useful only for the desktops, it provides same benefits to the laptop machines as well that could completely rely on USB ports for better charging.
The USB 3.0 shows higher speed that can accelerate the data transfers of more than 20GB per minute. This increased speed can then surely make the task of taking backups of huge amount of data like images, downloaded media and movies very fast and easy.
Most of the manufacturers are taking advantages of the USB 3.0, and it predicted that in the near future it would be produced and consumed in mass. They are going to be more popular in the mobile devices and the consumer electronics. There is a plenty of potential for getting this new standard out very fast.

// Video Streaming Over Wi-Fi
Wi-Fi is technology that is used commonly very well and when it will be combined with Video streaming the result is going to be miraculous. In the near future, Wi-Fi would be mainly using protocols like 802.11ac and 802.11ad. Both of them are capable of carrying the multiple video streams and can also operate at very high speeds.
At this point of time though it may sound incredible that it is possible to view high-definition, 3D movie that is stored on the flash drive very easily on the wall mounted HDTV by just plugging the drive into the laptop and then transfer it to the network file server with the help of gigabit Wi-Fi connection within a couple of minutes. But this is actually possible now by the help of video streaming over Wi-Fi.
These days, the wired Ethernet has achieved higher data speed than the Wi-Fi, but that does not mean that the Wi-Fi is lagging behind somewhere because wireless standards groups are making constant efforts to figure out the different ways so that Wi-Fi can catch up. By the year 2012, two new protocols are expected to hit the market. These are 802.11ac and 802.11ad that would be made responsible to handle the over-the-air data transmission at very high speed of up to 1 gbps.
This will result in the users to have various multiple high-definition video and gaming streams that would be active across one house and within a single room. Though the central media servers, and Blu-ray players, can sit anywhere inside the home, and can stream the content towards the end devices at any location but Wi-Fi enabled video streaming would not have that facility.
It is expected that the 802.11ac and the 802.11ad standards would be well suited for the home use, but their applications would be extending far beyond the range of homes. The 802.11ac standard has the responsibility of updating the 802.11n, which is considered to be the latest and the greatest of all wireless local area networking (WLAN) technologies. The 802.11n began with the 802.11b. The 802.11ac improves the wireless networking performance and gives the speed of about 600 mbps. In practice, it has been that the net data that is carried by the 802.11ac is likely to be between the 300 mbps and the 400 mbps which is quite better than the 802.11n setup. The 802.11ac has the capability of carrying various compressed video streams together over a single channel at the same time. Users may also assign the individual streams that are running on the unique frequencies to various separate channels. 802.11ac also makes use of many antennas for the purpose of receiving and sending the data wirelessly.
Today the data is transferred over the wireless lines by compressing first and moreover the data received is not lossless. Till the date, wired cables are used to transfer the video in lossless format and for that purpose it is important to compress the data which is later on processed by the HDTV. The 802.1ac also does not have the capability of transferring the video without compression. This is because for uncompressed data or video very high speed is required.
To remove the shortcomings of the 802.11ac, the development of the 802.11ad took place. It abandons the bands of 2.4GHz and 5GHz of the spectrum. This is the region where the Wi-Fi actually works. These bands are replaced by the 60GHz spectrum. By this replacement it has now become possible to transfer the uncompressed video at the speed of 1gbps.
But the 802.11ad has one disadvantage. It can be used for the short distance data transfers. This means the data can be transferred within rooms. The main reason for this is that the long waves that operate in 60GHz signals cannot penetrate walls and the furniture, and are also absorbed by the oxygen readily. As a result they cannot penetrate deeper and therefore cannot transfer long distance data. The 802.11ad support high speed video transfers and also permit the users to move their files or sync data between various devices at the speeds that can approach that of the USB 3.0. They are thousand times faster than the Bluetooth 2.
The 802.11ad is the best protocol to make use of the 60GHz band than the other protocols. The Wireless HD trade group, a consortium of consumer electronics. Though at present 802.11ad doesn’t address specifically the video, but it is considered as a generic technology responsible for accommodating many different kinds of data.
It is believed that the awesome combination of the protocols like 802.11ac and 802.11ad with the USB 3.0, are capable of delivering very high speed live videos. They can position all the clusters of computer equipment and the entertainment hardware in your home. USB 3.0 and the gigabit Ethernet can connect devices that are located in a cabinet but 802.11ac can link several clusters across the home; and 802.11ad can carry data to the mobile devices, HDTV displays, and other kind of gears within a single room.
This improved technology will result in fewer cables and wires, with better speeds, and high-quality video playback.
Earlier when televisions were introduced nobody ever though that they would also be able to use this device to view 2D and 3D movies. But now, this is possible with the advent of the HDTV’s or the high definition televisions. They are considered to produce the next wave in the home viewing in the form of 3DTV and a 2D picture along with some kind of stereoscopic depth.
Today creating a 3d movie is no more a difficult task and as a result there are many filmmakers who have started making the 2d or the 3D movies. These movies require a library of the depth-enhanced features. Earlier to view them the users need to use special 3D glasses. The colorizing technology has increased its interest in the black-and-white films that were produced during the early 1980’s.
The 3D videos are more immersive, includes more true and life experience, and they are substantively very different from anything what the viewers have watched earlier. In the commercial theaters, the 3D projection mostly involves the technique of the superimposing of the polarized or colored images on every frame. These were then viewed by the viewers by wearing the “passive” glasses that were used to reveal different images for each eye. These different images were then synthesized by the brain as two images that creates convincing notion of the depth.
Viewing 3D videos at home is completely different form the way it is watched on the theatres. At homes, this completely relies on the alternating right and left views for the successive frames. This can be viewed on the HDTVs that generally operate at the speed of 120Hz and therefore executes 120 cycles of refreshes per second. Due to this, the ability of the HDTV to alternate between the left eye and right eye images becomes very fast as compared to the brain and thus, the human eye follows that already exists.
Still to view the 3DTV displays the viewers will require the “active” glasses that have the capability to rapidly fire the shutters so that they can alternate the view for each eye. Though active glasses are very expensive at present, but it is expected that their price are going to drop as the 3D will roll out. At this time most of the designers are in their development phase and are producing 3D set that won’t be requiring any kind of glasses.
Companies like Sony and Panasonic have already announced their plans regarding the production of the various 3D-capable displays. Recently Panasonic has demonstrated a large-screen version of such HDTV’s that are expected to be out in the year 2010. It is expected that before HDTV, the premium 3D TV are first going to be rolled out. Creation and distribution of the enough 3D contents to get the feedback of the consumers can be very challenging. Due to the lack of efficient means of viewing 3D videos most of the filmmakers are making and adapting only few features of the 3D video. But to fill the gap developers are working on the “synthetic 3D” versions of the existing films that can be used for the tracking, pattern cues, focus, and for splitting the images.
The terrestrial cables and the IPTV networks are believed to distribute the 3D content in the coming days. The bandwidth for such networks will make use of typical HD broadcasts to deliver the video and would be requiring new video compression techniques.
Augmented Reality in Mobile Devices
Have you ever dreamt of the situation where it would be possible to paint the information from the eyes into augmented reality in the form of some imaginary picture? Recently a scientist was found on working such bionic contact lens.
Now, try to imagine the situation, where you watched a movie on your home theatre and liked it very much so decided to watch it on big screen. But you don’t know the location of the theatre. So what can you do? Well, you can take out your smart phone and dock it on the dashboard. Now the driving directions get superimposed on your car’s windshield. As you follow the directions you come across superimpositions of many building and finally your destination. Sounds really interesting but still like a dream. In the coming future, it will be no more a dream.
The time is no more too far when augmented reality will become an everyday experience. Augmented reality generally refers to a catchall term that is used for overlaying whatever we see through the computer-generated data or through the visual substitutions. The main idea behind this technology is to enhance the ability of the user to interact with the things that are all around by providing the users with the information that is immediately relevant with those things.
The augmented reality though exists today but it is there in the form of the “heads-down” screens in the smart phones. They need to be further worked upon to create heads-on screen. They have a very wide scope that can be enhanced further so that they can be used in everyday life.
There are many companies that are trying to release the programs that could overlay the position and produce the context-based data that can be fed to a continuous video camera. The data for these programs comes from various types of radios and different sensors placed at different locations and are built into the modern smart phones. They are present in the smart phones in the form of GPS radios where they are used for identifying the position of the satellite and to get data from it, accelerometers that are used for measuring the changes in the speed and orientation, and magnetometers that are used for finding the position with respect to the magnetic north.
The most famous application of the augmented reality today in the mobile phones is the application that is known as the Nearest Places. This application is used to find the names and the locations of the subway stops, museums, parks, restaurants, and various other places of user’s interest. These places are shown on the top of the Smartphone’s video feed. The information keeps on changing as the user changes his position. This information basically overlays the surroundings.
It is expected that the field of the augmented reality is going to dominate the market in very short span of time. Besides this, there are other types of the prototype applications that are used to display the information about the particular coordinates in the 3D models. It helps the user to know the coordinates where he can walk around. It also used in the form of the animations where the details keep on updating themselves in 3D with respect to the position of the user. But it has been found that this technology is not yet mature that can be used for the handhelds as they demand more-precise positioning mechanism. It has been found that each smart generation of the mobile phones require more and more better sensors for the purpose of data insertion
Augmented reality performs the task of provide not only the additional information, but also provides the enhanced vision. It is expected that the augmented reality will help the infrared cameras that are mounted on the car front to illuminate a far destination object and to represent it as a bright image on the display of the windshield. It will also help the Radar signals and various wireless receivers to detect and to display the cars that have gone too far to be located and are out of sight. It will converge the complete application responsible for hosting the GPS and the traffic reporting to just a single piece of glass.
There are many developers who are trying to work on the ways that would help to put the display directly onto the eyeball. Besides this, they are also trying to develop the technology that could help in embedding the video circuitry into some wearable contact lenses. This would help the user to see the continuous and the context-based data through those eye lenses by simply wearing them.
It is expected that the augmented reality is going to become a kind of the routine navigation and an interaction aid for the mobile devices. This technology will also be very useful for the game developers and would help them to overlay a complete digital game over the environment reality.

Using HTML 5 you can view 3D movies on your mobile as well as computers. You can download the movie on both the devices at same speed and enjoy the same capabilities. HTML 5 is best to be used with 4G phones.
Now, you don’t have to face the problem of the optimization of browsers. Web sites developed in html 5 works well with all the browsers no matter whether it is internet explorer 3 or 4. This new flavor of HTML (Hyper text markup language) offers a platform for writing the standard programs for the web pages. It is the up gradation of the previous versions that removes all the boundations.
The websites designed with HTML5 are best for including audio, video, or other interactive plug-ins. It provides users with a better, richer, and faster Web experience.
Here there are no boundations on the formats of the audio or video or other plugins that are to be used. It is compatible with all formats. Besides this, there is no need to take help of other third-party plug-ins or in house technologies to combine multimedia with the web pages. It makes the task of the programmer and the user very easy. It makes very easy to download the live videos that may be both 2D and 3D. This means that the Website designers and Web developers do not have to waste their time in dealing with the multiple incompatible formats to create the same kind of user experience for every different browser.
HTML 5 has been designed especially for the mobile phones as their browsers at present have only limited amount of multimedia support. HTML 5 helps to improve the capabilities of these types of browsers. For example: in the case of the iPhone Safari browser it cannot handle the adobe flash very efficiently. Since flash is the prime medium of delivering the video content across the web pages and the browsers, the HTML5 helps to embed this facility in the mobile phone browsers.
Today with the development of the HTML5 most of the operating system makers and the manufacturers of the browsers are trying to follow the footsteps of the HTML5. Among the list the main followers are the Google Chrome, opera, Apple Safari, ng and Web Kit. They all are supporting HTML 5.
HTML 5 is ready to create a boom in the market. Just last draft needs to be completed then it will be also there in the list of the supporters of the World Wide Web. Though Microsoft also has declared that the internet explorer 8 is also going to support HTML5 but still it is hesitating as it cannot take the risk of giving the entire market to the HTML5.
