Rainbow Technology : Seminar Report|PPT|PDF|DOC|Presentation|Free Download



Rainbow Technology,a breakthrough in digital data storage enables us to store up to a massive 450GB on just a piece of paper. Rainbow Storage is a group of techniques to store digital data in some colors, color combinations and some symbols known as rainbow format, and therefore a rainbow picture will be generated. The technique is used to achieve high-density storage. With the help of Rainbow system we would be watching full-length high-definition videos from a piece of paper!

The main attraction is the cheap paper. The Rainbow technology is feasible because printed text, readable by the human eye is a very wasteful use of the potential capacity of paper to store data. By printing the data encoded in a denser way much higher capacities can be achieved. Paper is, of course, bio-degradable, unlike CDs or DVDs. And sheets of paper also cost a fraction of the cost of a CD or DVD. 

How Is It Possible?



It uses geometric shapes such as squares and hexagons to represent data patterns, instead of the usual binary method that uses ones and zeros to represent data. Besides, color is also used in the Rainbow system, to represent other data elements. Files such as text, images, sounds and video clips are encoded in "rainbow format" as colored circles, triangles, squares and so on, and printed as dense graphics on paper at a density of 2.7GB per square inch. An RVD therefore looks like a print-out of the modern art.


Rainbow Technology


           The paper can then be read through a specially developed scanner and the contents decoded into their original digital format and viewed or played. The Rainbow technology is feasible because printed text, readable by the human eye is a very wasteful use of the potential capacity of paper to store data. By printing the data encoded in a denser way much higher capacities can be achieved. The retrieval of data is done by scanning the paper or the plastic sheet containing the data into a scanner and later reading it over monitor. Instead of using 0s and 1s, we use color dots where each color dot can represent minimum 8 bits (1 byte). The rainbow picture will be highly compressed and can be represented in any color medium. For retrieving the contents from the medium, picture can be captured and data can be generated from the color combinations. "Although environmental light differences and color shading is a problem, it can overcome up to a certain limit by using efficient mapping functions".

Implementation Requirements

         In order to read the Rainbow prints, all that is required is a scanner and specialized software.   Smaller scanners could fit inside laptop computers or mobile phones, and read SIM card-sized RVD's containing 5GB of data. The recording media could be either paper or plastic sheets. The piece of paper or even plastic sheet storing the data has just to be scanned in the scanner and read over the monitor. A scanning drive based on the Rainbow software has simultaneously been developed which will come in smaller sizes to be initially carried with the laptops and later to fit into their bodies.

          The developer is simultaneously moulding the technology into 'Rainbow Cards' which will be of SIM card size and store 5 GB of data equivalent to three films of DVD quality.  

       As 'Rainbow Cards' will become Popular, Rainbow Card Readers will replace CD drives of mobile phone and computer notebooks and will enable more data in portable forms for mini digital readers. Large scale manufacture of the Rainbow card will bring down its cost to just 50 paise.

Demonstration




The reporter of Arab News claims to have seen 450 pages of fully printed foolscap being stored on a 4-square inch piece of Rainbow paper. The reporter also claimed that he was shown a 45-second video clip that was stored using the Rainbow system on a plain piece of paper. Abideen has demonstrated a 45-second video clip being encoded on paper, termed by him, a rainbow video disk - RVD - and then played back through a computer with an RVD scanner attached. In another demonstration he has shown 432 A4 pages of paper rainbow format-encoded and stored on a two-inch by two-inch square of paper.

Once the Rainbow technology is in, soon we would be watching full-length high-definition videos from a piece of paper! With the popularity of the Rainbow Technology, computer or fashion magazines in future need not carry CDs in a pack.

One of the major advantages of the Rainbow system is the fact that it should cost a lot less to produce than the typical polycarbonate DVDs, CDs and now Blu- rays. Huge data banks can be constructed out of Rainbow-based storage medium.
