All About Megapixel Ratings


Megapixel Ratings
It’s no stretch in saying that the digital encoders we design and manufacture at Telairity are some of the most competitively trailblazing products of their kind on the market today. The bit rate speed, high resolution, platform versatility, and cost-effectiveness of our encoders, decoders, and mobile encoders all attest to this, as do our sales-figures in any number of key international markets. But while our products are certainly innovative in the way they perform (and outperform), there isn’t any reason why the basic concepts behind the technology should remain mysterious to the curious bystander. 

In other words, you don’t have to be a “techie” to understand the basic rocket science.
Take the key concept of megapixel rating, for instance – a quality our encoders are rightfully known for, and also one of the driving selling-points behind new commercial technologies like the 4G network. Just why – exactly – is it a “good thing” to have a high megapixel rating? 

Well, for starters, having a high pixel rating results in the production of a higher quality digital image – one which, if brought into closer resolution, the quality wouldn’t blur or distort. The trick to having a high pixel rating – and thereby a high-resolution image - isn’t in the sheer number of pixels involved in producing the image, but rather the size of each individual pixel within a given, constrained amount of space. 

The more pixels per square inch (ppi), the better, and here’s why: since the resolution limit for the unaided human eye is around 0.1 mm, any pixel that’s smaller than 0.1 mm in diameter will translate as “seamless” when zoomed into higher focus. That’s the whole working concept behind the iPhone 4: with 960 x 640 pixels squeezed into a 3.5 inch diagonal screen, the iPhone 4’s graphics more than exceed the natural boundaries imposed by human vision: with 326 ppi on the iPhone 4’s screen display, every image appears un-blurred no matter how closely you zoom.  

Telairity has developed the encoding technology that not only reduces drastically the cost, speed, and bandwidth by which digital information gets relayed, but also places a high emphasis on high-ppi graphics. As the commercial digital world continues to trend towards the ever faster, ever more visually precise consumer experience, Telairity is flying at the forefront of the wave.
