The codec is considered to be an integral part of computing because this is the device which is essential in your computer if you want any actual work done within the computer involving a signal and streaming of data. The primary function of this encoding device is to ensure that encoding work or decoding work is done inside your computer. Several words have come together into a combination to actually form the word codec including “coder” and “decoder” which signifies compression of a signal.
As computers started developing, the modem was used primarily to do this entire work of coding and encoding. It was built to be a sort of modulator which did the important work of converting all the data that was fed in to the computer through the connection line. Once this signal was received by the computer it was once again converted back. With the gradual progression of computing devices and everything involved in the computing world, a development took place that finally enabled the CODEC to carry out this important function. Only the process became a lot less complicated and involved only the process of decoding and coding without any process of compression.
There are essentially several different types of CODEC and they are all designed to perform specific functions which can include something like a video codec. This helps in the compression of a video in the digital form so that it can be viewed in a compressed form within discs available in the market. This has almost revolutionized the entire functioning of computer programming in the market because now it is easier to access videos and other such audio video devices that help in the entire process of watching better quality videos at home.
The endec is also a different type of encoder based on the model of a codec. This is a recent development in the world of computing. Back when things were hardly as well developed, the codec was actually more of a hardware component. The entire process through which a codec actually functions is actually really very interesting. The process involves compression of data that has been fed into the computer through some sort of a data cable line or telephone like device. The codec was then expected to use the complicated mechanism of analog-digital conversion to bring about a change in the compressed files so that they could be immediately output for display. The signal that was ultimately received had to go through the process of a separate video compressor which added the final few touches to have the ultimate end product.
Just like the video codec, there are also audio codec which ensure that the digitally transmitted data in the audio format requires conversion so that it can finally be heard in a music system or MP3. The entire process perhaps requires a lot of work to be done but actually a codec is an amazing innovation in the world of computing because it adds a whole new dimension to the world of computing.
Some of the important codecs are also referred to as the lossy codecs. It has rather a peculiar name called “lossy” because it often ends up compromising the entire quality of a file while it is in the process of compressing it. Such types of codecs often use algorithms to ensure that the conversion work is done and some form of compression is achieved. The files that the lossy codec ultimately ends up converting usually can be stored in the recent amazing developments called Blu-ray discs along with other types of devices like CD, DVD or just the hard disk of the computer memory.
Just like there is a lossy codec where a certain amount of information is saved, there are also codecs which ensure that there is no ultimate loss once the compression work is actually done. For people who want such large files copied or converted it becomes essential that the quality of the file is properly maintained and in order to ensure that it is always a good idea to use the lossless codecs which does the compression work but ultimately does not result in any kind of loss in the file. It is highly likely that all of this data requires processing which is always the case for plenty of video and audio files, in which case it is always best to use the lossless codec instead to have the file preserved in its original form even after compression.
It is also quite interesting to note that certain types of media footage actually need to be encoded, often because of the type of motion involved. This is mostly obvious in sports where motion needs to be recorded. This is what the codec specifically needs to focus on in this particular instance. The working behind each codec is extremely unique and quite different in comparison to others since each involves work of a specific type. The codec working for one piece of digital media is necessarily different from the work that goes behind a codec that is used to transform signals in a cell phone.
A codec can essentially vary in size depending upon the kind of work that it carries out. There are several devices which function to help stream both audio and video signals actually. The codecs which have a lower bit rate allow some types of distortions. They vary in prices and can be downloaded online itself. They are essential for most of the work that is done in the world of computing and programming which makes them essential for computers to work. With more and more developments in the world of computers audio and video codec have become integral to the proper functioning to enable people to use the digital media in any which way they would prefer. There are several complications involved in the entire process of encoding and decoding which makes it even more valuable and important as a component of computing which will remain incomplete without it.
