subject: What Is A Codec? And How Do They Work? [print this page] A Codec refers to an algorithm or a program that is quite often embedded in a hardware piece like an IP Phone, ATA, etc. In case of VOIP, a codec can be used for converting voice signals into digital data and transmitted over any network or through the internet when a VOIP call is made. The term codec is actually used for a combination of two words. Namely: compressor/ decompressor or for coder/decoder. Codecs are essentially used for encoding / decoding, compression/ decompression or for encryption/ decryption. Let us now understand how this works, 0330 Numbers.
Knowing about Encoding/Decoding
Normally, when we speak over a regular PSTN phone, our voice is transmitted the analogue way over the phone network. However, when you are talking over a VOIP, the voice gets converted into digital signals. It is this conversion that is known as encoding and can only a codec can achieve it. Once the encoding is done, it gets transmitted to its destination where it is decoded back into analogue form so that the person receiving the call is able to understand and hear clearly, 03 Numbers.
The Compression Stage
With bandwidth being scarce, most companies are looking at options to send more data at a time and enhance its overall performance. One way of doing this is by making sure that the data you send is lighter. This is where a codec is used to compress the digital data and make it less bulky. The compression process is quite complex where large data is stored in smaller spaces, otherwise known as digital bits. Normally, during the compression stage, the digital data is restricted to a packet or structure that is ideal to the compression algorithm. This compressed data is transmitted through the network and upon reaching its intended destination the data is decompressed to its original form so that it can be decoded. However, in most instances you may not need to decompress the data back to its original state since it is already available in a usable state,0871 Numbers.
Now, let us see how the codec works when it is used for encryption. If you want to achieve the highest possible security for your 0300 Numbers or 0800 numbers or 0845 Numbers or any other Freephone Numbers, encryption is probably the best tool available today. In the encryption process the data is converted into an indecipherable state so that even if it is intercepted by some unauthorized elements, what you send remains confidential. Only upon reaching the intended destination, this data can be decrypted into its original form, 0800 Numbers.
Finally, a codec is an excellent option to transmit your data in a safe and secure manner.
