Each session of video and audio communication must invoke the use of Codecs to operate. However, in addition to hardware codecs that are manufactured by Polycom and Cisco Systems, many cloud based software tools also enable video conferencing.
Codecs are intended to make video and audio conferencing cross-compatible between hardware systems. While Codecs are often invisible to users, they are extremely important because without them video and audio conferencing would be impossible. The decode process requires a codec also and so coder / decoder functions require devices to include codecs whether they are hardware, software or cloud based. A Codec that allows for the ingest of audio and video is “encoding” those signals into a form that can then be decoded after movement or manipulation. This means that through the use of a Codec, information as represented by sound and video can be encoded and them moved and transformed. That electronic form of sound and video can be transmitted, copied, moved and rendered into other forms. However, there are many different types of codecs including some that are only for audio.Ī Codec allows the ingesting of sound and video into electronic form. It is a standards based codec that many manufacturers have adopted and therefore with this codec, broad cross-compatibility between video enabled devices is possible. The H.264 codec is used in many applications from DVD's to YouTube videos. Coding and decoding video and audio signals is required to convert video and sound into bits of information that can be transmitted, and translated. There are many variants of codecs and they all perform this "encode" and "decode" function with some form of compression or reduction in size of source video and/or audio.Ī Codec can be software based or it can be hardware based. A piece of each word is used to create the commonly used word “Codec”. The word Codec is a combination of two words "coder" and "decoder".
