Transcoding is the conversion of one transmission format into another using various algorithms to achieve wider support of formats at different quality levels.In the context of video communications, transcoding will usually take place between video codec formats and voice codec formats.

The operation of transcoding brings with it several challenges:

• Transcoding increaes the latency due to the added operations required
• Transcoding may reduce the quality of the data being transcoded
• Transcoding requires computing resources
