Applying a High Fidelity Noise Management before the encoding process reduces the load of the encoder
* The ability of the encoder to recognize motion in a video sequence and to define the motion vectors can be badly influenced by noise. Motion vector accuracy is essential for a high quality video encoding process.
* When noise is present, the encoder will be forced to interpret noise as motion and this leads to faulty motion vectors consuming unnecessary bandwidth..
* Statistical Multiplexing: When a video service carries a lot of noise, it requires more bandwidth. Bandwidth is finite and depends e.g. on the used modulation. Thus extra bandwidth allocated on one service, results in taking bandwidth from others. A noisy service has the potential to cause another services to suffer. If there is excessive noise at one service within a statistical multiplex, the quality of several services can be decreased.
