EVS was designed from the ground up to work with packet-switched services such as VoLTE (Voice over LTE). Fraunhofer calls it Full-HD Voice. The EVS codec allows bit rates ranging from 5.9 Kbit/s to 128 Kbit/s, which allows phone service providers to optimize their networks as needed.
It's quite simple, really. The bit rate is the amount of data dedicated to a second of video. So, the higher the bit rate, the better the video quality. The higher the bit rate, the more bandwidth is needed to play back the video. And the higher the bit rate, the more data storage is required per second of video. One usually thinks of a 1920x1080 frame as High Definition whereas a 800x600 or whatever would be of lower quality. So HD is considered better than SD.
