The Video Buffering Verifier (VBV) is a theoretical MPEG video buffer model, used to ensure that an encoded video stream can be correctly buffered, and played back at the decoder device. By definition, the VBV shall not overflow nor underflow when its input is a compliant stream, (except in the case of low_delay).
Even on fast networks like LTE 4G, slow start times and re-buffering will occur during times of congestion or high network utilization. If the chosen bitrate is low, on the other hand, the video quality will be lower – thereby reducing the customer’s quality of experience. There are a number of ways of dealing with these challenges.
