Tech Papers 2021: The paper introduces Size-Aware Rate Adaptation (SARA) logic for the dash.js client, utilizing pre-encoded segment size information to enhance adaptive bitrate decisions. SARA aims to improve overall viewer experience by mitigating the impact of content-aware encoding's variable segment sizes.
In HTTP adaptive streaming, the client makes rate adaptation decisions based on the measured network bandwidth and buffer fullness. This simplifies the adaptation logic, however, it does often produce noticeable quality fluctuations during the streaming session. With content-aware encoding, one can improve the visual quality without...
