US 2022/0021920 A1 · COMMUNICATION ENTITY AND A METHOD FOR TRANSMITTING A VIDEO DATA STREAM

Abstract

A communication entity for transmitting a video data stream at a target transmission bit rate and corresponding method are provided. The communication entity comprises: a first scheduling instance configured to determine a preliminary transmission bit rate for forwarding the video data stream towards the user equipment; and a second scheduling instance configured to determine the target transmission bit rate based on the preliminary transmission bit rate and a set of video bit rates, the set of video bit rates comprising a first video bit rate associated with a first video quality and a second video bit rate associated with a second video quality, the first video bit rate being smaller than the second video bit rate, wherein the second scheduling instance is configured to select the preliminary transmission bit rate as the target transmission bit rate if the preliminary transmission bit rate does not exceed the first video bit rate.
