The adaptive bitrate streaming parameters can specify "video transcoding parameters" and "audio transcoding parameters" of each substream. VOD uses an adaptive bitrate streaming template to represent the set of parameters for easy configuration. For more information, please see Adaptive Bitrate Streaming. Adaptive bitrate streaming has the following benefits: Dynamically selects the appropriate bitrate for playback based on the changes in the network bandwidth of devices, helping you conserve bandwidth while delivering a smoother viewing experience. Supports customizing video and audio parameters to meet your diverse needs. Supports multi-resolution, multi-bitrate substream modes that can be configured easily and flexibly. ©2013-2019 Tencent Cloud. All rights reserved. Page 11 of 24
