This topic describes the architecture of RTS SDK.
Alibaba Cloud RTS SDK pulls audios and videos from Global Realtime Transport Network (GRTN), sends them to demuxers and jitter buffers, decodes audios, and frame videos. Then, RTS SDK sends the audios and videos to a frame queue where a player pulls video and audio streams. The player sends audio frames to a renderer and video frames to a decoder, and then sends the decoded frames to another renderer. The video renderer synchronizes the video frames with the audio renderer based on the pts parameter.
