新型可靠传输控制系统多分辨率视频流数据

本数据集实体文件由同一源视频按360p、480p、720p、1080p、4K五种分辨率分别转码得到的MP4文件制备而成，每个分辨率再进一步切割成符合HLS（HTTP Live Streaming）协议的M3U8索引文件及一系列TS分片，用于实现自适应码率（Adaptive Bitrate Streaming，ABR）视频传输。数据集内包含同一视频的360p、480p、720p、1080p、4K五档分辨率HLS视频流，视频时长1min35s。每档1个M3U8索引+23个TS分片（共约115个TS文件），外加master.m3u8主索引和若干完整MP4/WEBM备份，总计131个文件。整套数据可部署至Web服务器，配合视频服务器和播放器，可验证在不同链路状态下视频传输和ABR切换的流畅性、稳定性与清晰度表现。实体文件总容量为1.22GB。The entity files of this dataset are derived from the same source video, which is transcoded into MP4 files at five resolution levels: 360p, 480p, 720p, 1080p, and 4K. Each resolution group is further segmented into M3U8 index files and multiple TS segments that comply with the HLS (HTTP Live Streaming) protocol, aiming to support Adaptive Bitrate Streaming (ABR) video transmission. This dataset encompasses HLS video streams of the identical source video across the five aforementioned resolution tiers, with a total duration of 1 minute and 35 seconds. For each tier, there is 1 M3U8 index file paired with 23 TS segments, amounting to approximately 115 TS files in total. Additionally, it includes a master.m3u8 master index and several complete MP4/WEBM backup files, bringing the overall count of files to 131. The entire dataset can be deployed on a web server, and when combined with a video server and player, it enables validation of the fluency, stability, and clarity performance of video transmission and ABR switching under various link conditions. The total storage size of all entity files is 1.22 GB.
