Percentage average alteration in video file size and compression ratio when I, B or P-frames are considered as a cover using techniques for the scenario that the data payload of 32768 bits are embedded in the MPEG-2 encoder.

Percentage average alteration in video file size and compression ratio when I, B or P-frames are considered as a cover using techniques for the scenario that the data payload of 32768 bits are embedded in the MPEG-2 encoder.本数据集量化了采用适配向MPEG-2编码器嵌入32768比特数据负载这一场景的隐写技术时，分别以I帧、B帧、P帧（I-frame, B-frame, P-frame）作为隐写载体的情况下，视频文件大小与压缩比的平均变化百分比。
