In　high　bitrate　information　hiding　techniques,　1　bit　is　embedded　within　each　4　×　4　Discrete　Cosine　Transform　(DCT)　coefficient　block　by　means　of　vector　quantization,　then　the　hidden　bit　can　be　effectively　extracted　in　terminal　end.　In　this　paper　high　bitrate　information　hiding　algorithms　are　summarized,　and　the　scheme　of　video　in　video　is　implemented.　Experimental　result　shows　that　the　host　video　which　is　embedded　numerous　auxiliary　information　have　little　visually　quality　decline.　Peak　Signal　to　Noise　Ratio　(PSNR)Y　of　host　video　only　degrades　0.22dB　in　average,　while　the　hidden　information　has　a　high　percentage　of　survives　and　keeps　a　high　robustness　in　H.264/AVC　compression,　the　average　Bit　Error　Rate(BER)　of　hiding　information　is　0.015%.
