H.264 is well known compression standard for raw video. Data hiding using general techniques will not sustain under this scheme. The authors propose a data hiding approach in IPCM block. Where these IPCM encoded macro blocks are modified in order to hide the desired data. In general video, the numbers of IPCM blocks generated are very less. A method is proposed to increase the number of IPCM blocks generated in H.264 algorithm, by which more data can be hidden.
