Visual Protection of HEVC Video by Selective Encryption of CABAC Binstrings.
The proposed construction of video steganography was realized by embedding the secret image into the meaningful cover image of any type of video file using CABAC approaches.

Data is compressed much more efficiently with CABAC than CAVLC; but CABAC encoding needs much more processing power to drive it.
In this frame for speed of encoding CAVLC was used in the base layer and CABAC was used in the three enhancement layers.
Evaluation and decision on modes contribute to CAVLC, CABAC, and EXP-GOLOMB in a simplified way to address the data-handling constraints.
Among several entropy coding methods, when a high profile video service is required, Context Adaptive Binary Arithmetic Coding (CABAC) is most preferred because CABAC achieves a better compression efficiency.
Beyond profile and level, control over H.264 encoding options is minimal; you can set GOP size and B-frame interval and choose your entropy encoding technique (CAVLC or CABAC).
The test conditions are as follows: there is I-B-P view structure, there is test of 200 frames for each sequence, quantization parameter (QP) is chosen with 26, 31, 36, and 41, group of pictures (GOP) size is 8, treeblock size is 64, and context-adaptive binary arithmetic coding (CABAC) is used for entropy coding.

It achieves higher compression efficiency than other standards [2] by using advanced coding techniques such as multiple-reference frame prediction and context-based adaptive binary arithmetic coding (CABAC) [3].
of reference frames: 5, entropy coding method: CABAC. The coding performance is measured by comparing PSNR (peak signal to noise ratio) with- and without deblocking filter.
