Data Embedding in SHVC Video Using Threshold-Controlled Block Splitting

With the increasing number of video applications, it is essential to resolve issues such as ineffective search content, tampered/forged packet loss, name a few. Data embedding typically utilized one solutions address aforementioned issues. One important requirements data maximize capacity with minimal bit rate overhead while ensuring imperceptibility inserted data. However, varies depending on content and usually leads quality degradation. In this work, threshold-controlled block splitting technique proposed for into SHVC video. Specifically, can be increased by coding host using more small blocks, which achieved tuning parameter in distortion optimization process. Subsequently, predictive syntax elements both intra inter-coded blocks are jointly embed data, ensures that embedded regardless prediction mode used block. Results suggest method achieve trade-off between increase maintaining quality. best case scenario, sequence PartyScene 516.9 kbps an average +7.0% Low Delay P configuration, same 1578.6 +2.9% All Intra configuration.
