An Efficient Logo Insertion Method for Video Coding in HEVC

Inserting a logo into HEVC video streams is highly demanded in video applications. In this paper, we present an efficient logo insertion method for video coding in HEVC. To reduce the impact of inserted logo, the proposed method mitigates the encoding dependence on logo by partitioning the video frame into separated regions. For lossless coding region, we reduce the bit rate overhead of lossless coding according to an error propagation model. For information reusing region, we partly re-encode the quality-loss area to maintain the encoding quality. The computational complexity is reduced by reusing information. Experimental results show that the proposed method achieves a significant speedup ratio of 52 times on average with only 1.43% bit rate increase compared with direct encoding using unmodified HM software.
