We propose a new coding technology for 3D video represented by multiple views and the respective depth maps. The proposed technology is demonstrated as an extension of the recently developed high efficiency video coding (HEVC). One base views are compressed into a standard bitstream (like in HEVC). The remaining views and the depth maps are compressed using(More)
In this paper, we present the most efficient coding tools that are used in a new video compression technology for multiple views with the depth maps. This very well performing technology was designed and developed in response to MPEG Call for Proposals on 3D Video Coding Technology. The proposed technology exploits a tool that reduces the side views and the(More)
—During the last two decades, a new technology generation of video compression was introduced about each 9 years. Each new compression-technology generation provides halving of necessary bitrates as compared to the last previous generation. This increasing single-view compression performance is related to increasing compression performance of multiview(More)
— The paper describes watermarking of compressed video bitstreams. This technique is proven to be very fast and robust against various attacks including camcorder recording attack. The watermark is embedded using indirect modifications of transform coefficients in selected P-and B-frames. In the watermarked bitstream there exist sequences of watermarked(More)
The paper deals with multiview video coding using the new technology of High Efficiency Video Coding (HEVC). Implementation of multiview video coding in the framework of HEVC is described together with new specific tools proposed by the authors. Extensive experimental results are reported for compression performance comparison of MVC (ISO 14496-10), HEVC(More)
— A computationally inexpensive watermark schema for MPEG-4 AVC/H.264 streams that use local mark strength adjustment minimizing visible artifacts is presented. The local mark strength adjustment mechanism and watermark embedding mechanism operate on residual data. This approach minimize the number of operations needed for video bitstream decoding and(More)
—Rate-Distortion Optimized Quantization (RDOQ) is an encoding optimization technique that may be modified with no implications to the bitstream compliance with the standard. In the paper, we propose an RDOQ variant with exact cost estimation resulting in higher compression ratios as compared to HEVC Test Model. This improvement is obtained at the cost of(More)
