In 3D-HEVC, single depth intra mode has been applied and has been integrated into depth intra skip mode for efficient depth map coding. With single depth intra mode, one 2N×2N prediction unit (PU) is predicted without high computational prediction process. In this paper, we propose a fast single depth intra mode decision method to address the problem of high computational complexity burden in depth...
Raptor codes are state-of-the-art forward error correction (FEC) solutions for multimedia transmission, which have been applied to unequal error protection (UEP) of multi-layered media such as scalable video coding. In this paper, we address the problem of UEP for single-layered video over packet erasure channels. By exploiting the different priorities of video packets inside a group of pictures (GOP)...
Due to the best effort feature of many existing transmission channels, video streams often suffer from inevitable transmission errors. In this paper, we propose a scheme of robust video transmission based on the state-of-the-art Raptor codes, whose applications are in full swing now. And considering Region of Interest (ROI) often draws much attention in images, the scheme adopts a nested protection...
H.264/AVC is the latest video coding standard from ITU-T. It provides superior and efficient video coding at low bit rates. Flexible macroblocks ordering (FMO) is an error-resilient tool included in H.264/AVC. In this paper, a novel technique for adaptive classification of macroblocks into two slice groups using FMO method is proposed. With our adaptive macroblocks allocation map, simulation results...
During the period of transmission, video data usually suffer from transmission errors inevitably. Intra update is a common approach to stop error propagation. However, damaged images cannot recover until next update in case of errors, which often leads to annoying effect. In this paper, we propose an enhanced leaky prediction approach that enables the region-of-interest (ROI) of images to recover...
Unequal error protection (UEP), which provides important data with more protection, has been proven to be able to produce better quality in image communication. Previous UEP schemes are mostly proposed for single-image or single-program scenarios. Yet few are developed for multiple programs. Inspired by the MPEG-2 transport stream (TS), in this paper we transform the conventional TS packets to be...
Various error control schemes have been addressed in wireless video stream transmission. By combining an adaptive binary arithmetic coding technique with context modeling, CABAC as a normative part of H.264/AVC has achieved a high degree of adaptation and redundancy reduction. However, error propagation still remains a problem because of the property of arithmetic coding. The presented scheme compares...
