free-viewpoint video, 3D-TV, and immersive teleconferencing). Of the various 3D video technologies, multiview video’s capability to provide multiple viewing angles or points of dynamic scenes with high quality and immersive multimedia experience, makes it a key technology for many texture-related 3D applications (e.g. Over the last decade, numerous 3D video technologies, such as holography, augmented and virtual reality, stereoscopic, video with depth information coding and multiview video coding, have been studied (e.g. Consequently, while the quality of network connectivity and bandwidth are improving, demands for high definition (HD) and UHD quality monoscopic and three dimensional (3D) visual communications continue to rise at the same time. Lately, with the growing popularity of video applications, such as video-on-demand (VoD) and introduction of UHD internet protocol televisoin (IPTV) video streaming, it is expected that these applications will constitute 21% of global VoD traffic by 2020. According to Cisco’s Visual Networking Index (VNI) forecast, it is anticipated that: by 2020, 71% of the overall IP traffic used by both business and domestic users would be from non-PC devices, of which 82% would be for visual content communication. The growing influence of these entertainment and interactive applications, ranging from low resolution to ultra-high definition (UHD) video contents, has resulted in steady increase in fixed and mobile network’s traffic. Results show that the proposed codec gives significantly higher coding performance to that of the MV-HEVC codec at low bitrate both subjectively and objectively.Īdvances in video technologies have played a key role in facilitating applications (such as video conferencing, e-learning, video-on-demand, real time surveillance, automation, robotics, and machine vision) in our day to day activities. The proposed MRHEVC-MVC codec has been tested against the standard multiview extension of high efficiency video codec (MV-HEVC) for “Balloon”, “Newspaper1”, “Undo_Dancer”, “Kendo” and ““Poznan_Street” standard multiview video sequences.
The codec’s reference frames structure is designed to efficiently encode frame interleaved multiview videos using a HEVC based mixed resolution codec.
#THE HEVC CODEC FULL#
This has been overcome by super-imposing the low resolution replica of each full resolution frame on their respective decoded picture buffer and setting the remaining space of the frame buffer to zero. However, enabling the HEVC to encode video with different frame resolutions is a challenge due to the coding tree partitioning used by the codec. In this paper, a High Efficiency Video Codec (HEVC) based spatial resolution scaling type of mixed resolution coding model, MRHEVC-MVC, for frame interleaved multiview videos is presented.
There has been increasing demand for multiview video transmission over band limited channel over past years and various techniques have been proposed to fulfil this need.
