The most recent network technologies are enabling a variety of new applications, thanks to the provision of increased bandwidth and better management of Quality of Service. Nevertheless, telemedical services involving multimedia data are still lagging behind, due to the concern of the end users, that is, clinicians and also patients, about the low quality(More)
— Scalable multiple description video coding (MDC) provides adaptability to bandwidth variations and receiving device characteristics, and can improve error robustness in multimedia networks. In this paper, a scalable MDC scheme is proposed for stereoscopic 3D video. Scalable MDC has previously been applied to 2D video but not to 3D video. The proposed(More)
—In this paper, an Unequal Error Protection (UEP) scheme for the transmission of 3-D (Three-Dimensional) video over WiMAX communication channel is proposed. The colour plus depth map stereoscopic video is coded with backward compatibility using a Scalable Video Coding (SVC) architecture, where users with conventional video decoders/receivers can receive the(More)
In the near future, many conventional video applications are likely to be replaced by immersive video to provide a sense of ldquobeing there.rdquo This transition is facilitated by the recent advancement of 3D capture, coding, transmission, and display technologies. Stereoscopic video is the simplest form of 3D video available in the literature. ldquoColor(More)
Enabling 3D video in e-health applications results in the provision of more natural viewing conditions and improved diagnosis. Recent advances in wireless communications, network technologies and 3D video capture/display mechanisms enable the replacement of 2D video applications of current healthcare services with 3D video, to provide improved perception(More)
Stereoscopic video is one of the simplest forms of multi view video, which can be easily adapted for communication applications. Much current research is based on colour and depth map stereoscopic video, due to its reduced bandwidth requirements and backward compatibility. Existing immersive media research is more focused on application processing than(More)
—New 3D video applications and services are emerging to fulfill increasing user demand. This effort is well supported by the increasing 3D video content including user generated content (e.g., through 3D capture/display enabled mobile phones), technological advancements (e.g., HD 3D video capture and processing methods), affordable 3D displays, and(More)
