When a video delivery system provides different representations of the same sequence, solutions can be found in simulcast coding, scalable coding, and transcoding. The major downside of transcoding is the additional complexity needed to re-encode the video sequence in its new form. When one fidelity version of the video stream should be transmitted over the(More)
Transcoding is a fast technique for video adaptation, which offers great flexibility for changing the characteristics of already coded video sequences in order to match the properties of the terminal display devices and the bandwidth availability of the transmission networks. For reduction of the bitrate, requantization transcoding is often used. In our(More)
Efficient broadcasting of video content to end-users often requires one or more adaptations of the bitstream, due to varying network conditions and different end-user device characteristics. To ensure a high quality of experience for all end-users, the highest possible quality of the bitstream and, contradictory, connectivity for low bandwidth devices(More)
Scalable video coding (SVC) allows encoded bitstreams to be adapted. However, most bitstreams do not incorporate this scalability so bitstreams have to be adapted multiple times to accommodate for varying network conditions or end-user devices. Each adaptation incorporates an additional loss of quality due to transcoding. To overcome this issue, we propose(More)
Lacking of enough 3D contents has become the bottleneck of 3D technology development. 2D-to-3D conversion can not only solve this problem, but also be compatible with the 2D video format. However, most of the real-time 2D-to-3D conversion methods are limited to some special images/videos. This article proposes a scheme that can be applied to all kinds of(More)
