ABSTRACT The conventional full-redundant duplicate transmission scheme,
which is often adopted in video transmission that requires high
reliability such as contribution and primary distribution, has a
drawback in that the efficiency of utilization of transmission links is
low. In order to improve this, it would be effective to realize
“flat multi-scalable video transmission”, in which the
picture can be reconstructed by using any single channel, while
combining more than one channel leads to the reconstruction of the
picture with even higher quality. In this paper, for this purpose, the
authors propose a “complementary sampling method”. In this
method, the improvement in picture quality is achieved by cancelling out
the coding noise which is included in more than one channel. Moreover,
it is shown that in this scheme, the objective assessment of picture
quality can be performed based only on the received pictures. The
authors hope that this study will help to construct a visual
communication system with high efficiency and high reliability

    ABSTRACT: For contribution and primary distribution of television, i.e., television transmission to broadcasting stations, parallel transmission links that include codecs are often set up for reliability. However, this configuration still faces the following issues: 1) during normal periods, the reserve link is totally wasted and 2) when a failure occurs, the disrupted signal continues to be transmitted until the system switches to the reserve link. In addition, in digital video transmission, automatic assessment of received video quality is an important issue. To address these issues, the authors developed a processing system for parallelly transmitted video signals, which mainly consists of the following three elements: 1) when both links are normal, outputting the average signal of both links reduces compression coding noise and improves picture quality compared to only one link (efficiency); 2) comparison of the pictures from the two links enables failure detection in either link, to switch to the normal link (support of failure detection); and 3) comparison of the two normally decoded pictures enables evaluation of picture quality (automatic coding noise evaluation). This unique system improves the reliability and operational efficiency of conventional parallel video transmission links.

    ABSTRACT: The authors propose a scalable video coding algorithm for low bit rate failure-free video transmission. In the failure-free video transmission, two channels are utilized to transmit the same video source. In the receiver, the video can be reconstructed by any single encoded bitstream. While receiving two encoded bitstreams, the image quality can be improved by combining two bitstreams. We develop a motion vector refinement technique to improve the image quality. In the encoder, the positions of the macroblocks for channel two are shifted by eight pixels from channel one. In the receiver, the motion vectors transmitted in each channel can be refined to more accurate motion vectors with smaller block size when two channels are received. The final decoded image is merged from the two reconstructed images by the two channels. Experimental results show our proposed method has high efficiency and high reliability
