Resumo


The Brazilian Digital TV System (SBTVD) started signal transmission in S˜ao Paulo on 2 December 2007. Currently, all the Brazilian main cities already have DTV channels available. The adoption of the H.264/MPEG-4 AVC standard provides advanced technologies for encoding digital video signals with high definition video. This standard, also allows transmission of three-dimensional video, but this is not considered by SBTVD yet. This research aims to study the encoding of three-dimensional video content with H.264/MPEG-4 AVC standard, and the insertion of these encoded signals in the SBTVD broadcasting stream. Was investigated techniques for capturing video from two and more cameras, encoding three-dimensional video streams, and transmission of 3D video in the Brazilian Digital TV system. The multiple views were coded with the side-byside technique as well as with multiple-view coding. The videos were transmitted, decoded, and analyzed in a laboratory simulation environment. The objective quality of each video was measured within a wide range of transmission bit rate, and we concluded that good quality 3D video is possible to be allocated in the transmission stream.
