TDVision Systems Inc. is collaborating with Kronomav to get its 2D+Delta/MVC encoding technology running on the NVIDIA Quadro Digital Video Pipeline platform.
TDVision’s 2D+Delta technology is listed as part of the Multiview Video Coding (MVC) amendment to the H.264 video compression standard recently selected by the Blue-ray Disc Association as “Blu-ray 3D.” In addition, TDVision Systems owns several 3D-related key patents now listed as part of different standard stereoscopic architectures like ISO, MPEG and AVC.
The TDVCodec 2D+Delta system’s claim to fame is that it encodes S3D video by comparing the left and right stereoscopic views and leveraging the redundancies between them. The left view and the correlated delta then are stored into a single stream in such a way as to help ensure backward compatibility on 2D legacy decoders. This encoded content has the benefit of being “In full HD3D where available,” TDVision said.
The system can ingest two gen-locked 3G/HD SDI interfaces from full HD resolution up to 4k per view. Real-time warping and conformance on the input pair of stereoscopic images is achieved by using Kronomav tools and real-time encoding is performed using TDVCodec 2D+Delta method with MPEG2, MPEG4/H.264 and MVC on the fly. According to the team, this universal encoding platform also provides support for 2D and 3D interim-frame-compatible formats.
As such, the 2D+Delta method leads to a reduction of bandwidth usage and cost savings by servicing 2D and 3D viewers with one channel.
According to TDVision CEO Manuel R. Gutierrez Novelo, “We have been NVIDIA development partners for a long time, and the NVIDIA Quadro Digital Video Pipeline is a tremendous platform that enables a gamut of possibilities, unleashing the GPU processing power to encode stereoscopic content in real time at resolutions up to 4K.”
