Abstract

An experimental service of 3DTV cable broadcasting was made by delivering stereoscopic 3D video to the users in dual HD stream format. Also, an experimental attempt was made to provide backward compatibility for conventional 2D Set-top Boxes (STB) receiving and displaying only one stream of stereoscopic 3D video signal called reference video. For the experimental service, stereoscopic 3D video signals are encoded with 35 Mbps and transmitted over single broadcasting channel by using the existing cable headend and transmission systems. Prototypes of the software-based 3D encoder and 3D STB were also used for the experimental service. Through the experimental broadcasting service, it was possible to provide HD 3DTV broadcasting service under legacy cable environment and to support backward compatibility for the conventional 2D STBs to receive HD broadcasting by using the reference video. A survey revealed that about 60% of the viewers answered the image quality of stereoscopic 3D video in dual HD stream format was better than that in single HD stream format.

采用双高清流的3DTV有线广播实验服务

以双高清流格式向用户传送立体3D视频，开展了3DTV有线广播实验服务。此外，还进行了一项实验尝试，为传统的2D机顶盒(STB)提供向后兼容性，使其只接收和显示一个称为参考视频的立体3D视频信号流。在实验服务中，立体3D视频信号以35mbps的速度编码，并使用现有的电缆头端和传输系统在单个广播信道上传输。基于软件的三维编码器和三维机顶盒样机也用于实验服务。通过实验广播业务，可以在传统有线环境下提供高清3DTV广播服务，并支持传统2D机顶盒使用参考视频接收高清广播的向后兼容。一项调查显示，约60%的观众回答说，双高清流格式的立体3D视频的图像质量优于单高清流格式。
