本标准定义了使用由基于SMPTE ST 425-3数据结构的四对数据流组成的接口传输立体图像（左眼和右眼图像）的方法。左眼图像携带在接口的四个数据流上，右眼图像携带在其他四个数据流上。根据SMPTE ST 425-3的映射规则，将左眼和右眼图像分别映射到相应的四个数据流上。使用本标准传输的立体图像格式为SMPTE ST 425-3中列举的4:2:2和4:4:4图像格式。视频本质和辅助数据的映射结构如SMPTE ST 425-3所定义。本标准还定义了辅助数据的传输，如音频数据、音频控制数据包、有效载荷标识和时间码。 实现不需要包括对所有图像格式的支持，也不需要支持两种映射模式以符合本标准。鼓励实施者在商业出版物中指出支持的格式和支持的映射模式。

This standard defines a means of transporting stereoscopic images (Left eye and Right eye images) using an interface consisting of pairs of four data streams based on the SMPTE ST 425-3 data structures. The Left eye images are carried on four data streams of the interface and the Right eye images are carried on the other four data streams. The Left eye and Right eye images are each mapped onto the respective four data streams in accordance with the mapping rules of SMPTE ST 425-3.The stereoscopic image formats to be transported using this standard are the 4:2:2 and 4:4:4 image formats enumerated in SMPTE ST 425-3. Mapping structures for the video essence and ancillary data are as defined in SMPTE ST 425-3.This standard also defines the carriage of ancillary data such as the audio data, the audio control packets, the payload identifierand the time code.It is not necessary for implementations to include support for all image formats, nor is it a requirement to support both mapping modes to conform to this standard. Implementers are encouraged to indicate supported formats and supported mapping modes in commercial publications.
