本标准定义了1080行和2160行映射格式，如下所述；1080线映射指定:将表2中列出的1920 x 1080和2048 x 1080像素的图像格式映射为40位虚拟接口的四个并行10位数据流（称为数据流1、数据流2、数据流3和数据流4），通过两个3G/2位串行接口（SD1和SD2）将这些数据流映射到两个3G/2位串行接口。2160线映射指定:将表3中列出的3840 x 2160和4096 x 2160像素的图像格式映射为40位虚拟接口的四个并行10位数据流（称为数据流1、数据流2、数据流3和数据流4），然后通过两个20位虚拟接口将这四个10位数据流映射到双链路3 Gb/s串行接口（3G-SDI链路1和链路2）。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、有效载荷标识符和时间码。 实现不需要包括对本标准中包含的所有格式的支持。实施者应在商业出版物中指出支持的格式。

This standard defines 1080-line and 2160-linemapping formats as described below;1080-line mapping specifies:The mapping of the image formats of 1920 x 1080 and 2048 x 1080 pixels listed in Table 2 into four parallel 10-bit data streams (known as data stream one, data stream two, data stream three and data stream four) of a 40-bit virtual interface, followed by the mapping of these four 10-bit data streams onto the Dual Link 3 Gb/s Serial Interface (3G-SDI Link 1 and Link 2) via two 20-bit virtual interfaces.2160-line mapping specifies:The mapping of the image formats of 3840 x 2160 and 4096 x 2160 pixels listed in Table 3 into four parallel 10-bit data streams (known as data stream one, data stream two, data stream three and data stream four) of a 40-bit virtual interface, followed by the mapping of these four 10-bit data streams on to the Dual Link 3 Gb/s Serial Interface (3G-SDI Link 1 and Link 2) via two 20-bit virtual interfaces.This standard also defines the carriage of ancillary data such as the audio data, the audio control packets, the payload identifier and the time code.It is not necessary for implementations to include support for all formats that are included in this standard. Implementers should indicate supported formats in commercial publications.
