This standard defines 1080-line and 2160-linemapping formats as described below; - 1080-line mapping specifies: - The mapping of the image formats of 1920 × 1080 and 2048 × 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 × 2160 and 4096 × 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.
