Hello Mr. Taichi,
I think you are asking how the data for the different inputs (OSR1,2; OSG1,2; OSB1,2 and GPI:5) gets mapped into the output data buses serialized data.
That is described in the datasheet table 13 "Bit Formats", where R, G, B (bits 0-9), and GPI (1:5) positions are spelled out, depending on the format used.
Figure 8 and Figure 9 show the latency from input timing signals to data output for Ch1 and Ch2 samples. Since there are 2 inputs of each color, the data in the link alternates between that sampled at input 1 {Ch.1(n), Ch.1(n+1), ....} and that sampled at input 2 {Ch.2(n), Ch.2(n+1), ....} shown within Figure 8 and Figure 9 as labeled on "TXCLK+" waveform. Using Figure 13 "LVDS Output Pulse Positions", the position of every bit in Table 13 is identified.
Output Pulse Positions:
