272:. In the OpenLDI version of DC balance coding, one of the seven serialized bits indicates whether the coding scheme needs to invert the other six bits transmitted in the clock period to maintain DC balance. Therefore, each LVDS pair other than the clock pair effectively transmits six bits per clock cycle. However, OpenLDI lost the video-transfer standards competition to

FPD-Link III's embedded control channel uses the I2C bus protocol between the source and destination in the first implementations (however, it is not limited to I2C). The I2C master can read and write to all the slaves on the other side of the FPD-Link III chipset, which is effectively transparent to

was introduced in 2010. Further improving FPD-Link II, FPD-Link III's major feature is embedding a bidirectional communication channel on the same differential pair. This bidirectional channel transfers control signals between source and destination in addition to the clock and streaming video data.

was introduced in 2006 and is an improved version of FPD-Link. National
Semiconductor designed it specifically for automotive infotainment and camera interface applications. FPD-Link II embeds the clock in the data signal and therefore uses only one differential pair to transmit both the clock and

There are additional benefits from FPD-Link II. For example, the car makers appreciate the increased cable length even with reduced cable cost. This is because of the embedded clock feature that eliminates the timing skew between clock and data signals. This was the limiting factor to cables with
