This slide offers more information about the performance of bidirectional control for automotive systems. As mentioned before, this type of control is continuous and EMI friendly. A closer look will help explain this form of control. Again, blue represents the forward-speed, high-speed video data and the orange represents the low-speed, backchannel data. Note the blanking period in the forward channel.  Traditionally, video has a blanking interval that occurs with every horizontal line and with every vertical frame. At the end of the line there is a time period when no data is sent and at the end of the frame there is also a time period when no lines of data are sent. This illustrates how CRTs were previously driven, when there was an actual beam drawing the image on the display. At the end of a line, the beam would have to retrace back to the beginning and this becomes the horizontal blanking time. At the end of a frame, the beam would also have to retrace from the lower right hand corner of the display screen to the upper left hand corner to start over and this becomes vertical blanking. This has persisted for legacy reasons into LCD displays where the blanking intervals are not needed or can be very small. This slide also shows the forward-channel data illustrating a blanking interval and then showing that the low-speed data is being transmitted continuously. This solution is EMI friendly because one can see that the backchannel data is switching equally and opposite on both the positive and negative ends of the differential pair. This means that no changes are being done to the common mode signal of the differential. Low common mode change means no additional emissions. Finally, this is a low latency solution. The fact that customers can send control data at the same time as forward data means that there is a low waiting period.  In addition, there is no waiting for blanking. The I²C data and any of the critical GPIO signals are being sent in real time, making this ideal for situations where customers want to synchronize multiple cameras. If customers want to send a synchronization pulse from the host controller to three cameras, this can all happen without being dependent on video timing.
