Can I Send Data, Wakeup Signals and Power on GMSL with Co-Ax cable?

Question

Hello, 
 
 I have a host which shall drive the display. Display have only coaxial cable. No other port to it. 
 
 I want to use GMSL serialised and diseralizer in both devices as shown in the picture. 
 
 I want to send the following on the coax line. 
 1. Power: To power the display LCD and internal Microcontrollers 
 2. Wakeup Pulses: To wake up the display to ready to show the video content 
 3. Data: Send video data to display to the video content

What I know is, 1 and 3 are possible. My question is, 
 a. Is 2 necessary? 
 b. Can we realise 2 if I want to do it? 
 c. Any other wakeup methods possible on coaxial line?

Hi, 
 As per deserilizer datasheet, The devices can enter or exit sleep mode by a command from a local &micro;C or a remote &micro;C using the control channel. 
 Please note that Serial outputs has a wake-up receiver to accept wake-up commands from the attached deserializer and note that Wake-up from the remote side is not supported in coax splitter mode. If the wake-up receiver is disabled, the device can only be woken up from the local control channel. For more details Please refer MAX9277/MAX9281 - 3.12Gbps GMSL Serializers for Coax or STP Output Drive and LVDS Input (analog.com)

Thanks,
