ADV7511 HDMI Transmitter ESD Protection

I'm considering recommending the use of the ADV7511 HDMI Transmitter in a customer project. The project is already using an OMAP3530 host that brings out typical RGB888 video LCD[23:0], hsync, vsync, clk; audio via I2S; and intends to use CEC via 2-way GPIO. The project has no interest in HDCP. Looking at the sparse ADV7511 datasheet, everything looks fairly feasible. It looks like the video would be no problem, audio should be fine using the I2S and the CEC could get picked up via a couple of gpio pins. But I can't tell if the transmitter needs hotplug/static discharge protection which other HDMI chips seem to need in order to ensure they don't get fried by the HDMI cable being hotplugged. I'm trying to find order of magnitude pricing for the ADV7511, for example in 10k volumes, will it be under $10 or over? I'm not at all experienced with HDMI parts so am very interested in any feedback, suggestions or advice.
