Separate power planes for the ADV7511 are strongly recommended. There are several methods to do this. These are 2 different ways to do it and they both work. Also we recommend a solid ground plane.
Below is one example of how I decoupled the ADV7625 CVDD power rail. The filter is a Murata NFM21PC105B1A3 which is a power line filter that has similar response as the LC filters. And it is in a 0805 package. From the schematic, single dot caps are 0402 caps and triple dot caps are 0805. The 47uF caps are tied to the bulk power supply but placed close to the filter. The 10uF is just a bulk cap after the filter. The 100nF and 10nF are selected and place close to the pins. The Murata filter is much smaller then the inductor used for the other designs.
Generally you will want: Bulk Cap -> Filter -> Bulk cap -> 100nF -> 10nF -> pin
The number of 100uF and 10nF need to be adjusted based on layout and number of power rail pins.
(If two pins are right next to each other, you do not need a 10nF cap for each pin, they can share one 10nF cap.)
The filter blocks noise generated from one pin source being injected into a sensitive pin.
As far as the extra 10uH inductor in the power rail, it may just be over kill.
