Android TV apps Design: Video detail & horizontal list of vidoes

We are developing an android tv app in which we need a horizontal lists of videos and on top of the screen there will be a view with some information related to video. So as user selects different videos the top part of screen will be updated with the relevant detail of video. We are using leanback library for android tv. I have checked the DetailSupportFragment but this fragment seems to cover the detail part on top of screen once user navigates using D-pad. What we want is that top detail part should always be visible. Any idea about how DetailSupportFragment can be customized or is there any other alternate solution.
