Thanks for the respinse @Noel Walker. As per the requirements can't install any app on TVs, We have to play the video on OOB Web browser which is chromium.
Our idea is, configure the video which is authored by content authors in different CMS, and configure that video page by using LG super sign and distrbute the content.
Unfortuntely, very less support from LG support team.
Thanks,
Venkat
