Hi. I have a concern about how to improve the app performance when there is a video playing in the background.
For example, my app has a browse page floats over a video player. When user opens the browse page, the video is still playing behind.
The browse page will need to send a WebAPI request each time user press UP or DOWN button. -> Faster network response means faster UI update for this browse page's items.

My question is "Should I lower my background video resolution, so that the device can have more network bandwidth and power for the browse page?". 

I found some mentions about this on Roku site, such as:

• "There are delays while the video is loading (it is therefore recommended to use a low-res video for something unimportant like a background video), but once it is loaded, there are no further performance decreases that can be attributed to the inclusion of the video." - https://sdkdocs.roku.com/display/sdkdoc/Designing+for+Device+Capabilities[/color]

However, It sounds strange to me that the high resolution video playback in the background doesn't affect the overall network performance of Roku app.

Many thanks for your support.
