Using HDMI: (probably the easiest method)
1) Follow your device manufacturer's instructions for mirroring your device's display via an HDMI cable.
2) Go to a scripture chapter or general conference talk. If you want to broadcast a specific one, then the one you select in the app should be that one.
3) Tap the "Play" button at the top-right corner of the screen.
4) Select either "Watch" or "Listen."
Using USB:
Prerequisites:
1) A TV that allows you to browse media on a USB device.
2) An app that allows you to access your device's file system. You'll need to move or copy the video file to a folder that the television will see.

1) Go to a scripture chapter or general conference talk.
2) Tap the "Play" button at the top-right corner of the screen. If you want to broadcast a specific one, then the one you select in the app should be that one.
3) Tap "Download media."
4) Tap on either "(Audio)(insert name of content you wish to download)" or "(Video)(insert name of content you wish to download)."
5) When the content is downloaded, use the prerequisite app to move the video file to your device's movie folder. The video file is located at (Full path to Gospel Library app's folder)/1/media. On my device, both the app's folder and the movie folder are located under /storage/sdcard0.
