The conversation between human and AI assistant.
Why do we see numbers or codes on the screen while watching TV?
I see, thanks for explaining that. Are there any other types of icons or symbols that we might see on the screen while watching TV?
Yes, sometimes we might see a mute icon, a volume bar, or a parental control icon. The mute icon is used to indicate when the sound has been turned off, the volume bar is used to show the current sound level, and the parental control icon is used to indicate which rated program is being shown and whether it is appropriate for children.
