A patent trio for GameChat have been published by JPO today. I’ll touch on only a few key points below. Please refer to the source docs for more info.
a. Switch 2 GameChat is facilitated by two types of servers:
- Management servers identify and connect users to form chat groups
- Transmission servers receive and relay video streams within a chat group
b. The transmitting Switch sends the camera video (143 in image 1 below)—plus an image mask (153) for user headshot—to the receiving Switches. Using the mask, a receiving Switch can display the user video w/o the background (A in image 2), cropped (B), as is (C), or w/ the background blurred (D).
c. Since the camera video may be magnified (A & B in image 1 below), its zoom factor is also sent from the transmitter to receivers. When the zoom factor is too high (B; low image quality), a “[user] too far away” message is shown on the receiving Switch (image 2).
d. If the user isn’t in frame (C in image 1 below) or disables camera streaming (D), a “muted” image is transmitted instead of camera. On the receiver, a “face not visible” or “streaming disallowed” message is shown (images 2-3). Either the muted image (imege 2) or user initial (image 3) can be used as the avatar.
e. The receiver may be set up to not show any camera feeds (e.g. parental control). Compared to an unrestricted unit (image 1 below), the restricted unit (image 2) hides camera feeds (156-3 & 156-4) and blocks gameplay streams with embedded camera images (150-4). Instead of blocking, other treatments are also possible (image 3).
