Enabling local split-screen multiplayer experiences using remote multiplayer game support

A method, implemented at a computer system that includes a processor, the method comprising:

• establishing a plurality of game streams, in which:
• each game stream corresponds to a different instance of a multiplayer game, which includes remote multiplayer support, but which lacks local multiplayer support, and
• each game stream corresponds to a different user identifier of a plurality of user identifiers, each the plurality of user identifiers being joined to a single multiplayer session of the multiplayer game using the remote multiplayer support of the multiplayer game;
• identifying a plurality of gaming interface devices connected to one or more user input/output interfaces, wherein the plurality of gaming interface devices are co-located with a display interface;
• associating each of the plurality of gaming interface devices with a different game stream of the plurality of game streams;
• outputting, to the display interface, a composite stream of the plurality of game streams that simultaneously includes each of the plurality of game streams in a split-screen display format for display at a single display device;
• and
• while outputting the composite stream of the plurality of game streams, causing one or more input signals received from each of the plurality of gaming interface devices to be routed to its associated game stream.

A non-transitory computer-readable medium that stores computer-executable instructions that are executable by a processing system to at least:

• establish a plurality of game streams, in which:
• each game stream comprises one or more downstream data channels and one or more upstream data channels,
• each game stream corresponds to a different instance of a multiplayer game, which includes remote multiplayer support, but which lacks local multiplayer support, and
• each game stream corresponds to a different user identifier of a plurality of user identifiers, each the plurality of user identifiers being joined to a single multiplayer session of the multiplayer game using the remote multiplayer support of the multiplayer game;
• identify a plurality of gaming interface devices connected to one or more user input/output interfaces, wherein the plurality of gaming interface devices are co-located with a display interface;
• associate each of the plurality of gaming interface devices with a different game stream of the plurality of game streams;
• output, to the display interface, a composite stream of the plurality of game streams that simultaneously includes each of the plurality of game streams in a split-screen display format for display at a single display device;
• and
• while outputting the composite stream of the plurality of game streams, cause one or more input signals received from each of the plurality of gaming interface devices to be routed to its associated game stream and outputs generated by each gaming stream to be routed to its associated gaming interface device.
