## Abstract

In a multiplayer video game, virtual cameras are controlled by continually assessing and ranking storylines relating to the interactions of various players during a game session. A ranking for each storyline may be based on various factors such as, but not limited to, what the players can see, the distance between certain players, nearby game items or in-game. Subsequently, at least one virtual camera is navigated to provide a view of the highest-ranking storyline, subject to certain limitations on how the camera can move, transition, or otherwise display the interactions between players.

The computer-implemented method of claim 4, wherein the base rank for each of the plurality of storylines is inversely related to the virtual distances of each player with respect to each of the other players.

### Claim 6 (depends on 1)

The computer-implemented method of claim 1, wherein the at least one factor is a function of at least one of:
a first value representative of a relationship between each player and each other player in the multiplayer video game;
a second value representative of an orientation of each player relative to each other player in the multiplayer video game; or
a third factor representative of a degree of an unobstructed view between each player and each other player in the multiplayer video game.

### Claim 7 (depends on 1)

The computer-implemented method of claim 1, wherein the one or more rules further limit at least one of rotation, tilt or pan required for the virtual camera to capture the storyline determined to have said highest overall ranking.

### Claim 8 (depends on 1)

The computer-implemented method of claim 1, wherein the one or more rules further require the highest overall ranking of the storyline to exceed an overall ranking of an immediately preceding storyline by a predefined value.

### Claim 9 (depends on 1)

The computer-implemented method of claim 1, wherein the one or more rules further limit at least one of a speed of movement of the virtual camera or an angular speed of rotation of the virtual camera.

### Claim 10

A system for controlling at least one of a navigation, positioning or orientation of a virtual camera configured to capture a plurality of storylines in a multiplayer video game executing on a plurality of gaming devices for transmitting to a plurality of spectator devices, said system comprising:
at least one server for hosting a game session of the multiplayer video game and to transmit said game session to each of a plurality of spectator devices through a network;
a plurality of gaming modules stored on the plurality of gaming devices remote from the at least one server and configured to enable a plurality of human players to play in the game session of the multiplayer video game;
a plurality of spectator modules stored on the plurality of spectator devices remote from the at least one server and configured to enable a plurality of human spectators to view the transmission of the game session, wherein at least a portion of the plurality of spectator modules are executing on at least a portion of the plurality of gaming devices and wherein at least a portion of the plurality of gaming modules are executing on at least a portion of the plurality of spectator devices;
