## 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.

## Claims

### Claim 1

A computer-implemented method of 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, wherein each of the plurality of storylines is specific to one player of a plurality of different human players of the multiplayer video game, for broadcasting to at least one computing device, said method comprising:
defining, in at least one server remote from the at least one computing device, a function to identify the plurality of storylines;

determining, in the at least one server, an overall rank for each of the plurality of storylines by associating said at least one factor with the base rank, wherein the overall rank is determined at a predetermined frequency in the game;

### Claim 6 (depends on 1)

### Claim 7 (depends on 1)

The computer-implemented method of claim 1, wherein the one or more rules 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 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 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, wherein each of the plurality of storylines is specific to one player of a plurality of different human players of the multiplayer video game, for broadcasting 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 broadcast 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 the plurality of different 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 broadcast 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;
a processor in said at least one server, said processor executing a plurality of executable programmatic instructions to:
define a function to identify the plurality of storylines;
define at least one base criterion for ranking each of the plurality of storylines;
determine a base rank for each of the plurality of storylines, the base rank being a function of the at least one base criterion;
define one or more factors to weight the base rank, wherein the one or more factors is a function of a first value representative of a relationship between each player and each other player of the plurality of different human players in the multiplayer video game, a second value representative of an orientation of each player relative to each other player of the plurality of different human players in the multiplayer video game, and a third factor representative of a degree of an unobstructed view between each player and each other player of the plurality of different human players in the multiplayer video game;
determine an overall rank for each of the plurality of storylines by associating the at least one factor with the base rank, wherein a value of the at least one factor has an increasing or decreasing effect on the overall ranking; and
subject to one or more rules, programmatically moving the virtual camera to capture one of the plurality of storylines determined to have a highest overall ranking among the plurality of storylines; and
broadcasting the one of the plurality of storylines determined to have a highest overall ranking among the plurality of storylines to the plurality of spectator modules.
