Methods and apparatus for monitoring video games
View Patent ↗Methods and apparatus for monitoring video games are disclosed. An example method disclosed herein comprises monitoring game content corresponding to a game medium played by a game console, processing the game content to determine a set of metering data, and cross-referencing the set of metering data with a set of reference data corresponding to a set of known games.
1. A method to monitor exposure to video game content, the method comprising:
determining a set of measurement data corresponding to a set of video game content sources of a composite video game presentation to be presented by a video game console, the set of measurement data including first data indicating whether first content associated with a first video game content source is actually included by the video game console in the video game presentation, the set of measurement data including second data indicating whether second content associated with at least one of the first video game content source or a second video game content source is cached in the video game console for possible later inclusion in the video game presentation depending upon a later point-of-view of a player of the video game during game play, the set of measurement data further comprising a memory signature based on a sequence of memory accesses of a video game medium; and
reporting exposure to the composite video game presentation based on the set of measurement data.
2. A method as defined in claim 1 wherein the set of measurement data further comprises a code associated with at least one of the set of video game content sources.
3. A method as defined in claim 2 wherein the code is generated during game play for inclusion with the at least one of the set of video game content sources.
4. A method as defined in claim 1 wherein the set of measurement data further comprises a signature corresponding to at least one of the set of video game content sources.
5. A method as defined in claim 1 wherein the set of measurement data further comprises information determined by a digital bus analyzer in communication with the video game console used to present the video game content.
6. A method as defined in claim 1 wherein the set of measurement data further comprises information determined by a software meter executing in the video game console used to present the video game content.
7. A method as defined in claim 1 wherein the set of measurement data further comprises control information transferred between the video game console and a game controller coupled with the video game console.
8. A method as defined in claim 1 wherein the set of measurement data further comprises network access information associated with the video game console.
9. A method as defined in claim 8 wherein the network access information corresponds to interactions between a local video game console and a remote video game console.
10. A method as defined in claim 1 wherein the sequence of memory accesses occurs during video game initialization.
11. A method as defined in claim 1 wherein the sequence of memory accesses occurs during at least one of preparation or presentation of the composite video game content presentation.
12. A method to combine measurements of a video game presentation to generate ratings information, the method comprising:
determining, with a processor, an identity of a video game corresponding to the video game presentation by detecting a signature comprising a pattern of memory addresses accessed during reading of a video game medium by a video game console to execute the video game, the video game medium storing the video game, the pattern of accessed memory addresses forming an identifier representative of the identity of the video game;
determining measurement data corresponding to active game play; and
generating the ratings information based on the video game identity and the measurement data.
13. A method as defined in claim 12 wherein determining the identity of the video game comprises determining whether the video game medium is present in the video game console.
14. A method as defined in claim 12 wherein detecting the pattern of memory addresses comprises detecting a series of memory addresses of the game medium accessed during an initialization of the video game console.
15. A method as defined in claim 12 wherein the measurement data corresponds to control information transferred between the video game console and a game controller coupled with the video game console.
16. A method as defined in claim 12 wherein the measurement data corresponds to game status information associated with game content cached to prepare the video game presentation.
17. A method as defined in claim 12 wherein the measurement data corresponds to at least one of a number or identities of local users participating in the active game play.
18. A method as defined in claim 12 wherein the measurement data comprises at least one of time intervals associated with active game play or a duration of active game play.
19. A method as defined in claim 12 wherein determining the measurement data corresponding to active game play comprises determining whether a network connection of the video game console is active.
20. A video game monitor comprising:
an input to receive input data corresponding to a set of video game content sources of a composite video game presentation to be presented by a video game console;
a processor to determine a set of measurement data based on the input data, the set of measurement data including first data to indicate whether first content of a first video game content source is actually included by the video game console in the video game presentation, the set of measurement data including second data to indicate whether second content associated with at least one of the first video game content source or a second video game content source is cached in the video game console for possible later inclusion in the video game presentation depending upon a later point-of-view of a player during game play, the set of measurement data further comprising a memory signature based on a sequence of memory accesses of a video game medium; and
an output to report exposure to the composite video game presentation based on the set of measurement data.
21. A video game monitor as defined in claim 20 wherein the input corresponds to an interface with the video game console.
22. A video game monitor as defined in claim 21 wherein the interface is to communicate with a software meter executing in the video game console.
23. A video game monitor as defined in claim 21 wherein the interface is to communicate with a digital bus of the video game console.
24. A video game monitor as defined in claim 21 wherein the interface is to communicate with a game controller in communication with the video game console.
25. A video game monitor as defined in claim 21 wherein the interface is to communicate with a networking interface of the video game console.
26. A video game monitor as defined in claim 20 wherein the input is to interface with at least one of an audio output or a video output of the video game console.
27. A video game monitor as defined in claim 20 wherein the input corresponds to an interface to a sensor.
28. A video game monitor as defined in claim 20 wherein the processor comprises a code detector to detect a code included in the input data and associated with at least one of the set of video game content sources.
29. A video game monitor as defined in claim 20 wherein the signature is a first signature, and the processor comprises a signature generator to generate a second signature based on the input data and associated with at least one of the set of video game content sources.
30. A video game monitor as defined in claim 20 wherein the input data comprises digital bus data corresponding to the video game console and the processor comprises a bus analyzer to process the digital bus data to determine video game content measurement data.
31. A video game monitor as defined in claim 20 wherein the input data comprises metering data determined by a software meter that is to execute in the video game console and the processor is to process the metering data to determine video game content measurement data.
