Abstract

Devices and methods are disclosed for controlling content within a device environment through interaction among electronic devices of the environment. The device has a transmitter, receiver, memory storing interaction rules and content rules and a processor for implementing the interaction rules and content rules in association with the transmitter, receiver, and other devices of the environment. Methods involve obtaining content information of the media about to be played and comparing the content information to the content rules stored at a device. An instruction about playback of the media content is generated. Methods may also involve seeking rights information for media content and determining whether rights information exists for identified media content in response to the request. When rights information does exist for the identified media content, a message is sent that includes the rights information.

based upon the comparison, directing a message to the first device, wherein the message includes an instruction about operation of the first device upon the media content.

2. The method of claim 1, wherein the content rules describe whether media content should be played, the method further comprising when the comparison indicates that the content is not to be played, directing a message to the first device, wherein the message includes an instruction to stop playing the media.

3. The method of claim 2, further comprising:

receiving the message at the first device;

interpreting the instruction in the message to stop playing the media; and

stopping the playing of the media.

4. The method of claim 3, further comprising:

from the received message, creating a rule at the first device that indicates that the content information of the media is not to be played;

upon subsequent attempts to play the media at the first device, comparing the content information of the media to the created rule at the first device; and

in response to the comparison at the first device, stopping the playing of the media.

5. The method of claim 2, wherein the content rules include a maximum permissible rating of media content and wherein the content information includes a rating of the media content, and wherein the step of comparing the content rules to the content information comprises comparing the maximum permissible rating to the rating of the media content to determine whether the rating of the media content exceeds the maximum permissible rating.

6. The method of claim 5, wherein the first device has content rules specifying a maximum permissible rating different than the content rules of the second device, the method further comprising:

when the comparison indicates that the content can be played, directing the message to the first device, wherein the message includes an instruction to begin playing the media;

receiving the message at the first device from the second device;

comparing the rating of the media content to the maximum permissible rating of the content rules of the first device;

when the maximum permissible rating of the content rules of the first device are higher than the rating of the media content and when the message instructs the first device to begin playing the media, then beginning the playing of the media; and

when the maximum permissible rating of the content rules of the first device are higher than the rating of the media content and when the message instructs the first device to stop playing the media, then stopping the playing of the media.

7. The method of claim 2, wherein the content rules include an indication of rights to the media content and wherein the content information includes an identification of the media content, and wherein the step of comparing the content rules to the content information comprises comparing the indication of rights to the identification of the media content to determine whether a right to play the identified media content exists.

8. The method of claim 2, further comprising:

delaying playing the media at the first device;

when the comparison indicates that the content is to be played, directing a message to the first device that includes an instruction to start playing the media;

receiving the message to start playing at the first device;

interpreting the instruction in the message to start playing the media; and

starting the playing of the media.

9. The method of claim 1, wherein the content rules include playback settings for media content and the content information includes an identification of the media content, and wherein the step of comparing the content rules to the content information comprises comparing the playback settings to the identification of the media content to determine appropriate playback settings to include in the instruction.

10. The method of claim 1, wherein the content rules include maximum playback settings for media content and the content information includes an identification of the media content, and wherein the step of comparing the content rules to the content information comprises comparing the maximum playback settings to the identification of the media content to determine the maximum playback settings to include in the instruction.

11. The method of claim 1, further comprising:

receiving at the second device a change of state message sent from a third device, the message indicating a change of state of the third device that includes a user selection of one or more content rules for a second media content; and

creating one or more content rules for the second media content at the second device based on the message from the third device, the one or more content rules at the second device corresponding to the one or more content rules specified by the user selection at the third device.

12. A method of establishing content rules that control content playback through device interaction in an environment having a plurality of devices where one or more devices play media within the environment and one or more other devices maintain rights information for media content that governs whether the media content may be played, the method comprising:

sending a request from a first device that plays media content to a second device that maintains rights information for media content, the request seeking rights information for media content and including an identification of the media content;

receiving the request at the second device;

determining whether rights information exists for the identified media content at the second device; and

when rights information exists at the second device for the identified media content, sending a message to the first device that includes the rights information.

13. The method of claim 12, further comprising:

when the rights information is sent to the first device, flagging the rights information at the second device as borrowed.

14. The method of claim 13, further comprising:

sending a message from a third device to the second device, the message requesting that the third device receive authorization based on the rights information at the second device to play the media content;

receiving the message from the third device at the second device;

checking the rights information for the media content at the second device; and

when the rights information is flagged as borrowed, sending a message to the third device that indicates that the third device should stop playing the media content.

15. A device for establishing content control in an environment having a plurality of devices where one or more devices play media within the environment and at least one device maintains content rules, the device comprising:

a transmitter;

a receiver;

a memory that stores interaction rules of the device for interacting with the at least one device maintaining content rules to exercise content control;
