Abstract

Systems and methods described herein relate to detecting the existence of unauthorized content in multiuser composite media stream. In particular, multiuser composite media streams can be examined and to determine if these composite streams include unauthorized content such as copyrighted content or nudity, violence, language violations where desired. The multiuser composite media stream can be partitioned into sections associated with broadcasting users and the portions can be analyzed independently. A notification can be provided to, e.g., the broadcasting user responsible for the unauthorized content in response to detection of the unauthorized content.

Claims

1. A system, comprising:

a server that hosts user-uploaded media content, the server including a computer processor that executes the following computer executable components stored in a memory;

a receiving component that receives a multiuser composite media stream that is composed of multiple media streams from a set of broadcasting users;

a partition component that identifies a portion of the multiuser composite media stream, the portion associated with a broadcasting user from the set of broadcasting users;

a detection component that examines the portion of the multiuser composite media stream and identifies unauthorized content included in the portion; and

a notice component that provides to the broadcasting user a notification that relates to the unauthorized content.

2. The system of claim 1, wherein the receiving component receives the multiuser composite media stream substantially concurrently to a real-time, live broadcast of the multiuser composite media stream to a set of content consumers.

3. The system of claim 1, wherein the portion of the multiuser composite media stream is a cropped portion of the multiuser composition media stream that depicts a media stream associated with the broadcasting user and excludes other portions of the multiuser composite media stream associated with other broadcasting users included in the set of broadcasting users.

4. The system of claim 1, wherein the portion of the multiuser composite media stream is an individual media stream associated with the broadcasting user.

5. The system of claim 1, further comprising an enforcement component that updates a presentation of the multiuser composite media stream in response to identification of the unauthorized content.

6. The system of claim 5, wherein the enforcement component issues instructions to terminate the presentation of the multiuser composite media stream.

7. The system of claim 5, wherein the enforcement component issues instructions to exclude media associated with the broadcasting user from the presentation of the multiuser composite media stream.

8. The system of claim 1, wherein the notice component flags an account associated with the broadcasting user in response to identification of the unauthorized content.

9. The system of claim 1, further comprising a compilation component that assembles the multiuser composite media stream from a collection of individual streams associated with the set of broadcasting users.

10. The system of claim 9, further comprising an authorization component that forbids participation by a user with an account that is flagged for unauthorized content.

11. A method, comprising:

employing a computer-based processor to execute computer executable components stored within a memory to perform the following;

receiving a multiuser composite media stream composed of respective individual media streams from a set of broadcasting users;

identifying a portion of the multiuser composite media stream corresponding to a broadcasting user from the set of broadcasting users;

identifying unauthorized content included in the portion of the multiuser composite media stream; and

transmitting to the broadcasting user a notification relating to the unauthorized content.

12. The method of claim 11, wherein the identifying the portion of the multiuser composite media stream relates to identifying a cropped portion of the multiuser composite media stream associated with the broadcasting user excluding other portions of the multiuser composite media stream associated with other broadcasting users included in the set of broadcasting users.

13. The method of claim 11, wherein the identifying the portion of the multiuser composite media stream relates to identifying a particular individual media stream associated with the broadcasting user.

14. The method of claim 11, further comprising terminating a presentation of the multiuser composite media stream in response to the identifying unauthorized content.

15. The method of claim 11, further comprising excluding media associated with the broadcasting user from a presentation of the multiuser composite media stream in response to the identifying unauthorized content.

16. The method of claim 11, further comprising flagging an account associated with the broadcasting user in response to the identifying unauthorized content.

17. The method of claim 11, further comprising forbidding a user from joining the set of broadcasting users in response to an account associated with the user being flagged for an unauthorized content violation.

18. The method of claim 11, further comprising constructing the multiuser composite media stream based upon multiple individual streams associated with the set of broadcasting users.

19. The method of claim 18, further comprising arranging depictions of the individual streams included in the multiuser composite media stream based upon activity associated with the set of broadcasting users.

20. A system, comprising:

means for receiving a multiuser composite media stream composed of respective individual media streams from a set of broadcasting users;

means for identifying a portion of the multiuser composite media stream that corresponds to a broadcasting user from the set of broadcasting users;

means for identifying unauthorized content included in the portion of the multiuser composite media stream; and

means for transmitting to the broadcasting user a notification relating to the unauthorized content.
