Abstract

Systems and methods for combining streaming media content items for streaming to a client computer across a network are described. In one aspect, a server computer receives a request from a client computer for one or more content items. Responsive to receiving the request, the server computer identifies a data structure that refers to the one or more further content items. The server computer modifies the data structure to reference the requested content items. The server computer provides the content items referenced by the modified data structure to the requesting client computer for streaming media content to a user.

Claims

1. A method for a server computer to automatically provide content to a client computer, the method comprising:

receiving, by the server computer, a request from the client computer for one or more requested content items; and

responsive to receiving the request;

identifying, by the server computer, an original data structure that refers to one or more further content items;

copying, by the server computer, the original data structure to create a copy of the original data structure;

modifying, by the server computer, the copy of the original data structure to reference the requested content items, wherein the copy of the original data structure further comprises a placeholder that identifies a particular point in a sequence where the reference to the requested content is placed; and

providing, by the server computer, the content items referenced by the modified data structure to the client computer for presentation to a user.

2. The method of claim 1:

wherein identifying the original data structure, the original data structure comprises a playlist;

wherein receiving the request, the one or more requested content items comprises streaming media content; and

wherein providing the content items further comprises streaming the content items referred to by the playlist.

3. The method of claim 1, wherein identifying the original data structure, the data original structure comprises a first Web page specification, and the requested content comprises a second Web page specification.

4. The method of claim 1, wherein modifying the copy of the original data structure further comprises adding a plurality of references to the requested content item in the data structure.

5. The method of claim 1, wherein modifying the copy of the original data structure further comprises adding a plural number of references to the requested content item in the data structure, the number being indicated by the request.

6. The method of claim 1, wherein receiving the request, further comprises receiving a variety of requests from the client computer, at least one subset of the variety of requests comprising respective requests to one or more different content items.

7. A server including a processor configured to perform one or more operations comprising:

receiving a plurality of requests from a client for one or more requested content items;

responsive to receiving the request, and for at least a subset of the received requests;

(a) identifying, by the server, an original data structure containing a sequence of references to one or more further content items;

(b) copying the original data structure to create a copy of the original data structure;

(c) modifying, by the server, the copy of the original data structure reference to the requested content items, wherein the copy of the original data structure further comprises a placeholder that identifies a particular point in the sequence where the reference to the requested content is placed; and

(d) communicating, by the server, the content items referenced by the modified data structure to the client.

8. The server of claim 7, wherein the original data structure comprises a playlist, the requested content comprising streaming media content, and wherein the communicating comprises streaming the content items referenced by the modified data structure to the client.

9. The server of claim 7, wherein the original data structure comprises a first Web page specification, and wherein the requested content comprises a second Web page specification.

10. The server of claim 7, wherein modifying the copy of the original data structure comprises including a plurality of references to the requested content item in the data structure.

11. The server of claim 7, wherein modifying the copy of the original data structure comprises including a plural number of references to the requested content item in the data structure, the number being indicated by the request.

12. The server of claim 7, wherein at least a subset of the received requests refer to differing content items.
