Abstract

Text content embedded with multimedia content is provided from a content provider to a client device. The multimedia content may be provided to the client device separate from the text content. In particular, multimedia content metadata indicating a storage location of the multimedia content may be provided to the client device after the text content. The client device may request the multimedia content from the content provider based on the multimedia content metadata. The content provider may send the requested multimedia content to the client device after receiving an authenticated version of the multimedia content metadata.

Claims

1. A computer-implemented method, comprising:

under control of one or more content provider servers configured with specific executable instructions,

receiving a request from a client device for an electronic book;

sending a text content file to the client device in response to receiving the request for the electronic book, the text content file including text content of the electronic book and a multimedia content reference header, the multimedia content reference header indicating that the electronic book includes multimedia content and the multimedia content reference header indicating an identifier of the electronic book;

receiving a request from the client device for multimedia content metadata, the request for the multimedia content metadata including the identifier of the electronic book;

generating a multimedia content retrieval uniform resource locator (URL) indicating a storage location of a particular version of multimedia content of a plurality of versions of multimedia content of the electronic book, each version of the multimedia content is capable of being rendered by a client device with a specific set of multimedia content rendering capabilities;

sending multimedia content metadata to the client device, the multimedia content metadata including a callback URL and a query string including the multimedia content retrieval URL;

receiving a request from the client device including the callback URL and the query string;

sending a signed multimedia content retrieval URL to the client device; and

providing the particular version of the multimedia content to the client device in response to receiving the signed multimedia content retrieval URL from the client device.

2. The computer-implemented method of claim 1, wherein the signed multimedia content retrieval URL expires after a predetermined period of time.

3. The computer-implemented method of claim 1, wherein the particular version of the multimedia content provided to the client device is based on a subscription associated with the client device.

4. The computer-implemented method of claim 1, further comprising sending an indication to the client device that an update of the particular version of the multimedia content is available.

5. The computer-implemented method of claim 4, further comprising:

receiving a request from the client device for additional multimedia content metadata associated with the update of the particular version of the multimedia content; and

sending the additional multimedia content metadata to the client device, the additional multimedia content metadata including the callback URL and a query string including an additional multimedia content retrieval URL specifying a storage location of the update of the particular version of the multimedia content.

6. A computer-implemented method, comprising:

under control of a client device configured with specific executable instructions,

sending a first request to a content provider to purchase an electronic book;

receiving text content of the electronic book and an indication that the electronic book includes multimedia content;

obtaining multimedia content metadata from the content provider, the multimedia content metadata indicating a first uniform resource locator (URL) and a second URL;

extracting the second URL from the multimedia content metadata;

generating a second request for the content provider to provide a signed version of the second URL, the second request including the first URL and a query string including the second URL;

receiving, from the content provider, the signed version of the second URL;

sending a third request to the content provider for the multimedia content of the electronic book, the third request including the signed version of the second URL; and

receiving the multimedia content of the electronic book from the content provider.

7. The computer-implemented method of claim 6, wherein the multimedia content of the electronic book includes a plurality of files including one or more audio files, one or more video files, one or more audiovisual files, one or more image files, or a combination thereof.

8. The computer-implemented method of claim 6, wherein the multimedia content metadata includes a file size of the multimedia content of the electronic book.

9. The computer-implemented method of claim 8, further comprising providing an indication of progress of retrieving the multimedia content of the electronic book based on the file size of the multimedia content.

10. The computer-implemented method of claim 6, further comprising:

determining that the client device is incapable of rendering the multimedia content of the electronic book; and

providing the multimedia content of the electronic book to an additional client device that is capable of rendering the multimedia content of the electronic book.

11. A client device comprising:

one or more processors;

memory accessible by the one or more processors, the memory storing one or more modules that include computer-readable instructions executable by the one or more processors to perform acts comprising;

sending a first request to the content provider to purchase an electronic book;

receiving a text content file based at least partly on the first request for the electronic book, the text content file including text content of the electronic book and an indication that the electronic book includes multimedia content;

sending a second request to the content provider for multimedia content metadata at least partly based on the indication that the electronic book includes the multimedia content;

receiving the multimedia content metadata of the electronic book from the content provider, a portion of the multimedia content metadata indicating a storage location of the multimedia content of the electronic book;

generating a third request to the content provider for a signed version of the storage location of the multimedia content;

identifying a portion of the multimedia content of the electronic book to retrieve based on behavior of a user of the client device; and

retrieving the portion of the multimedia content from the content provider based at least partly on the signed version of the storage location of the multimedia content.

12. The client device of claim 11, wherein the acts further comprise sending multimedia content rendering capabilities information of the client device to the content provider.

13. The client device of claim 12, wherein the multimedia content is compatible with the client device according to the multimedia content rendering capabilities of the client device.

14. The client device of claim 11, wherein the acts further comprise identifying the portion of the multimedia content of the electronic book to retrieve by identifying a current page of the electronic book being rendered via the client device.

15. The client device of claim 11, wherein the acts further comprise identifying the portion of the multimedia content of the electronic book to retrieve by predicting subsequent multimedia content items of the electronic book to be consumed via the client device.

16. The client device of claim 11, wherein the acts further comprise identifying the portion of the multimedia content to retrieve based at least partly on receiving an indication of user selection of one or more multimedia content items of the electronic book.

17. The client device of claim 11, wherein the acts further comprise caching the portion of the multimedia content retrieved from the content provider.

18. The client device of claim 11, wherein the acts further comprise presenting the text content and the multimedia content of the electronic book via one or more output devices of the client device.

19. The client device of claim 18, wherein the acts further comprise rendering a user interface including links selectable to provide at least one item of the multimedia content via the one or more output devices of the client device.
