Abstract

A streaming policy management system and method wherein bandwidth may be allocated based on external device information received from a streaming client device connected to one or more external audio/video (A/V) devices. When a streaming network back office receives a request from the streaming client device for delivery of a particular content, wherein the request includes external device information of one or more external A/V devices connected to the streaming client device, a bandwidth is determined for streaming the particular content to the streaming client device and a request may be made to a content delivery network to create a distribution pipe having the bandwidth to accommodate the delivery of the particular content. A manifest file is provided to the streaming client device that includes one or more pointers that point to content segments of the particular content.

First claim

What is claimed is:

1. A method performed at a client device, the method comprising:
obtaining at the client device from an audio/visual (A/V) device information indicative of one or more resolutions supported by the A/V device and one or more audio formats supported by the A/V device, the information obtained via an HDMI connection between the client device and the A/V device, the A/V device external to the client device;
displaying on a graphical user interface of a local display of the client device, content available for selection, wherein content options associated with the content available for selection that are displayed on the user interface change based on the A/V device information, wherein the local display and the A/V device have different resolutions;
obtaining a manifest file for the selected content, the manifest file comprising URLs for a plurality of versions of the selected content;
obtaining via a network connection a first version of the plurality of versions of the selected content, wherein the first version is obtained based on the A/V device information, and wherein the first version is specifically supported by the A/V device and is not supported by the local display; and
providing the obtained format of the selected content to the A/V device via the HDMI connection.

2. The method of claim 1 wherein the network connection is a Wi-Fi connection.

3. The method of claim 1 wherein the network connection is an ethernet connection.

4. The method of claim 1 wherein each version of the plurality of versions of the selected content has a different bitrate.

5. The method of claim 1 further comprising:
obtaining at the client device from a second A/V device, second A/V device information indicative of one or more resolutions supported by the second A/V device, at least one resolution supported by the second A/V device not supported by the first A/V device; and
obtaining via the network connection a second version of the plurality of versions of the selected content, wherein the second version is different than the first version and is obtained based on the second A/V device information.

6. The method of claim 1 wherein the first version of the selected content is obtained via HTTP Live Streaming.

7. The method of claim 1 wherein the first version of the selected content is composed of a plurality of fixed duration segments.

8. The method of claim 7 wherein the client device obtains different versions of the selected content for different segments of the selected content.

9. A client device, comprising:
an HDMI port for an HDMI connection with an external audio/visual (A/V), the HDMI connection configured to obtain from the A/V device information indicative of one or more resolutions supported by the A/V device and one or more audio formats supported by the A/V device;
a local display that displays a graphical user interface for displaying content available for selection, wherein content options associated with the content available for selection that are displayed on the graphical user interface change based on the obtained A/V device information, wherein the local display and the A/V device have different resolutions; and
a network interface for establishing a network connection, the network connection configured to:
obtain a manifest file for the selected content, the manifest file comprising URLs for a plurality of versions of the selected content; and
obtain a first version of the plurality of versions of the selected content, wherein the first version is obtained based on the A/V device information, and wherein the first version is specifically supported by the A/V device and is not supported by the local display;

wherein the HDMI connection is further configured to provide the obtained format of the selected content to the A/V device.

10. The client device of claim 9 wherein the network interface is a Wi-Fi interface and the network connection is a Wi-Fi connection.

11. The client device of claim 9 wherein the network interface is an ethernet interface and the network connection is an ethernet connection.

12. The client device of claim 9 wherein each version of the plurality of versions of the selected content has a different bitrate.

13. The client device of claim 9 wherein:
the HDMI connection is further configured to obtain from a second A/V device, second A/V device information indicative of one or more resolutions supported by the second A/V device, at least one resolution supported by the second A/V device not supported by the first A/V device; and
the network connection is configured to obtain a second version of the plurality of versions of the selected content, wherein the second version is different than the first version and is obtained based on the second A/V device information.

14. The client device of claim 9 wherein the first version of the selected content is obtained via HTTP Live Streaming.

15. The client device of claim 9 wherein the first version of the selected content is composed of a plurality of fixed duration segments.

16. The client device of claim 15 wherein the client device obtains different versions of the selected content for different segments of the selected content.
