Abstract

A number of approaches for transcoding media is described, which allow various users to control one or more aspects of transcoding (e.g. bit rate, resolution) when delivering media content to a client device from a network edge server or other location. The client device is provided with an interface that allows the user to increase or decrease the resolution, bit rate or other settings of the media content. Upon receiving a request from the user, the system transcodes the media content in accordance with the request and dynamically delivers the transcoded media content to the user's device. The system also enables content publishers and network operators to impose restrictions (e.g. minimum and maximum values for various settings) on user control.

First claim

What is claimed is:

1. A computer implemented method, comprising:
receiving, in an interface associated with a service provider, restrictions from different entities to a range of bit rates and resolutions for distributing media;
storing a profile associated with the restrictions;
providing access to the profile using an application programming interface (API);
providing the media associated with the restrictions in the profile based in part on a request through the API;
receiving an adjustment to a user-adjustable quality setting for the media; and
transcoding the media from a source format into at least one different format based at least in part on the adjustment to the user-adjustable quality setting being within the restrictions in the profile to produce at least one transcoded version of the media.

2. The computer implemented method of claim 1 , further comprising:
verifying that the user-adjustable quality setting complies with at least one first restriction specified by a content publisher and at least one second restriction specified by a network operator, the content publisher and the network operator being the different entities.

3. The computer implemented method of claim 1 , wherein the restrictions comprise a minimum bit rate for the range of bit rates, a maximum bit rate for the range of bit rates, and a resolution for the transcoding of the media.

4. The computer implemented method of claim 1 , further comprising:
enabling one or more graphical user interfaces (GUIs) to receive at least one of the restrictions and the user-adjustable quality setting.

5. The computer implemented method of claim 1 , further comprising:
accessing the profile associated with the restrictions;
determining at least one of a bit rate for the media or a resolution of the media based at least in part on time-of-day or network traffic congestion associated with a network over which the media is to be provided to the client device;
determining that the bit rate is within the range of bit rates from the restrictions or that the resolution is one of the resolutions for distributing the media from the restrictions; and
transcoding the media by modifying the bit rate or the resolution of the media.

6. The computer implemented method of claim 1 , further comprising:
storing a default profile associated with an operating system of a client device; and
modifying the default profile using the restrictions to generate the profile associated with the restrictions.

7. A system, comprising:
at least one processor; and
memory including instructions that, when executed, cause the system to:
store a profile of restrictions received through an interface for at least one of a range of bit rates and resolutions for distributing media from a service provider;
enable access to the profile using an application programming interface (API);
receive an adjustment to a user-adjustable quality setting for the media;
determine that the adjustment is within the restrictions in the profile based in part on a request through the API; and
transcode the media from a source format into at least one different format based to produce at least one transcoded version of the media.

8. The system of claim 7 , wherein the user-adjustable quality setting for the media is generated by at least one of: a browser on a client device; an application executing on the client device, or an operating system of the client device.

9. The system of claim 7 , wherein a network operator is enabled to modify at least one of the user-adjustable quality setting to adjust a quality of service associated with the network.

10. The system of claim 7 , wherein the restrictions comprise a minimum bit rate for the range of bit rates, a maximum bit rate for the range of bit rates, and a resolution for the transcoding of the media.

11. The system of claim 7 , wherein the instructions further cause the system to:
enable one or more graphical user interfaces (GUIs) to receive at least one of the restrictions and the user-adjustable quality setting.

12. The system of claim 7 , wherein the instructions further cause the system to:
access the profile associated with the restrictions;
determine at least one of a bit rate for the media or a resolution of the media based at least in part on time-of-day or network traffic congestion associated with a network over which the media is to be provided to the client device;
determine that the bit rate is within the range of bit rates from the restrictions or that the resolution is one of the resolutions for distributing the media from the restrictions; and
transcode the media by modifying the bit rate or the resolution of the media.

13. The system of claim 7 , wherein the instructions further cause the system to:
store a default profile associated with an operating system of a client device; and
modify the default profile using the restrictions to generate the profile associated with the restrictions.

14. The system of claim 7 , wherein the instructions further cause the system to:
determine an attribute associated with the media or a location of the media received from a content publisher;
select a default profile to be applied to the media based in part on the attribute or the location; and
enable modification of the default profile using the restrictions to generate the profile associated with the restrictions.

15. The system of claim 7 , wherein the instructions further cause the system to:
receive, in the interface, at least one of a first restriction specified by a content publisher and a second restriction specified by a network operator;
verify that the user-adjustable quality setting for the media, defined by a content publisher, complies with at least one of the first restriction and the second restriction; and
enable the adjustment to the user-adjustable quality setting for the media.

16. A non-transitory computer readable storage medium storing instructions executable by one or more processors to perform steps comprising:
storing a profile of restrictions received through an interface for at least one of a range of bit rates and resolutions for distributing media from a service provider;
enabling access to the profile using an application programming interface (API);
receiving an adjustment to a user-adjustable quality setting for the media;
determining that the adjustment is within the restrictions in the profile based in part on a request through the API; and
transcoding the media from a source format into at least one different format based to produce at least one transcoded version of the media.

17. The non-transitory computer readable storage medium of claim 16 , wherein the user-adjustable quality setting for the media is generated by at least one of: a browser on a client device; an application executing on the client device, or an operating system of the client device.

18. The non-transitory computer readable storage medium of claim 16 , wherein a network operator is enabled to modify at least one of the user-adjustable quality setting to adjust a quality of service associated with the network.

19. The non-transitory computer readable storage medium of claim 16 , wherein the restrictions comprise a minimum bit rate for the range of bit rates, a maximum bit rate for the range of bit rates, and a resolution for the transcoding of the media.

20. The non-transitory computer readable storage medium of claim 16 , wherein the instructions executable by the one or more processors further
