Abstract
A method, performed by a computer device, may include receiving a request for a video asset from a user device, wherein the request includes information identifying a device type associated with the user device and a processor load associated with the user device. The method may further include determining a bandwidth capacity associated with a connection to the user device; selecting a codec and a quality level for the requested video asset based on the device type, the processor load, and the determined bandwidth capacity; identifying a Uniform Resource Identifier associated with the selected codec and quality level for the requested video asset; and providing the identified Uniform Resource Identifier to the user device.
Claims18
A method, performed by a computer device, the method comprising:
- receiving, by the computer device via a network, a request for a video asset from a user device, wherein the request includes information identifying a device type associated with the user device and a processor load associated with the user device, wherein the computer device includes a database that stores Uniform Resource Identifiers for particular video assets;
- obtaining, by the computer device, information identifying a last viewed position for the requested video asset for a user account associated with the user device;
- identifying, by the computer device, a segment of the requested video asset based on the obtained information identifying the last viewed position for the requested video asset;
- determining, by the computer device, a bandwidth capacity associated with a connection to the user device;
- selecting, by the computer device, a codec and a quality level for the requested video asset based on the device type, the processor load, and the determined bandwidth capacity;
- identifying, by the computer device, a Uniform Resource Identifier associated with the selected codec and quality level for the requested video asset using the database, wherein identifying the Uniform Resource Identifier associated with the selected codec and quality level for the requested video asset includes:
- identifying a segment Uniform Resource Identifier associated with the selected codec and quality level for the identified segment of the requested video asset;
- providing, by the computer device via the network, the identified segment Uniform Resource Identifier to the user device;
- receiving, by the computer device via the network, a request for a next segment of the requested video asset from the user device, wherein the request for the next segment includes
- processor load information that indicates that the processor load associated with the user device has changed;
- selecting, by the computer device, a different codec for the requested video asset, based on the processor load information that indicates that the processor load associated with the user device has changed;
- identifying, by the computer device, a different Uniform Resource Identifier associated with the different codec for the requested video asset using the database;
- and
- providing, by the computer device via the network, the identified different Uniform Resource Identifier to the user device.
