Abstract
In an apparatus for transcoding a compressed video, a generator simulates constraints of a network and constraints of a user device. A classifier is coupled to receive an input compressed video and the constraints. The classifier generates content information from features of the input compressed video. A manager produces a plurality of conversions modes dependent the constraints and content information, and a transcoder produces output compressed videos, one for each of the plurality conversion modes.
Claims8
An apparatus for transcoding a compressed video, comprising:
- a generator configured to simulate a plurality of constraints of a network and constraints of a user device;
- a classifier, coupled to receive an input compressed video and the plurality of constraints, configured to generate content information from features of the input compressed video;
- a manager, coupled to the classifier and the generator, configured to produce a plurality of conversions modes dependent the constraints and content information;
- and
- a transcoder, coupled to the classifier and the manger, configured to produce a plurality of output compressed videos, one for each of the plurality conversion modes.
A method for transcoding a compressed video, comprising the steps of:
- simulating a plurality of constraints of a network and constraints of a user device;
- generating content information from features of an input compressed video;
- producing a plurality of conversions modes dependent the constraints and content information;
- producing an output compressed video for each of the plurality conversion modes.
