Abstract
A method for encoding a video signal generally includes enabling multiple encoding passes based on a first profile, generating an encoded bitstream during a first time period by encoding each of a plurality of images in the video signal with the multiple encoding passes in a circuit based on the first profile, disabling the multiple encoding passes based on a second profile and generating the encoded bitstream during a second time period by encoding each of the images using a single encoding pass in the circuit based on the second profile. Each profile may determine one or more resources configured to be applied to the images before generating the encoded bitstream.
Claims20
A method for encoding a video signal, comprising the steps of:
- generating an encoded bitstream during a first time period associated with a first time of day by encoding each of a plurality of images in the video signal with a first encoding profile comprising multiple encoding passes in a circuit;
- and
- generating the encoded bitstream during a second time period associated with a second time of day by encoding each of the images using a second encoding profile comprising a single encoding pass in the circuit, wherein each encoding profile determines one or more resources configured to be applied to the images before generating the encoded bitstream.
An apparatus comprising:
- an interface configured to receive a plurality of images in a video signal;
- and
- an encoder circuit configured to (i) generate an encoded bitstream during a first time period associated with a first time of day by encoding each of the images with a first encoding profile comprising multiple encoding passes and (ii) generate the encoded bitstream during a second time period associated with a second time of day by encoding each of the images using a second encoding profile comprising a single encoding pass, wherein each profile determines one or more resources configured to be applied to the images before generating the encoded bitstream.
