Abstract
An embodiment is a method and apparatus to process video frames. An entropy decoder performs entropy decoding on a bitstream of a video frame extracted from a network frame. The entropy decoder generates discrete cosine transform (DCT) coefficients representing a picture block in the video frame. The entropy decoder is configured for serial operations. A graphics processing unit (GPU) performs image decoding using the DCT coefficients. The GPU is configured for parallel operations.One disclosed feature of the embodiments is a technique to decode a video frame. A GPU performs image encoding of a video frame computing quantized DCT coefficients representing a picture block in the video frame. The GPU is configured for parallel operations. An entropy encoder performs entropy encoding on the quantized DCT coefficients. The entropy encoder is configured for serial operations.
