Adaptive coding, transmission and efficient display of multimedia (acted)

Abstract

Embodiments of the invention receive videos and feedback data associated with the videos from a client device and adaptively encode the videos based on the feedback data. The encoded videos are suitable to be transmitted over a network and displayed on the client device. Embodiments of an encoding server adaptively changes resolution of a video on the fly or scale the video quality up or down based on the factors described by the feedback data, including network condition for transmitting the encoded video, network delay, encoder and decoder processing capacity and feedback from viewers of the decoded video. Furthermore, the encoding server adaptively encodes the video based on a combination of various factors described by the feedback data.

What is claimed is: 
     
         1 . A computer-implemented method comprising:
 receiving, by an encoding server comprising one or more processors and memory, an input video;   generating a plurality of encoded bitstreams from the input video using a plurality of encoding schemes, each encoded bitstream generated by applying a respective encoding scheme of the plurality of encoding schemes to the input video, each of the plurality of encoding schemes including one or more of a color transform or a filtering of the video, and the encoding scheme is associated with one or more of network conditions or capabilities of a client device, the network conditions including bandwidth constraints, the capabilities including video display requirements of the client device;   receiving feedback data;   selecting an encoded bitstream from the plurality of encoded bitstreams having a minimum cost according to a rate-distortion optimization (RDO) method, wherein the cost of a corresponding encoded bitstream is determined based on one or more of
 (i) a distortion due to an encoding associated with the corresponding encoded bitstream, 
 (ii) a data rate for transmitting the corresponding encoded bitstream according to feedback data received, and 
 (iii) the capabilities of a client device; and 
   performing one or more of transmitting the selected encoded bitstream or storing the selected bitstream on a storage device.
