20200092562 | SYSTEMS AND METHODS FOR ADAPTIVELY ENCODING VIDEO STREAM - The disclosed technology relates to adaptively encoding a video stream based on viewer engagement, content schedule and/or content characteristics. A system routes a video stream from a signal extractor to a first virtual encoder. The first virtual encoder is instantiated on a cloud platform and provides a first video output at a first bitrate. A second virtual encoder is instantiated on the cloud platform in response to a change in viewer count. The system routes the video stream from the signal extractor to the second virtual encoder. The second virtual encoder provides a second video output at a second bitrate. The second bitrate is different from the first bitrate. | 2020-03-19 |
20200092563 | ENCODER, DECODER, ENCODING METHOD, AND DECODING METHOD - An encoder includes circuitry and a memory connected to the circuitry. In operation, the circuitry: generates a plurality of predicted values of a pixel in a current picture to be encoded, using a plurality of reference pixels in the current picture, and enables or disables a process of determining a predicted value of the pixel on a block-by-block basis based on availability of at least one reference pixel among the plurality of reference pixels by filtering the plurality of predicted values based on a position of the pixel. | 2020-03-19 |
20200092564 | SYSTEM AND METHOD FOR FOVEATED COMPRESSION OF IMAGE FRAMES IN A SYSTEM ON A CHIP - An exemplary method for intelligent compression uses a foveated-compression approach. First, the location of a fixation point within an image frame is determined. Next, the image frame is sectored into two or more sectors such that one of the two or more sectors is designated as a fixation sector and the remaining sectors are designated as foveation sectors. A sector may be defined by one or more tiles within the image frame. The fixation sector includes the particular tile that contains the fixation point and is compressed according to a lossless compression algorithm. The foveation sectors are compressed according to lossy compression algorithms. As the locations of foveation sectors increase in angular distance from the location of the fixation sector, a compression factor may be increased. | 2020-03-19 |
20200092565 | MAKING OBJECT-LEVEL PREDICTIONS OF THE FUTURE STATE OF A PHYSICAL SYSTEM - A system implemented by one or more computers comprises a visual encoder component configured to receive as input data representing a sequence of image frames, in particular representing objects in a scene of the sequence, and to output a sequence of corresponding state codes, each state code comprising vectors, one for each of the objects. Each vector represents a respective position and velocity of its corresponding object. The system also comprises a dynamic predictor component configured to take as input a sequence of state codes, for example from the visual encoder, and predict a state code for a next unobserved frame. The system further comprises a state decoder component configured to convert the predicted state code, to a state, the state comprising a respective position and velocity vector for each object in the scene. This state may represent a predicted position and velocity vector for each of the objects. | 2020-03-19 |
20200092566 | METHOD AND SYSTEM FOR DETERMINING A FLOW RATE OF A FUGITIVE FLUID PLUME - A method of determining a flow rate of a predetermined emissive substance involves: (a) generating a timed sequence of images; (b) partitioning a first image of the timed sequence into a plurality of blocks of pixels; (c) selecting from the plurality of blocks a selected block having calculated therefrom a first set of Discrete Cosine Transform (DCT) coefficients; (d) determining that the first set meets a condition associated with a predetermined threshold such that the first block represents an intensity pattern of the predetermined emissive substance at a first time; (e) selecting a corresponding block of a second image of the timed sequence, the corresponding block having DCT coefficients correlated to the first set such that the corresponding block represents the intensity pattern at a second time different from the first time; (f) determining a velocity associated with the selected block; and (g) determining the flow rate in response to the velocity. | 2020-03-19 |
