10 results about "Uncompressed video" patented technology

Uncompressed video is digital video that either has never been compressed or was generated by decompressing previously compressed digital video. It is commonly used by video cameras, video monitors, video recording devices (including general purpose computers), and in video processors that perform functions such as image resizing, image rotation, deinterlacing, and text and graphics overlay. It is conveyed over various types of baseband digital video interfaces, such as HDMI, DVI, DisplayPort and SDI. Standards also exist for carriage of uncompressed video over computer networks.

Systems, methods, and apparatuses for video processing

Systems, methods, and apparatuses are described for processing video. Encoded video data may be determined from uncompressed video data. A chrominance component for a portion of the encoded video data may be determined that references another portion of the encoded video data. A luma component of the portion of the encoded video data may be determined to correspond with the luma component of the corresponding portion of the uncompressed video data.

Machine learning model-based video compression

A system processing hardware executes a machine learning (ML) model-based video compression encoder to receive uncompressed video content and corresponding motion compensated video content, compare the uncompressed and motion compensated video content to identify an image space residual, transform the image space residual to a latent space representation of the uncompressed video content, and transform, using a trained image compression ML model, the motion compensated video content to a latent space representation of the motion compensated video content. The ML model-based video compression encoder further encodes the latent space representation of the image space residual to produce an encoded latent residual, encodes, using the trained image compression ML model, the latent space representation of the motion compensated video content to produce an encoded latent video content, and generates, using the encoded latent residual and the encoded latent video content, a compressed video content corresponding to the uncompressed video content.

Online video game service with split clients

A method for an online video game or application service system includes running a video game or application on an application host server at a data center, an uncompressed video stream being produced therefrom. The uncompressed video stream is encoded into compressed video stream, which is then transmitted over the Internet to an output client device of a user. The output client device decompresses the compressed video stream and displays live video on a screen. User control input transmitted from an input client device is delivered to the application host server. The user control input includes game or application commands. The input client device is associated with the user and is separate from the output client device. Responsive to receiving the game or application commands, the application host server generates a new uncompressed video stream.

Decoding method, encoding method and related devices

A method of decoding compressed video or image data, or encoding uncompressed video or image data, using an 8-bit primary transform kernel matrix. The method can include determining whether to use a first transform kernel matrix having a first size type or a second transform kernel matrix having a second size type that is smaller than the first size type. When the result of the determination is to use the first transform kernel matrix, an 8-bit primary transform kernel matrix having a size of 64 points or more is used to encode or decode a target file. Otherwise, the method can include extracting the second transform kernel matrix of the second size type from the first transform matrix, and using the extracted second transform kernel matrix to encode or decode the target file.

Method for analyzing the change in a video stream for limited-rate and low-latency video coding, and associated device

A method for analysing the change between two frames of an uncompressed video stream, including estimating a shift and statistical deviation between all or part of the frames in at least one direction, and using the one or more computed shifts and statistical deviations to detect a significant change between the frames. A method for coding an uncompressed video stream, wherein information relating to a significant change is used to modify the uncompressed video stream or coding parameters of the uncompressed video stream, in order to avoid peaks in rate. A device implementing either of the methods, to a complete transmitting system, to a computer program product comprising program instructions allowing the steps of the methods to be executed, and to a recording medium comprising the computer program product.
