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.
Quantization matrices in video compression
ActiveUS12666025B2Digital video signal modificationSemiconductor devicesComputer graphics (images)Algorithm
An embodiment includes generating, using a first set of parameters, a first quantization matrix. The first set of parameters includes a set of coefficients of a formula that generates quantization values in the first quantization matrix. An embodiment includes encoding, using the first quantization matrix, a frame in an uncompressed video stream, the encoding generating a compressed video stream corresponding to the uncompressed video stream.
