Technical Field
The utility model relates to a codec technical field, more specifically says that it relates to an 8k codec.
Background
A codec refers to a device or program capable of transforming a signal or a data stream, the transformation including both an operation of encoding (usually for transmission, storage or encryption) or extracting a signal or a data stream into an encoded stream and an operation of recovering a form suitable for observation or operation from the encoded stream for observation or processing, the codec being composed of a source encoder, a video composite encoder, a transmission buffer, a transmission encoder, and an encoding control section. The image signal of the originating terminal is a composite television signal (analog signal) provided by a camera, a luminance (gray scale) signal and two chrominance signals are separated through digital video conversion, three signals are subjected to A/D conversion to convert the analog signal into a digital signal, each pixel point is 8 bits, the digitized signal is subjected to preprocessing to filter noise in the signal, the noise enters a CIF format conversion circuit to become a CIF standard format, and then the signal enters an information source encoder to perform image compression encoding. The purpose of the preprocessing is to eliminate background noise in the signal, thereby being beneficial to improving the definition of the image, and certainly, the preprocessing can also solve the crosstalk between the luminance signal and the chrominance signal and reduce the effect of folding interference. Codecs are often used in video conferencing and streaming media applications, and are often used mainly in the broadcast and television industry as front-end applications.
Currently, the mainstream 8K codec in the market has single function, and is easy to cause blockage and screen splash in a complex environment. The current 8K encoder has the problems of high hardware complexity, large size, large heat productivity, low compression efficiency and the like, and the quality and the efficiency of the encoder determine the efficiency of video encoding to a great extent. To address this problem, an 8k codec is now designed.
SUMMERY OF THE UTILITY MODEL
