The HCV300 high definition audio and video codec is a program or device that can compress or decompress digital video. Usually this compression is lossy data compression. The design of the HCV300 high-definition audio and video codec is usually standardized, that is, there are published documents to accurately specify how to proceed. With the rapid development of high technology, in order to meet the needs of more fields, HD video codecs have emerged.
The HCV300 high-definition audio and video codec basically does not consider how the signal is generated, but directly samples and encodes the input analog signal, and then transmits the quantized sample to the terminal, where the original signal is recombined to be close to the original signal. Degree. Therefore, the waveform coding method is an encoding method capable of faithfully expressing a waveform. Since such encoders usually process speech signals as general waveform signals, the HCV300 high-definition audio and video codec has the characteristics of strong adaptability, good voice quality, strong anti-noise and error resistance. Its biggest drawback is that it uses a lot of bandwidth compared to other codecs, and when the waveform codec is used for low bandwidth, the voice quality drops very quickly.
So what are the precautions when using the HCV300 HD audio and video codec ?
1. When using the video codec manufacturer's decoder, please do not put any heavy objects on the video codec to avoid deformation of the outer casing under heavy pressure, resulting in crushing damage of the internal parts of the decoder. At the same time, video codec manufacturers also remind everyone, do not let dust, fine particles, liquids enter the codec inside the gap of the chassis.
2. In order to extend the service life and quality of the video codec, you should regularly use a soft brush to remove dust from the codec's circuit board, connectors, chassis fan, chassis, etc. It is important to note that the body is being used. Please turn off the power of the codec and unplug the power before cleaning.
3. Because the video codec manufacturer adopts the precise design structure when producing the codec, when the codec is abnormal, please do not disassemble, repair or replace the device by yourself. You should go to the professional maintenance office. Check and repair.
4. The codec produced by the video codec manufacturer belongs to the precision electronic products, so it should be noted to maintain a good environment, not too dry and humid, not too high temperature, avoid large temperature difference, avoid close to heat source and be long-term by sunlight. Directly expose to the sun and avoid using it in a dusty and dusty environment.
