Audio Video Coding refers to the process of compressing and encoding audio and video data to reduce file size while maintaining quality. This is essential for efficient storage and transmission, especially in streaming services and digital media. Common coding formats include MP3 for audio and H.264 for video. The coding process involves algorithms that analyze the data and remove redundant information. This allows for faster downloads and less bandwidth usage, making it easier for users to access content on devices like smartphones, tablets, and computers. Overall, Audio Video Coding plays a crucial role in modern multimedia experiences.
