Multimedia Data Acquisition
The fundamentals of the audio and image data were presented in Chapters 2 and 3. For multimedia data analysis, we need to store the multimedia data and process it. The audio sources (e.g., microphones) or the image sources (e.g., camera) generally produce continuous-time analog signals (e.g., output voltage). In order to store audio or video data into a computer, we must sample and digitize the data. This will convert the continuous data into a stream of numbers. In this chapter, we primarily focus on the principles of sampling and digitization of multimedia data.
