The Code In this lab you will implement a streaming video server and client that communicate using the Real-Time Streaming Protocol (RTSP) and send data using the Real-Time Transfer Protocol (RTP ). your task is to implement the RTSP protocol in the client and implement the RTP packetization in the server. We will provide you code that implements the RTSP protoco

the sampling frequency is the sampling period or the sampling time, which is the time interval between the samples. The popular speaking sampling frequency is refers to the computer each second gathers how many sound samples, is describes the sound file the quality, the tone, the measurement sound card, the sound document standard. In today's mainstream acquisition card, sampling frequency is generally divided into 22.05KHz, 44.1KHz, 48KHz three levels, 22.05KHZ can only achieve FM broadcast so
