The Video Buffering Verifier (VBV) is a theoretical MPEG video buffer model, used to ensure that an encoded video stream can be correctly buffered, and played back at the decoder device. By definition, the VBV shall not overflow nor underflow when its input is a compliant stream, (except in the case of low_delay).
They can result from improper clock sources [3] and buffer size. Also, clicks can be caused by electric devices near the computer or by faulty audio or mains cables. [4] In sample recording, digital clicks occur when the signal levels of two adjacent audio sections do not match. The abrupt change in gain can be perceived as a click. [5]
Pro Tools was developed by UC Berkeley graduates Evan Brooks, who majored in electrical engineering and computer science, and Peter Gotcher. [17]In 1983, the two friends, sharing an interest in music and electronic and software engineering, decided to study the memory mapping of the newly released E-mu Drumulator drum machine to create EPROM sound replacement chips.
The simplest guard against such problems is to increase the size of the buffer—if an incoming data stream needs to be read at 1 bit per second, a buffer of 10 bits would allow the connection to be blocked for up to 10 seconds before failing, whereas one of 60 bits would allow a blockage of up to a minute. However, this requires more memory to ...
This acknowledgement announces that the receiver is ready to receive n frames, beginning with the number specified. Both the sender and receiver maintain what is called a window. The size of the window is less than or equal to the buffer size. Sliding window flow control has far better performance than stop-and-wait flow control.
A bloated buffer has an effect only when this buffer is actually used. In other words, oversized buffers have a damaging effect only when the link they buffer becomes a bottleneck. The size of the buffer serving a bottleneck can be measured using the ping utility provided by most operating systems. First, the other host should be pinged ...

Visualization of a software buffer overflow. Data is written into A, but is too large to fit within A, so it overflows into B.. In programming and information security, a buffer overflow or buffer overrun is an anomaly whereby a program writes data to a buffer beyond the buffer's allocated memory, overwriting adjacent memory locations.
