This time period is called a beacon period (BP). At the beginning of each BP, there is a beacon generation window consisting of + slots each of length aSlotTime. Each station calculates a random delay uniformly distributed in [,] and is scheduled to transmit a beacon when the delay timer expires. If a beacon arrives before the random delay ...
Analog delay lines are applied in many types of signal processing circuits; for example the PAL television standard uses an analog delay line to store an entire video scanline. Acoustic and electromechanical delay lines are used to provide a " reverberation " effect in musical instrument amplifiers, or to simulate an echo.
The AV-sync delay is static but can vary with the individual clip. Video editing effects can delay video causing it to lag the audio. Transmission (broadcasting), reception and playback that can get introduce AV-sync errors. A video camera with built-in microphones or line-in may not delay sound and video paths by the same amount.
A bucket brigade or bucket-brigade device (BBD) is a discrete-time analogue delay line, [1] developed in 1969 by F. Sangster and K. Teer of the Philips Research Labs in the Netherlands. It consists of a series of capacitance sections C 0 to C n. The stored analogue signal is moved along the line of capacitors, one step at each clock cycle.
UPDATED: YouTube users in multiple regions around the world encountered issues in playing videos on the site Wednesday for more than an hour. Extended outages are rare for YouTube, which boasts ...
The group delay and phase delay properties of a linear time-invariant (LTI) system are functions of frequency, giving the time from when a frequency component of a time varying physical quantity—for example a voltage signal—appears at the LTI system input, to the time when a copy of that same frequency component—perhaps of a different physical phenomenon—appears at the LTI system output.
In distributed computing, the problem takes on more complexity because a global time is not easily known. The most used clock synchronization solution on the Internet is the Network Time Protocol (NTP) which is a layered client-server architecture based on User Datagram Protocol (UDP) message passing.
