Limiting the speed of data sent by a data originator (a client computer or a server computer) is much more efficient than limiting the speed in an intermediate network device between client and server because while in the first case usually no network packets are lost, in the second case network packets can be lost / discarded whenever ingoing data speed overcomes the bandwidth limit or the ...
The range of the human voice extends from 100 Hz to 17 kHz [2] but traditional, voiceband or narrowband telephone calls limit audio frequencies to the range of 300 Hz to 3.4 kHz. Wideband audio relaxes the bandwidth limitation and transmits in the audio frequency range of 50 Hz to 7 kHz.
High Speed Downlink Packet Access (HSDPA) is an enhanced 3G (third-generation) mobile communications protocol in the High-Speed Packet Access (HSPA) family. HSDPA is also known as 3.5G and 3G+ . It allows networks based on the Universal Mobile Telecommunications System (UMTS) to have higher data speeds and capacity.
Latency refers to a short period of delay (usually measured in milliseconds) between when an audio signal enters a system, and when it emerges.Potential contributors to latency in an audio system include analog-to-digital conversion, buffering, digital signal processing, transmission time, digital-to-analog conversion, and the speed of sound in the transmission medium.
External AV-sync errors can occur if a microphone is placed far away from the sound source, the audio will be out of sync because the speed of sound is much lower than the speed of light. If the sound source is 340 meters from the microphone, then the sound arrives approximately 1 second later than the light. The AV-sync delay increases with ...
Verified for iOS 9.3 and later. 1. Double press the Home button or swipe up and hold. 2. Swipe up on the image of the app. 3. Re-launch the app and attempt to reproduce the issue.
HDMI specifically requires the device implement the Enhanced Display Data Channel (E-DDC), which is used by the HDMI source device to read the E-EDID data from the HDMI sink device to learn what audio/video formats it can take. [5]: §§8.1, CEC-1.2–CEC-1.3 HDMI requires that the E-DDC implement I 2 C standard mode speed (100 kbit/s) and ...
With EDGE, the RLC interface could operate in either acknowledged mode, or unacknowledged mode. In unacknowledged mode, there is no retransmission of missing data blocks, so a single corrupt block would cause an entire upper-layer IP packet to be lost. With non-persistent mode, an RLC data block may be retransmitted if it is less than a certain ...
