| 单词 | isochronous |
| 释义 | isochronous From the Greek isos, meaning equal or uniform, and chronos, meaning time. 1. Equal in frequency, or periodicity. Uniform in time, having equal duration, or occurring at precise intervals. Isochronous communications, such as real-time audio and video, are stream-oriented, flowing at a constant and regular pace, with each audio and video element being of equal importance.Therefore, each element (e.g., instant of audio or pixel of color) must be delivered to the receiver in exactly the sequence in which it was presented to the transmitter and with no significant level of either latency (i.e., delay), or jitter (i.e., variation in delay). See also jitter, latency, near-realtime, and store-and-forward. 2. A type of digital circuit in which the device on one end sets the bit rate for its own transmission and the receiving device copies that bit rate when responding, but there is no clock signal on the circuit interface. |
