用于提供动态比特率编码的设备和方法
摘要：
一种设备、系统和方法，用于根据为无线传递源数据所确定的可用带宽，动态地调节编码器比特率。一种方法检测第一可用带宽，根据可用带宽确定第一编码器比特率，以第一编码器比特率编码信号，检测可用带宽的改变以便有第二可用带宽，根据第二可用带宽确定第二编码器比特率，以及以第二编码器比特率编码信号。以第二编码器比特率编码信号可包括编码信号的后续帧。该方法还实时地无线传递以第一编码器比特率编码的信号，以及实时地无线传递以第二编码器比特率编码的信号。
摘要（英）：

An apparatus, system and method for use in for use in dynamically adjusting an encoder bit rate according to a determined available bandwidth for wirelessly communicating source data. A method detectsa first available bandwidth, determines a first encoder bit rate according to the available bandwidth, encodes a signal at the first encoder bit rate, detects a change in the available bandwidth suchthat there is a second available bandwidth, determines a second encoder bit rate according to the second available bandwidth, and encodes the signal at the second encoder bit rate. Encoding the signal at the second encoder bit rate can include encoding a subsequent frame of the signal. The method can further wirelessly communicate the signal encoded at the first encoder bit rate in real-time andwirelessly communicate the signal encoded at the second encoder bit rate in real-time.
