摘要： The present invention relates to converting media bitstreams across different networks in a media gateway without any algorithmic delay, and reduces the computation load within the transmission in the situation where the bandwidth of the outgoing network varies dynamically. A first embodiment of the present invention provides an apparatus and a method for a Reduced-Algorithmic-Delay Media Stream Unit Conversion module which is a light weight Simple Pass-Through operation. A second embodiment of the present invention provides an apparatus and a method for a Reduced-Algorithmic-Delay Video Rate Conversion. An alternative embodiment provides an apparatus and a method for a Smart Pass-Through Operation which involves switching between the Simple Pass-Through and the Rate Converter. The methods and apparatuses provided by the first and second embodiment can be used as a stand alone system, or as part of the module of the alternative embodiment.
摘要翻译：本发明涉及在媒体网关中的不同网络上转换媒体比特流而没有任何算法延迟，并且在出局网络的带宽动态变化的情况下减少传输内的计算负荷。本发明的第一实施例提供了一种重量轻的简单通过操作的减速算法延迟媒体流单元转换模块的装置和方法。本发明的第二实施例提供了一种用于减少算法延迟视频速率转换的装置和方法。替代实施例提供了一种智能直通操作的装置和方法，其涉及在简单通过和速率转换器之间切换。由第一和第二实施例提供的方法和装置可以用作独立系统，或者作为替代实施例的模块的一部分。
