摘要
实现可传动态图像与声音的多媒体手机的关键技术,除了图像与语音的编码压缩、同步和复用外,还要解决可视通话与普通通话切换的问题。给出了一种以MC9328MXL主处理器和AK4640语音编解码器为主要器件的硬件解决方案及主要框图,并对这一方案存在的不足提出了改进意见。
The key technologies of multimedia handset transmitting voice and dynamic images should not only carry out code compression, synchronization and multiplexing of image and voice, but process the shift between video and voice communication. This article presents a hardware solution based on MC9328MXL processor and AK4640 voice CODEC. It also points out improved suggestions for the shortcomings in this solution.
