摘要： The disclosure is directed to techniques for region-of-interest (ROI) processing for video telephone (VT) applications. According to the disclosed techniques, a recipient device defines ROI information for video information transmitted by a sender device, i.e., far-end video information. The recipient device transmits the ROI information to the sender device. Using the ROI information transmitted by the recipient device, the sender device applies preferential encoding to an ROI within a video scene. In this manner, the recipient device is able to remotely control ROI encoding of far-end video information by the sender device.

摘要： Techniques are presented herein to provide tandem-free operation between two wireless terminals through two otherwise incompatible wireless networks. Specifically, embodiments provide tandem-free operation between a wireless terminal communicating through a continuous transmission (CTX) wireless channel to a wireless terminal communicating through a discontinuous transmission (DTX) wireless channel. In a first aspect, inactive speech frames are translated between DTX and CTX formats. In a second aspect, each wireless terminal includes an active speech decoder that is compatible with the active speech encoder on the opposite end of the mobile-to-mobile connection.

摘要： Natural-quality synthetic noise will replace background acoustic noise during speech gaps and will achieve a better representation of the excitation signal in a noise-synthesis model by classifying the type of acoustic environment noise into one or more of a plurality of noise classes. The noise class information is used to synthesize background noise that sounds similar to the actual background noise during speech transmission. In some embodiments, the noise class information is derived by the transmitter and transmitted to the receiver which selects corresponding excitation vectors and filters them using a synthesis filter to construct the synthetic noise. In other embodiments, the receiver itself classifies the background noise present in hangover frames and uses the class information as before to generate the synthetic noise. The improvement in the quality of synthesized noise during speech gaps helps to preserve noise continuity between talk spurts and speech pauses, and enhances the perceived quality of a conversation.
摘要翻译：自然质量合成噪声将代替语音间隙期间的背景声学噪声，并且将通过将声学环境噪声的类型分类为多个噪声等级中的一个或多个来实现噪声合成模型中的激励信号的更好表示。噪声等级信息用于合成在语音传输期间听起来类似于实际背景噪声的背景噪声。在一些实施例中，噪声等级信息由发射机导出，并发射到接收机，接收机选择对应的激励矢量，并使用合成滤波器对它们进行滤波以构成合成噪声。在其他实施例中，接收机本身对存在于宿醉帧中的背景噪声进行分类，并像以前一样使用类信息以产生合成噪声。语音间隙中合成噪声质量的提高有助于保持语音冲突和语音暂停之间的噪声连续性，并提高对话的感知质量。
