摘要

本文介绍了一种数字电视机用全双工免提可视电话附加装置的原型。它由数码相机和麦克风阵列组成，通过高清多媒体接口连接到电视机上。该系统可通过3G调制解调器进行扩展，可以作为3G网络的视频电话在独立模式下工作。该附加组件提供:免提视频通信，通过电视扬声器提供出色的音质，并同时观看电视广播。当与远程用户通信处于活动状态时，嵌入式音频处理引擎可以有效地抑制来自电视广播的现有声音。这是可能的麦克风阵列的使用和复杂的语音处理算法在后台。该插件旨在扩展电视机的功能并改善用户体验。

A full-duplex hands-free videophone add-on device for digital television sets

This paper presents a prototype of full-duplex hands-free videophone add-on device for digital television sets. It consists of a digital camera and microphone array which are connected to the TV set through the High-Definition Multimedia Interface. The system is extendable with a 3G modem to become capable of working in a stand-alone mode as a video phone for 3G network. The add-on provides: hands-free video communication, excellent sound quality via TV loudspeakers and simultaneous watch of the TV broadcast. While the communication with remote user is active, the existing sound from the TV broadcast is efficiently suppressed with the embedded audio processing engine. This is possible with microphone array usage and sophisticated voice processing algorithms in the background. This add-on aims to extend functionality of TV sets and improve user experience.
