基于HFC有线电视网络的远程居家看护系统

Tele-homecare Model in HFC CATV Networks

采用计算机平台和无计算机平台的设计方法 ,整合国际互联网络资源 ,提出以缆线调制解调器进行视频、声音及生理信号的传送 ,以浏览器为界面进行远程居家看护服务。使用传统有线电视播送方式传送视频及声音 ,配合所提出的生理信号传送电路 。

In the PC-based and non PC-based, conformity internet resource, commercial cable modems could be installed and used for biomedical data, video, and audio transmission. The user interface is a user friendly browser that can support health education using internet resources. The non-PC based version uses analog CATV to transmit video and audio signals via a PAL channel. This version provides an RF modem interface, which inserts biomedical signals into the HFC network. The RF modem puts digitized biomedical signals into the second audio program sub channel, which can be used for second language audio in PAL television broadcasts, then structure integer tele homecare systems.
