摘要
针对广电的可视电话业务,利用广电网络的特点,提出了一种新的可视电话传输方式。上行数据通过IP网络进行传输,下行数据通过HFC网络以TS流的形式进行传输。通过该传输方式可减少丢包、延时等现象,增大了最大并发用户数量,提高了视频通话质量。
According to Radio and Television video phone service,using the characteristics of radio and television network,a new video telephone transmission mode is proposed in this paper.Uplink data transmission through IP network,while the downlink data transmission through the HFC network in the form of TS.The transmission mode can reduce the packet loss,delay and other phenomena,increase the maximum number of concurrent users,and improve video call quality.
