HC-IPTV, namely Interactive Network Television, can be watched by directly connecting broadband set-top boxes to TV sets. HC-IPTV is a new technology that uses broadband cable television networks and integrates various technologies such as the Internet, multimedia, and communications. It provides families with multiple interactive services including digital television. Users can enjoy IPTV services at home through network set-top boxes and ordinary televisions. It can well adapt to the current rapid development trend of the network and make full and effective use of network resources. HC-IPTV is different from both traditional analog cable TV and classic digital TV. Because both traditional and classic digital TVs have characteristics such as frequency division system, timing, and one-way broadcasting; although classic digital TV has many technical innovations compared to analog TV, it only changes the form of the signal without touching the dissemination method of media content.
