What does Internet Protocol TV (IPTV), which implements broadcast services on IP networks, have to do with smart TV? According to the definition of IPTV given by the International Telecommunication Union (ITU), IPTV is defined as “multimedia services such as television/video/audio/text/graphics/data delivered over IP based networks managed to provide the required level of QoS/QoE (quality of service/quality of experience), security, interactivity and reliability.” On the basis of this definition, the services that will implement smart TV are expected to be handled the same way IPTV services are handled. The latter standpoint tries to diversify program delivery services by combining broadcast services and communication services, for example, Hybridcast, a broadcast service that started in Japan in September 2013. It concerns the addition of functions to TV receivers by installing a variety of applications in them, similar to the way smartphones are enhanced mobile phones.
In other words, the former standpoint is mainly held by TV receiver manufacturers who sell their own smart TVs. It is instinctively understood that smart TV is an enhanced version of what we call TV, but the emphasis depends on the standpoint as to whether TV receivers themselves should be enhanced or whether TV broadcast services should be enhanced. Introduction Smart TV (television) has recently become a popular topic with electrical appliance retailers and in the media such as newspapers and magazines.
