Integrated internet protocol television settop box

The present invention relates to an integrated IPTV set-top box, in particular, a virtual keyboard is built into the IPTV set-top box, and various peripherals can be wired and wirelessly connected, and a DVD player is built in so that digital broadcasting can be viewed using the IPTV set-top box. And of course, it's all about integrated IPTV set-top boxes that make real-time Internet easier and DVDs easier to watch.

Currently, various digital broadcasting services, such as terrestrial broadcasting, satellite broadcasting, and cable broadcasting, are provided, and a set-top box dedicated to receiving digital broadcasting is required to view them.

Existing set-top box occupies its position with terrestrial set-top receiving terrestrial broadcasting and satellite set-top receiving satellite broadcasting with its own functions, and provides two-way service to these terrestrial and satellite broadcasting with the development of IP network. For this reason, terrestrial set-tops combined with IP, so-called IP / terrestrial set-tops, and IP-coupled satellite set-tops called IP / satellite set-tops have emerged. In addition, with the development of IP networks, IP set-tops receiving IPTV broadcasts are also emerging.

In general, Internet Protocol Television (IPTV) is a digital convergence form in which broadcasting and communication are converged with the reception of broadcast signals transmitted from a program provider (PP) or terrestrial, cable, and satellite. In addition, a TV set (TV) connected to an IP Set Top Box (STB) is used to provide Internet Contents On Demand (ICOD) services such as TV Internet content and video content (T-VOD) through an IP network. to provide.

IPTV services are called IPTV in the US, ADSL TV in Europe, and broadband broadcasting in Japan.

The main components of the IPTV service system include an IPTV Headend System, an IP Backbone Network, an IP Backbone, an Access Network (eg xDSL, HFC, FTTC, FTTH), and a Subscriber Terminal (STB, TV).

IPTV service is a broadband broadband service that provides two-way TV contents in the form of convergence of communication and broadcasting according to the digital convergence of the broadcast provider of the program provider (PP) and the content provider (CP) of the Internet market. A TV connected to an IP set-top box (STB) via an internet network receives Internet multimedia contents including audio, video, and packet data, and is interactively used by using a bidirectional communication channel as a return path concept. Use TV service.

Hereinafter, an IPTV service according to the prior art will be described with reference to the accompanying drawings.
