Interactive set-top box

Abstract

The invention discloses an interactive set-top box which relates to a set-top box invented for solving the problem of adopting a cable form for networking in the prior art. The interactive set-top box provided by the invention takes an LINUX system as an operation platform and includes a protocol stack unit used for embedding an IGRS protocol stack, building a connection unit and applying an IGRS protocol to build connection with the other IGRS devices in an IGRS network. The interactive set-top box provided by the invention not only can be applied to the IGRS network for sharing network resources with other IGRS devices by wireless connection, but also can be connected with a movable memory device for sharing the information resources on the movable memory device.

Description

technical field [0001] The invention relates to a set-top box, in particular to an interactive set-top box. Background technique [0002] The set-top box (Set Top Box, STB) refers to the analog channel extender and analog channel descrambler based on the cable TV network in the early days; The television is an information receiving and processing device of a display terminal. [0003] At present, there are many types of set-top boxes on the market. For example, according to the types of received signals, they can be divided into analog set-top boxes and digital set-top boxes; according to the signal transmission network used, they can be divided into satellite transmission set-top boxes, cable set-top boxes and terrestrial transmission. set top box. Among the above-mentioned set-top boxes, most of the functions are limited to receiving and processing image signals and audio signals, and a few set-top boxes provide limited interactive services, such as: playing advertisemen...

Problems solved by technology

[0005] Among them, the connection method based on the telephone line is the easiest to implement, and the cost is also the lowest. Therefore, most of the existing Internet set-top boxes are based on this connection method, but its disadvantage is that the speed and response are slow, resulting in poor user experience.

[0006] In contrast, these problems do not exist in the Ethernet-based connection method, which can provide interactive applications such as video-on-demand and web surfing through the Internet. However, to realize this connection method, a 100 / 10M Ethernet card needs to be added to the set-top box , which greatly increases the cost of the whole machine. In addition, its application is also limited by whether the Ethernet interface has been deployed in the user's home.

[0007] The cable-based connection method is an ideal connection method conceived by the industry. It can realize fast and convenient interactive operations, but it requires the operators of the cable TV network to transform the current one-way transmission network into a two-way network, and this Requires a large investment of money and time
