Digital television system, front-end device and unidirectional set top box

Abstract

The present invention discloses a digital television system, a front-end device and an unidirectional set top box. The digital television system issues a power-on picture file storing a corresponding relation of region codes an power-on picture addresses through a front-end device to allow a unidirectional set top box to obtain the power-on picture file and update built-in power-on pictures according to the power-on picture file and the built-in region codes to allow a terminal to display the power-on pictures corresponding to the region codes at a starting phase so as to realize the purpose that unidirectional set top boxes at different areas display different power-on pictures; and the digital television system does not need customize unidirectional set top boxes storing different power-on pictures for different areas so as to reduce the customization cost and the maintenance cost of the unidirectional set top box. Furtherly, the digital television system does not need to integrate an advertisement system for the front-end device and does not need to integrate an advertisement bank for the terminal so as to reduce the cost of the digital television system.

Description

technical field [0001] The present application relates to the technical field of digital television broadcasting, and more specifically, relates to a digital television system, a front-end device and a one-way set-top box. Background technique [0002] Digital TV, also known as digital TV or digital TV, means that all links from the studio to the launch, transmission, and reception use digital TV signals or all signal transmission of the system is made up of 0 and 1 digital strings. A type of television in which a stream of binary digits is transmitted, as opposed to analog television. The signal loss is small and the reception effect is good. [0003] In a digital TV system, a set-top box is an intermediate device that receives and parses the code stream data sent by the front-end equipment and delivers it to the terminal for playback. It is distinguished by communication methods. The set-top box is mainly divided into two-way communication with the front-end equipment thr...

Problems solved by technology

[0004] In a traditional one-way set-top box, the booting screen of the terminal is usually a picture solidified inside the set-top box. If you want the one-way set-top box to display different booting screens in different areas, usually by The one-way set-top box of the picture can be realized. The customization cost of the one-way set-top box in this way is relatively high, and the maintenance difficulty of more versions of the one-way set-top box is relatively high, and the maintenance cost is relatively high.
