Apparatus and method for precise search and detailed viewing of TV programs based on one-way network

Abstract

The invention discloses a television program precision searching and detail viewing device and method based on a one-way network. An EPG (Electronic Program Guide) unit and a front-end data broadcasting unit positioned at the front end of the one-way network are arranged; a program information processing unit, a program storage unit, a Chinese characters spelling processing unit, a program searching unit and a terminal data broadcasting unit are arranged on a one-way receiving digital television set-stop box; and the program information processing unit, the program storage unit, the Chinese characters spelling processing unit, the program searching unit and the terminal data broadcasting unit mutually call software modules in operation through API (Application Programming Interface). By using the device and method disclosed by the invention, the precision searching and detail viewing of the program information can be realized through direct engineering application without making any modification to the current network; the user can obtain detailed program content introduction through associated web pages so as to solve the problems that the programs are hard to look up and the details cannot be viewed; and the using effect of the EGP is provided so that the adhesion of the digital television user to the digital television application is enhanced.

Description

technical field [0001] The present invention relates to digital television, in particular to a device and method for accurately searching and checking details of television programs based on a one-way network. Background technique [0002] The existing broadcasting and TV networks in domestic cities are still dominated by one-way digital TV transmission networks. One-way receiving digital TV set-top box (Set-Top Box, abbreviated as STB) users provide a weekly program list in the form of Electronic Program Guide (Electronic Program Guide, abbreviated as EPG). Find the programs broadcast by various channels this week, and reserve the programs you care about, and the set-top box will remind the user to watch them at the scheduled time. However, for digital TV set-top box users who can watch 100 TV channels and each channel has 20 programs a day for one-way reception, there is no Chinese character and letter input function, and the remote control can only be operated by pressin...

Problems solved by technology

However, for digital TV set-top box users who can watch 100 TV channels and each channel has 20 programs a day for one-way reception, there is no Chinese character and letter input function, and the remote control can only be operated by pressing the channel keys one by one in different programs. It is cumbersome and time-consuming to switch from the 100×20×7=14,000 programs in a week to find the program you want to watch. It is difficult to complete the browsing of all information and has to stop halfway; it reduces the user’s search for program information. enthusiasm, which leads to a lot of program resources being wasted, and the advantages of rich digital TV program resources cannot be reflected

Moreover, the one-way digital TV transmission network is limited by the description of digital TV service information. In the EPG, only simple program classification and brief program text information can be seen, and there is no function of recommending related programs. There are very few ways to attract users to choose programs. , the user cannot obtain detailed program information

In addition, systems and devices that use two-way to search for programs and program information cannot be used in a purely one-way environment
