Design scheme of high-definition digital set-top box navigation operating system

June 23, 2020

1 Introduction

The current high-definition set-top boxes basically follow the operating system of standard-definition set-top boxes. However, the total number of digital TV channels has reached more than 140 sets. The high-definition channels that have been connected to the Internet have been ranked out of 130 in the EPG channel list. Convenience, which is an unfavorable factor for the marketing of high-definition channels, this problem has been reflected in the marketing of median pay channels. At present, the contradiction between the increasing number of new channels and the inconvenience of channel selection is becoming obvious, which will cause obstacles to the promotion of our new business. Therefore, it is very necessary to upgrade the operating system of the HD set-top box to make the channel selection and other various This operation is more convenient and intuitive to adapt to the next promotion of HD channels and other new services.

2 Design of navigation operating system for HD set-top box

The author believes that each business and operation function should be divided into modularized categories, borrowing from the current mainstream consumer electronics operating system model, using a navigation-type operating system, and using the M & TImes; N Gongge icon on the main menu to indicate that Various services and functions are more intuitively presented to the user, while planning the hierarchical structure and control process of each service and function, simplifying and optimizing the remote control buttons, and bringing more convenient and comfortable interaction to the user with an intuitive interface and convenient operation Operating experience.

2.1 Business module planning of the main interface

The main interface classifies and displays various business and operation functions in the form of 3 rows, 4 columns and 12 squares, as shown in Figure 1, which are basic channels, median channels, high-definition channels, radio broadcasting, video on demand, video carousel, 12 items of data broadcasting, stock information, system settings, favorite channels, treasure chests, and information prompts. The location of business and function icons generally follows from top to bottom in terms of TV programs, information services, and system functions. The user utilization rate is high The business and functions are placed in the left and middle positions, making the operation more convenient.

2.2 Operating system structure planning

The overall hierarchical structure plan of the HD set-top box operating system is shown in Table 1.

2.3 Optimized design of remote control

With the navigation operating system, the remote control buttons are set based on the principles of easy operation and perfect functions. They are coordinated with the display interface. The layout is 11 rows and 3 columns. The remote control can be divided into 5 functions from top to bottom. Areas are sound setting and power switch area, digital key area, function area, navigation area, additional function area. as shown in picture 2. The layout of each function area fully considers the convenience of the user ’s thumb operation and the frequency of use of various functions. The navigation keys (confirmation key and four direction keys) are the core keys of this navigation operating system and are set on the remote control The lower 1/3 position, this area is the best operation position of the thumb, which is more comfortable and convenient when operating.

What is a wall GFCI socket?
A wall GFCI socket is different from conventional sockets. In the event of a ground fault, a wall GFCI socket will trip and quickly stop the flow of electricity to prevent serious injury.
Wall GFCI socket protect You From Electric Shock Due To:
1.With safe lock protection function,wall GFCI socket safety is improved.when miswired,wall GFCI sockets have no power and can not be reset,so it is more safe than conventional socket.
2.The wall GFCI socket includes end-of -life monitoring function,it can not reset correctly when the wall GFCI socket reaches the end of life.
3.Improved resistance to surge and corrosion.
4.Easier installation.(installation instructions enclosed)
