Description

Method for optimizing digital television interactive channel burst in digital home

[1] Technical field

[2] The present invention relates to the field of interactive digital television technology for digital homes, and more particularly to a method for optimizing the development of digital television interactive channels in a digital home.

[3] Technical background

[4] Communication technology, computer technology, and television technology are the three cornerstones of the information society. The high level of development and interpenetration of the three technologies can be realized through digital technology. At present, the boundaries between the three major industries of broadcasting, television, computer and communication are gradually disappearing. After the traditional media such as television, computer and telephone, a new kind of communication media-interactive digital TV has been born.

[5] Interactive digital TV is not only a new way to watch TV, but also a new concept of using the media. For ordinary users, no matter how advanced the interactive digital TV is and how wonderful the world is, they only touch its interface. For the user, the human machine interface is the system itself. The interface of the interactive digital television is the system of the interactive digital television itself for the user. A system without a good interface design can not be considered a success, because no matter how sophisticated the technology inside, as long as the user is not willing to use it, its superiority will not be played, its value and role can not be discussed. For a new thing like interactive digital TV, the design of its interface is decisive for its own development and application.

[6] With the rapid development of new generation computer multimedia technology and network and the implementation of a new generation of high-performance video image coding standards and the launch of high-performance encoding/decoding integrated circuit chips, digital TV interactive application services have good human-machine opportunities. The advantages of interactive and personalized services are widely used, and digital TV is gradually becoming practical and mature. But at the same time, in the process of digital TV interactive application development, how to make interactive applications and interactive service content receive digital devices through digital homes is convenient and quick to present on digital TV. At present, the functions of the digital home terminal middleware are different, the interactive application and the interactive service content are provided in different forms, the languages of the interactive application and the interactive service content are various and the complexity is inconsistent, and the performance of the digital home receiving terminal device is uneven, etc. There is no unified norm in the industry, and the development of digital TV interactive application service content is inefficient, non-standardized, and unhumanized. It hinders digital TV from presenting interactive service content to users in a better human-computer interaction.

[7] Summary of the invention

[14] (4) Describe and generate the corresponding code in the business logic text description language;

[15] (5) Integrate the code generated by steps (2) and (4) and store it in the database;

The framework template of the interactive frequency point service page presents various forms of interactive service content from navigation, list, content, etc. by analyzing various digital television interactive contents, and defines a template through the logical relationship between these elements.

[18] In the above technical solution, the definition process of the basic layout framework of the step (1) is: using basic interface design elements, summarizing several functional areas of the interface by using the morphological analysis method, combining human-computer interaction, and then passing The arrangement of these functional areas combines to form different templates, and finally through the logic between the areas Relationships to define template frameworks with different styles. Specifically in thousands of mobile digital TV (ITV) interfaces

After user-centered design principles are used to extract user intent, the initial interface is summarized and the basic interface design elements are used. The morphological analysis method is used to summarize several functional areas of the interface, combined with human-computer interaction, and then through these functional areas. The arrangement between the two forms a different template, and finally the template structure with different styles is defined by the logical relationship between the regions.

[19] The steps (2) used in the template description language are XML language.

[20] The XML language description definition framework template includes definitions of the basic data schemas in the template, as well as definitions of the logical relationships of the data schemas.

[21] The definition of the basic data schema in the template includes the definition of the following elements:

[22] Basic properties for defining common controls, including: control name, control unique identification number, control width value, height value, control background color, background image;

[23] Functional characteristics used to define data patterns;

[24] Used to define whether the data schema supports developer artificial modifications;

[25] is used to define which controls are supported by this data mode;

[26] Used to define the default layout for this data mode.

[27] The definition of the logical relationship of the data schema is the basic operational logic for defining the controls used in the data schema.

[28] The steps (3) define the business logic part of the framework to define the operational logic between the various data patterns in the composition framework.

[29] After calling the template description language on the development platform of the digital home digital television interactive service page, the invention can directly generate a corresponding interactive page frame, thereby realizing the development of the digital television interactive channel in the digital home. It can not only standardize the development of digital TV interactive channels in the digital home from the perspective of human-computer interaction, make the interactive of digital TV better presented to users, and enable developers to carry out related development work more efficiently and conveniently. Thereby promoting the digital home industry to move forward better.

[34] Specific implementation

[35] The present invention will be further described below in conjunction with the accompanying drawings.

[36] The implementation process of the present invention is as shown in FIG. 1. First, a framework template of an interactive service frequency page is summarized in the interface of thousands of digital television interactive channels, and the XML language is combined with the interaction design principle. Describe the basic elements of the template to form the template code; then, for the operation logic of the digital TV set-top box remote control and the business logic of the corresponding template, and convert them into code; then combine the two parts of the code to form the source code of the corresponding frame Finally, the obtained template source code is stored in the database. In the development of digital TV interactive channel, the corresponding template code of the database can be directly called on the terminal development platform for visual development, thereby optimizing the development process of the interactive interface, and improving the working efficiency of the developer.

[37] The specific implementation steps of the optimization method for the interactive channel development of the digital television set-top box of the present invention are as follows:

[38] 1. Summarize the layout framework of a set of interactive service pages.

Figure 2 is a flow chart of the interactive frequency point service page template generation process, showing the basic idea of the present invention summarizing the interactive service page layout framework. First, in the developed set-top box interactive page, it is described according to the principle of interactive design; then, according to the structural model, the existing page is structured to obtain a structured understanding, analyze the layout of the page, and get the page. The basic data model; then use the morphological analysis method established by Dr. Zwicky to arrange and combine the basic data patterns; finally, the combined operation logic of the page can be used to obtain the corresponding page template.

[40] Figure 3 is a schematic diagram of the basic control framework of the interactive frequency point service page. It can be seen from the figure that there are a total of eight templates formed after the summary, and two pop-up boxes, one free box. There are six basic control elements for each template: button, text box, single-select list, multi-select list, text area, label. The area layer is the data mode of the template, which is divided according to functions: title area, navigation bar area, list area, public prompt area, free layout area and content area.

[41] 2. Define the template framework using the XML language description of the interface.

[42] The framework template is defined in XML language, and the main definitions are as follows:

[43] Al, the definition of the object model in the template; [44] A2, the definition of the functional model in the template;

[45] A3, the behavioral definition between the internal behavior of the object function in the template and the functional model;

[46] Among them, the definition of the basic object model in the A1 template includes the definition of the following elements:

[47] Basic properties for defining common controls, including: control name, control unique identification number, control width value, height value, control background color, background image, etc.

[48] For the definition of the basic functional model in the A2 template, including the definition of the following elements:

[49] Functional characteristics used to define data patterns (objects of functional models);

[50] Used to define whether the data pattern supports developer artificial modification;

[51] Used to define which controls are supported by this data mode;

[52] The default layout used to define this data mode.

[53] For the definition of the basic behavior model in the A3 template:

[54] Because the data pattern is rearranged and combined to get the page template, the template is defined by the logical relationship between different data patterns. The logical part of the framework contains definitions of the logical relationships between data patterns and other definitions of the logical relationships associated with the page. In the basic interactive page, the user-used operation keys are: Up, Down, Left, Right, OK, Back, Exit, or Page Key. Since there is a certain logical relationship between the interface elements, there is also a logical relationship between the data modes. Different layouts, the operations to be performed on the remote controller are different. Different objects have their own definitions of these operations, which will be described in more detail in the task model. The operation between the basic data modes mainly refers to how to switch and jump between the operation attributes inside the data mode and the different data modes inside the template. Then, in the data mode, what operations are used by the remote controller; It is logical to define which operations can be switched between the remote control and so on.

[55] 4. Describe and generate the corresponding code in the business logic text description language.

[56] After describing these logical relationships in a text description language, the corresponding code of the business logic layer is obtained through transcoding.

[57] 5. Integrate the code generated by (2) and (4) and store it in the database.

[58] After synthesizing the business logic layer code obtained by converting the logical relationship between the code formed by the basic elements of the page and the basic mode in the page, the source code of the page template is obtained. Store the source code of all templates in the number The word TV interactive channel is visualized in the database on the development platform. In this way, when the developer develops on the platform, only the corresponding framework needs to be called for the specific page, and the framework code can be directly generated in the background. Then visual design and development on the framework can quickly get the page, which fundamentally improves the development efficiency of the interactive page.
