一、Project background

With the rapid development of social informatization, the whole society pays more and more attention to the dissemination and communication of information. The traditional print publishing mode has been replaced by the three-dimensional and network publishing mode of multimedia information. The emergence of digital multimedia information publishing system based on the Internet provides the whole society with better means of information publicity and display, and also provides a brand-new advertising operation platform for the advertising media industry. Our company complied with the needs of the times and successfully developed the information release management system through independent innovation, which has reached the top level in China, provided the most modern means of information display and communication for various activity places, and achieved certain social and good economic benefits.

The information publishing management system can easily build a centralized, networked, professional, intelligent and diversified large-scale digital business hall information publishing platform, and provide powerful professional media services such as information editing, transmission, publishing and management. According to the current information dissemination demand, the multimedia information publishing system takes economy, ease of use, safety, foresight, expansibility, advancement and practicality as its design ideas, and adopts centralized control and unified management to transmit multimedia information such as video and audio signals, pictures and rolling subtitles to display terminals and inquiry terminals through the network platform, which can effectively cover the crowded places in the public (halls, office areas, entrances, etc.) in the business hall. Play various image videos, public service videos, public information announcements, welcome speeches, rolling subtitle announcements, etc., and immediately release public information such as weather forecast, city traffic information and various news, and deliver the freshest information to the audience at the first time. According to different regions and audience groups, manage the information by levels and regions, and release the information in a targeted manner, so as to make the information in the business hall open, and truly serve the people in time and use the information for the people in time.

In order to improve the information application level of the business hall and promote the digital construction process of the business hall, the goals achieved through the ZAXTEAM multimedia information publishing management system are as follows: 1. Realize centralized editing control, remote management and online publishing of information in the business hall; Second, use rich and diverse multimedia forms such as text, images, audio and video to improve the attention and visibility of information; Third, timely and accurately publish various notices, public welfare information (news, weather, recommendations, etc.), welcome words, public service guidance information, etc.; Four, play a variety of image publicity clips, advertising clips, public service advertisements, rolling subtitles notice, etc., to improve the service level and overall image of the business hall.

5.3Broadcast management

Define the layout, program package, and play plan through the ZAXTEAM information publishing service platform, and send them to different terminals to control the terminal’s broadcast behavior. Before introducing the specific operations, first explain a few concepts involved here. Area: The platform defines several types of areas for playing different types of media materials. Specifically include: main area, play area, text area, date area, weather area. You can customize the location and size of the area, and you can customize the playback characteristics of the area for specific media materials. For example, for the text area, you can set whether the text scrolls, scroll speed, color and other attributes.

Layout: a collection of multiple areas, this collection constitutes a complete screen.

Program package: Fill the layout with media content to form a complete media content package that can be played by the terminal.

Broadcast plan: add a schedule to the program package to form a broadcast plan.

Generally speaking: media materials belong to the region; multiple regions constitute a complete layout; the layout containing the content constitutes a program package; the program package plus a time plan constitutes a broadcast plan.

The broadcast plan is issued to the terminal, and the terminal can download the media material according to this plan, and carry out the broadcast activity according to the plan.

5.3.1Layout design

Add area to the layout, set the location, size, and playback attributes of the area, add multiple areas covering the entire screen, and complete a layout design.
