The development of information release system

According to the data of foreign companies, the United States in 2009-2010 multimedia information display (Digital Signage) market maintained a growth of 2.0%, reaching a market size of $ 2.47 billion. The global growth rate of 4.7%, reaching a size of $ 6.69 billion.　Meanwhile, they predict that the industry will grow at a rate of 9.4 percent in the U.S. and 10.1 percent globally over the next four years (ending in 2014).

According to their analysis, the current multimedia information display industry also has the following problems:

Lack of big brand, the formation of scale operators;

Facing the increasing competition from other new media channels;

From the industry trend, there are the following changes:

Multiple formats, rich associated content display trend;

The trend to become a mainstream media, similar to the early trends of radio, television and the Internet;

Globally, China, India, Brazil, and Canada will be the fastest-growing markets; in Asia Pacific, the market for multimedia information displays grew at a rate of 10.7% in 2009 and reached a market size of $2.18 billion

Development

Development history

In China, digital signage is a key component in the development of the digital signage industry. p>In China, digital signage or electronic bulletins are collectively referred to as digital multimedia information distribution systems.

The early domestic information broadcasting method has no systematic concept, but the basic structure and function is still the same. Early information dissemination system composition: DVD player, stand-alone playback, VOD server + set-top box.

Since 2007, with banks, hospitals, transportation, shopping malls, schools, supermarkets, stadiums, airports and other areas of networking-type information dissemination needs, the earlier stand-alone advertising player has not been able to meet the needs of customers, and in its place is based on a network platform to provide real-time, centralized control of the management and automation of the broadcast of digital multimedia information dissemination system.

Due to the different design concepts and application areas in the early days, there are two major development schools, namely, PC-based platforms and specialized platforms based on the two architectures. The following is an introduction to the development of these two architectures and the future outlook:

One, based on the PC platform multimedia information dissemination system

Between 2003 and 2007, a number of domestic companies with a background in software development have developed a PC-based platform multimedia information dissemination system.

Based on the PC platform multimedia information dissemination system contains windows-based professional playback management software and X86 player, and through the C / S or B / S or C / S and B / S combination of network distributed structure will be divided into various levels of equipment connected to centralized management and control.

System features:

1. Support for various multimedia formats. In addition, a good scalability architecture can be subsequent development of new media formats are well compatible with in.

2. Provide a variety of front-end playback of the screen split template, and can provide customers with customized and self-made template software modules and tools.

3. Powerful third-party access applications, such as: bank inquiry system, real-time exchange rate system, automatic real-time weather forecast information.

4. Support dual-screen display, vertical display, real-time cable TV signals and so on.

Two, based on a dedicated platform for multimedia information distribution system

Based on a dedicated platform for multimedia information distribution system is the use of embedded platforms, the most classic case to be used in the 2008 Beijing Olympic Games arena is a digital broadcast control system. The development and application of broadcast control system is a milestone in the domestic broadcast control system, which rapidly promoted the domestic broadcast control system towards industrialization, functionality, serialization of the direction of development, but also makes the dedicated platform based multimedia information dissemination system has become the mainstream trend of China's multimedia system development.

The functional features of the system include:

1. Unlike the PC-based platform multimedia information distribution system, the embedded system has strong system stability and security, and the RISC player has low power consumption and meets the characteristics of 7×24-hour all-weather work, which is a cost-effective system.

2. Work on LAN, WAN, ADSL, ISDN and the Internet, can be remote synchronized control of multimedia content playback on a number of display screens, remote control of a number of different locations within the building and even different cities within the display, support for continuous playback for many weeks to many months.

3. The system is highly convenient to use, distributed around the production staff do not need to download the production software, do not need in-depth training to produce, very convenient and low-cost.

4. Expandability of the system and low maintenance costs.

The development trend:

Based on the PC platform multimedia information dissemination system and based on a dedicated platform multimedia information dissemination system two technologies have their own strengths, will be based on different applications and long-term coexistence of the two technologies. For example: in the application of advertising operation, due to the large number of screens, scattered in different areas, the content format is more uniform, to provide system stability is very important, suitable for the use of a dedicated platform based on multimedia information dissemination system. In some small and medium-sized projects, such as the government, banks and other areas, the requirements of the system is rich in content, and support for a variety of formats of documents, suitable for the use of PC-based platform multimedia information distribution system.

Outlook:

According to the market experience of developed countries, China's multimedia information advertising market is just the tip of the iceberg surfaced, the future of both the market share or market size has a huge growth space. Domestic outdoor media operators have put digitization on the agenda, multimedia information distribution system will usher in a greater opportunity for development. Multimedia information dissemination system is a set of information display platform that can release rich content and exquisite picture, and can customize the broadcast content to realize the combination of multimedia information such as video, audio, Flash animation, picture advertisement and scrolling subtitle, etc., and display a variety of information on a big screen such as news, entertainment, sports and weather forecast.
