Technical Field
The invention belongs to the technical field of telecommunication, and particularly relates to an interactive information processing platform for a digital television broadcasting system.
Background
The development of digital televisions depends on the balanced development of four links (digital television operators, program content providers, equipment suppliers and technical service providers) of the digital television industry chain.
Throughout the second digital revolution-the development law of the internet, mainly from colleges and universities, a set of HTML editing software is provided, so that the operation is simple and free, the participation is wide, and the individual creation content is more, so that the development can be realized greatly.
Like the development of the third-generation mobile phone content in japan, the great reason is that a small japan company develops a set of third-generation mobile phone content editing software, is simple to operate, and provides free download over the internet, so that hundreds of thousands of content creators in japan can create interactive content at will.
In comparison, the content creation of the interactive television is not limited to the content creation of several or dozens of professional companies, and the door closing and the vehicle building are also absolutely required.
If the content production and editing based on the interactive television under the independent development environment of the PC can be provided for tens of millions of computer users, the operation is easy like a Microsoft office automation software tool, and the content is uploaded to an interactive digital television content production center platform for testing, debugging and content classification and then transmitted to an associated television station, the digital television content production is simplified and popularized.
The content interaction production situation of the current digital television is summarized as follows:
1. the current situation in foreign countries:
the concept of the interactive digital television content production center platform only appears in singapore at present, and the operation is still in an experiment due to regional limitation and non-freeness of editing software.
