Digital media content service gateway system based on media analysis

Abstract

The invention provides a digital media content service gateway system based on media content analysis. Firstly, a mobile terminal information acquisition module acquires mobile terminal device parameters and resource address information to be accessed by a user, the digital media content resource address information to be accessed by the user is sent to a digital media content value evaluation and analysis module, and the mobile terminal device parameters are sent to a digital media content adaptation decision-making and processing module. The digital media content value evaluation and analysis module performs value evaluation on constitutional units in digital media based on a media content value evaluation model and generates digital media content value scores; and according to the digital media content value scores and analysis the results of the analysis module and through combining the mobile terminal device parameters and network environmental performances, the digital media content adaptation decision-making and processing module adopts corresponding adaptive operations to digital media content resources stored by a digital media content resource management database module and sends adapted content to the mobile terminal.

Description

technical field [0001] The invention belongs to the field of wireless multimedia communication, and in particular relates to a digital media content service gateway system based on media analysis. Background technique [0002] In the 21st century, the digital content industry produced by the integration of digital media technology, network technology and cultural content is growing rapidly all over the world. my country is also vigorously developing various digital media content operation comprehensive services based on different networks and different terminals, such as mobile value-added, digital TV, IPTV and other fields. Important progress has been made, and different networks and different services are being integrated. With the establishment of 3G networks of major operators, mobile digital media content service will undoubtedly become one of the most important services and applications with the broadest prospects. Relevant data point out that by 2012 the mobile video...

Problems solved by technology

The above two adaptation technologies are based on the rate-distortion model and aim to optimize the rate-distortion characteristics. The main problem is that the objective quality indicators after adaptation can achieve better results, but the user's visual quality may not be guaranteed; Moreover, because the accurate rate-distortion model is difficult to obtain, the reduction of encoding rate and resolution has great limitations.
