Multiparameter media adapter gateway and adaption method thereof

Abstract

The invention relates to a multiparameter media adapter gateway and an adaption method thereof. The multiparameter media adapter gateway comprises an adaption control unit and a two-layer of stream transmission unit structure, wherein the adaption control unit comprises a session information base module, a parameter statistics module, an analysis and decision module, a stream adaption control module and an adaption utility feedback module; and the stream transmission unit comprises a decoding module, a coding module and a stream distribution module. By the invention, the setting times and quality of session for the multimedia service under a heterogeneous network environment can be improved, and meanwhile, calculating expense and resource consumption of a streaming media server can be reduced; and the media is adaptive to be as an independent unit, so that the deploying flexibility of a whole streaming media system is improved, meanwhile, the design of the multimedia adaption scheme has good expansion, different adaption parameter sets can be quickly added to a decision tree model, and the weighting of the adaptive parameters can be subject to statistic updating according to self-adaption feedback. Further, the invention better meets the requirements of the actual media adaption application scene.

Description

technical field [0001] The invention belongs to the field of multimedia communication, and in particular relates to a gateway capable of integrating and adapting various media parameters required for media sessions under a heterogeneous network and an adaptation method thereof. Background technique [0002] With the rapid development of digital media applications, media adaptation, as a necessary link to meet general media access, plays a pivotal role in the pervasive media environment. [0003] Due to the complex network environment, available bandwidth, service quality, and delay jitter under heterogeneous networks; physical environment such as device capabilities (resolution, media support type, processor, power), channel characteristics; user experience such as media content, media type , user preferences, session satisfaction and many other factors that affect media services are important indicators to measure the quality of media services. In a heterogeneous network e...

Problems solved by technology

[0004] Traditional media adaptation is mainly based on the characteristics of existing media sources, and the adaptation process is mainly carried out in the encoding and compression domain, and is generally integrated in the media server, which is not flexible enough to directly meet user needs, and only provides The most basic code stream adaptation ensures that media access can be performed with the lowest user experience
