Channel environment adaptive method and narrow bandwidth conference system

The invention provides a channel environment self-adaption method and a narrow bandwidth conference system, and belongs to the technical field of communication, a data source module is used for converting received audio and video code streams and equipment code streams into a unified protocol meeting an internal interface; the target module is used for converting a uniform protocol code stream transmitted by an internal interface of the system into code streams meeting different interfaces and different protocols and supporting decoding display and transmission of audio and video code streams; and the scheduling module is used for coordinating code streams in the system, managing the connection relationship between the data source module and the destination module, and forwarding media parameters of a coding end at the same time. According to the invention, a plurality of independent devices can establish a group conference in a satellite narrowband environment to form a video and audio conference system, the
