Abstract

The invention provides a streaming media broadcast system, a streaming media broadcast method and an LED display screen system. The streaming media broadcast system comprises a streaming media processing module; the streaming media processing module comprises a code source control submodule, an inner core submodule, and a video processing submodule; the code source control submodule comprises a receiving processing unit and a first data-caching mechanism; the inner core submodule comprises an audio / video separating unit, a video decoding unit and a second data-caching mechanism; the video processing submodule comprises a video processing unit and a third data-caching mechanism. According to the invention, streaming media broadcast on an asynchronous control system for an LED display screen is realized; as a three-level data-caching mechanism technology is adopted in the design of the media player, the fluency of real-time media video broadcast is improved; conditions of blocking and nonfluency are reduced.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a streaming media playing system, a streaming media playing method and an LED display screen system. Background technique [0002] The widespread use of LED full-color displays makes the development of LED full-color display control systems extremely urgent. Since the control requirements put forward by various businesses are different, the functions realized by each display screen control system are also different. Different control systems must be designed for different customer needs. [0003] Since the traditional synchronous control system must transmit the display information and various control commands to the LED display control system through the serial communication through the PC for display, this method is inseparable from the help of the PC, so for remote Distance transmission and so on all bring certain troubles. At present, various asynchronous control systems ...
