Abstract

An audiovisual broadcasting equipment comprising a data input interface, an analogue digital converter, a capture circuit, and a processing unit recorded with program codes, wherein, the data input interface receives an analogue data which carries a digital update data inside from a data source, the analogue digital converter converts the analogue data into the digital format and transmits it to the capture circuit, then the digital update data is captured by the capture circuit and sent to the processing unit for updating the interior program code therewith.

Description

technical field [0001] The invention relates to a system update method, in particular to a system update method for audio-visual playback equipment. Background technique [0002] Due to the gradual improvement of people's requirements for the quality of life, the vigorous development of many household appliances has been promoted, and home audio-visual playback equipment is a notable example. In addition, due to the implementation of the two-day weekend in recent years, the trend of tourism and leisure has become more and more popular. In order to pass the time of driving during long-distance travel, the existing audio playback system that is only mounted on the car can no longer satisfy users, so the video playback equipment is also slowly developing towards the field of vehicles. At present, car audio-visual playback equipment is the standard equipment of many RVs. [0003] Fig. 1 shows a schematic diagram of updating the firmware of a known audio-visual playback device....
