The invention provides a multi-path video data acquiring, processing and transmitting device and a method thereof. The device consists of a data acquisition module, a main data processer, a storage module and an output module, wherein the data acquisition module, the storage module and the output module are connected with the main data processer; the data acquisition module is externally connected with video equipment; and the output module is externally connected with a video dividing and superposing unit and a video display unit. The method for the device comprises the following steps that:after the data acquisition module acquires video signals of the video equipment, an acquisition and configuration module processes the video signals and sends the video signals to the main data processer; the video signals are processed by the main data processer and then cached into the storage module; and finally, the main data processer reads data from the storage module and sends the data to the output module. The device has a simple structure and stable output, and at least can support input of 16-path video streams with standard definition.
Description
technical field [0001] The invention relates to video data processing technology, in particular to a device and method for collecting, processing and transmitting multi-channel video data.
