Problems solved by technology
[0004] (1) Only a single device can be used to perform multimedia processing of exchange data requested by a certain business. When a single device performs multimedia processing with a huge amount of computation, the speed is slow and the efficiency is low. Even if there are multiple devices in the system, it cannot be executed. Parallel processing causes waste of system resources
[0005] (2) Traditional AVI and other media format data can only perform multimedia processing when the entire file is complete. For TV programs with good timeliness, it cannot meet the requirements of editing and collecting exchanged data
However, the existing TV production field has not implemented a multimedia data processing system for supporting MXF

Embodiment Construction
[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the embodiments of the present invention will be further described in detail below in conjunction with the embodiments and the accompanying drawings. Here, the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not to limit the present invention.
[0024] figure 1 Shown is a schematic structural diagram of an embodiment of the multimedia data processing system of the present invention. figure 1 The MXF-based multimedia data processing system consists of an exchange data storage device, a scheduling server, multiple servers, a main server, and a target data storage device. The exchange data stored in the exchange data storage device is complete data encapsulated in the material exchange format; the scheduling server receives externally input service requests such as media format conversion re...

The invention provides a multimedia data processing system based on a material exchange format and a method thereof. The system comprises an exchanged data storage device which stores the complete data encapsulated by the material exchange format, a scheduling server which queries the number of idle data processing units corresponding to the type of multimedia service requests, and divides the complete data encapsulated by the material exchange format into mapping data segments corresponding to the number of a plurality of data processing units, and distributes the mapping data segments to the data processing units, a plurality of data processing units which process the data mapping segments in parallel to generate target data segments, a data merged unit which merges the data mapping segments sent by the data processing unit to target data; a target data storing device which stores the target data. The invention provides the multimedia data processing system based on a material exchange format and the method thereof to realize the parallel multimedia processing of the same exchanged data by a plurality of servers.
Description
technical field [0001] The present invention relates to multimedia data processing technology, specifically a multimedia data processing system and method based on Material Exchange Format. Background technique [0002] The existing TV program editing and broadcasting process generally includes the following steps: the program production network of the TV station transcodes the program materials recorded by external devices such as video recorders, cameras, satellite receivers, etc., adds subtitles, extracts key frames, dubbing and other post-editing work . After the post-editing is completed, the produced TV programs will be broadcast on the TV station network. When exchanging data between the TV station's program production network, broadcasting network, and media asset network, as well as between each network and the above-mentioned external equipment, special equipment must be used for data collection and conversion processing. [0003] But existing multimedia data pro...
