Abstract

The invention discloses a safe storage method and a system in the process of real-time data acquisition, belonging to the technical field of data storage. When the prior broadcast television receiving and recording system receives and records multimedia data, the data is directly stored in a target memory with convenient application, thus the requirements to network environment and a disk system are extremely high, however, due to the complexity of software and hardware of a computer network system, the safe and reliable network environment not only needs enormous investment, but also can notprevent accidents from happing completely. In the method and the system of the invention, when the target memory works abnormally, a data scheduling module can record the operation and data of the target memory into a process recording module, and meanwhile, a process restoring module is started; and when the target memory restores to normal, the process restoring module restores the data into the target memory. By adopting the method and the system, the security requirements to the network environment and a memory device are reduced, and the data integrity can be ensured when the impermanentfaults of the environment appear.

Description

technical field [0001] The invention belongs to the technical field of data storage, and in particular relates to a safe storage method and system in the process of real-time data collection. Background technique [0002] Today, with the rapid development of network and digital technology, satellite technology has been widely used in the fields of broadcasting and communication. A large number of TV programs are broadcast and exchanged through satellite transmission, and together with the terrestrial TV network, they form a broadcast TV network covering the whole world. The digital and intelligent real-time data acquisition system (hereinafter referred to as the recording system) has become a popular choice for TV stations and media units due to its powerful functions such as the ability to receive multiple sets of programs from multiple satellites, download them simultaneously, and automatically collect TV programs on each satellite. It is an important means of obtaining p...
