2 results about "Multimedia storage" patented technology

The application discloses an embedded multimedia memory card and a monitoring system and method for data transmission thereof, and belongs to the technical field of data storage. The system comprises an address monitoring unit, a data monitoring unit, an expected value buffer unit and a comparison unit. The address monitoring unit is connected in parallel to an address channel and a write control channel of a transmission bus of the embedded multimedia memory card, and outputs a trigger signal when the write control channel is a write operation and a current address on the address channel belongs to a preset target address range. The data monitoring unit is connected in parallel to a write data channel of the transmission bus of the embedded multimedia memory card, and is used for acquiring actual write data of the write data channel when the trigger signal is acquired. The expected value buffer unit is used for storing expected data corresponding to the preset target address range. The comparison unit is used for comparing the actual write data with the target expected data in real time, and outputting an error flag signal in each clock cycle according to a comparison result.

A server management system and method, a device, a computer program product, and a medium, relating to the technical field of servers. The server management system comprises a management controller (10), a data selection device (20), and a multimedia storage device (30). The management controller (10) and the data selection device (20) can allow for switching between using and not using a target video transmission interface. When the target video transmission interface is used, some of data pins of a multimedia storage interface in the management controller (10) establish a connection with the multimedia storage device (30), and function-multiplexing pins are used as a serial clock pin and a series data pin and establish connections with the target video transmission interface, so that the target video transmission interface can be normally used. When the target video transmission interface is not used, the function-multiplexing pins of the multimedia storage interface are used as the data pins, and each data pin establishes a connection with the multimedia storage device (30), so that data read and write operations of all data bit widths of the multimedia storage device (30) can be implemented, thereby ensuring a data read / write rate.
