Abstract: In a data processing method, data to be processed are obtained by a first electronic device. The first electronic device receives operation information of multiple second electronic devices from the multiple second electronic devices, determines target devices from the multiple second electronic devices according to the data and the operation information, and divides the data into data blocks according to the operation information. The data blocks are sent to the target devices for processing. The method improves the efficiency of data processing.

Abstract: A software updating method is applied in a device governing an internet of things (IoT). A public key of a server and software updating information of an adjacent device is broadcast as control information by the server, the IoT device encrypts the software updating information according to the public key of the adjacent device, sends the encrypted software updating information to the adjacent device, and downloads software updating information from the adjacent device. When the control information includes address for storing the software in the server and the software updating information of the adjacent device, the IoT device downloads the software corresponding to the software updating information from the adjacent device.

Abstract: A data processing method, an electronic device and a non-volatile storage medium are disclosed, the method includes selecting a next to be executed thread and determining whether the selected thread is a high-performance thread. If the selected thread is a high-performance thread and a thread-user of the on-chip memory is not the selected high-performance thread, contents of the on-chip memory are backed to a stack memory of a thread corresponding to the thread-user. Contents of a stack memory of the selected thread are backed to the on-chip memory. The thread-user of the on-chip memory is updated to indicate the selected thread. The contents of the on-chip memory in a CPU register is stored to complete the switching out; and the selected thread is executed. The present disclosure can accelerate and speed up data processing.

Abstract: Disclosed is an IP camera and a video playback method thereof, the IP camera connected to a host through the network, the IP camera includes an image capturing unit, a processor, and an input/output buffer unit. An external video is captured by the image capturing unit, and the external video includes a plurality of frames. An image outputting rate is determined by the processor, and an output external image is produced by reducing a resolution of the external image and remarking a confirm flag in at least one first frame when an image output rate is lower than a threshold value. The external image or the processed image is inputted to the I/O buffer unit to form an output external image. By way of the present invention, the captured video may still be watched instantly and fluently on the host while the host is suffering from the network congestion.

Abstract: A large-size electronic file storage and retrieval handling method and system is proposed, which is designed for use with a file management system on a computer platform that has an upper file size limit, with the purpose of providing the file management system with a large-size electronic file storage and retrieval handling function, which is characterized by the capability of dissecting a large-size file whose size exceeds the upper file size limit into a number of small-size files each with a size less than the upper file size limit, so as to allow each single large-size file to be stored into and retrieved from the computer platform in batch. This feature can be utilized on any types of computer platforms to allow the storage and retrieval of electronic files of any unlimited large sizes.

Abstract: A data-updating method for an embedded system capable of coupling with a network communication apparatus is provided. The embedded system containing data to be updated is searched through a network by the network communication apparatus using network resources. Networking data stored in the embedded system is accessed by the network communication apparatus which is subsequently linked to a corresponding network resource location using the networking data. Then, the data within the network resource location is modified, updated or downloaded using the network communication apparatus. The modified, updated, or downloaded data is then stored in a storage unit of the network communication apparatus using the network communication apparatus. Lastly, the data of the embedded system is updated in a conventional file updating manner using the network communication apparatus.
