摘要： Disclosed are a decoding method based on an adaptive intra-frame refreshing mechanism, an encoding method based on an adaptive intra-frame refresh mechanism, and a related device, which belong to the field of video encoding and decoding. In the embodiments of the present application, an adaptive intra-frame video refreshing extension number and virtual boundary location mark information are newly added to extended data in a code stream of the current frame. In this way, since virtual boundary location mark information can indicate the location of a virtual boundary, and the virtual boundary is at least used for distinguishing between a refreshed area and a non-refreshed area in the current frame, when dividing the refreshed area of the current frame, an encoding terminal can arbitrarily set the virtual boundary on the basis of actual demands, and indicate the location of the virtual boundary by means of the virtual boundary location mark information, thereby effectively improving the flexibility of area division.

摘要： Embodiments of the present application relate to the technical field of communications. Disclosed are a method and apparatus for establishing communication connection, and a device, and a computer readable storage medium. The method comprises: establishing communication connection with a server on the basis of a first port, the first port being a port through which a client negotiates with the server, or, the first port being a port used when the client communicates with the server last time; in the case that establishing the communication connection with the server on the basis of the first port fails, reading port information in target configuration data, a second port indicated by the port information in the target configuration data being used for establishing the communication connection between the client and the server; and establishing the communication connection with the server on the basis of the second port. The client does not need to traverse a plurality of ports but can directly determine, by reading the target configuration data, the second port that can be used for establishing the communication connection with the server, and therefore, the time required for establishment of the communication connection between the client and the server can be shortened, thereby improving the communication efficiency.

摘要： The present application discloses a method for generating a network topology, which determines multiple designated devices in a network, wherein the multiple designated devices are directly or indirectly connected through ports. The accessible devices corresponding to the ports of the designated devices among the multiple designated devices are determined, wherein any accessible device corresponding to a port of a designated device is directly or indirectly connected to the designated device through the port. A root node device among the multiple designated devices is determined according to the number of accessible devices corresponding to the ports of the designated device(s). The designated devices that are directly connected among the multiple designated devices are determined according to the accessible devices corresponding to the ports of the designated devices. The topology of the multiple designated devices in the network is generated according to the root node device and the designated devices that are directly connected among the multiple designated devices. Thus, the topology of multiple designated devices in the network is automatically generated according to the accessible devices corresponding to the ports of the multiple designated devices in the network, which is simple, efficient and accurate.
