Abstract: Video coding methods, apparatuses, and non-transitory computer readable mediums are provided. The method includes: obtaining a list of reference pictures comprising a plurality of pictures stored in a buffer, where the plurality of pictures comprise at least a first picture with a first spatial resolution, and a second picture with a second spatial resolution different from the first spatial resolution; obtaining a reference picture from the list of reference pictures; predicting a current picture by using the reference picture with its original spatial resolution without ensuring the reference picture to have a same spatial resolution as the current picture; and generating a bitstream based on a predicted current picture.

Abstract: A virtual desktop system includes a thin client, a virtual desktop managing device, a domain managing device, and a virtualization server. The virtualization server includes at least one virtual machine and virtual desktop. The thin client receives input from a user, and communicates with the virtual desktop managing device by network. The virtual desktop managing device communicates with the domain managing device and virtualization server by network. The domain managing device verifies a domain account of the user according to the inputted information and returns a verification or non-verification to the virtual desktop managing device. The virtual desktop managing device obtains an internet protocol (IP) address of the virtual machine from the virtualization server and returns such IP address to the thin client to enable log-in. A virtual desktop control method is also provided.
