Abstract: An interprocess communication (IPC) method and an IPC system for transmit communication data from a first process to a second process, where the method includes performing initialization configuration on the first process and the second process, including creating first memory space in shared memory space, selecting a communication manner based on a length of the communication data and a value of a threshold, where the threshold is a size of the first memory space, performing interprocess data exchange in the selected communication manner, selecting a memory sharing manner for communication when the length of the communication data is less than the threshold, and selecting a data file manner for communication when the length of the communication data reaches or exceeds the threshold.

Abstract: Embodiments of the present disclosure provide a 360-degree panoramic video playing method, an apparatus, and a system. The method includes: receiving, by a video player, a search instruction, and displaying, according to the search instruction, locating information of a 360-degree panoramic video, where the locating information includes descriptive information of playing content in multiple angle ranges of the 360-degree panoramic video, and the descriptive information is used for determining the playing content in the multiple angle ranges; and receiving a switching instruction, and switching a playing angle range of the 360-degree panoramic video from an angle range of current playing content to a first angle range according to the switching instruction, where the first angle range is an angle range selected by a user from the multiple angle ranges.

Abstract: Application discloses a picture encoding method and a terminal. In the method, a terminal divides the plurality of pictures into N groups, wherein the dividing is based on reference information of each of a plurality of pictures. The terminal encodes the N groups of pictures, where the following steps are performed on each one of the N groups of pictures: selecting a first picture from a target group according to a preset rule, and encoding the first picture, where the first picture is a picture first encoded in the target group, and the target group is any one of the N groups of pictures; selecting a reference picture for a second picture from the target group, where the second picture is a picture in the target group other than the first picture; and performing motion estimation on the second picture by using the reference picture, to encode the second picture.

Abstract: This application discloses a method and an apparatus for lifting video resolution, where an initial magnified signal obtained by performing upsampling on an original signal is decomposed into two parts, that is, a first signal and a second signal by means of forward wavelet transform, where the first signal and the original signal have the same volume, and high-frequency information in the original signal is preserved; then the first signal is enhanced, so that enhancement on the first signal is transferred to the second signal by performing inverse wavelet transform on the second signal and the enhanced first signal, to compensate high frequency loss in the second signal, that is, high-frequency information of an entire final magnified signal obtained through inverse wavelet transform is compensated relative to the initial magnified signal, so that a magnified image corresponding to the final magnified signal can better preserve high-frequency information of an original image, vagueness of the magnified imag
