Disclosed in the present invention is a nonlinear optical crystal. The chemical formula of the nonlinear optical crystal is MHgGeSe, M being selected from Ba or Sr. The nonlinear optical crystal has no symmetrical center, belongs to an orthorhombic crystal system, and has a space group Ama2. The nonlinear optical crystal is an infrared nonlinear optical crystal, and has the advantages of great nonlinear optical effect, wide light transmitting band, high hardness, good mechanical properties, breakage resistance, deliquescence resistance, easiness in processing and preserving, etc. Also disclosed in the present invention are a method for preparing the nonlinear optical crystal and application thereof.

Nonlinear optical crystal, method for preparing the same and application thereof

Provided is a method for encoding live-streaming data, including: acquiring first state information associated with a current data frame; generating backup state information by backing up the first state information; generating a first encoded data frame by encoding the current data frame based on a first bit rate and the first state information; generating reset state information by resetting the updated first state information based on the backup state information; generating a second encoded data frame by encoding the current data frame based on a second bit rate and the reset state information; and generating a first target data frame corresponding to the current data frame based on the first encoded data frame and the second encoded data frame.

Method for encoding live-streaming data and encoding device

Embodiments of the application can provide a method, a device, and a terminal for controlling a jitter in network communication, belonging to the technical field of communication. The method includes: generating trigger information, where the trigger information is for triggering switching of a jitter control strategy for the network communication, the jitter control strategy includes a first control strategy based on a first cached data amount and a second control strategy based on a second cached data amount, and the first cached data amount is smaller than the second cached data amount; switching the jitter control strategy to a target control strategy in response to the trigger information; and controlling the jitter in the network communication by using the target control strategy, where the target control strategy is the first control strategy or the second control strategy corresponding to the trigger information.
