Abstract: A video coding method includes: obtaining a first video file and a second video file that are different; separately decoding the first video file and the second video file to obtain first information of a first image block in the first video file and second information of a second image block in the second video file; obtaining, based on the first information and the second information, difference information indicating a difference between the first information and the second information; and encoding the difference information to obtain encoded data. The difference information may be used to replace an original decoding result in the second video file. It is equivalent to reducing storage resources for video storage and bandwidth for video transmission while ensuring that the complete second video file can be restored.

Abstract: A method and an apparatus for generating comfortable noises so as to improve user experience are disclosed. The method includes: if a received data frame is a noise frame, calculating a corresponding energy attenuation parameter based on the noise frame and a data frame received earlier than the noise frame; and attenuating noise energy based on the energy attenuation parameter to obtain a comfortable noise signal. An apparatus for generating comfortable noise is also provided.

Abstract: A speech signal processing method and a related device thereof are provided. The method may be applied to the audio field and includes: obtaining a user speech signal captured by a sensor; obtaining a corresponding vibration signal when a user generates a speech, where the vibration signal indicates a vibration feature of a body part of the user, and the body part is a part that vibrates correspondingly based on sound-making behavior when the user is making a sound; and obtaining target speech information based on the vibration signal and the user speech signal captured by the sensor. In this application, the vibration signal is used as a basis for speech recognition.
