In some implementations, a user device can be configured to create media messages with automatic titling. For example, a user can create a media messaging project that includes multiple video clips. The video clips can be generated based on video data and/or audio data captured by the user device and/or based on pre-recorded video data and/or audio data obtained from various storage locations. When the user device captures the audio data for a clip, the user device can obtain a speech-to-text transcription of the audio data in near real time and present the transcription data (e.g., text) overlaid on the video data while the video data is being captured or presented by the user device.

A screen recording method includes obtaining operation data of an electronic device and response data generated by the electronic device based on the operation data; obtaining a virtual device image matching the electronic device; and associating the operation data and the response data with the virtual device image according to a pre-determined processing strategy to generate a first video.

A method for changing service within a digital television decoder, the digital decoder including a plurality of tuners, each tuner being capable of receiving a stream of signals including data relating to television services, the method including configuring each tuner for receiving a particular service; restoring, on a screen, a first service corresponding to the service for the reception of which a first tuner has been configured; receiving, via the decoder, a first change of service command with a view to displaying a second service for the reception of which a second tuner has been configured; receiving, via the decoder, a second change of service command with a view to displaying a third service for the reception of which a third tuner has been configured; applying a forced delay before displaying the second service and/or the third service.

There is provided a monitoring camera system including at least one monitoring camera and a recorder connected to the monitoring camera. The monitoring camera captures an image of an area of a monitoring target, detects a motion in a captured video of the area, associates information relating to the motion with the captured video, and transmits the associated result to the recorder. The recorder associates the captured video of the area captured by the monitoring camera and the information relating to the motion with the monitoring camera, and records the associated result. The recorder reproduces the captured video of the area on a monitor recorded in the way that a reproduction speed of the captured video in a section in which the motion is not detected on the monitor is faster than a reproduction speed of the captured video in a section in which the motion is detected, based on the information relating to the motion.

In some embodiments, a method determines a combination of sub-bitstream chunks from a plurality of sub-bitstreams for a video. The combination of sub-bitstream chunks includes a quality measurement. The method exchanges a sub-bitstream chunk in the combination of sub-bitstream chunks with another sub-bitstream chunk from another sub-bitstream in the plurality of sub-bitstreams based on a relationship of a change in bitrate to a change in quality due to the exchanging. The method continues to exchange a sub-bitstream chunk in the combination of sub-bitstream chunks with another sub-bitstream chunk until the quality measurement of the combination of sub-bitstream chunks meets a target quality and outputs the combination of sub-bitstream chunks.

The present invention provides a video sticker processing method and device. The method comprises: performing face recognition and speech recognition on video to be processed separately to obtain face position data when face recognition is successful, and speech recognition text when speech recognition is successful; matching speech recognition text with description text of each sticker in sticker library to obtain a target sticker, and obtaining a target video frame according to speech recognition text; adding target sticker to default position or target position of target video frame; wherein, target position is calculated according to the face position data. The present invention can automatically determine the target sticker and its added position according to the face recognition result and the speech recognition result of the video to be processed, realize the intelligent selection and placement of the target sticker, and improve the processing efficiency of the video sticker.
