A method and a stream-pushing client terminal for pushing audio and video based on a WebRTC protocol are provided. The method includes: calling, by a stream-pushing client terminal, an audio interface of a browser to create an audio processing module, and configuring, by the stream-pushing client terminal, a hybrid output unit on the audio processing module; inputting, by the stream-pushing client terminal, source data and additional data to the audio processing module, and generating, by the stream-pushing client terminal, processed data through the hybrid output unit; combining, by the stream-pushing client terminal, the source data and the processed data to generate hybrid sound data; and pushing, by the stream-pushing client terminal, the hybrid sound data to a resource server, to enable a stream-pulling client terminal to obtain the hybrid sound data from the resource server.

An example method performed by a processing system includes receiving a request from a user, wherein the request identifies a plurality of items of source content, and wherein the request indicates that the user would like to generate synthesized content from the plurality of items of source content, retrieving, by the processing system, a plurality of sets of permissions, wherein each set of permissions of the plurality of sets of permissions is associated with one item of source content of the plurality of items of source content, determining, by the processing system, whether the request can be satisfied, based on the plurality of sets of permissions, and automatically generating, by the processing system, the synthesized content using the plurality of items of source content, when the request can be satisfied based on the plurality of sets of permissions.

A digital television including an interface to receive control signals from a remote controller; a screen; and a controller to execute an application related to a first icon within a menu when the controller receives a signal selecting the first icon within the menu from the remote controller, display a content of the executed application related to the first icon on the screen, enter into an edit mode of a second icon within the menu and display a first indicator for deleting the second icon as well as a second indicator for moving the second icon with displaying the content of the executed application related to the first icon in response to selecting an Up-key included in the remote controller, display a message verifying whether or not to delete the second icon from the menu in response to selecting an OK-key included in the remote controller after selecting the first indicator, delete the second icon from the menu and align other icons in a respective order in response to receiving a signal requesting for a deletion of the second icon through the message, and display the aligned other icons on the screen.

Video footage captured by A/V recording and communication devices may be readily uploaded to the cloud and shared with a requesting party, such as a law enforcement agency. When a request is received from a requesting party for video footage, videos meeting the criteria specified by the requesting party may be determined. Consent requests may then be sent to users associated with each of the A/V recording and communication devices that recorded the videos meeting the criteria specified by the requesting party. When user consents to share the videos, the videos may be provided to the requesting party.

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.

Systems and methods are disclosed for detecting and removing traceable identifying audio content from electronic media content. One method includes: receiving, over a network, media content to be broadcast or distributed, the media content including audio data; determining whether the audio data of the media content includes traceable identifying audio content defined by an audio identifier; generating new audio data based on the audio data of the media content when an audio identifier is determined to be include in the audio data; removing audio data from the media content when the audio identifier is determined to be include in the audio data; adding the new audio data to the media content when the audio data is removed from the media content; and broadcasting or distributing the media content having the new audio data to one or more user devices.

Methods, apparatus and systems related to packaging a multimedia content for distribution are described. In one example aspect, a method for performing post-production editing includes receiving one or more footages of an event from at least one user. The method includes constructing, based on information about the event, a script to indicate a structure of multiple temporal units of the one or more footages, and extracting semantic meaning from the one or more footages based on a multimodal analysis comprising at least an audio analysis and a video analysis. The method also includes adding editing instructions to the script based on the structure of the multiple temporal units and the semantic meaning extracted from the one or more footages and performing editing operations based on the editing instructions to generate an edited multimedia content based on the one or more footages.

Disclosed are a television apparatus and a display method. The television apparatus includes a display configured to display an image, a communication interface configured to communicate with a mobile device and one or more servers, and a controller in connection with the display and the communication interface. The controller is configured to receive authentication information from a second server of the one or more servers, display the authentication information on the display of the display apparatus, receive a display request for displaying an item in actual physical size from the second server, and display the item in actual physical size on the display of the television apparatus.
