An online conferencing system that provides an automatic mechanism to broadcast an online conference. A video gathering component gathers video streams for each of at least some of the current participants in the online conference. A broadcast start triggering component allows one or more of the participants to trigger operation of a broadcasting component. The broadcast component that, when triggered, causes a resulting video stream comprising at least a composite of at least some of the gathered video streams to be published to a plurality of viewers. In some embodiments, pre-processing of the video streams to create the resulting video stream also occurs. Such pre-processing could include, for instance, composing a stream from multiple video streams, altering one or more of the video streams, applying augmented reality to the video stream, and so forth.

Methods and systems for providing a video stream along with a slow motion video showing a particular event depicted in the video stream are described herein. The method includes generating a first video stream and generating a second video stream, which is a slow motion video stream, from the first video stream by modifying a playback speed of the first video stream. The method includes monitoring content of the first video stream to identify an event trigger of a predefined set of event triggers. Each event trigger indicates a presence in the first video stream of an event that is to be generated for display using the second video stream. The method includes determining, based on the identifying of the event trigger, to transmit the second video stream along with the first video stream, and simultaneously transmitting both the first video stream and the second video stream.

An encoding system includes a plurality of encoders each of which encodes a signal having continuity supplied from a corresponding one of a plurality of information sources and generates a packet containing a portion of the encoded signal. Each encoder is classified as a first encoder which encodes the signal, or a second encoder which transfers the packet from at least one of the first encoders, to a communication network and which, when the first encoder has failed, replaces the failed first encoder. When a failure occurs in either one of the first and second encoders for any of the signals, the other one of the encoders detects the occurrence of the failure, reallocates the encoders other than the failed encoder so as to act as the first encoder or second encoder for respective ones of the information sources, and notifies each encoder of the result of the reallocation.

Systems and methods are provided herein relating to adaptive video streaming. Time-to-offset mapping associated with a set of video blocks can be broken up into chunks. A client can download a first set of seek index chunks and use the first set of seek index chunks to select a stream. Seek index chunks within remaining sets of seek index chunks can be ranked for relevance based on client capabilities. A subset of remaining sets of seeks index chunks can be downloaded based on the rankings and client capabilities during streaming. Chunked time-to-offset mapping can facilitate faster startup when playing streamed video.

Methods, systems, and computer readable media can be operable to reduce the number of video streams or increase the quality of delivered video with the same number of video streams in a multiple bitrate video encoding. Multiple video resolutions and/or frame rates can be combined into a single stream. In embodiments, optimal segments from a plurality of input streams can be selected for inclusion in an output stream based upon a range of acceptable quantization parameter values for the output stream and a quality characteristic associated with the optimal input stream.

A video processing method includes: receiving multiple channels of video images individually sent from multiple mobile terminals; displaying the multiple channels of video images; acquiring a selection instruction according to a user input, the selection instruction carrying an identifier of a target video image, the target video image including at least one of the multiple channels of video images; and transmitting the target video image to a target terminal. According to embodiments of the disclosure, any desirable video image can be selected from the multiple channels of video images being displayed as the target video image for live broadcasting.

A method and a device for forming a common transport datastream from several mobile-digital television signal datastreams and a common stationary-digital television signal datastream. A constant number of data units of respectively-constant size in every successive time interval with constant cycle duration for the transmission of every individual datastream is determined. A data structure is specified for the common datastream with successive sequences in each case of a constant number of data units with respectively-identical positions for data units of the stationary-digital television signal and respectively-identical positions for data units of the mobile-digital television signal. Data units of each of the datastreams of the mobile-digital television signal are transmitted in each case in associated, identical positions of at least one successive sequence, and define the individual positions of the data structure of the common datastream with data units of the respectively associated datastreams.
