Abstract

A system and method is provided for minimizing delay time for controlling media content capture during live video broadcast production. The system includes a video production receiver that receives media content streams from one or more cameras that includes live media content captured by the cameras and encoded in a first encoding format. Moreover, a multi-view interface displays the media content and a video production controller generates control instructions based on inputs to the interface to change operation of the cameras capturing the respective media content. A camera controller is included that transmits the generated control instructions to the cameras to change the operation for capturing the respective media content. Moreover, the video production controls production of a live video stream for video broadcast production using media content that is captured from the cameras and that is encoded in a second encoding format different than the first encoding format.

Dependent claims

A system for controlling media content capture for live video broadcast production, the system comprising:

a remote media production center including a remote production switcher configured to:
generate a media content capture operation to control capture of original media content at a live event location by a media content capture device, and
transmit the media content capture operation to the media content capture device to modify a content capture operation of the original media content at the live event location;
a media broadcast production system configured to receive a plurality of encoded broadcast media streams from a broadcast production encoder communicatively coupled to the media content capture device, respectively, and to produce a broadcast production video stream by applying broadcast production commands to the received and encoded broadcast media streams, such that the broadcast production video stream is configured to be displayed on an end user device;
wherein the media broadcast production system is configured to align the plurality of encoded broadcast production video streams based on timestamps included in a production control sequence in the broadcast production commands to generate a video broadcast production without requiring any additional video production processing of the broadcast production video stream at the remote media production center;
wherein the media content capture device captures the original media content at the live event location during a first time;
wherein the remote production switcher transmits the media content capture operation to the media content capture device in a second time subsequent to the first time;
and
wherein the media broadcast production system receives the plurality of encoded broadcast media streams from the broadcast production encoder in a third time that is subsequent to the second time, such that the media broadcast production system configures the encoded plurality of broadcast media streams for broadcast production as the broadcast production video stream.
