SERVICE DESCRIPTION LIVEARENA BROADCAST ROOM
LiveArena Broadcast Room automates the production of live video hence mittegating the need of production staff. Based on advanced pattern recognition and AI it enables fully automated production of live TV.
We’ve taken broadcast AI to the next level, embedding never-before-seen artificial intelligence into the LiveArena Broadcast Room. The fully automated suite provides integrated content formats for news, presentations, and talk shows.
Simply select your format, turn on your camera, and watch as the Broadcast Room technology intelligently follows the action. The Broadcast Room evaluates your live stream pixel-by-pixel, analyzing the video input to detect who is speaking and how they are moving, seamlessly tracking the presenter’s motion as he moves and speaks.
2. System Overview
The LiveArena Broadcast Room main system componets are:
Broadcast Room Computer
Systems Overview, a detaild descriptions of the required hardware can be found in the section 3.1.
The Broadcast Room camera should be a 4K enabled camera. For best performance and maintanence the camera should be permanently mounted in the room at a distance of between 4-12 meters from the center of attention.
2.2 Management Console
The Management Console should also be permanently mounted. Reccomended placement is close to the center of attention since it is used to start and stop the broadcast as well as other management tasks performed by the host of the broadcast.
2.3 Data Input
The Data Input or secondary source connector can be used to connect the host (P resenters) computer via HDMI to NDI over ethernet to the Broadcast Room Computer. It is also possible to connect the an external device (e.g. projector or TV) to the source connecter via HDMI in order to show the presenters computer to a audience .
2.4 Audio System
The Audio System consist of two wireless microphones with rechargeable batteries and a charging station. The Audio System is self configuring and communicates with the Broadcast Room Computer over ethetrnet. The Microsophones will automatically be switched on, when removed from the charging station. The charging station can be mounted.
2.5 Broadcast Room Computer
The heart of the Broadcast Room is the computer that receives the feeds from the Camera and Data Input sources. Both inputs are analyzed and encoded into a single broadcasted streamed to the supported streaming platforms (Microsoft Stream and LiveArena Broadcast). The produced and encoded stream is also recorded and stored on a local drive for backup purposes in case of connectivity issues.

3.2 Network Diagram
The Management Console is used to control the the LiveArena Broacast Room. This is where the host inputs the globally unique, 6 digit, PIN-code that authenticates and configures the Broadcast Room. It is also used to choose the production format, Presentation or TalkShow, and to decide the destination of the live stream, Microsoft Stream or LiveArena Broadcast.
During a live broadcast the Management Console displays a low-res preview of the outgoing broadcast.
The Management Console also performes continuous self tests of the Broadcast Room equipment to make sure that the system is fully operational. If errors occur they are presented on the Management Console as well as logged to the LiveArena Broadcast administarion service.
The Management Console start screen where the PIN-code is entered to initiate the Broadcast.
5. Production Formats
LiveArena Broadcast Room features two production formats, Presentation and TalkShow. Presentation is based on the concept of one host with andditional data source consisting of PowerPoint slides, still images or pre-recorded video material. TalkShow is a dalog format with two persons infront of the camera.
The Broadcast Room computer will, during a Presentation run advanced pattern recognition to track the host (Presenter) as the person moves infront of the Camera. As the presenter switches slides the AI of the Broadcast Room will kick in and strart to automatically mix between the Camera source and the Data Source. The person tracking feature mitigates the need of a camera man and makes sure to keep the presenter in center frame of the Camera source. Slide switch detection analyzes the image from the Data Source and intelligently decides which scene to present to the viewers. If there are a lot of details in the image the output will be either a side-by-side (butterfly) with the Presenter and Data Source next to each other or the Data Source in fullscreen. If on the other hand there is less details the Data Source (presentation slides etc.) that source is shown for a brief period of time and primarily cut to full screen shots of the Presenter.
5.1.1 Person tracking
The advanced pattern recognition of the Broadcast Room will evaluate the Camera image pixel-by-pixel to detect the Presenter and how the Presenter is moving. The tracking motion will seamlessly follow the Presenter as he moves infront of the Camera.
5.1.2 Slide switching
Broadcast Room uses advanced algorithms and text analytics to determine when slides or graphics should be shown full-screen, and automatically navigates between the Presenters, full-screen slide view, and side-by-side shots of both the Presenter and the Data Source – always selecting the best and most relevant sources to create a polished and professional production.
The Broadcast Room computer will, during a Talkshow run advanced pattern recognition to track a host and a guest.
If the host is talking the output will be a close up of the host and vice versa as the guest starts talking. During transitions in the conversation or if both persons are talking at the same time the system will switch to a wide shot featuring both.
5.2.1 Person tracking
The advanced pattern recognition of the Broadcast Room will evaluate the Camera image pixel-by-pixel to detect where the host and guest are located and, if applicable, track them as they move. The person tracking feature mitigates the need of a camera man and makes sure to keep the host and guest in center frame of the different scenes
5.2.2 Speach detection
The AI of the Broadcast Room also uses speech detection analyzes on the audio input to intelligently decides which scene to present to the viewers, always selecting the best and most relevant output to create a polished and professional production.
