Technical requirements of our online streams

Test beforehand

If you’d like to run a test before the live stream to see if you meet the technical requirements, start one of the videos in the Mediathek. If a video plays, the technical requirements for the live stream should be in place.


A broadband Internet connection from DSL and higher is a basic requirement. With reception via mobile communications the LTE standard should be at least 3G or higher.
The video will be offered in various transmission qualities: From Low (240p) for lower bandwidths up to High Definition (1080p, Full-HD).
No downloads should be made in the background during the transmission and no other applications should be open.
With access via WiFi the Internet speed depends, among other things, on the distance to the access point/WiFi router. Changing its position can improve the connection quality here.
With DSL/cable connections, the bandwidth confirmed by the provider can fluctuate, which also applies with mobile reception when out and about.

Keep your operating system and programmes as up-to-date as possible.

Ensure, for example, that you use a browser that is as up-to-date as possible. Internet Explorer from Microsoft, for instance, is no longer further developed. In this case, we recommend installing the Microsoft Edge Browser as its successor.

The currently popular browser types, such as Google Chrome, Edge Chromium (IE successor), Firefox or Safari, support smooth video playing.

Streaming technology and player

The transmission is made as an Adaptive HTTP Live Streaming (HLS) in an HTML5 Player. This means that the video quality largely adjusts to the bandwidth provided. The transmission at first starts in the lowest quality for the lowest bandwidth. The Internet connection allows a higher data rate, so the video quickly adjusts itself with the best possible quality. The HTML5 Player allows the video to be played in almost all browser versions, operating systems and devices.

Browser versions with PC and Mac

The HTML5 Player is optimised for the standard browser types, Chrome, Firefox or Safari. Along with the automatic video quality adjustment according to the measured bandwidth, you can also specify the bandwidth you want in the bottom bar with the player controls. This is recommended in cases where the bandwidth is prone to constant fluctuations, which can result in continuous quality fluctuations. In this case a lower bandwidth should be selected, which can then be consistently delivered.

Stream for iOS (iPad/iPhone)

Mobile devices with iOS, such as iPad or iPhone, as well as all standard Android devices, are also configured for playing HLS streams. With the playback functions they behave differently and in places also revert to their own player. The quality adjustment occurs automatically here. On newer generation devices, the quality during the reception on the player can also be selected manually.

Please note: Some devices start the live stream in mute mode, which means that the user must switch on the audio on the player himself.


Adobe Flash Player

As at the end of 2020 Adobe officially stopped supporting the Flash Player technology, live streams can no longer be played via this application.
Some outdated browsers (e.g. earlier Internet Explorer versions) can only play live streams with the Adobe Flash Player as a plugin via our player. An update or reinstallation with an up-to-date browser version is urgently recommended due to security issues. Flash is no longer required, and if in doubt, should be uninstalled.


You can’t see a stream

Clear your browser’s cache. If you are using a Windows computer, press the Ctrl + F5 keys for this. If you have a Mac PC, press the Cmd (Apple) + shift + R keys. Check the Internet connection and the available bandwidth if required.

The transmission is intermittent, the stream is not fluid.

Depending on the computing processor’s capacity or the Internet connection’s bandwidth, there may be quality losses and drop-outs. Close all other programmes and windows that you don’t need at the moment to reduce the load on your computer and connection. Ensure that no other videos are playing at the same time (possibly in the background) and that no data transfers are underway. Reload the page. Open the live stream via an alternative browser (Firefox, Google Chrome, Edge Chromium on Windows) and check that the problem has been removed.

The transmission starts without audio

Check if mute is activated on the device, browser and player.
Begin the test with the video player and check the speaker icon here in the control bar, as well as the speaker control setting. Some browsers influence the video player with the effect that videos in the basic setting are started in mute mode.

Some browsers also offer the option of switching to mute in the top bar. Check the speaker icon in the browser bar above the website to see if the audio is switched to mute. Lastly, the speaker functions on the computer itself should also be checked.

Laptop to TV connection

1. Via HDMI

Newer laptops often have a DisplayPort or an HDMI output. With a DisplayPort you require a suitable DisplayPort to an HDMI adapter and a sufficiently long HDMI cable. First, connect the cable with the TV via a free HDMI input. Then switch the TV’s input to the selected HDMI input. Then connect the laptop with the HDMI cable. The laptop then transfers the display to the TV, usually automatically. If the display does not appear or the video window on the laptop screen is not visible, the laptop display must be switched off. For this the FN key (Function) and monitor key (F7) must be pressed at the same time. Via the selection menu then choose “Output to external monitor” or “Second screen only”.

The audio is also transferred from the laptop to the television via the HDMI output. If the audio is to be provided via the laptop’s headphones output, the output on the laptop must be switched to HDMI in the control panel → Sound (Windows).

2. Via VGA or DVI connection

The connection can also be made via a VGA or DVI connection. All you need here is a VGA or DVI connecting cable. Connect the cable to the laptop’s VGA or DVI output and to the television’s VGA or DVI input. The television is set to PC (RGB/VGA) in the “Input” menu.

The FN key (Function) and monitor key (F2) must be pressed at the same time on the laptop so the monitor picture is displayed on the laptop.

Laptop stereo system connection

Please use a mini jack-cinch cable for this. The laptop is connected via the headphones output with a mini jack. On the stereo system end connect the two cinch connectors to AUX or TV. Ensure the audio output on the laptop is on. The icon in the Windows task bar must not be crossed out. Also check the set speaker level in the sound mixer and correct if required.

If there is no audio output, check the audio output settings in the control panel → Sound. Select the headphones output.

Smart TV

This is one of the new flat-screen TVs with Internet functionality and built-in browser. You can also watch the live stream via these devices. For this, enter the URL via the remote control or a connected keyboard.

Internet set-top boxes/media hubs

E.g. Sony Google TV, Apple TV, Samsung HomeSync etc.

Staatsoper.TV can also be watched via Internet set-top boxes. To do so, connect the device as per the operating instructions via HDMI to your TV set. Check the existing connection with your Internet line. Via the browser you can also watch the live stream with these devices. For this, enter the URL via the enclosed remote control or a connected keyboard.
