LiveShell X bandwidth requirements

For high quality live streaming an average upload speed of 2Mbps is required. If the network upload speed is around 300kbps broadcasting will be limited to 3~5fps with low quality sound.

This example live stream on YouTube Live (Akihabara Live Camera*) is being broadcast at approx. 2Mbps for both up and down.

*Akihabara Live Camera has been broadcast via LiveShell W. The recommended bit rate is 8Mbps if you want to broadcast 1920 x 1080 60fps, and 4Mbps if you want to broadcast at 1920 x 1080 30fps.

Network requirements for LiveShell X

Please check with the network administrator about communication availability of the following ports.
*Port forwarding is not required.

LiveShell X works normally if it set up in NAT. (Providing that the firewall does not block the connection to the below ports.)

Connection and broadcasting to ustream.tv and Niconico Live require port #1935 to ustream.tv and live.nicovideo.jp to be open.
LiveShell X does not support broadcasting via proxy servers.
You can access Dashboard via a proxy server but the proxy server must allow communication via Websocket or Flash.

Using LiveShell X in a closed local network

Typically LiveShell X is used in an environment that has an internet connection.

But you can also broadcast video and audio using local mode to a closed local network.

LiveShell X needs internet connection to communicate with the Dashboard server for remote control. In local mode LiveShell X will not communicate with any outside networks and as a result of that, Dashboard is unavailable in local mode.

Please see this link for setting up local mode.

Using audio/video input converters

LiveShell X has a HDMI input. Inputs such as SDI and VGA are not supported.

If you want to broadcast video and audio output via SDI or VGA an SDI>HDMI or VGA>HDMI converter is required.

Cerevo does not recommended specific converters and cannot guarantee operation when using a converter. If LiveShell X is damaged by a converter the warranty may be void.

Using HDMI splitters

We recommend that you connect LiveShell X to a HDMI output device (camera, PC, etc.) using a single HDMI cable.

If you use a HDMI Splitter

Cerevo does not recommended specific splitters and cannot guarantee operation when using a splitter. If LiveShell X is damaged by a splitter the warranty may be void.

Using mobile Wi-Fi routers

Mobile Wi-Fi routers that support Wi-Fi connections can connect with LiveShell X.

Mobile Wi-Fi routers are generally more unstable and connect at lower speeds than normal wired or wireless routers, Cerevo recommends using normal wired or wireless routers for high quality live streaming.

Live streaming while teathering

With LiveShell X it is possible to live stream via Wi-Fi tethering to a smart phone or tablet.

*LiveShell X supports 2.4GHz and 5GHz Wi-Fi (IEEE 802.11 a/b/g/n/ac).

How to name devices to individually identify each device

It is possible to register multiple LiveShell series devices to a single Dashboard account and those devices are managed via unique device IDs (to check device ID see this link).

As each device ID is a long string of numbers and letters, naming each device makes it easier to individually identify them.

  1. Access Dashboard and select a target device.
  2. Click [Settings]
  3. Click [Device name setting]
  4. Enter a name and click [Save]
