Nagasoft Caster X1 Broadcast / Streaming Tablet

In the first scenario, several cameras are to be integrated into a video broadcast in the school environment, e.g. in physics lessons. The caster can accept six video sources simultaneously: 2 x HDMI, 2 x SDI, 1 x external video stream and up to 4 streams from PTZ cameras, which can also be controlled via the caster. The lecturer can switch between the 6 video sources via touch control, select pleasant transition effects or picture-in-picture applications if required, fade in subtitles or images. All input signals and the program stream can be conveniently stored internally on the caster and later archived to external storage via the USB interface or via ftp upload. Recording is done in a memory-saving way as compressed H264 4:2:0 video in MP4 format. In addition, existing videos can be played back by the caster. The teacher thus has a wide range of video sources and functions at his disposal for explaining the learning material.

The output signal of the caster is fed into the instructor's existing notebook via an HDMI-USB dongle, e.g. the Atomos Connect. Learning platforms recognize the Connect as a video source without installing a driver, comparable to a webcam.

Some learning platforms restrict the video bandwidths, so that only jerky videos in poor quality arrive at the students from the full HD recordings. In this case, the output signal of the caster can be streamed to a video platform such as Vimeo, and at the same time the teacher selects "Video sharing of an external stream" in the LMS, so that all students can now enjoy the full image quality.

In the second scenario, a lecture is to be made available in a lecture hall of a university to present participants and to students via live stream and as video on demand.

The caster is integrated into the existing infrastructure: The audio signal from the lecturer's microphone is fed into the caster via the XLR input and output to the existing speaker system via XLR output. The lecturer's notebook with the PowerPoint presentation is connected to the X1 via HDMI and output to the projector in the lecture hall via HDMI-out. Additional HDMI, SDI or PTZ cameras or an external video stream can be integrated into the workflow via the existing interfaces of the caster. All video signals can be stored in the caster and also played back if required.

The Caster X1 can output multiple streams in parallel, both to well-known video platforms and to RTMP or SRT servers. Archiving of the lecture is possible directly at the caster, with later output to an external USB storage or via ftp upload to the university server. Alternatively, the video stream can be routed and archived directly to servers at the university with a static IP address.

Further applications in the educational sector:
Of course, in cooperation with an HDMI-USB dongle (Atomos Connect), the Caster X1 can be used driverless as a video source for all communication platforms such as MS Teams or Zoom, allowing all functions from switching multiple video signals, recording and playing back videos, and input and output of video streams even in a classic video conference. The built-in 4G module allows a mobile use of the caster outside the LAN/WLAN infrastructure, while the caster remains protected in the aluminum hard case during transport. With an additional NDI license it is possible to integrate the caster into existing NDI workflows: The NDI function for the Caster X1 currently supports a 4-channel input as well as 6-channel output (5 signals + PGM). Encoding is up to 1080p300fps, decoding 1080p120fps.

- 11.6'' HD touch screen display
- 6 input channels (2x SDI, 2X HDMI, NET, DDR)
- 2 XLR/TRS audio inputs / outputs
- Live+ connection
- A9 processor
- 3GB memory
- 256 GB SSD
- WIFI LAN, Gigabit LAN and 4G module integrated
- multi-channel recording
- live streaming with multiple bitrates
- built-in audio mixer

The Caster X1 is a tool with many features, such as multi-channel switching, 6-channel recording, streaming, audio mixing, special effects visualization and signal monitoring. It also has a built-in Ethernet module, a WIFI module and a 4G module for sim cards, making it ready for all conceivable webcast scenarios.

Up to six video signals in different resolutions (2 x SDI, 2 x HDMI, 1 x network stream and 1 x from internal storage) can be connected simultaneously.
With the paid NDIHX license it is possible to integrate the caster into the NDI workflow and make live productions even more efficient. NDI is now the most widely used IP technology on the market.

Multi-platform live streaming
With just one click, the program stream can be directly streamed to different platforms such as Mudu, AndLive, Facebook, YouTube, Vimeo as well as RTMP or SRT compatible servers without the need for a PC. Depending on the available bandwidth, multiple streams can be transmitted simultaneously. Using a QR code, you can connect your smartphone to the caster without being on the same WLAN. The Nagasoft smartphone app facilitates text input on the device, so you can easily enter or copy even long ULRs.

NET input
An external RTMP/RTSP stream can be fed into the caster via the NET input and is available as a video source.

PTZ Control
The caster supports control of up to 4 IP PTZ cameras, which can be used as additional video sources (as RTSP stream) simultaneously. Functions such as Zoom, focus, iris, saved viewing angles as well as 8 different directions can be operated. Supports ONVIF, VISCA over IP as well as NDI protocol and powers connected PTZ cameras via PoE (Power over Ethernet). The Onvif Auto Discovery function allows convenient integration of new PTZ cameras at the touch of a button.

Video recording
The caster can record up to 6 video signals as compressed H264 4:2:0 video in MP4 format (SDI-1/2, HDMI-1/2, 1 x external network stream, 1 x program). The video quality of the recordings can be selected variably from 1 up to 25 Mbps, audio in fixed steps from 64 to 320 Kbps.
External media can be connected via the USB port to import or export videos. In addition, ftp (file transfer protocol) allows the transfer of stored videos to external servers.

Network support
With Ethernet, WiFi and a 4G module (for sim cards) all requirements for live broadcasts are covered.

No-Delay Switching / Transition Effects
No-delay switching of the six video signals is done comfortably via the touch display. Simply by touching the respective video channel. Transition effects with adjustable transition duration enable a harmonic cut when changing the video source.

Picture in picture
The caster allows the display of 10 different picture-in-picture effects, which can be moved easily by touch input. Up to 4 different video signals can be displayed simultaneously in one picture.

XLR inputs and outputs
In addition to the video inputs, two microphones can be connected via XLR connectors. A selectable audio delay allows synchronization with video signals. A headphone jack and two XLR outputs allow professional monitoring and audio output to external devices.

Audio Mixer Function
The integrated audio mixer allows the input and output volume of the audio signal from each source to be adjusted.

Scoreboard Function
With a large number of "scoreboard" templates, the scores of live sport events such as basketball, soccer, table tennis, badminton or volleyball can be directly faded into the stream.

Character Generator (CG) Fade In
With the Character Generator up to 12 preset or imported images in jpg/png format can be directly inserted and freely positioned.

Live+ connectivity
Thanks to the Naga NDDIP protocol, front-end devices such as smartphones and encoders can be wirelessly integrated instantly by scanning a QR code or entering a numeric code.

Professional interface
A professional and intuitive user interface makes live streaming easy and effective. Optionally, a mouse and keyboard can be connected via the USB port.

Firmware updates
The manufacturer is constantly developing the Caster X1. When connected to the Internet, it checks for firmware updates and displays this in the menu. You can find out about the latest developments and then decide if you want to download an update.
