Media Servers SL NEO 1000 Series

A Universal Solution for Automated Multi-Channel Ingest to Files for Production, Broadcast and Archive


The ingest solution is a client/server system designed to be scalable. The system can have arbitrary numbers of servers and clients, the configuration of clients and servers is unconstrained allowing for flexibility in deployment and use. 

As a system designed to interoperate with a number of different broadcast technologies, SL NEO 1000 supports real-time multi-channel ingest to a wide range of codecs and file containers including:

  • AVID DNxHD (120, 145, 185, 220 Mbit/s),
  • Panasonic (DVCPRO25, DVCPRO50, DVCProHD),
  • Sony XDCAM IMX (30, 40, 50 Mbit/s), DV25/DVCAM, XDCAM HD 422, HDV, AVCHD, XAVC 
  • MPEG-2 4:2:0, 4:2:2, IPB GOP or I-frames, 
  • MPEG-4 (H.264),
  • Apple Pro Res (HQ, LT, Proxy),
  • File Containers: AVI, MOV, MP4, MXF D-10/OP1A, RAW DV/DIF, MPEG PS/TS, FLV.
Each ingest server SL NEO 1000 Series is capable of recording up to 12 SD or to 8 HD channels simultaneously, with each channel being captured to one or two independent codecs along with a low resolution proxy. Metadata about an ingest is stored in a built-in media-database.  Client applications can be used to add metadata to a live or prerecorded feed.

The system also incorporates an edit-while-capture module that was implemented as a virtual filesystem. This allows editors to start working on a file being captured before the capture is finished. A further advantage of the virtual filesystem is that the same essence can be present within multiple edit-while-capture files without having an additional storage overhead.

Servers can be controlled locally or remotely via LAN/WAN from PC-based client work stations. The embedded Web-Based Interface provide access to the system administrative functions associated with configuring and customizing the system. 

Series 1000 contains a wide spectrum of models with various numbers of input channels, AV signal and TS types (UHD/HD/SD SDI/CVBS/YCRCB, TS over ASI/IP, Analog/AES/SDI Embedded Audio), depending on the model.

Key Features and Benefits

  • Broadcast quality across 24/7 operation;
  • Simultaneous and independent functioning of several recording channels (1...12 for SD, 1...8 for HD, 1 for UHD);
  • Recording to local or networked storage, AVID storage support; 
  • Automated media file export during file recording;
  • Automated recording to files of media materials according to the record-lists from CVBS/SDI/IPTV/WEB sources;
  • Access to the material within seconds after recording starts (chunks mode support);
  • Control of recordings from clients’ PCs using Client Software and via Hot Keys/GPI;
  • Сreation of several recording profiles and instantaneous profile interchange;
  • Layout, editing, import, and export of record-lists for recording channels;
  • IP-streaming for Live Preview, automatic creation low resolution proxy-copies of materials during recording;
  • External Routers control, automated line source change in accordance with the record-list events;
  • VTR device control using RS-422/IEEE1394 server ports/ batch capture mode is used when working with a VTR according to record-lists;
  • VITC Capture for Frame-Accurate Recording from tapes;
  • Configuring and managing the Server System using the Web-based interface.
The functions may change depending on the server’s specific hardware/software configuration.

Additional HD-SDI/HDMI MultiViewer Output

The  SL NEO server may be equipped with additional HD-SDI or HDMI outputs which can be used for monitoring of all server inputs on a HD-SDI monitor or flat panel with HDMI inputs. This technology can be used as an alternative to a set of control monitors when working with the server and allows to reduce costs on the server environment: signal distribution and conversion, monitors and so on. 

MultiViewer output supports up to 12 of server's input channels. Built-in audio mixer allows switching audio output to any of the input audio channels, as well as mixing any number of selected input channels. 

The SL NEO Client Software bundle includes a Graphic Editor that allows positioning on the screen windows for each of the input signals, and besides, adding custom labels, clocks, logos, backgrounds and audio level meters. 

The user can define an arbitrary number of multiscreen compositions and switch them instantaneously by pressing HOT-Keys on the computer keyboard or GPI signals. The MultiViewer output supports HD and SD output in both 16:9 and 4:3 formats and is capable of simultaneous displaying inputs of different formats and standards.

Built-in Software MultiViewer for Client Workstations

The SL NEO servers use encoding and low-speed IP-streaming technology for control of input signals in multi-view mode on a PC monitor with the option of full-screen viewing of a chosen channel with sound.
