AVSP Protocol

AVSP is a proprietary serial protocol giving quite full access to EVS video server

resources:

• simultaneous multi-port control from one serial link @115kbps.

• dynamic channel configuration including mixed channel for effect (audio and/or

video)

• playlist management including train (record in progress) with or without fixed

delay

• timeline management including train (record in progress) with or without fixed

delay

• start/stop mode and GPI conditional events

• slow-motion clips

• extended channel and clip status reporting

• ganged channels control

• duplication or move of clips among network EVS video servers

• auto-backup to XFile

• metadata management (1 name + 3 keywords of 12 bytes each)

• This protocol is used for other EVS products interfaced to the server, like

AIRBOX, AIREDIT, EDIT2AIR and by third-party partners for specific

applications.

IPDP Protocol

For more information on how the IP Director application controls the EVS video

server, refer to the IP Director Technical Reference manual and User manual.

LinX API

The LinX Application Programming Interface is an integrated API used to control

the EVS family video servers through IP connection. It is available since Multicam

10.02 version. It is proposed to EVS partners in order to develop applications

interacting with EVS servers.

This API exposes a simplified view of the video server and its functionalities and

hides future underlying changes in the server architecture.

To be as open as possible to potential users, the API implements multiple layers

to isolate all OS dependent parts in lower layers and provide an interface to many

programming language in the upper layers ( C, C++, C#).

Refer to the EVS LinX documentation for more details.
