Overview

The AirSpeed 5000 API is a TCP/IP socket based protocol used to control and query the AirSpeed 5000 server. The commands

are sent and received using XML (Extensible Markup Language) formatting.

The following items apply:

• TCP/IP available ports (59451-59456) (max of 10 connections per port)

• XML Info: <?xml version="1.0" encoding="utf-8"?>.

• Only one XML command may be sent at a time.

• The major XML commands are formatted as tags “elements”.

• Many of the “element” commands have corresponding “attribute” data.

• All XML references to “TC” are the formatted STRING Time Code (HH:MM:SS:FF) (; if Drop Frame). Most attribute

type of “TC” will also allow the same attribute name with ‘i’ preceding it as an INT representation of the Time Code

“iTC”.

For example, “StartTime=TC” will also allow “iStartTime=iTC” represented as an INT.

The “TC” STRING will be searched for first, and if found, the “iTC” should not be sent. It will be ignored.

• There are three command categories (Configuration, Transport and Database).

• STANDARD is the video standard name. Valid names are:

SD_NTSC_4x3_29_970

SD_PAL_4x3_25_000

HD_1920x1080i_29_970

HD_1920x1080i_25_000

HD_1280x720p_59_940

HD_1280x720p_50_000

Note: All references to VITC also pertain to ancillary time code (ATC) as well.

Channel Control and Command Basics

Controlling an AirSpeed 5000 server via API begins with establishing a connection to the server. The available connection ports

are 59451 – 59456 for channels 1-6 respectively. There can be up to 5 separate connections per port. Multiple connections on the

same port will run synchronously, with only one command processed at a time.

If no data is received on the AirSpeed 5000 server for 60 seconds, then the connection will automatically be closed by the

AirSpeed 5000 server.

Each connection port (59451-59456) will default to a corresponding channel number (1-6). Only ports with corresponding

channels that have hardware connected will be activated.

Note: Some Transport commands such as Play Cue, and Record Cue take longer to process than Status commands.

Formatting

All commands are formatted using XML data packets with the following major tags.

<?xml version="1.0" encoding="utf-8"?>

<AMS><Configuration></Configuration></AMS> Configuration commands

<AMS><TransportControl></TransportControl></AMS> Transport Control commands

<AMS><DatabaseControl></DatabaseControl></AMS> Database Commands

Note: The terminating XML tag “</AMS>” will not be followed by a NULL.

Note: The client can only send one of the major tags at any one time.

Response

All XML commands will respond when the command is completed with the following:

<AMS><Reply Status=”STATUS” Msg=”MESSAGE” ErrNum=”N” /></AMS> Message response

The STRING attribute “Status” is the Reply Status

OK – No error

ERROR – Error Occured

WARNING – Warning

The STRING attribute “Msg” contains the warning or error message. This attribute will not exist if the “Status” = “OK”.

The INT attribute “ErrNum” contains an error value, along with the description of the error in the “Status” attribute. The

attribute “ErrNum” will not exist if the “Status” = “OK”

1 – Command Error

2 – System Error

3 – XML format error

4 – System BUSY

Note: Many commands will send additional tagged information along with the OK response

AirSpeed 5000 API Guide Page 3

Configuration Commands

The Airspeed 5000 API provides several convenience commands for requesting configuration information from the AirSpeed

5000. These commands are defined as the major tag <Configuration> and are typically sent during the initialization sequence, but

may be sent at any time.

AirSpeed 5000 API Guide Page 4
