The autorun.brs file provides specific instructions to the player for what to do upon startup. For example, an autorun file may instruct the player to display a specific .html file which can be either local to the player or reside on an external website. Alternatively, an autorun file may instruct the player to check a particular URL for updated presentations and/or content and, if new files are available, download them and play them.

Upon bootup, the player searches for certain files. The player’s search follows a prescribed sequence as shown below.

As mentioned in the Player Storage section, the player will search for storage devices in a predefined order.

  1. The player first looks for an autorun.brs file in the root directory of the first storage device it encounters.

    1. If found, autorun.brs is executed.

  2. If an autorun.brs file is not found, the player looks for an autorun.zip file in the same root directory.

    1. If an autorun.zip file is found and it also contains within it an autozip.brs file, the player will unzip the autorun.zip file, in the process overwriting any existing files on the storage device.

    2. The player will then reboot.

If an autorun.zip is not found, the player will query the BSN.cloud provisioning service (often referred to as B-Deploy) to see if the player has previously been provisioned. More details about provisioning will be covered later in this guide.

Both autorun.brs and autozip.brs must be written in BrightScript and be given the specific filenames indicated.

Additional information about these files can be found here.

Below are sample autorun.brs and autozip.brs files for reference.

Sample autorun.brs

 This autorun.brs file instructs the player to display a local HTML file, specifically, index.html:
Sub Main()
    'Create the BrightSign event handler.
    msgPort = CreateObject("roMessagePort")
    
    'Define the screen viewing area.
    r = CreateObject("roRectangle", 0, 0, 1920, 1080)
  
    'Set the URL where the presentation resides. This can be either local or external.
    config = {
      url: "file:///index.html",
    }

    'Create an HTML event since our presentation is an HTML file.
    h = CreateObject("roHtmlWidget", r, config)
    h.SetPort(msgPort)
    sleep(10000)
    h.Show()

    'Event loop to ensure that the script runs indefinitely
    while true
        msg = wait(0, msgPort)
        print "type(msg)=";type(msg)
        if type(msg) = "roHtmlWidgetEvent" then
            eventData = msg.GetData()
            if type(eventData) = "roAssociativeArray" and type(eventData.reason) = "roString" then
                print "reason = ";eventData.reason
                if eventData.reason = "load-error" then
                    print "message = ";eventData.message
                endif
            endif
        endif
    end while

End Sub

Sample autozip.brs

 This autozip.brs file instructs the player to unzip the autorun.zip file:
'name file autorun.zip
' Content update application

Sub Main()
    path$= FindDestPath()
    source$= FindSourcePath()
    package = CreateObject("roBrightPackage", source$+"autorun.zip")
    package.SetPassword("test")
    package.Unpack(path$)
    package = 0
    CreateDirectory(path$+"brightsign-dumps")
    CreateDirectory(path$+"pool")
    CreateDirectory(path$+"feed_cache")
    CreateDirectory(path$+"feedPool")

    DeleteFile(path$+"autozip.brs")
    DeleteFile(source$+"autorun.zip")
    a=RebootSystem()
End Sub

Function FindDestPath()
    if not IsFirmwareValid() then
        return "SD:/"
    end if

    destinationPaths = ["SSD:", "SD:", "USB1:"]
    for each destination in destinationPaths
        if IsMounted(destination) then
            return destination+"/"
        end if
    next
    return "unknown"
End Function

Function FindSourcePath()
    if not IsFirmwareValid() then
        return "SD:/"
    end if

    sourcePaths = ["USB1:", "SD:", "SSD:"]
    for each source in sourcePaths
        if IsMounted(source) and CheckFile(source+"/autorun.zip") then
            return source+"/"
        end if
    next
    return "unknown"
End Function

Function IsMounted(path as String)
    if CreateObject("roStorageHotplug").GetStorageStatus(path).mounted then
        return true
    end if

    return false
End Function

Function IsFirmwareValid()
    di = CreateObject("roDeviceInfo")
    return di.FirmwareIsAtLeast("7.0.60")
End Function

Function CheckFile(path as String)
    file = CreateObject("roReadFile", path)
    if type(file) = "roReadFile" then
        return true
    end if

    return false
End Function

Next, we will look at the various content sources that players are able to utilize.
