IWMSBroadcastPublishingPoint.AllowStreamSplitting (Visual Basic .NET)

The AllowStreamSplitting property specifies and retrieves a Boolean value that indicates whether the stream can be split. A cache proxy device can split a stream to minimize network bandwidth. A cache proxy device splits a broadcast stream by making a single connection to an upstream server and then copying the incoming packets to multiple downstream clients.

Syntax

  BroadcastPublishingPoint
  .AllowStreamSplitting
  
  =
  
  Boolean
  
  Boolean
  
  =
  
  BroadcastPublishingPoint
  .AllowStreamSplitting

Property Value

A Boolean that indicates whether the stream can be split.

If this property fails, it returns an error number.

Number Description
0xC00D145AL The publishing point has already been removed.

Remarks

The default value is True. This allows the proxy server to split a broadcast so that, regardless of how many clients are connected to the proxy to receive the broadcast, there is only one connection from the proxy server to the origin server. If you set this value to False, there must be one connection between the proxy and the origin server for each client connected to the proxy server.

Example Code

Imports Microsoft.WindowsMediaServices.Interop
Imports System.Runtime.InteropServices

Private Sub DisableStreamSplitting()

    ' Declare variables.
    Dim Server As WMSServer
    Dim PubPoints As IWMSPublishingPoints
    Dim PubPoint As IWMSPublishingPoint
    Dim BCPubPoint As IWMSBroadcastPublishingPoint
    Dim bVal As Boolean
    Dim i As Integer

Try
    ' Create the WMSServer object.
    Server = New WMSServer()

    ' Retrieve the IWMSPublishingPoints object.
    PubPoints = Server.PublishingPoints

    ' Retrieve each publishing point and retrieve the
    ' IWMSBroadcastPublishingPoint object.
    For i = 0 To Server.PublishingPoints.Count – 1

        PubPoint = PubPoints.Item(i)
        If PubPoint.Type = WMS_PUBLISHING_POINT_TYPE.WMS_PUBLISHING_POINT_TYPE_BROADCAST Then
            BCPubPoint = PubPoint
            Exit For
        End If
    Next i

    ' Retrieve a Boolean value indicating whether the
    ' stream can be split.
    bVal = BCPubPoint.AllowStreamSplitting

    ' Set the publishing point to disallow stream splitting.
    BCPubPoint.AllowStreamSplitting = False
