IWMSPublishingPointLimits.PlayerCacheDeliveryRate (Visual Basic .NET)

The PlayerCacheDeliveryRate property specifies and retrieves the maximum content-delivery rate that a player can request.

Syntax

  Integer =
  
  IWMSPublishingPointLimits
  .PlayerCacheDeliveryRate

  IWMSPublishingPointLimits
  .PlayerCacheDeliveryRate = 
  Integer

Property Value

Integer containing the maximum rate at which a player can request that content be delivered to its cache. A value of 1000 means normal playback speed; a value of 1500 means 1.5 times normal speed.

If this property fails, it returns an error number.

Number Description
0x80070057 Integer is an invalid argument.

Remarks

This value determines how much faster than the encoded bit rate the server is allowed to stream content to a player's cache for opportunistic streaming. Opportunistic streaming allows a player to cache additional data whenever the bandwidth of the connection exceeds the encoded bit rate of the on-demand content. This allows the player to minimize the effects of temporary reductions in network throughput. The default value is 5000, meaning content can be delivered at 5 times the encoded bit rate.

Example Code

  Server As WMSServer
    Dim PubPoints As IWMSPublishingPoints
    Dim PubPoint As IWMSPublishingPoint
    Dim Limits As IWMSPublishingPointLimits
    Dim iValue As Integer

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

    ' Retrieve the IWMSPublishingPoints object.
    PubPoints = Server.PublishingPoints

    ' Retrieve information about each publishing point.
    For Each PubPoint In PubPoints

        ' Retrieve the IWMSPublishingPointLimits
        ' object for the publishing point.
        Limits = PubPoint.Limits
        ' Retrieve the limit for the cache delivery rate to clients.
        iValue = Limits.PlayerCacheDeliveryRate
        ' Set the limit for cache delivery to clients.
        Limits.PlayerCacheDeliveryRate = 5000
