Depending on the protocol and the extent of the loss, the client may be able to recover the data with error correction techniques, may interpolate over the missing data, or may suffer a dropout.
Some streaming broadcasters use streaming systems that interfere with the ability to record streams for later playback, either inadvertently through poor choice of streaming protocol or deliberately because they believe it is to their advantage to do so.

WDM Streaming is a kernel-mode solution to the general problem of synchronizing the rendering of large volumes of data in as close to real time as possible in Win98 and Win NT environments.
As data stream transition from the non-kernel mode to the kernel-mode is time consuming, WDM Streaming is moving most data streaming tasks from the non-kernel mode code modules onto the kernel mode drivers or onto hardware, which Streaming also reduces latency.
WDM Streaming also provides a non-kernel filter that acts as a generic proxy on behalf of the kernel mode drivers, to provide a transparent integration between DirectShow and WDM Streaming.The proxy marshals data between the COM-based interfaces of the DirectShow and the kernel’s use of IOCTLs and IRPs.
