You can modify the default buffer sizes associated with incoming audio/video streams. Increasing the buffer can help improve the performance of high-bitrate video streams or audio/video that is being streamed over a slow network. Visit www.DunnVision.com/iptv for more tips.Note that increasing the buffer size will also increase the playback delay (latency) when the stream begins, but decreasing the default buffer size will not shorten it.Once streaming data comes into the main buffer, it is immediately split into the audio and video buffers. The default size of the main buffer is 1.5MB for HD models, 3MB for XD models, and 6MB for 4K models.
