“…To reduce the number of streams and alleviate network bandwidth usage on the sender, existing stream merging schemes (Refs. [14], [15], [16], [17], [18], [19], [20], [21], [22], [23], [24], [25]) can be applied. Because these existing schemes assume mainly video-on-demand (VoD) applications, they need to keep the jitter of the data stream delivery as small as possible for smooth video playback.…”
