This work proposes a SingBroad protocol for broadcasting continuous multimedia data over a single channel. Let us consider a channel with bandwidth a·bMbps where a is a positive integer and bMbps is the same as the normal playback rate. The SingBroad protocol first divides a video with time length L into 2a-1-1 equal-length segments and broadcasts these segments over the given single channel. The...
This work presents an Interleaving Slotted-PolyHarmonic-Staircase Broadcasting protocol. Suppose a video is transmitted using y·b bandwidth, where b is the consumption rate under normal playback conditions and y is a positive integer. In the proposed protocol, prior bandwidth (y−1)·b is divided into (h−c+1) channels with bandwidths b/c, b/(c+1),…,b/h, 2⩽c⩽h and ∑i=ch1/i⩽y-1<∑i=ch+11/i, in Harmonic...
