Redundant stream alignment in IP datacasting over DVB-H

摘要

A real-time program transmission system and method may receive a signal from a content source, and generate two different data streams. One stream may be of a higher quality than the other. The two streams may then be inserted into time slice frames, such that a single frame carries two portions of data: one corresponding to a first time segment in the program, and a second corresponding to a different time segment in the program. A receiving mobile terminal may buffer the received data, and may use the lower quality data as a backup in the event of a transmission error in the higher quality data.
