The low-latency extension was introduced in DVB-SH (digital video broadcast-satellite to handheld) to permit the transmission of latency-sensitive data in S-band Mobile Interactive Multimedia (S-MIM) such as signaling and acknowledgements alongside the latency-insensitive data such as broadcast streams. This enables existing receivers to still receive the latency-insensitive data. This compatibility to existing receivers was achieved by exploiting a periodicity in the interleaved data.
