Digital Video Broadcasting-Handheld: A digital television standard designed for reception by handheld and mobile devices. DVB-H pursued mobile broadcast television through a different standards family.
Orthogonal Frequency-Division Multiplexing: A modulation method that sends data over many closely spaced orthogonal subcarriers. Its multipath resilience supports reception by moving DMB receivers.
Digital Audio Broadcasting in South Korea: The adoption and development of DAB-based digital radio services in South Korea. South Korea adapted DAB technology as the foundation for terrestrial DMB.
Digital radio: Radio services in which audio is encoded and transmitted as digital data. DMB carries radio programming alongside television and data.
MediaFLO: A mobile broadcast technology developed by Qualcomm for delivering multimedia to handheld devices. MediaFLO competed with DMB as a dedicated mobile broadcasting system.
Coded Orthogonal Frequency-Division Multiplexing: An OFDM transmission scheme combining error-correcting codes with interleaving. DMB uses this approach to protect broadcast signals against transmission errors.
WorldDAB: An international organization that promotes and coordinates digital radio broadcasting standards and adoption. Its DAB standard provided a technical starting point for T-DMB.
