Digital Terrestrial Multimedia Broadcast

Digital Terrestrial Multimedia Broadcast (DTMB) is China’s digital television standard for terrestrial broadcasting to fixed and mobile receivers. It transmits digital audio, video, and data over broadcast networks.

Time-domain synchronous orthogonal frequency-division multiplexing: A multicarrier transmission method that synchronizes frames and channel estimation using time-domain sequences. DTMB uses this distinctive modulation approach to support robust terrestrial reception.
Digital television: Television transmission in which audio and video are represented and carried as digital data. DTMB is one national system within the broader shift from analog to digital television.
Digital television in China: The development and deployment of digital television services and standards in China. China’s transition to digital broadcasting created the setting for DTMB’s adoption.
DVB-T: A European digital terrestrial television standard based on coded orthogonal frequency-division multiplexing. DVB-T uses a different multicarrier system and frame structure from DTMB.
Digital television broadcasting: The one-to-many transmission of digital television services from broadcast stations to receivers. DTMB is deployed to distribute television programs through terrestrial broadcast networks.
Pseudo-noise sequence: A deterministic sequence with noise-like statistical properties, used in synchronization, ranging, and signal processing. DTMB frame headers use pseudo-noise sequences for synchronization and channel estimation.
Terrestrial television: Television broadcast from ground-based transmitters to receiving antennas, rather than by satellite or cable. DTMB specifies how digital television is delivered through terrestrial transmitters.
Tsinghua University: A research university in Beijing with major contributions to science, engineering, and technology. Researchers at Tsinghua developed the DMB-T proposal that contributed to DTMB.
DVB-T2: A second-generation European digital terrestrial television standard with enhanced capacity and robustness. DVB-T2 is a later-generation alternative with a different technical design.
Mobile television: Television services designed for reception on portable or moving devices. DTMB was designed to support reception by mobile as well as fixed receivers.
