Complete ISDB-T Transmission System for Digital TV Networks
DIGICAST provides a complete ISDB-T Broadcasting Solution designed for television operators, government broadcasters, network operators, and system integrators deploying digital terrestrial television networks.
The solution integrates satellite reception, video encoding, multiplexing, scrambling, ISDB-T modulation, transmission, and wireless coverage into a unified digital TV broadcasting platform. It enables broadcasters to deliver high-quality television services to households, communities, cities, and nationwide audiences through the ISDB-T terrestrial broadcasting standard.
This solution is widely used in South America, Japan, the Philippines, and countries adopting ISDB-Tb (ISDB-T International) for digital terrestrial television deployment.
What is ISDB-T?
ISDB-T (Integrated Services Digital Broadcasting – Terrestrial) is a digital terrestrial television broadcasting standard originally developed in Japan.
The international version, known as ISDB-Tb (Brazilian ISDB-T) or SBTVD, has been adopted by many countries throughout Latin America and other regions.
Compared with analog television broadcasting, ISDB-T provides:
Higher Picture Quality
HD Television Services
Mobile TV Reception
Better Spectrum Efficiency
Improved Signal Robustness
Emergency Warning Broadcast Capability
Multi-Program Broadcasting
Today, ISDB-T is one of the major digital terrestrial television standards worldwide, alongside DVB-T/T2 and ATSC.
Advantages of ISDB-T Technology
Robust Signal Reception
ISDB-T uses BST-OFDM (Band Segmented Transmission OFDM) technology, providing excellent resistance to:
Multipath Interference
Urban Reflections
Mountainous Terrain Challenges
Mobile Reception Conditions
This makes ISDB-T particularly suitable for challenging geographical environments.
Simultaneous Fixed and Mobile Reception
One unique feature of ISDB-T is One-Seg Broadcasting.
Broadcasters can simultaneously transmit:
HD Television Services
Mobile TV Services
Portable Receiver Services
within the same RF channel.
ISDB-T Modulation
The multiplexed transport stream is fed into the DMB-2408 ISDB-T Modulator.
