- Handheld TV is based on CMMB (China Mobile Multimedia Broadcasting
- CMMB is the English China Mobile Multimedia Broadcasting (
- CMMB
- (1) It can provide digital radio and television programs, comprehensive information and emergency broadcast services, and achieve seamless and coordinated coverage of satellite transmission and ground networks, and support public services.
- (2) Support mobile phones, PDAs, MP3, MP4, digital cameras, notebook computers, and small receiving terminals on cars, trains, ships, and airplanes to receive multimedia services such as video, audio, and data.
- (3) Adopting mobile multimedia broadcasting and television technology with independent intellectual property rights, the system can be operated, maintained, and managed, with broadcast and two-way service functions, and can be gradually expanded according to operational requirements.
- (4) Support the combined central and local operation system, with a cryptographic authorization control management system, support for unified standards and unified operations, and support for national roaming of users.
- (5) The system is safe and reliable, with

- IF101, the world's first CMMB standard channel demodulation chip developed by Chuangyi Video, has achieved performance indicators such as sensitivity, power consumption, volume, and cost, and surpassed commercial requirements. Mass production is now possible. At the same time, based on the CMMB chip and its system solutions, the company is stepping up the technical integration and design work of watching TV on mobile electronic devices such as mobile phones, PMP, MP4, GPS and other small-screen handheld electronic devices with handheld consumer electronics companies, and cooperate with Network operation, providing high-quality mobile TV services for the 2008 Beijing Olympics.
- CMMB (STiMi) is a mobile multimedia broadcasting system standard developed by China [standard numbers: CMMB GY / T 220.1 / 2006, GY / T 220.2 / 2006]. CMG2000 is an integrated CMMB signal source test system, which fully complies with China Mobile Multimedia Broadcasting Standard CMMB. The RF part uses a high-performance RF frequency conversion module, and the supported frequency range is: 50MHz ~ 870MHz (step: 1Hz). CMG2000 is a flexible solution that can provide high-quality real-time modulated test signals for CMMB chip companies, Tuner R & D companies, portable receiving terminals and mobile phone receiving terminals.
