As a member of CMMB, Newtec has assisted in the construction of the CMMB system with its unique transmission product solutions, earning praise from users for its fast and efficient product services.
In the CMMB transmission system, the products used from Newtec include: NTC/2277 DVB-S modulator, NTC/2137 ASI multiplexer/demultiplexer, and the NTC/2131 fully transparent ASI/DS3 network adapter specifically developed according to the characteristics of the CMMB system. These products have been deployed in CMMB systems in cities such as Beijing, Guangzhou, Shenzhen, and Wuhan, with users reporting stable operation of the equipment.
1. NTC/2277 DVB-S Modulator
Newtec has always focused on the technological research and development and production of DVB modulators. The excellent technical performance of its products and the functional design that closely meets user needs have received widespread acclaim from various users and have been extensively applied both domestically and internationally. Currently, Newtec's DVB modulators hold over 80% of the market share in the domestic market.
2. NTC/2137 ASI Combiner/Splitter
NTC/2137 ASI Combiner/Splitter: This product is specially designed by NEWTEC for single-frequency network transmission and is suitable for various transmission methods. It meets the transparent transmission requirements of single-frequency networks.
The NTC/2137 ASI combiner/splitter solution can transparently transmit CMMB streams to various receiving ends, making it extremely suitable for forwarding CMMB streams through transmission networks (ground SDH networks, optical fiber networks, and satellite networks) to the front end of CMMB single-frequency network systems that require absolutely transparent transmission. This solution combines multiple signals and transmits them over the same optical fiber or satellite carrier, significantly saving bandwidth resources while accommodating different service applications on the same transmission carrier.
Technical Advantages of Newtec Combiner/Splitter Solutions:
—— Complete transparent transmission of digital content: At the receiving end, the original signal can be restored in its entirety, including all original program information, clock information, and bitrate, among others.
——NEWTEC patented technology protects digital content from being accessed by unauthorized users, eliminating concerns about its transmission being intercepted or monitored by any standard DVB devices.
To provide a higher level of security, the built-in Newtec scrambler can also be used to protect the transmission stream for each channel.
- Matrix routing can be used between multiple inputs/outputs. For example, input 1 of the combiner can be sent to other outputs of the splitter as needed by the user.
3. NTC/2131 Fully Transparent ASI/DS3 Network Adapter
NEWTEC has specifically developed the NTC/2131 application for CMMB, launching a fully transparent version that is entirely suitable for CMMB applications, ensuring the transparent transmission of CMMB bitstreams over SDH networks:
NTC/2131/NA.A Network Adapter: Converts CMMB ASI stream into DS-3 signal.
NTC/2131/NB.A Network Adapter: Completely restores DS-3 to CMMB ASI stream transparently.
