...DVB-S/S2 modulator featuring multistream technology. The high-speed modulator with up to six multistream inputs and 50-180MHz and/or 950-2150MHz L-band output is ideal for fixed satellite ground stations as well as for SNG vehicles, fly-aways, or any other mobile or portable applications. The product supports DVB-S2 transmissions in variable coding and modulation (VCM) mode to ensure the highest transmission throughput at all times. The new and improved design of the modulator includes features such as:
- Multistream Technology—Users can now aggregate up to six independent transport streams into one satellite carrier in a fully transparent manner. Multistream technology does not modify the original data streams, maintaining the integrity of the original content. Also, fewer modulation devices are required, reducing both operational expenses and capital investments for users
- Transport Stream over IP (TSoverIP)—In addition to the known ASI interface, the updated modulator now offers transport over IP. As a result, users can transport video data via their existing network infrastructure
- Enhanced User Interface—The new, easy to use, web interface (GUI) provides a more powerful and intuitive user experience. This new universal GUI allows for ease–of-access to all features, and a readily customizable interface to meet specific end user requirements and environments
At CommunicAsia 2012, WORK Microwave will display the DVB-S2 IP-Modem SK-IP. Designed for high-speed network layer two and layer three operation, the device uses Generic Stream Encapsulation (GSE) according to TS 102 606 and boasts a multichannel ACM system (OptiACM) to support full integration of ACM capabilities in point-to-point and point-to-multipoint satellite network links. The combination of these two core features provides optimized data throughput in all usage cases and under all types of environmental conditions. Recent additions to the DVB-S2 IP-Modem SK-IP include a data rate of up to 160Mbits/s and an additional power supply for direct connection of BUCs to the modem. The IP-Modem features a powerful new user interface (GUI) plus traffic shaping and cross-layer design for maximum throughput.
A test bench at the WORK Microwave booth will help attendees learn more about the ACM functionality of the IP modem. The interactive test setup will demonstrate how the IP-Modem compensates for disturbances in the satellite link, due to physical conditions—such as humidity and atmospheric precipitation—through real-time adaptation of transmission parameters according to link conditions. The demonstration will include two screens, enabling attendees to observe simulated conditions such as noise, data rate, and type of modulation and to witness the flipping over of the constellation diagram.
