VATek Gen-3 modulator chips bring advance features to new tier of DTV headends
Sponsored content

Vision Advance Technology has introduced the Gen-3 Platform to the market. VATek took years of dedication to bring the new series to reality. The Gen-3 portfolio includes two Super Enmoder chips (B3+ & B3) and a brand new Super Modulator (A3). The new platform is designed to exceed the expectation of modulator makers by offering technologies and features that previously could only be implemented with FPGAs. This will be the first non-FPGA chip to support DVB-T2 (base 1.3.1) modulation.

Gen-3 Super Enmoder can support up to seven different digital TV standards, and featuring AVC + MPEG-2 dual format encoder. By incorporating key modulation capabilities and media processing performance advancements, the Gen-3 Super Enmoders are designed to transform headend products into ultimate broadcast devices, which can work and deliver high quality TV program to every digital TV in different standards. That helps headend manufactures to expand the market worldwide.

Gen-3 Super Modulator (A3) has new architectures, engineered to result in significant improvements over the Gen-1 modulator. A newly added stream engine that can work as transport stream regulator that can implement PID filtering, regulate transport stream and insert customized PSI/SI info into media stream. A3 can support any video encoder without MUX units. A3 modulator is also equipped with VATek's latest modulator engine, bringing more DTV standards including ISDB-T & DVB-T2 to the chip. It allows manufactures to design UHD (4K) DVB-T2 headend product with ease.

VATek will also release new firmware platform to all series of products. The new platform is engineered to deliver efficiency and design flexibility. The update allows each VATek product to share the same developing tools and control logic. Several features and function upgrades will be found in the new firmware as well. The most significant improvement will be the control method. A register-like control mechanism will be introduced to replace the current gateway control system. R2 control logic will be also available in the new firmware platform, allowing every VATek modulator & Enmoder chip to control R2 RF chip automatically. Developers no longer need to build R2 driver, and will still be able to access the RF chip, and users can even conduct IQ balance calibration with a few mouse clicks. VATek also has made a major upgrade to extend TS API, and with new auto data repeat features, the chip now can automatically mux the repeated PSI/SI data into the stream reduce system loading dramatically. VATek will provide paid PSI/SI design service for customers who use the new platform. They can purchase the authorization key to enable the PSI/SI function.

The VATek Gen-3 series is available this June and is expected to be found in consumer devices in the fourth quarter of 2018. Visit VATek website at www.vatek.com.tw for details.
