German manufacturer WISI has set out to meet the challenges of merging Web and TV. The company will display innovations and fitting intelligent systems at ANGA COM 2017, booth R11, hall 8.
Wisi has expanded igts headend platform Chameleon with two high density encoders. The new encoders offer an outstanding price performance ratio and are ideal for applications in the hospitality industry. The first new encoder has up to four HDMI inputs. The second encoder offers up to four HD-/SD-SDI or analog Audio/Video inputs. Both encoders are equipped with an integrated advanced multiplexer, support MPEG-4 and MPEG-2, and are easy to combine with a Chameleon processor for further applications, such as Edge QAM, PAL and COFDM. They are also easy to handle through a user-friendly interface that is integrated in the Chameleon system management. Depending on the application scenario, the two encoders can be combined with the four different Chameleon base units GN 01, GN 20 B/R, GN 40 and GN 50.
Wisi has optimised the efficiency and application options of our successful headend platform Tangram for IPTV and analog/digital TV solutions. The number of QAM channels in Annex B has been doubled for each module, from six to twelve – without additional costs. Also, the number of IP inputs has been increased to up to 128 streams per module and the data processing throughput has been raised from 800 Mbps to up to 1.7 Gbps.
A new Tangram feature is the Verimatrix bulk decryption. Video operators can deploy the flexible and modular Tangram chassis and cards to receive and decrypt up to 128 unique 4K, HD or SD Verimatrix scrambled video services, and then output them as any combination of IP, ASI, digital QAM or modulated analog CATV. We have raised the service quality of this platform by an active monitoring function of redundant inputs. The optimised user interface reduces the configuration efforts of the TANGRAM system for the platform operator while in operation. Moreover, TANGRAM now supports the new satellite TV broadcasting DVB-S2X and offers additional features, such as Traffic-Shaping and SNMP (Simple Network Management Protocol).
With the versatile micro headends OM 10 (DVB-S/S2 -> DVB-C/T) and OM 11 (DVB-C/T/T2 -> DVB-C/T), WISI launches a new optimised headend solution in an ultra-compact design for operators of TV distribution systems in hotels, hospitals and residences. With this new solution WISI meet the high expectations concerning functionality, flexibility and user-friendliness. Because of their multiplex functionalities before and after the CI-modules, the micro headends are perfect for the central and very efficient decryption of pay TV channels. Unique features in this headend class are the options to feed in and stream own video content via the USB interface, such as an info channel in a hotel or a hospital or the use of static service IDs at the output. Thanks to this new feature, no new TV scan is necessary if there are service changes at the input of the TV device.
At ANGA COM, WISI will for the first time show its new in-house developed multiswitch series Proswitch. These sophisticated multiswitches are the perfect solution for professional digital satellite reception and signal distribution systems. The series offers different cascadable multiswitches with 5, 9 and 17 inputs. In addition, with the optional power supply DG 55 that powers the LNB, the multiswitch functions as a stand-alone device.
Commercially available DVB-S/S2 set-top-boxes or TVs with an integrated receiver can be used at the 8 (DY 0508, 0908, 1708) or 16 subscriber outputs (DY 0516, 0916, 1716,) and receive signals from up to four satellites. Inserted terrestrial signals, such as DVB-T/T2, DAB or FM are available at each subscriber output as well. Through the passive terrestrial path, multimedia services such as “LAN over Coax” or signals from a headend system can be fed in.
Each multiswitch has an integrated SAT amplifier for low insertion loss. The stand-by functionality minimises power consumption by activating the multiswitch only in case there is a switched-on STB connected. Another device of the new Proswitch series is the SAT amplifier DY 40 for four SAT polarisations. It is perfect for building up large multiswitch systems and can be extended to several satellites by putting together more DY 40s. The gain is 30 dB in the frequency range 950…2150 MHz. Via a push button, the gain can be reduced in 1 dB steps by up to 19 dB. Additionally, a slope adjustment is possible to compensate frequency depending cable loss up to 12 dB.
WISI also introduces the next generation of CATV splitters and taps. These new passive components have an extended frequency range of up to 1.3 GHz, and a high intermodulation suppression. Therefore, they are well suited for future DOCSIS 3.1 applications in in-house distribution systems. Together with the new available 1.2 GHz amplifiers of the VX series and the new in-house junction XU 70, WISI now offers a complete portfolio for future frequency expansions in cable networks.
