Hannu Pro to supply an advanced Grass Valley driven
DVB-T/IPTV head-end solution
|
 |
At the beginning of 2010 DVB-T broadcasts should cover all territory of Latvia. Working in close cooperation with Grass Valley, Hannu Pro will deploy an advanced head-end to form signals for DVB-T and IPTV broadcasting, thus Lattelecom - Latvian DVB-T provider - will be able to deliver the highest quality content and services. New head-end will receive signals from satellite as well as from local television stations and will encode them into MPEG4 streams using highly effective encoding tools and Statmux algorithms, which provide much better quality picture at just half bit-rate. Also powerful muxing solution required for optimal signal formation process will be supplied.
Solution developed by Hannu Pro includes more than 40 Grass Valley SD and HD IRD devices for satellite and SDI signal reception and decoding, supporting n+1 redundancy; Grass Valley Gecko Flex series modulars for signal processing and synchronization; an advanced fully redundant Grass Valley Trinix 256x256 SD/HD SDI router with Grass Valley Jupiter CM4000 controller; Grass Valley ViBE SD (EM1000) and HD (EM3000) encoders (n+2 and n+1 redundant) to encode 80 SD and four HD channels; Grass Valley NetProcessor 9040 multiplexers (1+1 redundant), which will form signals for 6 broadcast networks (multiplexes) and also will provide Statmux control for encoders, insertion of Conax conditional access information and PSI/SI (Program Specific Information / Service information), as well as perform transrating, splicing and other advanced functions; Grass Valley Acapella ASI switchers to transport the signals to Riga transmitters and LVRTC systems for further signal distribution over all Latvian DVB-T network; six Granite Sentinel systems for uninterrupted ASI, COFDM and IP signal monitoring to comply to TR 101290 DVB standard; Grass Valley Jade and Coral systems generating EPG information and providing an option for user set-top-box system updates, as well as MHP (multimedia home platform) information for interactive home entertainment. All system components will be controlled and managed by Grass Valley XMS/XMU network management system (NMS). Project also includes Actus Imago content monitoring system to provide alternative continuous content logging for 8 TV channels; Apantac Tahoma HD SDI and SDI multiviewer 64 channel system; five high quality JVC 42/50" professional monitors; Leader signal control and measurement equipment; as well as Bridgetech QPSK system for satellite signal control.
Newly developed DVB-T and IPTV head-end will support complete encoding and multiplexing of 80 SD channels (40 with VBR encoding and 40 with CBR encoding) and four HD TV channels to be broadcasted in Riga area, as well as into Latvian DVB-T and Lattelecom IPTV networks. Project market value reaches EUR 1.8 million.
