2 3.1a B-Nova Chassis 3.1a B-Nova The B-Nova chassis is a base for a modular IPTV platform and cable TV headends. B-Nova enables the operator to setup a very compact headend configuration using various processing and interfacing modules. B-Nova scales from one chassis headend in a box to a multiple chassis bigger headend system. The Architecture of the B-Nova platform enables a very high performance with a very low power consumption. B-Nova architecture The B-Nova chassis has 6 module slots for interface and processing modules. The B-Nova architecture is future proof to support new module development later on by having all stream processing features in sub modules. Therefore, new functionality can be introduced later into the platform without touching the chassis. The stream processing in B-Nova is distributed to sub modules, which utilize virtually unlimited processing capacity in practical configurations, without problems typically caused with a central shared processor. All sub modules can process independently incoming and outgoing streams. The internal router of the chassis makes the interconnection between sub modules and the two payload gigabit Ethernet input and output ports. This means much less cabling at the headend and thereby simplifies headend configuration. The router also has a separate internal management network for sub modules and a chassis which guaranties reliable operation also in high-load situations. All internal connections are gigabit Ethernet which enables high-performance operation. Common management interfaces and power feeds for sub modules are also created in the chassis. High-density design The new component technology and selected architecture for B-Nova creates a very high-density design, which saves a lot of rack space compared to traditional headend setups. B-Nova can have up to 12 receivers with descrambling capability in one chassis. If 6 quad receiver modules without descrambling are installed into the chassis, it increases the receiver count up to 24 in the chassis. Using quad -modules means that one chassis can have up to 24 inputs or outputs. Installing six quad QAM modules means up to 24 QAM per chassis or up to 24 RF-out in COFDM. The B-Nova chassis can also have a mix of modules to adapt to the various application needs of the operator. Scalability In accordance with the B-Nova system architecture, the video processing is performed on sub modules, which enables lowcost applications even with a partially equipped chassis, while having the performance scalability to a fully equipped chassis. The B-Nova has virtually unlimited line speed capacity for stream processing in practical applications, which means that the B-Nova chassis doesn t limit any practical configurations. The chassis has two gigabit Ethernet ports for payload traffic. These ports can be used as inputs and output depending on the sub modules installed. Two Gb/s streaming ports will act as payload sharing or redundancy There is no limit for the maximum amount of services in the chassis, which makes it possible to process a high amount of services in the same chassis. Practical setup can be from several tens of services up to services in the same chassis. Using a multiple chassis in the headend scales setup can provide a virtually unlimited amount of services. Managing cooling B-Nova has managed horizontal ventilation, where internal temperature is actively monitored and fan speed is adjusted according to the required cooling capacity. Typically, fans rotate well below maximum speed, which increase their lifetime and generate less noise. The chassis cooling capacity is designed to support up to 100 W heat dissipation, but typical setup takes less power. The fans can be replaced during live operation without service interruption. The fans are located behind the front panel. Inputs and Outputs in Power module The Power and input/output module have two gigabit Ethernet SFP module slots for streaming payload traffic and IP inputs depending on the sub modules installed. The SFP module makes easy adaptation to electrical and fiber media to create interconnectivity from B-Nova to other devices. The module has two management interfaces (100Base-T). The first one is typically used for general management purposes, and the second interface is dedicated connection to Conditional Access Servers. The USB port can be used for first time setup using terminal software through serial connection profile. Redundancy To minimize service outage because of hardware failure, B-Nova supports 1+1 redundancy in the chassis level. To keep the B-Nova platform as cost effective as possible, all internal redundancy features are minimized. The pair of B-Nova can be configured to act in main and backup schemes, where secondary B-Nova monitors the main status. The secondary B-Nova configuration is automatically synchronized with the main B-Nova. The secondary B-Nova stays in stand-by mode until failure occurs in the main B- Nova. When the selected failure event trigs or the main unit is not responding, the main B-Nova shuts down all payload outputs based on dedicated hardware circuitry to ensure switch off of all streaming. The secondary B-Nova then takes over the stream processing operations. A virtual common IP address can be assigned to the pair of B-Novas to introduce them as one device to higher-level management software. Still, both devices can be accessed through their own IP address.

3 3.1a B-Nova B-Nova Chassis Embedded DVB Content Protection B-Nova has the capability to protect services with DVB scrambling. The chassis provides DVB Simulcrypt interface to Conditional Access systems, which allows integration with a large variety of CA vendors. The content protection has been designed to scale to a large number of scrambled streams with minimal system configuration. The actual scrambling is an integrated feature on the B-Nova sub modules, which provides scalable performance and maximum flexibility of the system configuration, supporting both centralized and decentralized scrambling solutions. Any service can be scrambled simultaneously with two CA systems. Other advanced features include short-key change intervals, automatic PSI/SI table generation, detailed monitoring of the interaction with CA system, support of redundant ECM generators and scheduled changes of the content protection properties. Management The B-Nova chassis has centralized management features for configuration and status monitoring of the sub modules and chassis. Management features are optimized for typical CATV or IPTV headend operations. There are many helpful features to make headend daily operation easy and effective. An Intuitive WEBUI is designed for easy management and monitoring for troubleshooting. It allows the user to establish setup quickly just by entering a few parameters, and then let B-Nova do the detailed configuration based on internal intelligence. There is still the possibility to also adjust the detailed configuration for professional users. Automatic service identification and PID remapping based on internal rules create unique values for all streams. Therefore, it is very easy to do the system-level configuration. CLI (Command Line Interface) is helpful to do configuration updates in patches and also makes it possible to manage B-Nova through low-speed communication links. Monitoring parameters and warning/alarm messages are available using SNMP protocol and traps. This allows integration to the element management system or higher-level management systems. The front panel has an indicator to get a quick overview status of B-Nova. When all indicators show green, then everything is running as expected. Also, all sub modules have status indicators for module operation and interface indicators for signal status. Indicator lamps are helpful to locate interface or a module that requires action.

5 3.1-2 B-Nova 3.1c Backup-PSU/External Housing B-Nova uses external backup power for securing main power supply located in chassis. Backup Power is connected to DC IN connecter in main power supply LPS-B. Its internal switching circuit automatically takes power from external power supply, if main power supply fails. Physically backup power supply module can be installed either separate backup power supply chassis LCH-C or B-Nova main chassis LCH-A, if it has two free slots in top of each others. 3.2 B-Nova Receivers The B-Nova receivers provide a very compact receiving platform for Cable TV and IPTV operators. The receivers enable flexible selection of free-to-air and scrambled services from DVB-S, DVB-S2, DVB-T or DVB- sources, which can be adjusted to the operator s service line-up with the builtin advanced transport stream processing capabilities.
