Grooming, Transrating and Multiplexing
Using proprietary Video Intelligence Architecture™ (VIA), the BNP provides the ability to transrate
program streams with the highest quality is unsurpassed in the industry. The BNP seamlessly grooms
multi-program transport streams (MPTS / MUX) and single-program transport streams (SPTS) on both
input and output ports. It also offers multiple Quality of Service (QoS) priority levels on any MPEG-2
program stream enabling selection of the desired level of transrating.
DPI-Based Ad Splicing
The BNP can concurrently groom and seamlessly splice both SD and HD program streams encoded in
either MPEG-2 or H.264 formats. This grooming and splicing capability eliminates the need to dedicate
multiple devices for different functions. The simplified installation, wiring and configuration reduces
system deployment time. The BNP is fully compliant with SCTE 30 and SCTE 35 standards and is
interoperable with the leading digital program insertion (DPI) ad servers. This flexible product can also
perform SCTE 30 to SCTE 35 conversion to support digital ad insertion at the hub. The BNP is an ideal
solution for both centrally located DPI systems at the headend facility, distributed DPI systems, and
zoned and targeted ad insertion.

Overview - BNP Applications
Messaging System Applications
BNP support for messaging system applications is described in the following topics:
•Digital EAS and Operator / Advanced Messaging.
•Graphic Overlay Insertion.
Digital EAS and Operator / Advanced Messaging
Leveraging its existing high-density video processing technology, the BNP’s digital Messaging System
capability allows operators to program both digital SCTE 18 Emergency Alert System (EAS) alerts and
operator-generated messages. The Advanced Messaging option allows importing graphics and text
files into the operator crawl message. EAS and Operator / Advanced Messaging alerts are delivered
universally throughout the network, overcoming existing challenges that cable operators face in
supporting analog and digital subscribers with an increasing range of decoding technologies.
The BNP’s Messaging System support can be applied selectively to any MPEG-2 program being
processed. EAS and operator-generated messages are digitally rendered and overlaid directly onto a
program, delivered directly to any digital subscriber set-top box or to analog decoders, and presented
as an overlay alert crawl to viewers. The BNP also supports operator-configurable audio override or
audio stream insertion to complement the text crawl message generated by industry-leading EAS
management vendors for a completely customizable deployment.
A BNP in an SCTE 18 digital EAS application is shown in Figure 5.

Graphic Overlay Insertion
In addition to EAS and operator messaging, the BNP Messaging System Logo Overlay option supports
insertion of graphic overlays into any MPEG-2 program being processed. Graphic overlays are based on
importing static graphic Portable Network Graphics (PNG) files. Importing text files is also supported,
meaning that customers can create a library of graphic and text files to routinely use (see workflow
example below). You can preview the imported PNG files before starting the overlay insertion.
The location of the insertion is configurable with positioning anywhere on the display screen defined
by (x,y) screen coordinates based on pixels relating to program resolution (e.g., SD and HD). Logo
overlay files can be created with PNG alpha channels to control transparency effects supported by the
BNP during the insertion of the overlay. Additionally, background transparency support is available for
non-ascii text overlays in order to support foreign markets.

BNP Deployment Architecture
The BNP’s modular and programmable platform is designed to provide operators with full processing
scalability to meet their specific processing requirements. The program density of the BNP is software-
configurable and upgradeable, allowing operators to start at lower densities and upgrade to the full
hardware capacity through software licenses as their stream densities and network needs grow.

Overview - BNP Deployment Architecture
This scalability reduces capital costs and allows operators to allocate budgets accordingly. By paying for
processing on an as needed basis, operators can wisely plan budgets based on today’s requirements
and avoid over-allocation to meet future needs. The programmable and upgradeable architecture of
the BNP, as well as its high processing power, eliminates hardware changes and will simplify and
expedite future deployments of new video processing applications.
The BNP supports both ASI and Gigabit Ethernet interfaces, allowing operators who deploy Gigabit
Ethernet networks to profit from the increased cost-efficiency offered with this transport, while still
providing support for operators with legacy ASI networks. This flexibility enables operators with ASI
networks to continue with their existing infrastructures while providing an upgrade path for a future
transition to an IP-based network.
The BNP has eight Gigabit Ethernet interfaces and is scalable to support up to 18 ASI interfaces using
up to three ASI modules. The Gigabit Ethernet interfaces are part of the BNP’s base configuration and
no additional hardware or licensing is required to utilize these ports. Providing added flexibility, each
ASI interface is software configurable as input or output by using an easy-to-use graphical user
interface.

Figure 9 shows how the BNP fits within the network for a centralized system architecture using ASI
interfaces. GigE interfaces could also be used for both input and output in a co-located headend
application.

Either ASI or GigE interfaces are used for MPEG input or output. Because of the distance, GigE
interfaces are typically used for transport between the headend and the hub/node.

Overview - Redundancy
Redundancy
Since a single BNP may deliver advanced video services to tens or even thousands of subscribers in a
video network, it is critical that the BNP provide a high availability of services. To achieve such reliability,
the BNP supports a multi-level redundancy feature to ensure service availability and reduce system
downtime. With proper configuration, the BNP can provide full chassis-level redundancy. On the
hardware level, a BNP provides fan, power, and chassis redundancy; on the software level, the BNP
Gigabit Ethernet port redundancy and a configurable program service redundancy feature.
Four user-configurable redundancy options are supported by the BNP:
•Source Specific Multicast (SSM) Redundancy
•Program Redundancy
•Port Redundancy
•1:1 Chassis Redundancy
The first three redundancies—SSM, Program, and Port—operate within a single BNP chassis. The
fourth—1:1 Chassis Redundancy—makes use of two BNP chassis. The redundancy for hot-swappable
fan trays and power supply modules happens automatically.
Source Specific Muliticast (SSM) Redundancy
The BNP supports the configuration of up to four source IP addresses per multicast input TS. The BNP
will join one of the four source specific multicasts, when configured. When the input PAT from the
current source times out, then BNP will switch to another source configured for that input TS. All the
streams coming from various sources must be identical (PIDs, program numbers, number of programs
etc.). Therefore, it does not matter which source specific multicast the BNP joins and receives program
information from at any given instance. Also, there is no priority associated with configured sources.
BNP achieves source redundancy using IGMPv3 SSM joins and leave messages. When SSM redundancy
is configured for an input TS, the BNP joins the first configured source specific multicast and waits a
maximum of two seconds for the reception of the PAT. If the PAT is not received in two seconds, then
BNP joins the next configured SSM and repeats the process until it receives a PAT. Video could be
interrupted for up to three seconds (in worst case).
SSM redundancy cannot be coupled with program redundancy on the same input TS.
Because SSM Redundancy requires IGMPv3, the router/switch connected to the GigE port of the input
transport stream must have IGMPv3 enabled.
For information on configuring SSM redundancy, refer to “Creating Input Transport Streams” on
page 109.
Program Redundancy
The BNP supports program redundancy, which is sometimes referred to as service-level redundancy.
For this type of redundancy, when the primary program is gone, the BNP automatically switches to a
redundant or backup program. If any elementary streams are missing from one of the ports, the BNP
switches to the secondary port.
In a program redundancy configuration, a switch to backup occurs when:
•Missing MPTS/SPTS streams are identified by checking the PAT.
