End-to-End Infrastructure Utilizes Gigabit Ethernet, Scrambling

and Edge Modulation for Reliable, Live Content to Cable Systems

Owned and Operated by BSI and Others

BigBand Networks, Inc., a leading provider of broadband multimedia platform solutions for broadcast television and on-demand services, today announced that Broadband Solutions Inc. (BSI) of Korea is deploying multiple services on the BigBand BMR(R) (Broadband Multimedia-Service Router) for nationwide management and distribution of live digital programming. This marks the introduction of digital cable in Korea, with content sourced in multiple headend facilities distributed by fiber optics to multiple cable systems throughout the country, including some owned by BSI and some by other operators accessing BSI's transport network.

"BSI has selected BigBand Networks for this project that requires excellent products with a broad range of functionality, as well as extensive engineering services to support an ambitious launch," said Chong-Ouk Kim, chief executive officer, BSI. "The BigBand BMR combines high speed switching and routing, intensive media processing and platform intelligence towards addressing all of BSI's needs in the project. BigBand Networks' professional services organization helps BSI utilize these technologies to reliably provide large volumes of high quality programming from various sources to national distribution."

BSI is more than doubling the number of programs available by Korean cable, with initial carriage of 130 video feeds and 60 audio feeds. These are either received in digital form or encoded out of analog form on BigBand Networks' platforms in multiple, networked headends. BMRs aggregate content at digital media centers (DMCs), where channel line-ups are controlled, local advertising is inserted, and RateShaping(R) is performed to maximize video quality while adhering to bandwidth constraints.

The groomed programming is distributed from DMCs by Gigabit Ethernet over optical fiber to multiple sites around Korea managed locally by BSI or by other service operators. At these sites, the transported content is de-jittered for further assurance of robust video quality, transcoded from Gigabit Ethernet to digital cable formats, and QAM modulation is performed on edge-based BMRs for access by any digital set-top box or television set. Proper access to content is assured by the DVB Simulcrypt scheme, and service is reliably provided to cable subscribers by the BMR's automated redundancy, that switches to an alternative program source when any outages or problems are encountered.

"BSI is ambitiously establishing the leading digital television deployment in Korea and one of the largest in Asia, in terms of both programs carried and geographic reach," said Amir Bassan-Eskenazi, chief executive officer and president, BigBand Networks. "BigBand Networks is pleased to play a role in this demonstration of digital cable's power to compete successfully versus multi-channel video and audio alternatives. Enhanced by BigBand Networks' broad platform capabilities, BSI and its partners reliably provide subscribers with an array of offerings expanding from high quality multimedia programming to more advanced services such as VOD."

The BSI deployment utilizes several services on BigBand Networks' platforms, including:

-- BigBand Real-Time Encoding - Encoding of analog sourced

programming in order to leverage digital service benefits;

-- BigBand Grooming - Control over channel line-up among video

and audio programs, including RateShaping for bandwidth

efficiency with video quality;

-- BigBand Ad Splicing Gateway - Inserts local advertising and

programming into national and international feeds by sourcing

content from servers and splicing seamlessly on cue;

-- BigBand Transport Gateway - Distributes high quality

programming between facilities based on standard protocols

such as Gigabit Ethernet with robust video quality and

automated fail-over to redundant sources in problem scenarios;

-- BigBand Access Gateway - Secure access by authorized

subscribers to premium and newly introduced services through

open methods such as DVB Simulcrypt scrambling; and

-- BigBand Broadcast Edge - QAM modulation and RF upconversion of

content to provide service to any digital device.
