Video Networks Limited (VNL), a broadband service provider serving 2.4 million homes in London and Stevenage, has completed the migration of its broadcast television lineup to MPEG-4 AVC (H.264) compression.

VNL, which offers a range of IP-based video services, including video-on-demand under the HomeChoice brand, is powering its advanced compression platform with Harmonic Inc.'s DiviCom MV 100 multi-codec encoding platform.

VNL began deploying the DiviCom gear in early 2004 in the MPEG-2 format. During the migration period, new software was added to the Harmonic encoding gear to support the more bandwidth efficient MPEG-4 codec. VNL is also using Harmonic's NMX Digital Service Manager to monitor and control its digital television infrastructure.

"The ongoing improvements in advanced encoding will enable us to free up bandwidth, which can then be used in our continuous quest to provide ever more advanced products and services for our customers," said VNL Chairman & CEO Roger Lynch, in a release.

"We see the benefit of advanced encoding in MPEG-4, combined with European service providers' migration to ADSL2+, enabling the sector to provide HDTV in the very near future."

About 4,000 DiviCom MV 100 systems are in service today, according to Patrick Harshman, president of Harmonic's convergent systems division. The device can also be outfitted to handle the SMPTE VC-1 codec.
