APT adds video over IP option for Oslo
APT used NAB2009 to launch its new video module for its WorldNet Oslo Broadcast Platform that adds the ability to transport high-quality JPEG2000 content for video over IP applications.
“We have chosen to support the Motion JPEG2000 video format as it offers three key benefits: professional quality content, low delay coding for real-time delivery and an ability to work well with the packetized approach of IP transport,” said Hartmut Foerster, product manager for APT video products.
Motion JPEG2000 technology works together with the low-latency, Enhanced apt-X audio algorithm to provide broadcast-grade audio and video with minimum delay while still ensuring bandwidth efficiency.
New key product features include:
- Low-latency (near real-time) video/audio data over IP using JPEG2000
- Low-latency audio data over IP using Enhanced apt-X
- Multichannel audio tracks (eight channels) alongside the video stream or embedded into JPEG2000
- Single-card solution for eight-channel audio and video (either encoder or decoder)
- Professional interfaces for video (SDI) and audio (AES-3)
- Scalability from low-quality distribution to broadcast contribution
- Modularly designed frame architecture
- Full integration in the WorldNet Oslo control and management software
JPEG2000, a near real-time video format, combines with the Enhanced apt-X audio algorithm to deliver high-performance, broadcast-grade audio and video with minimum delay while still ensuring bandwidth efficiency. The video encoder/decoder modules for the WorldNet Oslo fit into the current architecture and can sit beside other payload modules such as audio, voice or auxiliary data cards for delivery over IP networks.
The WorldNet Oslo is based on a 19in, 3RU standard rack-mount chassis that is card-based expandable. Redundant power supplies, hot-swappable cards and automatic backup functionality ensure 24/7/365 reliability for mission-critical applications such as studio to transmitter links. Various network interface modules dispense with the need for external multiplexers or media converters. Audio can be transported via synchronous or packet-switched networks with support for T1 (1.5Mb/s), E1 (2Mb/s) and Ethernet (IP) interfaces.
All unit settings can be managed remotely using APT's Codec Management System (CMS). A GUI provides extensive configuration, control and fault monitoring capability of multiple WorldNet Oslos and other APT IP audio codecs. In-band management enables control and monitoring of a network of units over E1/T1 without additional dedicated communications links.
