Tieline Launches QOS Performance Engine for Remotes via IP
Indianapolis - Mar 20, 2008 - At the 2008 NAB Show, Tieline Technology will demonstrate its new QOS Performance Engine Technology over IP for its G3 range of audio codecs, which provides greater connection stability, with less delay, for live remote broadcasts over IP networks.
The Internet and 3G wireless networks are lossy, packet-switched networks in which a percentage of data packets sent never arrive. Tieline notes that between one and three percent of packets are lost at different times over open Internet IP connections. This figure likely increases to between three and ten percent of packets via 3G networks.
In a remote broadcast situation, broadcasters are unable to buy QOS (quality of service) for wireless 3G networks, and it is often impractical to buy QOS for a single remote broadcast for the Internet. The QOS Performance Engine Technology is Tieline's answer to this. The technology manages the IP connection and adjusts settings in the codec to allow for varying packet arrival times and provide forward error correction (FEC) analysis.

Clear-Com Systems Eclipse Digital Matrix v5.0
Booth C 5908
Version 5.0 of the Eclipse Digital Matrix intercom system acts as a central switching unit for communications across a broadcast operation. The system links Clear-Com V-Series panels and Cellcom wireless beltpacks and headsets for access to communication in the studio or in the field with more connectivity options. Working with an E-FIB card, fiber linking between Eclipse intercom matrixes of the Median and Omega classes enables large productions to tie their intercom systems together. Multiple Eclipse systems may then act as one non-blocking matrix using redundant high-capacity fiber, resulting in a large, high-quality, full-duplex communications system for mobile production and studio integration. An AES-6-RJ interface card allows the user to control remote V-Series Panels through AES3 stereo digital audio routers and consoles where the Eclipse intercom is required to talk over audio feeds.
Broadcast Electronics Audio Vault X
Studio automation platform
Audio Vault X is a new studio platform with more capacity and flexibility for adding and personalizing format channels on the Internet or over the air. Audio Vault X handles complex segues, such as inserting donut tracks in the middle of a song, station ID or weathercast. It can even create double donuts: drop in a voice or other segment in the middle of a song or jingle twice. Plus, talent can manipulate fades, audio levels and other characteristics of segues. Personalized studio mashups combine studio tools and applications from more than one source into a single workspace. The Audio Vault X multi-thread engine enables talent in separate studios to work collectively off the same log, in real-time. Audio Vault X is a suitable for live-assist or satellite operation. The new platform offers on-air studio operation as well as a full suite of scheduling and production modules for multi-track editing, music rotation and ad insertion.
Neutrik IP65 Rated Opticalcon
Rugged optical connectors
This connector has been upgraded for dust-tight and water-jet protection. The upgrade extends the outdoor capabilities of the Opticalcon, making it ideal for mobile trucks and other outdoor broadcast settings. This is especially useful when weatherproof extensions are required. To achieve a water-resistant IP65 connection, additional seals and gaskets have been employed on the chassis connector and cable ends. For earlier versions of Opticalcon cable connection systems, an upgrade kit is offered so it can be combined with the upgraded NO2-4FDW chassis connector or NAO2-4S75W coupler. The new cable ends are 100 percent backward compatible and work with all existing chassis installations.

Adam Professional Audio A5
This powered monitor uses the same technology as existing Adam monitors. Technically, the A5 is a smaller version of the A7, and can be used either in stereo or to fill out a 5.1 surround system. Powered by 2x25W on-board amplifiers, the A5 combines Adam's accelerated ribbon technology folded ribbon tweeter with a 5" woofer constructed of a carbon fiber and Rohacell sandwich. The front of the A5 sports dual ports for low frequency response down to 55Hz, metal grills for added durability, as well as power and gain controls. The rear panel includes balanced XLR jacks, unbalanced RCA jacks and Stereolink, which connects speakers with input and output jacks, allowing the user to control the overall volume of the system from any one speaker's gain control.
APT Worldcast Horizon HD
HD Radio audio codec
The Worldcast Horizon HD is a duplex stereo codec that enables broadcasters to deliver FM and HD content from studio to transmitter site. With both a T1 and Ethernet interface, broadcasters can utilize existing T1 links for the FM transport and send their HD content as a UDP stream embedded in the T1 link, eliminating the need for additional bandwidth and cost. At the remote/transmitter link, the HD content is presented back on an IP port. As a fully duplex device, Worldcast Horizon HD allows off-air monitoring or an independent channel to backhaul RPU feeds and satellite downlinked audio. An RS-232 port is available for PAD and contact closures for remote control.
Vinpower Digital Xerox-branded tower duplicators
Standalone disc duplication
Booth SL 7709
The Xerox-branded standalone tower duplicators offer the ability to transfer image files directly from a PC to the duplicator's internal hard drive, saving users the time and effort usually required to produce a master disc for each project. With a range of SKUs from 1:1 up to 1:15 writer drives, each operates independently of a PC. Several models in the line also provide users with a 256MB buffer memory for more stable and reliable high-speed duplication with a greatly reduced occurrence of buffer underrun errors.
Inovonics Model 525
AM reference receiver and modulation monitor
The 525 is a frequency-agile, wideband AM-broadcast receiver that utilizes a highly linear phase-locked detector to provide accurate off-air measurements of AM carrier modulation. An important feature of this new monitor is the ability to resolve the amplitude-modulation component of the station's carrier during IBOC Hybrid Digital broadcast operation. Positive and negative carrier modulation is shown simultaneously on a high-resolution LCD display. This can be switched to provide a read-out of received signal strength and asynchronous noise as well, two parameters that can influence the modulation reading. Measurement response is pancake-flat to 10kHz, although a menu-controlled low-pass filter in the audio-monitor output provides a cutoff that can be programmed between 10kHz and 2kHz in 1kHz steps. This allows the user to preview the sonic compromises imposed by pre-transmission audio filtering and to simulate the response of consumer radios.
