The Fidelity transmitters are modular in construction; the 2 kW Class D power modules are hot-swappable. The line offers an integrated DRM exciter, making DRM operation available with the push of a button.
metadata and decoded imagery is fed to the VideoBridge Controller. Disruption of descrambling services is one of the main causes for service production disruptions in the head-end and for the first time cost-effective monitoring of scrambling is available.
Further applications are in middleware scenarios for generating thumbnail mosaics or for extracting stream metadata such as picture resolution, video bandwidth or wide screen signalling information.
Digital AM-DRM transmitter
The transmitters can be controlled locally or remotely via IP Settings and logs can be stored on an SD card.
RIZ also makes shortwave transmitters with solid-state modulators and output power up to 500 kW; solid-state long-wave transmitters with up 2,000 kW in output power; and FM transmitters with output power up to 30 kW. (

Nimbra 310 Unveiled The Nimbra 310 has been introduced by Net Insight, a compact one-box access MSR for true multi-service transport of media and data services. The Nimbra 310 is a multi-service router (MSR) for remote access application designed to accommodate a variety of settings, including remote production branch offices, “leaf” nodes in a DTT transmitter network and event contribution settings where only one uplink is available. The system offers an alternative to IP gateways, providing a full set of signature MSR capabilities. It contains one trunk port, one slot for plug- in units and one sync/time transfer interface. The Nimbra 310’s built-in Ethernet access functionality provides support for Ethernet switching between eight physical ports and up to 119 logical ports.

The VB280 is equipped with Ethernet data input either as 10/100/1000T electrical or SFP based optical. A separate Ethernet management port is provided for data transfer. Each VB280 runs an HTTP server with the client as a web browser, so no need to install custom software on computers needing access to the measurement data.

The latest version of the open operating system for IP set-tops – Motorola KreaTV, version 4.4 has been released.
Some of the new features available in KreaTV 4.4 include web browsing, as well as HTTP live streaming, including support for content encryption, enabling service providers to expand their footprint with over-the-top (OTT) services. This allows the same hardware to be used in an IPTV as well as OTT environment.
USB time-shift enables operators to add new time-shift features such as pause live TV to the set-top, using a USB memory stick as storage. Retransmission and fast channel change, based on IETF (Internet Engineering Task Force) standards: these capabilities improve the user experience, as channel changes are quicker and there is less video degradation in the event of packet loss, making services over longer xDSL connections possible.

IP Transmission System for Live HD Video Production
IP transmission unit Content extractor device
The VB280 CONTENT EXTRACTOR offers thumbnail and metadata extraction for up to 100 TV multicast streams concurrently via GigE interfacing. The VB280 CONTENT EXTRACTOR is ideal for visual at-a-glance monitoring in the NOC, VOC, head-end or remotely via any standard web browser. The VB280 is typically inserted before scrambling insertion in the head-end and the extracted
To bring IP technology into the world of video production, Sony has developed the NXL-IP55, a video network unit that can transfer multiple HD image signals, audio signals and control signals over a single network cable. These units may be used, for example, when filming in a theatre or stadium, whereby images are transmitted simultaneously from multiple cameras with as minimal delay time as possible.
