Riedel Communications presents MediorNet

Riedel Communications presented MediorNet, which combines signal transport, routing and signal processing, and conversion into one integrated real-time network. MediorNet is not designed just for simple point-to-point links but offers a network solution that includes signal routing, allowing users to send any incoming signal to any output or even to multiple outputs by just a mouse-click or by a router control system.

Each MediorNet mainframe provides a router for 32 x 32 720p/1080i signals, 184 x 184 SD-SDI signals, 27,000 x 27,000 AES signals or any combination of these. MediorNet has an open network topology, supporting ring, star, daisy-chain or any combination. This allows users to design the system exactly to their requirements. The sysetm offers Link Cards with and without integrated CWDM multiplexing to network MediorNet mainframes with a bandwidth of up to 153Gbit/s on a single fiber link. A MediorNet fiber link always consists of duplex fiber to allow bi-directional signal transport. Its standard fiber transceivers have an optical budget of 18dB minimum, allowing for distances of up to 25mi. Transceivers for longer distances are optionally available.

MediorNet’s routing algorithm is always looking for the shortest path to transport a signal and optimizes the bandwidth of all fiber links available. This includes hops over other MediorNet nodes, when no direct fiber connection from the source to the destination is available. It also includes software-based broadcast-quality processing and conversion on board. The open structure of the software allows the easy integration of future processing and conversion tools from Riedel or third-party manufacturers supporting the MediorNet standard, without any changes to the hardware. Ultimately, this will eliminate the need for external devices.

Current features include a broadcast-quality HD/SD up/down/crossconverter with interlacing/de-interlacing, up-/down-scaling, frame synchronization and aspect ratio conversion. In addition, MediorNet provides a multiviewer and a test pattern generator.

The Best Deconstruction of a 4K Shoot You'll Ever Read
With higher resolutions and larger HD screens, wide shots using very wide lenses can be a problem because they allow viewers to see that infinity doesn’t quite resolve into perfect sharpness.
