Ligos Video Mosaic – Technical Data

Illustration of how three video Mosaic channels can be easily implemented within the headend and delivered to the subscriber using Ligos Mosaic , including those for redundancy and rollover management and monitoring

Mosaic is an all-digital MPEG-2 software solution that utilizes Gigabit Ethernet interfaces for input, output, and management, and easily integrates into today’s multichannel architectures. The software consolidates all of the required functions – input, decoding, re-scaling, compositing, XML navigation metadata generation, channel mapping, encoding, multiplexing and output – into a single, compact platform that can be managed online in real-time, either locally or remotely. In addition, a network-based monitoring solution, Mosaic Fail-Safe Supervisor, is available.

The easy to use Mosaic Control Client user interface - click to enlargeThe Mosaic client user interface provides the operator a straightforward and precise way to produce engaging layouts that include video, still graphics, text and navigation elements as layered elements positioned over branded still or motion backgrounds of their own creation. Tile contents can be dynamically changed and keyed on/off as-needed, and layouts and assets can be saved and recalled for future use. The integrated Channel Map utility and XML-based architecture makes mosaic configuration portable, easy to use and ideal for integration into external control systems.
