B2Mosaic is a digital mosaic generation system, allowing to compose a navigation screen with multiple thumbnails created from video streams (SD or HD) or still pictures. As the system directly receives the input streams from its IP or ASI interfaces, the system is fully autonomous, and does not need any supplemental encoding or decoding devices.Each device is a 1 RU PC-based plateform allowing the composition of a picture including up to 20 thumbnails. Each input service is scaled and repositioned in order to compose the final picture. This picture is then encoded and broadcasted in a MPEG2/TS stream, alongside audio channels, MPEG-2 tables, and metadata. Finally, the mosaic allows to broadcast application based upon client middleware, in order to integrate easily in every set-top-box environment. If 20 thumbnails is not enough, it is also possible to link several devices for increased computing power, or to handle multiple “mosaic pages”, each page being displayed in order for an amount of time configured by the user.

The mosaic composition is done using a WYSIWYG application, which connects to the B2Mosaic platform to seamlessly update its configuration. For each thumbnail, it is possible to define a size, the service it will contain, as well as cosmetic options (e.g. rounded corners, …). It is also possible to copy/paste thumbnails in order to speed up the layout design.
