Multichannel Mosaic Builder AL Mosaic
The AL Mosaic creates mosaics from multiple input streams and outputs it in single MPEG2 or H.264 transport stream. Up to 20 MPEG2 or H.264 streams can be inputted. The output is a single MPEG2 or H.264 video stream with 20 audio streams respectively.
The background and scene layout of the mosaic can be easily customized by the user. Audio bars for each channel can be displayed for audio monitoring purposes.
The AL Mosaic is ideal for video-over-IP broadcasting and monitoring. With its high level integration, the AL Mosaic enables providers to significantly reduce their transmission costs.
- Create a mosaic of:
- 20 MPEG2 SD channels
- 20 H.264 channels
- 9 MPEG2 HD channels
- 6 H.264 HD Channels
- Easily customized background and layout
- Output stream as MPEG2 (SD or HD) or H.264 (SD)
- The AL Mosaic is easily integrated with set-top box applications such as interactive program guides.
- With its ability to display up to 20 channels simultaneously, the AL Mosaic is ideal for monitoring applications.
