The only task of the VPUs is video processing, which simplifies and speeds up the workflow by freeing up the CPU for other video tasks, resulting in 10x throughput at 1/10th the cost.
In the case of transcoding interlaced content, GPU hardware support is required for decoding the content. In this case, a single 1RU server can provide ABR transcoding of 90 FHD and 60 SD channels.
For local broadcasts, regional content ABR encoding and/or transcoding, mini server with lower capacity VPU hardware support. Additional SDI processing elements for high-performance ABR encoding.
