The document discusses packet-to-packet media processing and transcoding applications using the SurfUP media processing platform. It highlights the needs for these applications, optimal system architectures, and how SurfUP supports them through DSP chips, boards, and software that provide high density voice, video, and fax transcoding and processing with low latency and an open platform.
