Design Considerations

Video Infrastructure transcoding systems are widely used in broadcast, content delivery, and cloud media service networks. In these systems video content can be provided from multiple sources: network streaming, local and remote storage facilities, or live feeds. Once received, the content is often transcoded in real-time, or faster-than-real-time, and converted to a variety of content formats tailored for network bandwidths and client display formats.

Video transcoding may be performed with or without fully decoding the original content. Transcoding without full decoding implements special algorithms to reuse partial coding parameters for recoding. In this case, application-specific algorithms are deployed to prevent quality drift incurred by incomplete encoding loops. Whereas using the full decode technique the original content is decoded into pixels before encoding to the desired output. This transcoding approach has become very popular, allowing pixel-level mid-processing functions such as: content enhancement, video analytics and alpha-blending.

This concept VI system combines the highly-integrated Davinci Digital Media System-On-Chip (SOC) with an optional multi-core DSP module that handles 4:2:2 professional video and enhanced video analytics.

The base transcoder system includes:

  • Integrated Host Processor – An ARM Cortex A8 GPU with full Linux platform support package
  • Video processor – Dedicated video coprocessor enables up to 3 simultaneously AVC transcoding, from High-profile to High-profile
  • Audio Processor/DSP – C67x DSP core
  • Video Preprocessing – Integrated noise filter, video enhancement, scaling and alpha-blending engines
  • PCIe backplane – 2 lane PCIexpress backplane
  • Transport Interface - Integrated Transport interface
  • User Interface - Allows the user to access the stored files and communicate with other applications in the network
  • Network Interface – dual gigabit Ethernet GMII
  • Power Management – AC-to-DC conversion and regulation that creates an efficient power source for: the core and I/O supplies of the main processor, DDR and system memory.

Optional Multi-core DSP Processor Blade:

  • Backplane - Connect to DM816x via 2xPCIe backplane.
  • Massive DSP Processing – up to 10GHz of new C66x DSP core with floating support
  • I/O Capabilities – 4x SRIO or 2xPCIe for interconnect with rest of system
  • Network – dual Gigabit GMII with built-in switch
  • HyperLink – high-speed interconnect path between devices

Optional Local Live Feed module:

  • HDMI digital capture – up to dual-channel 1080p60 capturing with audio
  • HD-SDI – up to dual-channel 1080p60 capturing with embedded audio
  • Analog – up to dual-channel analog HD input
  • Audio – analog or digital input

Optional Local Storage Module:

  • Hard Disk – Integrated Serial ATA with integrated PHY
  • USB – Integrated dual USB 2.0 with integrated PHYs
