SDI Frame Synchronization and Delay

Model: DSFS6802+D

  • Dual-channel independent SDI frame sync and delay processing, including audio and VANC data such as WSS/VI/AFD; capable of operating at different formats in the same frame rate domain
  • Auto-sensing SD/HD/3G-SDI signal standard per channel
  • User-selectable input and output standards/formats
  • One SDI video input, two SDI video outputs per channel
  • SDI input error monitoring

The DSFS6802+ is a configurable, cost-effective and easy-to-use dual-channel frame synchronizer and delay module with embedded audio processing for 3G/HD/SD-SDI signals.

DSFS6802+D modules feature dual, independent SDI video/audio channels on a card, and can be configured to support a wide variety of multichannel applications. Each processing channel has its own video/audio processing blocks, such as audio de-embedder/embedder, SRC, audio delay/synchronizer and frame synchronizer/delay. The modules support one input and two outputs per channel and can support different video standards per channel.

The onboard genlock input can come from either frame reference or card reference. The two processing channels share the same genlock input.

The DSFS6802+RLYD back module was added as a dedicated back module (requires special P/N for ordering) that supports input-to-output relay bypass for frame sync applications.

  • Dual-channel independent SDI frame sync and delay processing, including audio and VANC data such as WSS/VI/AFD; capable of operating at different formats in the same frame rate domain
  • Auto-sensing SD/HD/3G-SDI signal standard per channel
  • User-selectable input and output standards/formats
  • One SDI video input, two SDI video outputs per channel
  • SDI input error monitoring
  • Video frame and audio sync with genlock support
  • Full 3Gb/s support capabilities (up to Level B-DL)
  • Fast-switch for clean/quiet output on hot switch at the input with no output frame freeze
  • Dolby® E header adjustment/realignment
  • 10-bit video processing
  • Passing of all HANC and VANC samples
  • VBI pass/delete
  • AFD/WSS/VI detection and insertion
  • Video thumbnail, selectable between output one and two
  • Eight GPI inputs (TTL) and 4 GPI outputs with multiple configuration options to control both channels
  • Rules engine: custom GPI in/out, and parameter control scripts
  • DSFS6802+ supports two back module types: Standard (+D) and with Relay Bypass (+RLYD)
  • VIDEO
    • SDI video standards:
      • 525 and 625 (SMPTE 259M)
      • 720p (SMPTE 274M/296M)
      • 1080i/p (SMPTE 292M)
      • 3Gb/s (1080p) (SMPTE 424M/425M) Level A, Level B-DL
    • Video delay (sync or delay modes):
      • 3G-SDI standard more than seven frames in Level B-DL, more than 17 frames in Level A
      • HD-SDI standard more than 16 frames
      • SD-SDI standard more than 20 frames
    • A-B sync mode support:
      • In A-B sync mode, FS/delay related parameters and Video Proc Amp parameters of channel B will follow the settings for channel A
      • The two channels frame sync drop/repeat operations are synchronized
      • The two inputs must be in same clock domain (locked together) before fed to DSFS
      • The delay between two video inputs must be within three lines
