Show Creation

Delta has a full, frame accurate, multi-timeline based show creation GUI which allows the operator to place media, controls and complex events on any of the 32 built-in timelines, fading each into view as required.

The GUI is an intuitive drag & drop user interface, with direct access to multiple resources, multiple timelines and multiple servers from the single instance of the Delta GUI program.

The powerful GUI also provides direct access to detailed configuration of the server, warp & blending of all projection channels, display configuration & management, spline editing, mesh editing and even dome projector layout design.

For some applications, full timeline editing is not required, and in this case, there are Playlist resources where the operator can simply drop media into a playlist container which repeatedly plays them in order until stopped.

The playlist items can be set to repeat once, multiple times, or wait on external control triggers – for example a video/audio holding loop is played until the customer’s equipment commands it to move onto the main show.

Delta GUI also provides simple dialogue-based wizards to create a slide show, 3D Stereo show, warp & blend layout for flat screen or dome display systems.

Playback

Delta Media Server is designed first and foremost as a rock-solid, frame-accurate source of the highest quality media available.

Delta has been used in many of the world’s prestigious audio-visual attractions including theme park dark rides, digital planetariums, high-end theatre productions, mass audience live events, museums and visitor attractions.

Delta is frequently chosen for its uncompressed, perfect quality media playback allied with its flexibility in matching any display surface, whether flat, cylindrical, fulldome, half dome or 3D objects such as vehicle, building or odd-shaped screens.

Delta achieves frame-accuracy across multiple servers using Ethernet and genlock (hardware) based timing, necessary in blended projection systems where any temporal difference is easily noticed by the audience. Supporting multiple video (up to 16) and audio (up to 64) outputs per server dramatically lowers the cost of purchase, power consumption and rack space utilisation without compromising on quality of output – all outputs are uncompressed.

Delta’s range of servers also incorporates cutting edge playback, with hundreds of 4K and 8K media servers already fielded, our hardware design supports high resolution (8K x 4K and beyond) and high frame rate (up to 120fps) playback, coupled with the necessary real-time interaction necessary for our customer’s demanding system designs.

Live Capture

Delta Media Server supports capture devices as a source of media, allowing customers to show live camera feeds, captured imagery from other computers or streamed media from the internet.

Live capture resources act like any other visual media within Delta, so they can be sized, mixed, warped and have Delta’s many special effects applied to them.

Capture interfaces include;

  • SDI (1.5G, 3G & 12G)
  • DVI (Single & Dual Link)
  • HDMI (1.1, 1.3, 1.4, 2.0 supported)
  • sVideo / Composite
  • DisplayPort 1.2

Some capture devices, especially non-SDI interfaces, support custom EDID programming, which allows the operator to program non-standard capture resolutions which are particularly useful in dome environments – for example in fulldome planetaria or live events, the full-resolution fisheye media is often complemented by live capture from a real-time space simulation, and in this case the external space system is captured at high resolution (e.g. 4096 x 4096 @ 60fps) and placed on the fulldome canvas in fisheye mode.

The operator can then simply crossfade within Delta Media Server from playback media to the captured live simulation at any time.

Recording

Delta has two modes of recording content back out – non real-time recording is typically used to carve large media down to smaller parts for playback, for example an 8000 x 8000 fisheye movie can be recorded out to channel-specific movie for playback if it is too large to playback natively.

Non real-time recording is not suitable where there are live capture windows on the timeline as these will not be recorded out with a high enough frame rate.

Non real-time recording is also useful to minimise server load and essentially “flatten layers” down to a single movie for playback.

You can choose the output channel, output movie format, resolution and more in this mode.

Real-time (Preview) Recording is a separate, largely external control driven mechanism in which you pre-configure the record parameters (GUI – Config – Preferences – Preview), then start & stop the recording process from external control. The recording starts immediately and is real-time, so can record live capture windows to disk as well.

Real-time recording can take place simultaneously with playback, so for example, a live camera feed is mixed with playback content and the composition is recorded back to disk for later playback of the combined movie media/live camera feed.
