RTD 4224 Real Time Disk


The Premier Digital Disk Recorder for Post Production

The RTD 4224 Digital Disk Recorder combines a wide range of features with superior 10-bit uncompressed digital image quality to meet the high demands of on-line digital post production editing and real-time compositing. Optional features such as the unique Smooth Motion® and the Second Channel option further enhance the capabilities of RTD. Besides on-line editing applications, the RTD is also an ideal capture and play device for telecine suites, graphics, animation, and paint systems.

10-BIT DIGITAL VIDEO / 24-BIT DIGITAL AUDIO

To maintain video recordings with the highest resolution possible, the basic RTD 4224 system records incoming video with 10-bit resolution, in 4:2:2 digital components. With the optional second video channel installed, the RTD may be easily configured by the operator to record 10-bit 4:4:4:4 RGBA digital video, conforming to ITU-R/BT.799-2 specification. And with the Digital Audio option installed, the RTD can record up to four tracks (two stereo pairs) of 24-bit, 48kHz AES/EBU digital audio. These levels of video and audio resolution ensures the highest possible quality.

RAVETM WITH AXIAL EDITOR

Combining the RTD 4224 disk recorder with the Axial 2020 or new Axial 3000 On-Line Editing Systems from Accom provides a level of control never before accomplished with any other disk recorder. With the RAVE software, the Axial editor has direct control over the RTD segment play and other transport functions. This feature credits the Axial as the only editor capable of fast and efficient non-linear editing in the on-line editing environment. Accom's term for this process is RAVE: Random Access Visual Editing.

CINE PLAY

The "Cine Add" feature imparts the "3:2 pull-down" sequence in real time, during disk playback. Graphics may be rendered and telecine transfers performed at 24fps, and then played at 30fps with Cine Add, saving a great amount of rendering and transfer time.

The "Cine Remove" feature performs the opposite operation of Cine Add. Video material containing the "3:2 pull-down" can have this sequence removed during real time play back. This makes life much simpler for rotoscoping applications and slow motion playback. Without removing the 3:2 sequence, slow motion playback will appear 'jittery'. With Cine Remove, the 'jitters' are easily eliminated. This removal also operates during single-frame jog operation, allowing easy rotoscoping operation.

OTHER STANDARD FEATURES:

Non-Linear Segment Play This feature easily rearranges the order of scenes on the disk, without the need to make new recordings. Each segment contains play speed and output mode. A segment editor is included in the standard in RTD.

Macros Complex control panel operations can be memorized and then executed automatically. All macro sequences are saved in non-volatile memory within RTD, and can be triggered from GPI.

525/625 Operation A press of a button switches the system to operate in either the 525 or 625 line standard. The system can also sense the line standard of the incoming reference, and prompt the user to switch to appropriate line standard.

Timecode Offset By default, video and audio material is addressed according to internal disk timecode starting at zero. If desired, a timecode offset may be applied to the recorded material.

SCSI Archive & restore to an Exabyte 8mm tape drive in TAR format, or the former defacto "Abekas" format. This port can also be used as a SCSI Target for a host computer, enabling transport control and image transfers to and from the host computer.

Ethernet Image transfer and comprehensive transport commands are available from host computer systems. Standard TCP/IP protocols are supported, as well as UNIX remote copy (rcp) commands.

GPI Four input and four output General Purpose Interface triggers are provided per video channel. GPI Inputs trigger all transport control functions, or any macro sequence. Output GPIs supply a trigger to an external device, triggered either as a macro step or at a specific playback timecode.

RS422 Each video channel features two RS422 serial control ports, supporting both Sony and SMPTE protocols. These ports are used to slave the RTD system to an external editing system or other controller.


DUAL VIDEO CHANNEL / DUAL USER

Adding the second video channel to the basic RTD 4224 produces an extremely flexible system. This option provides a second digital video I/O, along with a second set of RS422 editor and GPI input/output ports. The disk storage for the second video channel is independent from storage on the primary channel, thus providing simultaneous record and play capability for real-time digital compositing (layering).

A dual-channel RTD 4224 is also easily partitioned for two simultaneous users, providing each user with completely independent control. It's just like two disk recorders in one! When the need arises, the RTD is easily reconfigured for single-user operation at the touch of a button, placing all of the video disk storage onto a single video channel.

4:2:2:4 YUV WITH KEY / 4:4:4:4 RGB WITH KEY

Configuring the dual-channel RTD for a single user provides precise record or play of two video signals in tandem. This user may record or play 4:2:2:4 YUV video with key in one machine. Likewise, the user may record 4:4:4:4 RGB video with key (RGBA). All in superior 10-bit resolution. Further, this RTD configuration requires only one serial control port from an external edit controller. Traditional VTRs and other DDR systems require two separate machines to achieve this task an expensive, difficult to control and hard to manage approach.

SMOOTH MOTION

A common problem in editing facilities is obtaining smooth slow motion playback, free of jerky movement. Prior to the arrival of the RTD 4224, smooth slow motion was accomplished by an extremely time-consuming, non real-time process of "expanding" the video. With the Smooth Motion option, this "smoothing" process can take place in real time during disk playback, without the need for a target recording elsewhere on disk. The Smooth Motion process creates intermediate fields during slow motion playback, eliminating picture content stutter and jerking normally found in off-speed video tape and DDR play back.

The RTD's Smooth Motion option also features advanced image enhancement facilities, such as Image Strobe with Averaging; Image Blur; and Digital Noise Reduction. These additional features not only operate on the off-disk playback, but can also be applied to 'bypass' video feeding through the system.


EXTENDING VIDEO RECORDING TIME

The basic RTD 4224 comes standard with 32 seconds of 10-bit, uncompressed 4:2:2 digital video record time. This 10-bit uncompressed recording time may be increased in 32-second increments, to a maximum time of 7 minutes, 48 seconds by adding additional disks to the system.

CHOICE OF AUDIO OPTIONS

Analog Audio with 'scratch' quality, or Digital Audio with full 48kHz AES/EBU quality can be ordered with the RTD system. In both options, audio is stored on a disk separate from the main video disks, with a standard recording time of 15 minutes. This separate disk provides the capability to perform audio edit inserts which are independent from the video material. This is a feature not possible on DDR systems which record audio multiplexed with the video onto the disk.
