Video Rendering Platform

The foundation of Orad’s real time graphics solutions is the family of HDVG hardware platforms which meets the specific needs of the broadcast industry.

The HDVG Concept
Orad’s HDVG platform answers all of the requirements for today's broadcast graphics rendering platform. Based upon standard high quality PC components, the HDVG provides a reliable, real-time operating system environment with genlocked SDI graphics and video outputs. The HDVG’s multiple SDI outputs can be used in different broadcast standards simultaneously, as well as program and preview, all from a single system. Multiple low-latency (2 frame delay) SDI video inputs can be freely manipulated and mapped onto any 3D objects as if they were ordinary pictures. The built-in clip player can handle multiple video clips up to 4K resolution, any frame rate (independent from the video output rate) and with a wide variety of codecs.

Embedded audio is available for all Master Control Room and channel branding needs. The built-in linear keyer support pre-multiplied graphics and can be equipped with a mechanical bypass and a “soft bypass” for system component failure. Redundant power supplies and RAID 1 for the system’s disk complete the HDVG’s failover protection. All this comes as standard in one compact rack-mount box.

At the heart of the HDVG family lies Orad’s HDVG I/O board. Unlike other I/O boards, the HDVG board was designed for real time graphics and establishes a direct connection between the I/O board and the graphics board, eliminating the need for graphics read backs through the motherboard. By doing so, the HDVG board frees significant system resources, resulting in faster rendering, the ability to manipulate multiple video inputs, video clips, and more.

The HDVG is available across Orad’s entire range of real time graphics solutions including its ProSet virtual studio, Maestro graphics suite, 3DPlay channel branding system, Morpho character generator, MVP sports enhancements, Interact interactive graphic system, TD Control and PowerWall, Orad’s video wall display system.

Ranging from the entry level HDVG2 to the powerful high-end HDVG4, Orad has a graphics rendering platform to suit any production requirement and budget.

HDVG4 – Orad’s avant-garde graphics rendering platform
Orad's top of the line graphics rendering engine, the HDVG4, is a 64-bit rendering system that offers many features unique to Orad, including the ability to input and output the broadcast signal in different formats simultaneously, providing true dual channel capabilities without performance degradation, and up to 16 output channels for video wall users; support for UltraHD, 3G (1080p) and 3DTV (stereovision); SNMP for system monitoring; video and audio functionalities including native support for LTC, multiple mixing sources, and more.

Superior graphics capabilities
The HDVG4 offers two cutting edge (Nvidia) graphics boards, both of which are connected to the same HDVG board enabling “internal chaining". This allows both graphic boards to work simultaneously, providing either very high resolution output (up to 8 outputs at 1080p (3G) or 16 outputs at 1080i) for video walls, very high antialiasing (16 x) or true dual channel output from a single box without a loss of performance (quad channel is also available as an output option with reduced performance).

The HDVG4 offers many types of output options including; 16 physical outputs, cross format, UltraHD, 3DTV and video wall configurations.

Cross format options allow for the simultaneous output of SD and HD. In SD, it is possible to produce two outputs in 16:9 and 4:3 at the same time. This removes the need to place additional up / down converters after the graphics system to deal with cross format broadcasts.

UltraHD is supported either with internal mixing over 4x 3G inputs, or with dedicated Fill and Key outputs for external keying.
HDVG4 enables 3DTV outputs using HD or HD 3G formats. HDVG4 supports LR independent or side-by-side.
For video wall environments the HDVG4 enables broadcasters to output HD SDI at up to 16k resolution at 1080i or 8k at 1080p (3G) from a single system, giving unrivalled rendering capabilities without graphical tearing.

There are up to 4 internal video mixers (linear keyers) or chromakeyers available; each of them can mix graphics with different backgrounds, allowing quad channel playout from a single HDVG4.
There is a separate video delay available in each of the mixer sources, which is especially important for squeeze backs and cuts.

The HDVG4 supports up to 16 HD SDI or 8 3G inputs as video sources, backed up with an internal RAID 10 array for clip playback.

HDVG4 runs on the virus free Linux operating system and for redundancy offers hot swappable dual power supply, mechanical and software bypass, and a RAID based system disk.

HDVG+ Orad’s widely used rendering platform
The HDVG+ is a native 64-bit system which offers significant processing and rendering power enhancements in a 3 rack unit chassis. As a successor to Orad’s widely adopted HDVG platform, it provides high level rendering with a variety of video I/O options.

Reliability and powerful capabilities
Taking advantage of the HDVG I/O board, the HDVG+ can introduce up to 12 live video feeds into the graphic scene in SD and up to 6 in HD, as well as playback a wide range of video clips in different formats and resolutions. Additionally, it is equipped with an embedded downstream keyer, video delay and 16 channels of embedded audio support. The HDVG+ runs on the virus free Linux operating system and for redundancy offers hot swappable dual power supply, mechanical and software bypass as well as RAID protected storage.

HDVG2 – Cost effective digital video graphics rendering platform
The HDVG2 is Orad’s cost effective, all in one digital video graphics rendering platform. The HDVG2 is designed to meet the real time graphic rendering needs of the broadcast industry. The HDVG2 is a HD / SD system, supporting all existing SD and HD formats which can be configured as an HD system or as an SD system. Additionally, the HDVG2 can initially be configured in an SD configuration, and when upgrading to HD is considered, the configuration changeover is smooth as silk and easy.
This compact 2U platform comes in three different configurations: single channel with one control PC and a Linux based render engine; dual channel with two Linux based render engines and without a control PC; and single channel with dual power supply, which comes with one Linux based render engine and dual power supply.
