Overview GY-HC900CHE+KJ20 Lens Bundle (KJ20x8.2B KRSD-)
CONNECTED CAM 2/3-INCH BROADCAST CAMCORDER (LESS LENS)
CONNECTED CAM™ USHERS IN A NEW ERA OF QUALITY AND CONNECTIVITY
The GY-HC900 is a unique and innovative broadcast camcorder that makes no compromises in image quality while offering a level of connectivity not found elsewhere. It features three 2/3-inch CMOS image sensors that deliver high sensitivity, low noise and wide dynamic range. It's equipped with a new powerful communications engine that truly makes News-over-IP a reality with a streamlined ENG workflow that's both reliable and cost effective. And it offers a comprehensive fiber solution for advanced EFP and studio installations.
Important new features have been added to the GY-HC900 with the most recent firmware upgrade (v0300.) The camera now supports recording contribution quality ProRes HD422 files to SSD media via the optional KA-MC100 adapter. SSD recording can also be used in the backup mode. Live streaming is now much more efficient when using the HEVC/H.265 plug-in encoder (KA-EN200). High quality 4:2:2 10 bit streaming is now possible with H.265 at up to 24Mbps. Secure Reliable Transport (SRT) open streaming protocol is now available with this upgrade. And the camera now offers high quality broadcast graphic overlays, either lower third or full screen—a feature never before found on a 2/3-inch broadcast camera.

EXTRORDINARY CAMERA PERFORMANCE
The heart of the GY-HC900 is a production-quality imaging system that begins with a B4 mount lens. The camera adapts to a variety of lenses and automatically corrects for aberration. Three 2/3-inch CMOS sensors, combined with an F1.4 prism, produce full HD images with excellent sensitivity of F12 at 60Hz (extended mode) and a high SNR of 62dB (standard). JVC has paid particular attention to dynamic range and provides an HDR mode for expanded creative expression.
A 4-position optical filter compensates for a variety of lighting conditions. Positions are: 1 (clear), 2 (1/4 ND), 3 (1/16 ND), and 4 (1/64 ND).
MEMORY CARD RECORDING
Dual memory card slots are provided for standard SDHC/SDXC media. Flexible recording options include redundant, relay and backup modes. For contribution quality, the camera supports recording in the ProRes HD422 format to a plug-in SSD module (optional). The GY-HC900 also supports both the popular MPEG-2 35/25Mbps format, widely used by television broadcasters, and the more efficient .MOV H.264 format capable of delivering production quality 1080/60p 4:2:2 10-bit recordings. In this mode, recordings can be made at frame rates up to 120fps for ultra-smooth slow motion effects. The camera also records proxy resolution video clips for off-line editing or on-line posting.
ProRes 422 RECORDING TO SSD
Slide in an optional KA-MC100G SSD module, and record in the Apple ProRes 422 HD format. ProRes offers virtually lossless intra-frame compression and speeds up post production. The KA-MC100G accepts standard SATA M.2 SSD memory.
SSD memory can also be used for backup recording. While the Rec trigger is used to REC and STOP recording on one SD card (Slot A), the other SD card (Slot B), or "EXT" (SSD), can act as a continuous backup that overrides the pause function. A 2-terabyte SSD drive will provide over 50 hours of backup capacity when recording in the 70Mbps XHQ (.MOV) format.
THE INDUSTRY'S MOST CONNECTED CAMERA
JVC has taken connectivity to the next level with the GY-HC900. The camera incorporates a new processing engine that enables recording and low latency streaming, and simultaneous decoding for return video and IFB. Talent in front of the camera can engage in a 2-way interview with return video and audio while streaming live to air—all of this without any external boxes or backpacks. Depending on the mode, latency can be low for both outgoing and incoming video. Cellular bonding takes place with the optional snap-on SFE-CAM module, or with a Wireless LAN connection to one of our bridge units.
SRT (Secure Reliable Transport) is an open source video transport protocol that enables the delivery of high-quality and secure, low-latency video across the public Internet. SRT optimizes streaming performance across unpredictable networks with secure streams and easy firewall traversal, bringing the best quality live video over the worst networks. It accounts for packet loss, jitter, and fluctuating bandwidth, maintaining the integrity and quality of your video.
SRT provides end-to-end security, resiliency and dynamic endpoint adjustment based on real-time network conditions to deliver the best video quality at all times on any network.
SRT is built-in and can be dynamically adjusted for optimal stream performance and quality. Automatic Repeat Request (ARQ) is included with SRT. End-to-end 128/256 bit AES encryption makes sure your content is protected from contribution to distribution.
With firmware version v0300, the GY-HC900 streams using the highly efficient HEVC/H.265 compression format which delivers broadcast quality streams at 50% of the normal bitrate, or contribution quality 4:2:2 10-bit streams at higher bitrates. The optional KA-EN200 encoder is required for H.265/HEVC operation
The GY-HC900 is equipped with Multiple-Input Multiple-Output (MIMO) Wireless LAN technology for high speed, long range communications.
For studio and EFP operation, JVC offers the flexible FS-900 camera module which attaches directly without cables and feeds a 3-in-1 base station.
BROADCAST GRAPHIC OVERLAYS
With v0300 firmware, the GY-HC900 is now the first 2/3-inch camcorder to offer lower third and full screen broadcast graphic overlays. Graphics can be either added on-the-fly using a smartphone or tablet, or pre-loaded from an SD card. This feature allows the camera operator to generate live streams that include a television station logo, without using a separate character generator.

Take a more detailed look into the Canon KJ20x8.2B KRSD
Long portable affordable lens
The new KJ20x8.2B KRSD is a portable 2/3” HD Standard lens specifically designed to support low-cost image acquisition systems for a wide range of applications and users such as wedding and corporate videos, education films and documentaries.
At 8.2-164mm, the new KJ20x8.2B KRSD, covers a generous range of focal lengths. Along with the KJ20x8.2B IRSD, they are Canon’s widest lenses in the affordable 20x zoom class. MOD is 0.9M and the KJ20x8.2B KRSD comes equipped with a macro to allow closer subjects up to 10mm from the front of the lens. It also has strong rugged build qualities.
Outstanding Optical performance
The servomotor has a noise-suppressing construction to ensure there is no corresponding increase in noise. The newly developed advanced drive unit includes an interface function for chromatic aberration compensation. The Memo switch on the drive unit, which sets specific zoom positions for the Shuttle Shot function, has been changed to a push switch. The memo switch enables more reliable Shuttle Shot setup in the field where more consistent functioning of the controls is required.
The outstanding optical performance of Canon’s new KJ20x8.2B KRSD portable HD lens is the result of the company’s world-leading design tools, including cutting edge optical simulation and 3D design technologies, novel optical glass materials and coatings and extraordinary dispersion glass.
Newly Developed Advanced Drive Unit
Together, these technologies and materials have produced an outstanding combination of cost-effectiveness and performance in the KJ20x8.2B KRSD. The lens has minimised axial, and lateral chromatic aberrations, which can be reduced further with ‘the chromatic aberration compensation function’ that is built-in to the Drive unit. Coma aberrations and geometric distortion are well controlled. The new optical materials and multi-layer optical coatings used in the lens effectively lessen the ghosting.
The KJ20x8.2B KRSD also has a high MTF (modulation transfer function) at the picture centre that is well controlled right out to the picture extremities. The KJ20x8.2B KRSD ’s optical performance is well-balanced for both near and distant subjects, surpasses previously available lenses in this price range.
