JVC cameras have become the standard for fast paced ENG leading the industry in on-board streaming and IP connectivity. The GY-HM660 is JVC's latest and most advanced handheld mobile news camera. Small and light enough to be used anywhere, this camera surpasses the performance of many traditional ENG style units and offers reliable, high quality streaming without the use of a backpack or external encoder. Dual codecs make it possible to record full HD on solid state memory and at the same time stream the footage for live broadcast.
The GY-HM660's long (23x) wide angle lens is perfect for fast paced ENG. The camera offers superb low light performance with F12 sensitivity at @2000 lux
The GY-HM660 has JVC's latest streaming engine employing Zixi or SMPTE 2022 forward error correction (FEC). And it's the world's first camcorder with a built-in IFB audio channel. Zixi advanced streaming is included and provides forward error correction, automatic repeat request, and adaptive bitrate control. Multiple Zixi enabled cameras are easily managed with the optional ProHD Broadcaster (BR-800). The camera also provides an RTMP stream for content delivery networks such as USTREAM and YouTube. Transmission at selected resolutions, bitrates and formats is possible independent of the recording mode. Stream 1920 x 1080 (3, 5 or 12 Mpbs), 1280 x 720 (1.5 or 3Mbps) or 480i (0.8, 0.2 Mbps).
Multiple encoding formats:
- HD MPEG2 (35/25/19Mbps)
- AVCHD 1920x1080 60i
- 1080/60p recording capability
- SD H.264
- 480x270 H.264 (web)
- 960x540 H.264 mode
Wide media format compatibility:
- .MXF with rich Metadata (optimized for asset management)
- .MOV (Final Cut Pro)
- .MP4 (XDCAM EXTM)
- AVCHD with additional lower bitrate AVCHD modes
The GY-HM660's long zoom range means that you can get shots not possible with other cameras its size.
For a wider angle of 23—533mm, JVC offers the HM600WC8X72HU wide angle adapter. The built-in Optical Image Stabilizer (OIS) helps to correct lateral and vertical movement of the camera, ensuring that pristine HD images remain sharp and stable.
ADVANCED PROCESSING ENGINE
The GY-HM660 further provides the H.264 Ultra High Quality (UHQ) 35Mbps recording mode, again offering superior image quality but with smaller file sizes.
FLEXIBLE FILE-BASED WORKFLOW
It is possible to start editing footage from one card while still shooting to the other. With simultaneous recording, you can easily create backup or duplicate files as you shoot without the need for any external equipment—either for a client copy or simply for peace of mind. Additionally, while the Rec trigger is used to pause and unpause recording on one card, the other card can act as a continuous backup that overrides the pause function. With the new dual codec, it is now possible to record full HD files on one memory card while simultaneously creating smaller SD or proxy files on the other, providing the flexibility for a range of workflow possibilities.
SDHC/SDXC media offers the best combination of price, availability, capacity, reliability and transfer speed. With no moving parts and no pins or other extrusions, SDHC/SDXC cards are both durable and reliable, and compare favorably with tape on a cost-per-minute basis.
* During simultaneous backup recording in HD mode, the duplicate file records in the same file format and bit rate as the original.
WI-FI AND BROADBAND CONNECTIVITY
You can download a metadata settings file (XMLformat) from a remote FTP server and store metadata inthe GY-HM660 for recording onto video clips in the MXF format. Metadata may include TITLE (2 data fields), CREATOR, and DESCRIPTION (up to 2047 characters.) Once stored in the camera, metadata is then recorded into the MXF video clips, and will stay with the clips through postproduction, playout and archiving.
In addition to downloading, metadata is added in the field using a smartphone, tablet or PC via the camera's web interface. Again, the camera records this information to the MXF video clips.
Metadata on existing clips may be edited using a smartphone, tablet or PC. Using a web browser, the "Clip Metadata" screen displays a list of clips stored on the memory card with thumbnail images. Clip metadata can be edited and rewritten back to individual clips stored in the camera.
Remote control and viewing with a mobile device
When using an optional WiFi or LTE adapter, you can access many of the camera's settings with a tablet, smartphone or computer giving you unprecedented remote control capabilities. Best of all, no "app" is necessary as everything is accessible using a standard web browser. The image from the camera may be also viewed independently of any streaming or recording, allowing the operator to make lens and camera adjustments live. While viewing the image, the camera's recording and streaming functions can be stopped and started and the zoom lens may be controlled. Zoom presets are also registered and deleted remotely using the web browser.
Unwanted information may be trimmed from clips with basic in-camera editing, creating shorter files for transfer. FTP transfers may be performed in the background, allowing the operator to continue shooting without interrupting the workflow. Secure FTP transfers are also possible using SFTP or FTPS protocols.
In addition to secure FTP, the following WiFi security protocols are supported:
8 - 63
The GY-HM660 outputs a transport stream with TCP or UDP protocol to a decoder or computer with a fixed IP address at the receiving facility. Latency is minimal (usually under 2 seconds with UDP transmission.) Image quality is dependent on the speed/mode selected. With a good 4G, WiFi, or wired connection, additional error correction may not be necessary making this the easiest and most economical streaming solution with the lowest latency. SMPTE 2022 1/2 forward error correction (FEC) is provided for use when network conditions are more challenging. Latency is slightly increased when FEC is used.
Advanced streaming with Zixi ARQ and Zixi Forward Error Correction
JVC's advanced streaming technology, powered by Zixi, utilizes content-aware error correction algorithms to compensate for packet loss common with mobile internet connections. In this mode, the decoder performs a dynamic assessment of the link capacity (link monitoring) and signals the camera to adjust bitrate and, if necessary, resend packets. The advanced error correction is able to compensate for up to 50% packet loss (in the new high reliability mode) assuring a reliable stream even under adverse conditions. A Zixi-licensed decoder or server is required at the receiving end.
High speed streaming at 12 Mbps UDP (or 5 Mbps, Zixi) is now possible for production quality results. It is also now possible to stream directly to a content delivery network (CDN) such as USTREAM thanks to the implementation of RTMP protocol. This makes it possible to stream directly to a worldwide audience at the touch of a button, and without any additional hardware in the field, except a modem!
ProHD Broadcaster Powered by Zixi / Cloud-based Services
Single camera point-to-point streaming to a single decoder delivers excellent results. For facilities with multiple cameras, JVC has made available the ProHD Broadcaster, the centerpiece for high quality IP video over the internet. Broadcaster is available as a physical server or cloud-based solution, and receives streams from JVC's streaming ProHD cameras and delivers those streams to various decoders and content delivery (CDN) ingest points. Broadcaster includes a wide array of video processing features, including transcoding, time shifting, VoD playout, recording functionality and stream switching. Whether phyically located on premises or in the cloud, Broadcaster offers a friendly web interface that simplifies management of multiple sources and stream destinations while providing advanced content-aware correction compatible with Zixi-enabled JVC cameras.
When directly connected to an LTE modem or WiFi hotspot, the GY-HM660 provides active feedback to the camera operator with indications in the viewfinder (and LCD screen) about the status of the stream and LTE (or WiFi) connection.
USER FRIENDLY FUNCTIONS
An HDMI connector outputs the same signal as the HD-SDI connector, especially useful for monitoring while shooting a live event. The HDMI output may be switched to RGB mode when monitoring via computer.
The side panel is equipped with screw mounts to attach a bracket (CA-UP600) for an optional wireless receiver. Dedicated mic and headphone jacks are provided for this purpose. An 3.5mm audio headphone jack provides monitoring of the camera's audio channels or the decoded IFB audio channel.
