Connectivity, HD/SD SDI Output | JVC Gy-hm700 manual

Uncompressed Audio with Manual Controls

The GY-HM700 records 2 channels of uncompressed LPCM (lin- ear pulse code modulated) 16 bit audio sampled at 48Khz. Audio levels can be controlled manually, or

automatically using AGC. An audio meter is provided in the LCD and VF dis- plays to facilitate adjustment. Balanced XLR connectors are provided on the camera for an external microphone and/or wireless receiver. 48V phantom power is available for each microphone. Versatile input switching allows the

m i c r o p h o n e signal to be

directed to the desired channel. A shot- gun microphone is provided with the GY- HM700U.

Connectivity

HD/SD SDI Output

For live broadcast applications, or for monitoring, the GY- HM700 provides an uncompressed, 4:2:2 full HD signal via its HD/SD SDI connector in any HD mode.

The HM700 also allows the camera operator to deliver a standard definition SDI pool feed or microwave feed while recording to the SDHC card in full high definition. The SDI signal can come from either the live camera or from memory playback. When 24p modes are selected, the signal will contain Varicam™ (720p24 only) flags to facili- tate post production. The downconvert-

ed video may be in either PAL or NTSC depending on the HD mode selected: 60Hz (24p, 30p, 60p/i) = NTSC, 50Hz (25p, 50p/i) = PAL. It is also possible to output the menus and clip viewer via the HD/SD SDI output.

Component or Composite Video Output (selectable)

Component HD signals can be output via the BNC connectors on the camera. The signal will always be in the format being captured

or played back. (Cross converting to another format is not possible.) If a downconverted composite signal is desired, the output can be switched to provide NTSC (when HD is 24p/30p/60p/i) or PAL (when HD is 25p, 50p/i) signals. Downconverted composite signals can be especially useful when providing an SD feed for a live webcast while simultaneously recording full HD. The composite output can also be provided when playing back recorded high definition mate- rial.

Simultaneous DV/HDV Output via

IEEE-1394

Downconverted standard definition DV signals are available through the 4-pin IEEE-1394 connector. These signals can be recorded on most "Firewire" recorders, including the DRHD100GB100 dockable HDD recorder. Again, these signals will be in either the NTSC or PAL mode depending on the HD mode selected (60Hz or 50Hz) and can be output while recording full high definition to the built-in SDHC memory cards, or when play- ing back HD material. When an SP high definition mode is select- ed (either 19.7Mbps or 25Mbps), the camera can also output an HDV transport stream compatible with the DRHD100GB100 through the IEEE-1394 connector.

Remote Camera Control Connector

A 6-pin remote connector provides a TTL interface to an optional JVC RM-LP25U, RM-LP57U, or RM-LP55U control unit. Extensive control options are available including shading, paint, iris, gamma level, knee, gain, shutter and black level. Functions vary with each unit.
