Recording in SD provides a time-saving alternative to down-conversion of HD material for SD broadcasts, which is still an industry standard in many countries worldwide. Standard Definition Recording Capability Responding to the needs of the industry, the GY-HM790, in addition to its capability as an HD recorder, offers standard-definition recording for maximum flexibility. This capability makes it possible to record slow or fast motion when the recording is played back at 24p or 30p. ![]() Variable Frame Rate Recording (Overcrank, Undercrank) When recording in the 720p 35Mbps mode, the camera can be set to record at a frame rate different than the playback rate. The SP mode records at a constant bit rate of either 19.7Mbps or 25Mbps to ensure compatibility with a wide range of equipment. In the HQ mode, the encoder operates with a variable bit rate average of 35Mbps. This results in recorded images of exceptional quality. JVC Original 35Mbps MPEG2 Encoder Drawing from its experience in developing rack mount encoders used by major television stations, JVC developed a proprietary codec capable of providing highly efficient compression up to 35 megabits per second, a bitrate that can support full 1920 x 1080 sampling. JVC's advanced ProHD capture technology incorporates a new patent-pending Adaptive Pixel Correlation Technique (APCT), and combined with TRIPLEX Offset Technology delivers exceptional resolving power comparable to cameras with larger image sensors. Performance Advanced Technologies = Higher HD Image Quality The GY-HM790 utilizes three precisely aligned 1/3" progressive scan full HD CCDs-one each for red, green and blue primary colors-and outputs full resolution in both 720p and 1080i/p. JVC's VF-HP790 is an 8.4" high resolution LCD viewfinder with a digital interface to the camera. In a studio configuration, the GY-HM790 can be handheld or easily fitted with the KA-790 sled, a sleek and functional housing that supports a studio viewfinder, teleprompter and large lens if desired. Other modules include the KA-F790 Remote Fiber Adapter, the KA-AS790 ASI Module, and the KA-MR100G SxS memory card recorder. Power, camera control, intercom, tally and a fully digital HD signal path are available through the RM-HP790 CCU. The KA-M790 multi-core studio interface module offers a 26-pin interface compatible with cables from JVC and Sony to connect with a camera control unit (CCU). Modular Design The GY-HM790 is equipped with a 68-pin chassis connector that allows various modules to be attached to the unit without external cabling.
