Panasonic AJHD1400 AJHD1400 User Guide - Page 6

Introduction This unit is a multi-format VTR capable of recording and playing back HD signals (1080i/59.94 Hz, 1080i/50 Hz, 720P/59.94 Hz, 720P/50 Hz) in DVCPRO HD-LP format using a small cassette tape 1/4 inch wide, HD (DVCPRO HD/DVCPRO HD-LP*) and SD (DVCPRO50/DVCPRO) recorded in DVCPRO format as well as conventional consumer DV/DVCAM tapes. A down-converter as a standard feature verifies all tapes using analog composite signals and SD SDI output. Similarly, each of the following output signals can be obtained. z 720/25p over 60p sources can be converted to 1080/25 PsF or 576i format output signals. z 720/50p over 60p sources can be converted to 720/50p, 1080/50i or 576i format output signals. The compact size and light weight of the unit enable it to be carried around and mounted in a standard rack with ease. You can perform the unit's settings interactively with the onscreen menus displayed on the TV monitor. * DVCPRO HD-LP has the same format as the DVCPRO HD EX described in the operation manual of our camera recorder. Features Compact size and light weight The unit has a width of 214 mm (8-7/16 inches), a height of 132 mm (5-1/4 inches), and a depth of 442 mm (17-3/ 8 inches) (Protruding portion is not included), and weighs only 8.5 kg (18.74 lb). Grips are also attached for easy carry. Efficient installation in a rack The unit's width is one-half of 19 inches and its height is 3U: this translates into greater saving of installation space in a standard rack compared to conventional models. DVCPRO HD cassette tapes used The unit uses 1/4-inch wide cassette tapes. When recording HD signals, use DVCPRO HD cassettes. High image quality The unit achieves a high image quality by recording 4:2:2 HD component signals with a recording rate (=100 Mbps) which is four times as high as that for existing DVCPRO formats. 1080i or 720p, NTSC or PAL selectable By switching the settings provided for the video signal input (1080i/59.94 Hz or 720p/59.94 Hz) on the setup menu, the unit can record and playback each signal and also playback NTSC SD material. The unit also supports the PAL mode. Playback of 1080i/50 Hz, record and playback of 720P/50 Hz or playback of PAL SD materials is enabled by switching the setting on the system menu. Frame rate conversion When playing back a tape recorded at a frame rate of 24 fps using a variable frame rate camera, the tape's signals can be converted to the 1080/24 PsF format and output by selecting a menu item setting. When playing back a tape recorded at a frame rate of 25 fps, the tape's signals can be converted to the 1080/25 PsF or 576i format and output. When playing back a tape recorded at a frame rate of 50 fps, the tape signals can be converted to the 1080/50i or 576i format and output. z Use tapes that are shot with a variable frame rate camera. z Do not use dubbed or edited tapes. The tape control information may be lost, making it impossible to convert the signals for playback. DVCPRO-compatible playback In addition to DVCPRO HD-LP playback, the unit can play back tapes recorded using the existing DVCPRO HD, DVCPRO50 and DVCPRO formats. It can also play back consumer DV tapes (SP) and DVCAM tapes. SD down-converter The unit comes with a built-in SD down-converter as a standard feature to enable the output of SD SDI signals and analog composite signals at the same time as HD SDI output signals and for monitoring the signals on an SD monitor. Up-convert function When an SD format tape is played back, it is possible to output the signals in the HD SDI output and HD analog component signals while at the same time outputting them in SD format, since this unit includes the HD converter as a standard feature. 6
