DVCAM and DV Format Playback The DVCAM digital recording format for video professional is an extension of the consumer DV format. Therefore, it maintains playback compatibility with the consumer DV recordings and has the advantage that both standard and mini cassettes can be used in the same machine. Analog Inputs and Outputs The DSR-85 provides a full complement of analog I/O for video and audio, which offers compatibility with conventional analog equipment, such as Betacam SP™, Hi-8™, and S-VHS for a smooth and gradual transition to digital systems. For video, composite, component and S-video connections are provided. Four channel or two channel (selectable) inputs and outputs are provided for audio. High Speed Picture Search The DSR-85 offers high speed picture search which provides a recognizable picture at various speeds over a range of up to 32 times normal speed, in both forward and reverse, to quicken editing operations. Jog Audio Complete reproduction of four channels or two channels of digital audio is achieved 1/30 to 1 times normal playback speed, both in forward and reverse, in the JOG mode. This feature is helpful for quickly and precisely designating editing points while monitoring the digital audio signals. The audio data is held in the memory and output according to search speed for enhanced recognition. Digital Slow Function The Digital Slow function takes advantage of digital processing for playback 0 - +1/5 times normal playback speed both in forward and reverse, realizing noiseless slow-motion images with picture quality on par with dynamic tracking playback. Either frame or field accurate playback is possible. Self-Diagnostics and Error Log Should an error be detected, an error message will be displayed which will identify the problem area. In this way, down-time can be minimized. Moreover, the error log function makes it easier to detect the error by retaining the past status data of the DSR-85 in memory. SDTI (QSDI) I/O connectors The DSR-85 is equipped with a QSDI interface which handles compressed video, as well as, sub code data and digital audio signals of the DVCAM recording format. The QSDI interface allows degradation-free transfer of both video and audio signals. When integrated into the nonlinear editing system with the ES-7 EditStation system, the DSR-85 is capable of four times normal speed data transfer via the QSDI interface. Serial Digital Interface (SDI I/O) The SDI (Serial Digital Interface) which conforms to the SMPTE 259M broadcast standard, is supported by the optional DSBK-120 SDI I/O Board for simple connection with SDI equipped devices such as Digital BETACAM™ VTRs. Built-in SMPTE Time Code Generator/Reader A built-in time code generator and reader are in the DSR-85 to offer precise video editing. The time code conforms to the SMPTE standard. Time code written in the sub code is controlled via the RS-422A interface port. Input/output of time code is possible with the optional DSBK-130 Time Code Input/Output Board. Time Base Corrector The DSR-85 is equipped with a built-in time base corrector for all analog outputs giving highly stable video signals. Sync and SC phase adjustment is made from the front panel, while the TBC control is possible with the optional UVR-60 TBC Remote Control Unit. DVCAM Component Digital Recording Format The DVCAM format uses 8-bit component digital recording with a 5:1 compression ratio and sampling at the rate of 4:1:1 to provide superior picture quality and multi-generation capability. The DVCAM format employs an intra frame compression scheme which is ideal for editing applications. Based on DCT (Discrete Cosine Transform) techniques, each frame consist of 10 tracks. Each track has ITI (Insert and Track Information), Audio, Video, and sub code areas. The ITI, which is a reference signal for a precise tracking and Time Codes on the sub code area assure highly accurate editing performance. This technique provides much greater operational flexibility and complex multi-layering. High Quality Digital Audio The DSR-85 provides two selectable audio channel modes, two channels and four channels. In order to ensure superb audio performance with a wide dynamic range and an excellent signal-to-noise ratio, the PCM (Pulse Code Modulation) digital stereo recording system is used in both modes; 2CH of 16 bit, 48kHz sampling frequency and 4CH of 12 bit, 32kHz sampling frequency. ClipLink Operation The ClipLink system is a comprehensive data management system of the shooting information which is necessary for the total digital production process, ranging from acquisition to editing. Incorporated into Sony DVCAM cassettes is an IC memory chip which holds shot list information, called ClipLink Log Data. When the cassette is loaded into the DSR-85, the ClipLink Log viewing of the images on the GUI (Graphical User Interface) screen before actually being recorded onto the hard drive. Then only the selected clips on the SUI screen may be uploaded for time and space-saving of efficiency of the hard drive. When integrated into the ES-7 EditStation nonlinear editing system, the DSR-85 executes high-speed transmission of the selected ClipLink data at four times normal speed, at which time the actual editing work can be started immediately. When combined with the ES-7, unprecedented productivity can be brought into the editing process. Remote Control Via RS-422A The DSR-85 is equipped with an RS-422A serial communication port to interface with Sony VTRs and editing controllers such as the PVE-500. In addition to VTR control functions, the interface also enables the transfer of ClipLink Log Data from the cassette memory in the DVCAM cassette to a Sony EditStation system. Frame Accurate Editing Capability When connected to RS-422A equipped editing controllers, the DSR-85 functions as an editing recorder for assemble or insert editing. Frame accurate editing is assured in both modes, thanks to the sophisticated servo control and built-in time code generator/reader. In the insert mode of the DSR-85, video, audio and time code can be inserted independently or in any combination, In the assemble mode, all of the prerecorded signals (video, audio, and time code) are erased and replaced with new signals.
