Chapter 1 Overview Uncompressed PCM recording of 24-bit 48 kHz audio enables 8-channel audio recording at high sound quality. 1) MPEG HD422 is a trademark of Sony Corporation. Long recording times PDW-F1600 or PDW-HD1500 supports dual-layer Professional Discs (50 GB). When dual-layer Professional Discs are used, this unit can record about 95 minutes. Recording and playback functions Support for multiple SD1) and HD codecs In addition to the MPEG HD422 codec, this unit supports the MPEG HD codec.2) It can record HD 4:2:0 digital component files at both 1080i (35/25/18 Mbps3)) and 720P (35/25 Mbps), allowing HD operation across a wide range of recording times and application objectives. The unit is also capable of SD (IMX 30/40/50 Mbps or DVCAM codec) recording and playback. 1) HD1500 When the PDBK-S1500 or PDBK-F1500 option is installed. 2) MPEG HD is a registered trademark of Sony Corporation. 3) Playback only supported for 18 Mbps. Support for multiple frame frequencies This unit can record and play multiple frame frequencies at both 1080 (59.94i, 50i, 29.97P, 25P, and 23.98P) and 720 (59.94P and 50P) (for MPEG HD422). It can also perform pulldown playback of discs recorded at 23.98P. 1) 1) HD1500 When the PDBK-S1500 option is installed. Support for mixed format recording mode As long as the frame frequency group is the same, clips in different recording formats can be recorded or written to the same disc. 1) The system frequencies supported by this unit are divided into frame frequency groups, as shown in the following table. 1) The recording format is regarded as different whenever the system frequency, video resolution, video codec/bit rate, or number of audio channels or number of bits does not match. Frame frequency group 59.94Hz 50Hz 23.98Hz System frequency 59.94P 59.94i 29.97P 50P 50i 25P 23.98P You can record clips with different recording formats, for example HD422 and HD420SP clips, by putting this unit into mixed format recording mode. Note Continuous playback may not be possible at the transition point between two clips with different recording formats. Linear editing Using this unit as the recorder, you can perform insert and assemble editing of recorded clips. 1) 1) HD1500 When the PDBZ-UPG02 Software Upgrade Key is installed, you can perform timecode editing only. SD upconvert function The unit can output HD signals while playing discs recorded as SD, allowing SD material to be utilized in an HD environment. 1) 1) HD1500 When the PDBK-S1500 or PDBK-F1500 option is installed. HD downconvert function The unit is provided with a downconvert function. HD disc playback signals can be downconverted to SD signals and then output as SDSDI or composite signals. This allows you to use SD nonlinear editors and monitors for editing and program output. 1080/720 cross-conversion This unit supports cross-conversion output. It can output 720 while playing discs recorded as 1080, and output 1080 while playing discs recorded as 720. HDSDI remote recording HDSDI connections can be made to camcorders with remote HDSDI support (PDW-700 XDCAM HD422 camcorder, HDW-730/730S/750/790/F900R HDCAM 1) camcorders) to enable recording synchronized to REC and STOP operations on the camcorder. 1) HDCAM is a trademark of Sony Corporation. Clip Continuous Rec function Normally, a clip is generated as an independent file every time recording starts and stops. The Clip Continuous Rec function allows you to continue recording to the same clip until the function is stopped or turned off, regardless of how many times recording starts and stops. This is convenient if you want to avoid generating a large number of short clips, or if you want to record without worrying about the limit on the number of clips (maximum 300). Note This function is available only when you are operating equipment connected to the REMOTE(9P) or SD/HDSDI INPUT connector. It is not available on the front panel. Recording of proxy AV data Proxy AV data is a low-resolution (1.5 Mbps video, 64 kbps per audio channel), MPEG-4 based version of a full resolution data stream. Whenever this unit records full resolution MPEG HD422 data, it simultaneously generates and records low-resolution proxy AV data. Because of its 12 Features
