Bringing a New Level of Functionality and Robustness to HDV Productions
– the HVR-1500 HDV Recorder
The HVR-1500 is an HDVTM source feeder/ recorder*1 positioned at the top of the Sony HDV Series.
Inheriting the design concept of the market-acclaimed DSR-1500A, the HVR-1500 offers the same convenient features that professional users demand, such as quick mechanical response, multi-format DV playback, and a rich set of professional video/audio interfaces ranging from analog to digital SDI and AES/EBU. The HVR-1500 also offers HD-SDI output and RS-422A control capabilities, bridging HDV source footage and assets with high-end HD formats and HD editing equipment.
In addition, with the optional HVBK-1520 board installed, the HVR-1500 has a range of conversion capabilities that allow DV recordings to be up-converted to 1080i or 720P signals, and 1080i HDV recordings to be cross-converted to 720P signals. This allows operators to integrate DV and HDV source footage and assets into the same HD editing system, and gives them the flexibility to choose between either a 1080i or a 720P system.
The HVR-1500 can also be used as a standard definition DVCAMTM recorder, in which case the same editing features as the DSR-1500A are offered.
The HVR-1500 is certainly the HDV recorder of choice for environments where robustness and functionality are prime concerns.

HDV FORMAT
HDV 1080i Specification
The HDV 1080i specification*2 for the HDV format features 1,080 effective scanning lines (interlace scanning system) and 1,440 horizontal pixels. It adopts the MPEG-2 compression format (MP@ H-14 for video), which uses 8-bit digital component recording with a sampling rate of 4:2:0. MPEG-1 Audio Layer II is used as the audio compression format, allowing for two-channel recording with a sampling frequency of 48 kHz/16-bit. The HDV 1080i specification provides the high 
picture quality required for HDTV program
production.
Track Pattern of the
HDV 1080i
Specification
Compatible with Existing and New
DV Videocassette Tapes
As a member of the proven DV family of formats, the HDV format was developed from the outset to be compatible with all grades of DV videocassette tape. This allows operators to use high-grade DV videocassette tapes for applications where high robustness is critical, or consumer-grade videocassette tapes for more economical operations. For heavy-duty applications, the DigitalMasterTM high-grade cassette
tape has been developed. This tape is compatible with the HDV, DVCAM, and DV formats.
*2 The HDV format also defines the HDV 720p specification, which features 720 effective scanning lines (progressive scanning system) and 1,280 horizontal pixels.
VERSATILE RECORDING & PLAYBACK
Switchable Recording
-HDV 1080i/DVCAM/DV and 60i/50i
The HVR-1500 can be switched between HDV 1080i*1, DVCAM, and DV (SP) *3 recording modes, providing full flexibility to record in either standard definition or high definition depending on your production needs. In addition, it can be switched between 60i and 50i systems, eliminating the need for two separate VTRs, one for each standard.
*1 In HDV mode, editing capabilities are not available.
*3 The HVR-1500 supports DV (SP) mode only; DV (LP) mode is not available. Assemble or insert editing is not supported in DV (SP) mode.
Playback Compatibility with DV (25 Mb/s) Family Formats
For operational versatility, the HVR-1500 is designed to play back DV (25 Mb/s) family format recorded tapes without a mechanical adaptor and without having to switch playback modes on the menu. DVCPROTM 25 recorded tapes (M-size cassettes) can also be played back.
Long Recording Time
The HDV format adopts the same track pitch and tape speed as the DV format, thus offering the same recording time – a maximum of 276 minutes when recording on a PHDV-276DM DigitalMaster standard cassette tape and 63 minutes when recording on a PHDVM-63DM DigitalMaster mini cassette tape. The DVCAM format adopts a wider track pitch than the HDV/DV format (15 µm compared to 10 µm), and offers a maximum recording time of 184 minutes on a PDV-184N standard cassette tape and 40 minutes on a PDVM-40N mini cassette tape.
Up-conversion Capability
With the optional HVBK-1520 Format Converter Board installed, the HVR-1500 has an up-conversion capability that allows DV recordings and SD signals*4 fed to the HVR-1500 to be converted to 1080i or 720P signals and then output*5 from the HD-SDI interface. This allows DV recordings to be integrated into existing HD editing systems that support the 1080i or 720P format. When up-converting the DV recording, the aspect ratio displayed can be converted from 4:3 to 16:9. Display modes can be selected from Squeeze, Edge Crop, or Letterbox.
*4 DV signals fed to the HVR-1500’s i.LINK interface cannot be up-converted and output from the HD-SDI interface.
*5 There may be a delay of one frame in outputting up-converted signals from the HD-SDI interface.
Cross-conversion Capability
With the optional HVBK-1520 Format Converter Board installed, the HVR-1500 has a cross-conversion capability that allows 1080i recordings to be converted to 720P signals, as well as 720/30P (29.97 frames/s) recordings to be converted to 1080/60i (59.94 fields/s) signals. These signals are output*6 from the HD-SDI interface. This allows source footage and assets in different HDV formats to be integrated into the same HD editing system.
*6
Down-conversion Capability
The HVR-1500 has a built-in down-conversion capability that allows 1080i recordings to be output as 480i and 576i signals from the i.LINK and SD-SDI interfaces. These signals can also be output from the analog component, composite, or S-Video connectors. This allows 1080i recordings to be edited using nonlinear editing systems running DV editing software or to be viewed on an SD monitor. When down-converting the 1080i recording, the aspect ratio displayed can be converted from 16:9 to 4:3. Display modes can be selected from Squeeze or Edge crop.
