Upon that introduction, these HDV systems gained a rapid and wide acceptance due to their high picture quality, outstanding performance, and cost- effectiveness. Today, in response to the demands for greater levels of operability such as longer recording time and time-code-recording capabilities, Sony introduces its latest HDV recorders – the HVR-M25 and HVR-M15. The HVR-M25 and HVR-M15 enable users to record and play back video in a choice of formats – HDV 1080i, DVCAM™, and DV. They also feature a down-conversion capability for 1080i recording, which provides the flexibility to record in either standard definition (SD) or high definition (HD) depending on your production needs. One of the most powerful features of these VTRs is their compatibility with standard cassettes in addition to mini cassettes, which provides extended recording time of up to 276 minutes. In addition, these VTRs provide a convenient function to copy not just the video and audio of an original tape via an i.LINKTM*1 connection, but also the time code. Both models are optimized for use with nonlinear editing systems thanks to their highly compact size and easy operations. However, the HVR-M25 provides additional powerful features such as a built-in 2.7-inch*2 type, 16:9 LCD monitor and an HDMI (High Definition Multimedia Interface) output for more demanding production environments. The HVR-M25 and HVR-M15 offer a highly powerful, yet cost-effective tool for nonlinear editing systems that will serve both today’s production needs, as well as those of tomorrow. HDV FORMAT HDV 1080i Specification The HDV 1080i specification*3 of 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 Track Pattern of the HDV 1080i Specification provides high picture quality that can be used for HDTV program production. Compatible with Existing and New DV Videocassette Tape As a member of the proven DV family of formats, the HDV format has, from the outset, been developed for compatibility 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. HVR-M25 & HVR-M15 COMMON FEATURES Switchable Recording and Playback – HDV 1080i/DVCAM/DV SP and 60i/50i The HVR-M25/M15 can switch between HDV 1080i, DVCAM, and DV*4 recording, 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 modes (NTSC and PAL), which allows for flexible production operations, without the need for two separate VTRs of each standard. Dual-size Cassette Mechanism The HVR-M25/M15 has a dual-size cassette mechanism that accepts both mini- and standard-sized DigitalMaster, DVCAM, and DV cassette tapes – without using any special adaptor. This feature allows the six different types of cassette tape to be used without the cumbersome process associated with additional mechanical hardware. 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 DigitalMaster standard cassette tape and a maximum of 63 minutes when recording on a DigitalMaster mini cassette tape. *1 i.LINK is a trademark of Sony Corporation used only to designate that a product contains an IEEE 1394 connector.

HVR-M25 & HVR-M15 COMMON FEATURES Down-conversion Playback Capabilities The HVR-M25/M15 can convert material from 1080i down to 480i and 576i, and output these video signals through its i.LINK interface. In addition, these signals can also be output via the VTR’s HDMI (on the HVR-M25), analog component, S-video, or composite connector. This allows users to edit recorded material with a compatible non...
