Used JVC JVC Compact HDV/DV Format Video Recorder with DVCAM Playback, Cross Converter 1080i/720p/480i Output, 50Hz/60Hz Compatibility.

• The companion model to the GY-HD100, this HDV/DV spooler is designed to transfer video and audio data to a non-linear editing system. Optimized for use with a wide variety of existing systems and formats, this unit features switchable HDV and DV modes and analog outputs.
• You can also connect it to a plasma or LCD panel equipped with an HDMI connector and use it as a low-cost viewer. With its low cost and high flexibility, the BR-HD50 is ideal for any facility looking for a smooth upgrade path from standard definition to HD.
• HDV recording; As the HDV format uses the same recording track pitch as Professional DV, the BR-HD50 can record signals in either standard or high definition depending on the user's needs.
• Multi-format output/Cross-converter function; A sophisticated cross-converter function enables output not only of 720p signals, but also 1080i, 480/576p and 480/576i signals. Plus, thanks to switchable HDV and DV recording mode functionality along with DVCAM playback, you'll have no problems adding this recorder/player to your existing editing system.
• HDV international compatibility; Switch between HDV 60 Hz or 50 Hz base as required, allowing recording and playback of 720/25p and 576/50p in addition to 720/24p/30p and 480/60p. This makes it easy to work with internationally sourced material and transfer it to a non-linear system for editing and then archiving to tape. You can also record to standard DV or Mini DV tape in either HDV 60 Hz or 50 Hz base format. Cannot be used as an HDV 60 Hz/50 Hz converter. The BR-HD50U can record and play back signals in both HDV 60 Hz and 50 Hz formats.
• Standard DV/Mini DV compatible mechanism; Proven on Professional DV VCRs, this mechanism provides not only improved running stability, but also accommodates both Standard DV and Mini DV format cassettes without any adapter. DVCAM playback capability (SD); DVCAM recordings can be played back directly on the BR-HD50. This makes it easy to use DVCAM recordings as source material for editing.
• Auto error correction system JVC has developed an auto error correction system that operates on a frame-by-frame basis to ensure accurate error compensation during playback. After optimally calibrating the playback RF wave form with a pre-filter circuit, the VCO (voltage control oscillator) control voltage is changed so that the data reading clock phase is shifted to the position where the error rate is lowest. The result is accurate, consistent suppression of block noise and reliable, professional-standard performance at all times.

Sweeper heads During recording and playback, to reduce the block noise which is caused by dust adhering to the heads, our HDV/DV camcorder and recorders incorporate an advanced drum assembly with specially designed "sweeper" heads. These dummy heads sweep off any magnetic material dropped by the tape or any dust that may have entered from outside the unit.
