Nice feature for a semi-automated threading of the tape :-) Works much better on this model rather than on the usual BVH-3000 because of the lesser thickness of the tape.
@@hdvs Wow! That's a huge collection! Are you planning to rip them somehow and put them on RUclips? I think the best version of HDVS is from HDD-1000 because it's fully digital. I've talked to someone who knows a lot about this stuff and he told me that most probably the source of the famous "Goodnight Tokyo" video (ruclips.net/video/KJQsGpCDX54/видео.html) is an HDD-1000 tape and therefore the quality is amazing. So that would be great to watch those tapes. Regards
Retro-Reels I thought it was the BVH-3000, but I think the BVH-3100 is better than the BVH-3000. I'm not sure. Oh, and by the way, this recorder did use compression, but despite being digital it used no fancy compression beyond basic, initial 22:11:11 digital sampling ratio, 8-bit samples, and then further compression down to 45 MHz of digitally-encoded, bandwidth from 180 MHz uncompressed feed directly from the HDCU that the camera was attached to.
1 million Yen? That's a very cheap price if we consider how much they cost back in the Nineties, at least here in Italy. BTW, as far as I know, the video head-drum is unavailable.
I am looking for a machine like this as well as a Sony BVH-3000/3100 in Ontario Canada if anyone has one for sale or can donate to my archive in Ontario Canada I would greatly appreciate it!
Introduced in 1997, HDCAM was 10 bits quanitzation (analog-to-digital conversion), but with 8-bit samples actually laid on the tape itself in a 3:1:1 digital sampling format; it also used slight luminance prefiltering, or supersampling, to squeeze a 1920x1080 (16:9) image into a 1440x1080 (4:3) one. The luminance (Y) spatial digital sampling was 1440x1080; the two chrominance-difference components (Cb, Cr), were 480x1080 each. The frame rate was 30 fps, which means the luminance bandwidth was 46.656 MHz, and the two chrominance-difference components were each 15.552 MHz, which translates to 77.76 MHz of total bandwidth after luminance prefiltering and chrominance decimation (subsampling). This value multiplied by 8 bits per sample gives 620.8 Mbps of bandwidth, which is then further compressed via DCT (direct cosine transform) compression with a ratio of approximately 4.4:1; the final bandwidth of the signal that gets to the 0.5" HDCAM tape format is 140 Mbps. Overall compression ratio from uncompressed 1920x1080 captured at 30 fps with 8 bits per sample is 10.56:1, when you include the precompression ratio of 2.4:1 (luminance prefiltering and chrominance subsampling), multiplied by the additional compression ratio of 4.4:1 for DCT. Introduced in 1988, the HDD-1000 format utilized 9-bit quantization with a 22:11:11 sampling ratio with 9-bit samples actually being laid to the tape. Bandwidth for the luminance channel was 30 MHz and the bandwidth for each of the two chrominance-difference components was 10 MHz each. Assuming a 1035-active-line acquisition format, and a fixed vertical resolution, in a 16:9 aspect ratio, and a frame rate of 30 fps, the luminance resolution would be approximately 966x1035, and the two chrominance channels' resolution would be approximately 322x1035. The overall precompression ratio would be 1.5:1, thanks to the initial 22:11:11 digital sampling ratio, with further bandwidth reductions further increasing the compression ratio to approximately 2.3:1, for a total overall compression ratio of approximately 3.4:1. 50 MHz of total digitally sampled bandwidth multiplied by 9 bits per sample equates to 450 Mbps of total bit-rate that is encoded directly onto the 1" tape, which ran at a speed of 88 cm/sec during recording and playback. The reels could hold up to 60 minutes of program material and each one cost $2,000 new; the entire recorder itself cost $600,000 new way back in '88! It still produces video with a bit rate that is over ten times higher than the maximum theoretical bit rate of a Blu-Ray disc is, which is 40 Mbps--and even that is higher by far than streaming services that offer 1920x1080 resolution content or higher resolution content. I hope you might be interested in this information.
I actually have revised my information regarding this digital VTR--it has a digital resolution of 1920x1035/60i and encodes data in a 22:11:11 sampling structure (the true notation used to describe HD digital component sampling). The quantization is 8 bits, and the sampling rate for the effective active picture area (1920x1035 for Y, 960x1035 for B-Y/R-Y) is Y: 59.616 MHz, B-Y: 29.808, R-Y: 29.808 MHz, total: 119.232 MHz. The final bandwidth is 953.856 Mbps (which is slightly higher than the stated 944 Mbps of effective bandwidth for this digital VTR) for the effective video data and the overall data recorded to the tape is 1.2 Gbps to account for Reed-Solomon ECC (error correcting code). There is also 8 digital channels of audio encoded with 20-bit quantization and a sampling rate of 48 kHz (total bandwidth for all eight channels is 7.68 Mbps, or 960 kbps per channel), plus a single FM analog audio channel and an additional analog audio channel for the cue track.
I never knew that there was a HD platform using 1" tape WOW!!! I must acquire one
Sony HDD-1000: *has tape-threading abilities*
Me: That could've made it possible to play reel to reel audio tapes in the car.
Beautiful machine!!!
Hi!
May I ask you which tapes do you have?
Regards
I’ve about 100 tapes, mainly concerts, documentaries and advertising. Didn’t make a detailed list though.

No compression ! 1035 line. Transport is based on the BVH-3100

Stunning!
日本語で失礼します。カッケーーーマジで。
I want one . I can plug it into my tv with an HDMI lead or SCART lead .
これにテープかけるのめっちゃ緊張した。ヘッド欠けたらヘッド交換100万円‼️だからなー

Where'd you got this and the Sony HDF-500 from?
Teaxs Instruments DLP division, 23 years ago.
@@hdvs I see.

Hey dude, how does the quality compare to HDCAM tapes?
