D-VHS

By utilizing the characteristic of the tape media, video and audio data compressed using MPEG2 method can be recorded at high-speed rate and in high volume.

Bit stream recording*1 method is employed to record inputted MPEG2-TS signals (signals with additional information such as program assignment for service access other than MPEG2 video and audio data) directly. This unit is equipped with MPEG2 encoder/decoder*2 that enables digital recording and playback for analog signal (this unit supports only NTSC signal).

In addition, a vast amount of VHS analog recording images can be playbacked. This is D-VHS.

This unit has the feature to record and playback S-VHS and S-VHS ET as well.

*1 Bit Stream Recording

Bit stream recording is a method to record the MPEG-TS signals compressed by MPEG2 on the tape directly and output the same type of signals.

This unit enables recording and playback of high definition MPEG2-TS signals at a high speed HS mode of 28.2 Mbps.

*2 MPEG2 Decoder

This unit is also equipped with MPEG2 decoder to decode the MPEG-TS signals and output analog Y/Pb/Pr during playback.

When decoding MPEG-TS signals recorded at 720/30P, the signal will be converted to 720/60P that is generally used.

Linear PCM Audio

Conventional D-VHS recording uses MPEG-1 Layer 2 compression to record analog audio digitally.

For recording without compression, this VCR also features PCM recording (pulse code modulation: 48 kHz, 16-bit, 1536 kbps).

Used with high-resolution HS/STD mode, it offers outstanding high-fidelity recording and playback. (Recording from audio input alone is not supported.)

Dolby Digital

A form of digital audio coding developed by Dolby Laboratories to deliver surround sound with 5.1 channels (front left and right, center, rear left and right, and a channel for LFE (low-frequency effects).

When you play back a digital tape encoded in Dolby Digital format, the Dolby Digital bistream is sent from the DIGITAL OUT OPTICAL connector.

i.LINK

i.LINK is a digital serial interface that allows devices equipped with an i.LINK connector to exchange digital video signals, digital audio signals, and device control signals bi-directionally over a single cable.

i.Link refers to the IEEE1394-1995 industry specification and extensions thereof. The logo is used for products compliant with the i.Link standard.

MPEG2

Abbreviation for Moving Picture Experts Group, Phase 2. Unlike previous compression methods, MPEG-2 uses an extremely efficient compression method that supports high-definition video. Based on the principle that much video data remains unchanged from one frame to the next, predictive coding is performed to eliminate redundant data.

Specifically, compression is applied between frames (based on the correlation of frame data) and within frames (based on DCT, or discrete cosine transform) for an extremely efficient compression technique.
