GlossaryDigital Broadcasts and D-VHS

Great changes in the entertainment and media industries are transforming the way we use VHS, and digital broadcasting is a good example of what the future holds. Digital broadcasting now allows more efficient use of the limited broadcast spectrum besides delivering high- definition video, outstanding sound quality, multiple channels, and multiple features.

Meanwhile, VHS has evolved with the advances in broadcasting in response to the need for continued use of existing VHS resources and the trend toward digital broadcasts.

Digital broadcasting is not limited to transmissions of audio and video content. A variety of other data can be sent as well. As the means to record all of these digital signals while supporting playback of the extensive VHS library of analog tapes, D-VHS was developed.

This VCR is equipped with an MPEG-2 encoder and decoder (codec) for digital recording and playback of analog signals.

D-VHS is the key to a smooth transition from analog to digital formats. This next-generation home video technology lets us continue to enjoy home video entertainment as popularized in the last century well into the next.

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.

Set “OPTICAL OUT” to “Dolby D” ( pg. 55).

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.
