Toshiba SD-9200

Commentary

A flagship DVD video / audio player that supports both DVD video and DVD audio.

Video part

The video DAC uses a high-performance 10-bit / 54 MHz video D/A converter.
By drastically increasing the processing speed of the video DAC from 10-bit / 27-MHz to 54 MHz, it is possible to perform high-speed arithmetic processing with more latitude. In addition, signal degradation is minimized because 8-bit data is converted to 10-bit data before processing.
In addition, color reproducibility has been greatly improved by 4 : 4 : 4 video signal processing, which upsampled the color-difference signal band.

Equipped with an independently developed high-resolution progressive video circuit capable of obtaining a horizontal resolution of 540 lines even in the progressive video system.
Conventional progressive signal conversion circuits (10-bit / 27-MHz) have caused information loss and noise contamination in video signals due to their structure. However, with the high-speed processing capability of 10-bit / 54 MHz, this circuit realizes over-sampling processing of progressive signals and enables digital filtering of progressive signals, which previously relied only on analog filters. This minimizes noise levels and realizes video signal conversion without information loss.

It uses a real theater mode progressive conversion circuit that enables film-like smooth image reproduction.
Conventional circuits normally perform 3-2 pull-down processing (telecine conversion) when playing back video software for DVDs recorded at 24 frames per second, resulting in overlapping fields and jagged outlines of moving subjects.
In the Real Theater Mode Progressive Conversion Circuit, 24-frame video is converted as it is into 60-frame video at double speed, so that no field overlap due to telecine conversion occurs and natural and smooth video reproduction is realized.

The video encoder with built-in super sub alias filter, which enables horizontal resolution of 540 lines, is further upgraded.
In the circuit installed this time, the calculation capability is doubled by changing the digital filter from 27 MHz operation to 54 MHz operation, and by realizing 4 times over sampling, higher quality reproduction is possible.

It is equipped with a 3-dimensional DNR circuit, and by using a frame memory, noise mixed at mastering level and noise of original film are removed from the video signal with high precision. This realizes a transparent image with less noise.

The output signal of the video encoder is processed by a wide-band uniform response filter with a flat group delay characteristic up to the ultra-high frequency band of 15 mhz to remove the clock component with high precision.
In addition, by operating ± 2 power supplies, a high-speed, wide-band OP amplifier with a slew rate of 500 V / μ sec and video bandwidth of 100 MHz enables a direct coupling configuration and realizes a high-quality video signal with minimal APL fluctuation.

Each of the interlaced and progressive methods provides detailed image quality control.

D2 video output terminal and component video output terminal are mounted.

It is equipped with a bit rate indicator display function which can confirm the change of transfer data volume on the screen.
When video data is compressed and recorded on a DVD using MPEG2, a variable transfer rate technology is used to allocate the amount of data according to changes in the image state. With this function, when a DVD is played back, a rough indication of the amount of data transferred for each image can be displayed on the screen using numbers and a level bar.

Equipped with high-quality letterbox conversion circuit.
When you play a 16 : 9 DVD video on a 4 : 3 TV, a letterbox conversion is performed to convert the original video, which consists of 480 effective lines, to 360 lines (360 lines) without the Kuroobi portion.
This conversion circuit uses a 4-tap vertical filter developed in-house. It calculates four original scanning lines at high speed and generates new lines with uniform characteristics. As a result, higher quality images can be reproduced than the conventional letterbox image quality.

It is equipped with an optimum servo that realizes stable playback by adapting to the disc condition.

Auto Pause Mode automatically controls the still image display according to the state.

The S-Video output is mounted.

Audio part

To fully support high-spec DVD audio, the D/A converter for all channels uses a high-performance audio DAC developed jointly with Analog Devices Inc. of the United States. This is an improvement over the conventional Advanced Multi-bit Delta Sigma DAC.
A multi-bit system with high jitter tolerance and low noise is combined with a 1-bit system with excellent linearity and no 0 cross distortion. The increase of differential linearity error is reduced by an advanced error averaging circuit between elements.
As a result, we have achieved high performance with a total harmonic distortion rate of less than 0.0008% and a dynamic range of more than 116 dB.


The Mega-Resolution Parallel DAC proprietary technology that enables high-quality and stable voice output.
This circuit inherits the adaptive multi-port parallel DAC method adopted in the SD-V620. It is equipped with three high-performance Neo Multi-bit Delta Sigma D/A converters and the operation mode can be changed according to the content of the source to be reproduced.
In particular, in 2-channel playback, three DACs per channel are connected in parallel to average the signal, which effectively reduces noise without affecting the audio signal and greatly improves the performance of the audio circuit.

High-quality materials are used for various parts that affect hearing sensitivity.
A specially designed high-quality electrolytic capacitor is used for the analog power supply of the audio circuit. A newly developed non-polar capacitor is used for the coupling circuit, and an audio electrolytic capacitor with excellent low-impedance characteristics is used for the digital circuit.
In addition, a foil-type polypropylene film capacitor and a high-precision metal-coated S surface mounted resistor are used for the low-pass filter of the signal system. Together with a double-sided printed circuit board made of glass-epoxy material, high-density mounting is carried out and the signal path is shortened.

In order to further take advantage of the characteristics of coaxial digital output, which is more advantageous than optical output in terms of jitter characteristics, we have adopted a high-quality output circuit that uses a balanced drive type buffer amplifier instead of a conventional single-end buffer amplifier.
In addition, the combination of a newly developed toroidal pulse transformer with good waveform response and broadband characteristics makes it possible to output high-quality digital signals resistant to electrical noise.

The power supply section employs a dual-transformer switching power supply with dedicated transformers for each of the mechanical system, main signal processing system and AV circuit system. By implementing high-speed SW operation at 75 kHz or higher and incorporating a control circuit to reduce ringing of the SW waveform, it realizes a sense of power and silence not found in conventional SW regulators.

In order to suppress the deterioration of sound quality caused by the vibration of the housing structure, we are pursuing improved vibration control and increased weight.
The SD 9200 has a chassis made of 1.2 mm thick copper-plated steel sheet, a low-center anchor base attached to a high-density resin material with 2 mm thick vibration-damping steel sheet, and a low-center anchor base placed at the bottom. In addition, hybrid top b-channel and reinforced anodized hard insulator are used at the legs for superior exciting effect due to bonding of dissimilar metals.
In addition, a solid aluminum pull-out material is used for the front panel to create a high-quality appearance.

It has a built-in Dolby Digital 5.1 ch decoder and DTS decoder.

With the built-in zoom function, you can enlarge the center of the screen up to approximately 3.5 times by pressing the zoom button on the remote control during playback. You can also reduce the screen so that the edge of the screen is not chipped, and you can move the part you want by the remote control up, down, left or right to zoom in on still images.

Equipped with an auto power off function, the power is automatically turned off when playback stops or screen saver operation continues for approximately 20 minutes.

Equipped with a screen saver function, when playing DVD video, the screen saver automatically activates when the still image lasts for a long time depending on the pose state to prevent the screen from burning.

Wireless remote control is included.
