About recording time

The recording time of a typical VCR (Video Cassette Recorder) is determined by the length of a video tape and recording speed (SP, LP, etc.). Video tapes with various recording times are available in the market. On the other hand, the recording time of a DVD-RAM/ R/RW depends on the bit rate (Mbps: amount of data transmitted per second), which can be varied in MPEG2 (Moving Picture Experts Group2) compression technology.

As an example, when you pour water into a bucket from a faucet, the faster the water flows, the sooner the bucket is filled with water. On the other hand, the slower the water flows, the more slowly the bucket is filled. The DVD-RAM/R/RW is, so to speak, such a bucket, and the degree you turn the faucet is bit rate, the time required to fill the bucket with water is the recording time available for a disc. The higher you set the bit rate (making much more water flow), the sooner a disc is filled. Consequently, the recording time becomes shorter. The lower you set the bit rate, the longer time it takes to fill a disc.

About picture quality (XP, SP, MP, LP, EP)

The higher you set the bite rate, the more the volume of information for the picture. The lower the bit rate, the less the volume of picture information.

However a high bit rate does not always mean that the picture quality is high. The difference between the 1.4 Mbps and 9.2 Mbps is obvious, but when comparing similar bit rates, the difference may be insignificant. Generally when you set the bit rate low for longer recording time, the data volume shortage will result in a lack of detail information. As a result, the picture quality is decreased (more noticeable with dynamically moving images). For example, square noises (block noise) may occur in a scene with fast action or a scene with light and shadows, such as a water surface.

This recorder has 6 settings. (e.g. “SP” records about 2 hours and “LP” about 4 hours onto a blank 4.7 GB

DVD-RAM disc. page 125) It is recommended to consider the “SP” mode as a standard mode and use the lower mode when you want to record for long time regardless of the picture quality.

If you want to record for within 2 hours select the “AT” mode.

On a blank 4.7 GB DVD-RAM disc, the “AT” mode automatically sets the appropriate bit rate corresponded to the recording time from about 1 hour to up to 2 hours so that you can achieve the best picture quality. If a part of a DVD-RAM disc has already been recorded, the “AT” mode sets the bit rate suitable for the remaining space on the disc. (The picture quality is determined referring the remaining space just before recording. When the remaining space is scarce in the disc, the picture quality may decrease from what you set beforehand or the recording may stop halfway.) “AT” mode is available also on DVD-R/RW recordings.

When you want to record a music program or animation with high picture quality, it is recommended that you select the “XP” mode. If you select more than 6 Mbps, you can usually record with considerably higher picture quality. However the higher you set the bit rate, the shorter the recording time.

D /M1

Sound recording format onto DVD-RAM discs. When recording, sounds are converted into digital signals and compressed. In playback, they are extracted to the

original sound. D /M1 is applied the digital recording technology for consumer products of Dolby Laboratories. Dolby Digital 192 kbps is set for

D /M1.

D-R4SU specifications

Toshiba has established a strong presence in the world of energy-efficient solutions with its latest series of air conditioning systems, specifically the D-KR4SU, D-R4SC, and D-R4SU models. These systems are designed to meet the diverse needs of both residential and commercial spaces, providing comfort while also promoting energy conservation.

The D-KR4SU is engineered with advanced inverter technology that maximizes energy efficiency and minimizes electricity consumption. This model utilizes a variable-speed compressor that adjusts the cooling or heating output based on the current demand, ensuring optimal performance without wasting power. The sleek and modern design makes it a great fit for contemporary interiors, while its whisper-quiet operation ensures that occupants enjoy a peaceful environment.

Focusing on the D-R4SC, this split-type air conditioner is specifically designed for quick and efficient installation. It provides reliable cooling or heating, enhancing indoor comfort with its effective airflow distribution. One of the standout features of the D-R4SC is its smart control options, which allow users to manage settings remotely via a dedicated app. This feature exemplifies Toshiba’s commitment to integrating technology into their products, creating an intuitive user experience.

The D-R4SU model takes energy efficiency a step further by employing R32 refrigerant, known for its low environmental impact. This refrigerant not only reduces global warming potential but also enhances the overall efficiency of the unit. Furthermore, the D-R4SU includes advanced air filtration systems that ensure clean and healthy air quality, removing allergens and particulates from the environment.

All three models come equipped with features such as programmable timers, various cooling and heating modes, and energy-saving settings that help users optimize their energy consumption while maintaining comfort. The easy-to-use remote control and user-friendly interface allow seamless operation and flexibility for managing indoor climates.

In conclusion, Toshiba’s D-KR4SU, D-R4SC, and D-R4SU models represent a fusion of energy efficiency, advanced technology, and user-centered design. With their ability to provide optimal comfort while reducing energy usage, these air conditioning systems are ideal choices for those looking to enhance their indoor environments sustainably and efficiently.
