Research on video format images and next generation audio recording formats. as of 2022/02/23.

First of all, the law on adult videos should set the standard of no mosaic on male and female genitals, which has been a concession of the National Police Agency and the Metropolitan Police Department, and set regulations on filming and broadcasting of dirty things such as excrement (tantrums, vomit, and poo are prohibited, but spit, semen, love juice, and urine discharge are allowed).

The basic format for video should be 4K, with 8K and possibly 16K in the future.

We also propose that the standard for the next generation audio format should be a hybrid of MQA and 360 Reality Audio. The advantage of this format is that it is lossless, high-resolution, supports surround sound from multi-channel speakers, and has better sound quality than existing formats. MQACD, however, has the advantage of better sound quality, even when played on older CD players.

MQA CD player or MQA UAB-DAC can be connected between the computer and the amplifier. Possibly, although I'm not sure about DVD.

Start quoting.

In fact, if you look at the MQA-CDs that are currently on the market, they are made from three different masters. For example, the MQA-CD of Yoshitaka Minami's "Dear My Generation," which was the first new Japanese music recording to be released on MQA-CD, is an 88kHz 24bit PCM master. For example, the MQA-CD of Yoshitaka Minami's "Dear My Generation," which was the first Japanese music album to be released in MQA-CD format, was mastered at 88kHz 24bit PCM, and the world's first MQA-CD, "A. Piazzolla by Strings and Oboe," released by the Japanese Unamas label, was mastered at 176kHz 24bit.

End of quote.

The standard for MQA Studio seems to be 352.8kHz/24bit.

However, considering that Blu-Ray will be obsolete in the future, and there is a possibility that the recording capacity will be limited, it may be fine if it is not supported. However, for the future mainstream music distribution such as Youtube, UNEXT, Netflix, and Amazon MusicHD, the hybrid of MQA and 360 Reality Audio, MQA Studio's 352.8kHz/24bit or

There is room to consider whether MQA Studio Ver2 with 384,000Hz/32bit (PCM) should be the standard.

I would like to see a law to promote the use of hardware with the latest formats mentioned above.

There are some speakers that have USB-DAC, MQA and digital amplifier built-in.

USB-DAC & TV should be equipped with MQA Studio Ver2 (MQA compatible) function, USB-DAC output function, and either S/PDIF optical digital output or optical coaxial output as a standard specification.

MQA Studio Ver2 (MQA compatible) is not only for music players, video players, music distribution and video-on-demand distribution, but also for TV, radio, landline phones, cell phones, smart phones, wireless devices, in cars, locomotives, trains, in-flight and on-board broadcasting. In addition to TVs, radios, fixed phones, mobile phones, smart phones, wireless devices, and in-vehicle, in-train, in-flight, and on-board broadcasts, it is expected that the sound quality will be improved in response to 4K and 8K broadcasts. The adoption of 4K & 8K broadcasting is expected to improve the quality of life and convenience of the people.

4K, 5K, and 8K (including 16K in the future) compatible PCs, tablets, smartphones, game machines, OS, websites, and websites should consider and give consideration to high resolution support, and consider and give consideration to HiDPI as a standard.

For PCs, the OS should be 64bit, the system memory 16GB, and the storage media should be NVMe SSD 1TB or more.

I would like to see quiet, fanless CPUs with a TDP of up to 65W as a standard specification.

I would like to see USB-C to USB-C as the standard connector for smartphones and tablets.
