えい ほうShare
Aestiquo, as a specialized brand for home entertainment devices, offers products that meet users' needs. For those who wish to enjoy DVD content on their smartphones, we will guide you through legal and safe methods. We will explain the Copyright Act and technical restrictions in detail, and introduce the correct operating procedures using Aestiquo's PD141/PD156 models.
Explanation of Article 30 of the Japanese Copyright Act
While protecting the rights of copyright holders, the Japanese Copyright Act permits private use within certain limits. Among these, Article 30, as a "special provision for private sound and visual recording," stipulates that individuals may record or video copyrighted works of others for their own private use. However, this comes with strict conditions.

Furthermore, Article 30-2 of the Copyright Act prohibits recording or videoing copyrighted works protected by "technical protection measures" by circumventing those measures. Copy protection technologies such as CPRM (Content Protection for Recordable Media) installed on DVDs fall under these technical protection measures. Therefore, copying commercially available DVDs by circumventing CPRM is a violation of the Copyright Act.

Legal Operating Procedures
1. Preparation for Recording
1 Prepare and format a USB flash drive or SD card (up to 32GB). Power on the PD141/PD156 and connect it to a TV with an HDMI cable.
2. DVD Set and Recording Settings/Start
2 Insert a DVD into the device and press the "Record" button on the remote control. On the recording settings screen, select the recording quality (720x576 or lower) and recording destination (USB/SD card). After setting, start DVD playback with the "Play" button and begin recording with the "Start Recording" button. Press the "Stop Recording" button to end recording.
3. Transfer to Smartphone
3 Once recording is complete, remove the USB flash drive or SD card from the PD141/PD156 and connect it to your smartphone. By using an OTG cable, many Android smartphones can directly recognize a USB flash drive. iOS users should use a compatible adapter.
4. Preparing a Playback App
4 You need to have an app installed on your smartphone that can play MPEG4/AVI format videos. If codec issues occur, we recommend using a universal player such as VLC media player.
Warning of Violation Risks
⚠️Risk of Copyright Infringement: Private recording under Article 30 of the Copyright Act is limited to personal private use. Distributing recorded content to others or publishing it on social media, etc., is an act of copyright infringement.
⚠️Circumvention of Technical Protection Measures: Using software or hardware to circumvent technical protection measures such as CPRM is prohibited by Article 120-2 of the Copyright Act.
⚠️Use of Illegal Copying Software: While various software exists online to assist in copying DVDs, many of them have functions to circumvent technical protection measures. Using such software is illegal and should be strictly avoided.
