BenQ WDC20 White Paper - Page 7

The InstaShowTM Series is a strong security system To solve the threats of wireless networks and enhance network security, BenQ gets rid of network threats through system modularization and thus has designed a wireless A/V streaming conference presentation system without the need to install software, the InstaShowTM Series. The power consumption module system The Button's power system in the InstaShowTM Series uses DC 5.0V converted to DC 3.3V as the main power voltage for the Button.According to the law of conservation of energy, electric current can be raised through lowering the voltage, allowing small power to support operations of the Button.The power specs of the Host in InstaShowTM S is DC 5.0V converted to DC 3.3V, the power specs of the host in InstaShowTM S is DC 12.0V converted to DC 5.0V and 3.3V.The power consumption module system in the InstaShowTM Series has passed 20,000 hour MTBF power certification, and the Host complies with (EC) No. 107/2009, (EU) No. 801/2013 and (EU) 2016/2282 regulations separately, providing the user with a trustworthy, stable and safe electrical design. The A/V module system The interfaces of the A/V source in the InstaShowTM Series are HDMI and USB Type-C. USB Type-C transmits DisplayPort A/V signals through supporting DisplayPort alternate mode. Because HDMI and DisplayPort are fully digitalized A/V signals, they support uncompressed audio and video signals and both are protected by HDCP regulations.The Host and Button in the InstaShowTM Series both comply with HDMI 1.4b (DPCP 1.2) and HDCP 1.4b(DP 1.2) certification standards.As long as the A/V source and A/V output device (sink) support HDMI 1.4b (DP 1.2) / HDCP 1.4b(DPCP 1.2), the source and sink can both be compatible with the InstaShowTM Series.The certifications the InstaShowTM Series have are ATCTW-16031 (Host), and ATCTW-16032 (Button). The A/V encoding/decoding module system Since HDMI and DisplayPort transmits uncompressed audio and video signals and the data amount from the uncompressed 1080P@60Hz audio and video signals is very tremendous, if the tremendous amount of streaming data hasn't gone through compression and transmitted wirelessly, the streaming data will take up extremely large amount of the bandwidth.To solve the problem of not enough wireless bandwidth, the InstaShowTM Series introduces unique A/V encoding and decoding methods to compress the bandwidth used by the tremendous A/V signals down to 40Mbps (InstaShowTM)/20Mbps (InstaShowTM S) to provide the user with stable, smooth wireless A/V playing experience. Furthermore, in order to dedicate to balanced distribution of A/V quality and bandwidth used by the transmission, BenQ moreover introduces a dynamic encoding technology.Through this technology the compression ratio of A/V data can be adjusted dynamically to cope with the wireless bandwidth in the environment and make adjustments all the time. 7 January 2020
