Waversa Network Direct Rendering (WNDR)

The biggest problem with streaming on widely used networks using DLNA is that the standard does not consider continuous audio streaming at all; it is just a standard for packet-based data transmission allowing multitasking Ethernet switches to function seamlessly while maintaining accuracy. In this transmission method, noise is generated during the buffering process during signal transmission resulting in extremely poor sound quality. WNDR (Waversa Network Direct Rendering) is a more advanced proprietary protocol developed by Waversa Systems to solve these problems. It has been designed to minimize delays in communication and provide excellent noise immunity. In addition, the WNDR method is a dedicated protocol, so there is no need for a conversion process between protocols, thus again improving sound quality.

 

The WNDR (Waversa Network Direct Rendering) dedicated protocol is a:

 

 ● Transmission scheme optimised for continuous signal processing without buffering

 ● Protocol with strong immunity to noise

 ● Protocol without conversion process by dedicated route

 ● System capable of increasing WAP level when WNDR devices are interconnected, resulting in improved sound quality

 

WNDR is a protocol dedicated to the transfer of pure music with little and, if selected, no buffering, thus creating a special advantage whereby there is almost no noise during signal transmission, eliminating any notable distortion of sound quality.

When reading buffered data as shown in Figure 8, the process of reading and transmitting data with a renderer board occurs intermittently, which causes electrical noise. The stable transfer of continuous information without buffering will be the core technology of the future, and since media integration tends to be parallel to communication, stable clock synchronization without buffering will also be achieved. The technology to make this happen is WNDR, which is a great sound quality advantage.

 

You can tell if there is buffering by unplugging the network cable. In the case of DLNA, music plays continuously for 30 seconds or more, and in the case of ROON RAAT, music plays for several seconds. This means that buffered music data is being played. However, in the case of WNDR, the music is interrupted almost immediately when the network cable is unplugged. This is because there is no buffering.

Waversa Systems devices are the only consumer digital products in the world that operate with a proprietary music data transfer protocol. WNDR produces a synergistic effect when all devices are integrated, and combines with WAP to achieve even better sound quality. When the WCORE, WRouter, and WDAC3C are all connected by selecting WNDR in each of them, as shown in Figure 9, they each will have clear sound quality benefits; however, in addition, together they raise the overall WAP level, achieving superior sound quality in all aspects.
