Implementation of protocols in the Audio and Video over IP industry: Dante and NDI leading the way

RH Consulting (RHC) is an independent agency specialized in audio and networking consulting. Recientemente han realizado un studio sobre la implantación de los protocolo de audio y de vídeo en las nuevas instalaciones sobre IP. Su estudio número 11 ha arrojado luz sobre algunas de las tendencias que se desarrollan en la industria.

It covers all the major protocols including Dante, RAVENNA, AES67, AVB, Milan and others. Following the addition of video and control protocols in last year’s report, RHC have added IPMX and NDI and will further broaden the scope in the future.

The statistics show that the number of networked AV products on the market continues to grow, with the total number of products being shipped being charted at 5,219, from 552 different brands. This increase of over 1,000 from last year’s report seems to indicate that the industry is successfully rebounding from a rough spell of years caused by the pandemic.

Dante once again cements its dominance in the Audio over IP (AoIP) sector, adding more products to the market than all other protocols combined and RAVENNA continue their steady progress in second place, as the protocol of choice in the broadcast industry.

With regard to video, analysts point out that the adoption of video over IP has been much slower than that of audio. The main reason is bandwidth limitations, which in the case of video only allow some feeds to pass and not all the necessary ones. In the words of Roland Hemming, from RHC, on the Video over IP data: “We observed that many of the products are simply video encoders/decoders, which reminds us of the early days of AoIP.”

“The Video networking market is still in its infancy when compared to AoIP, but now that we have collated two years of data, we can begin to draw a line. NDI are currently leading the charge in this category in terms of overall manufacture and distribution and are also making the most concerted effort to embed this technology inside their products. We’re excited to see how this develops in the future as technologies improve.”
