About the Web Services Platform
The Vidyo Web Services Platform offers access to its state of the art, internet-based video conferencing technology.
The Vidyo Web Services Package consists of the Web Services API, sample code, and this Web Services API User Guide for users who wish to develop their own front-end portals or video endpoint applications.
This User Guide describes how to use the Web Services API for developing custom applications for user and admin management in order to facilitate everything required to initiate and manage a conference call.
The System in Brief
Vidyo’s end-to-end enterprise solution leverages the ground breaking possibilities offered by the H.264 SVC standard combined with Vidyo’s patent pending VidyoTechnology to produce a rate-matched, personal layout, HD VidyoConference experience on any IP based general purpose network—even the Internet. The diagram below illustrates a typical deployment.
This chapter provides a high level description for the major VidyoConferencing components:
Vidyo Solution Benefits Summary vs. H.264 AVC
This table summarizes the main advantages of Vidyo’s Telepresence solution.
|Vidyo Quality||VidyoTechnology displays excellent video quality in respect to bandwidth availability, CPU usage and peripheral devices. Since no MCU is needed, VidyoTechnology provides a better image quality under identical conditions. With Legacy H.264 AVC products the MCU adds additional encode-compose-decode function which reduces overall experience, and adds significant delays.|
|Vidyo Intelligence and Native Rate Matching||VidyoTechnology is able to automatically adjust the quality, resolution and frame rate based on the availability, processing power and screen resolution. Additionally, Vidyo maintains the best possible quality without any freezing or tearing while network conditions are changing versus constant frame rate-resolution combination at legacy H.264 AVC endpoints.|
|Vidyo Independence||VidyoTechnology allows each endpoint to negotiate rates and resolution independently of the other participants in the conference. This allows every participant to have the best video quality possible without having to lower video quality to the lowest common denominator.|
|Vidyo IP Error Resilience||VidyoTechnology can provide a good teleconferencing experience while facing 15-20 percent packet loss. Legacy H.264 AVC products become useless and break down in when than packet loss exceeds two to three percent.|
|Vidyo End to End Delays||The VidyoRouter introduces a delay lower than 20ms. Overall, the VidyoTechnology implementation has significantly lower end to end delays than legacy AVC endpoints. Typical end to end latency for multipoint conference on a VidyoRouter is less than 250ms. This is extremely low compared to legacy videoconferencing systems, which can experience end to end multipoint latency at close to 500 ms.|
|Vidyo Ease of Use||Vidyo provides an intuitive interface that dynamically adjusts the layout as users join or leave the conference. The users can toggle between different modes and numbers of remote users with one single click. Regular users are able to set up and join conferences without the need for a special operator—a capability few legacy videoconferencing products possess.|
|Vidyo Redundancy||With VidyoTechnology, adding redundancy involves just adding another low cost VidyoRouter, while retaining existing licenses. For comparison with legacy MCU products a complete MCU with identical capacity needs to be acquired if redundancy is desired.|
|Vidyo Security||Vidyo supports secure conferencing thanks to the use of AES 128-bit encryption.|
|Vidyo Low Cost per Conference Line||Vidyo Technology requires less hardware, thus significantly lowering the costs per active line.|
|Vidyo Savings: No need for MCU. No need for Room ports.||VidyoTechnology does not require an expensive MCU to create a multipoint conference. Unlike traditional videoconferencing solutions, Vidyo’s room-based endpoints do not require any additional licenses.|
