Dual-Stream Protocol - Yealink VC400 Administrator's Manual

Dual-Stream Protocol

To enhance the process of communicating with others over video, the dual-stream protocol
provides the ability to share content from a computer, such as video clips or documentation.
Both the video and the documentation can be transmitted to the far site simultaneously, thus
meeting the requirements of different conference scenarios, such as training or medical
consultation.
The Yealink video conferencing system supports the standard H.239 protocol and BFCP (Binary
Floor Control Protocol). H.239 protocol is used when sharing content with the far site in H.323
calls. BFCP protocol is used when sharing content with the far site in SIP calls. Before enabling
the desired protocol, ensure that the protocol is supported and enabled by the far site you wish
to call. If the far site does not support the protocol for sharing content, MCU will automatically
mix the content and camera video, and send them in one channel. For more information on mix
sending, refer to
Dual-stream protocol parameters on the system are described below.
