Lisa Bock covers translators and mixers, which are middleboxes placed in the network that transform the media stream within a session. Learn how they are sometimes necessary when handling conferencing sessions or traversing firewalls.
- [Instructor] When transmitting multimedia…over a complex network, as seen in this graphic,…it's important that all sites receive the data…in the correct format.…Translators and mixers are middleboxes…that are placed in the network…that transform the media stream within a session.…They're sometimes necessary…when handling conference sessions…or traversing firewalls.…Translators transform RTP media…as it passes through a network…to better suit the characteristics…of the output network.…
