摘要： Disclosed are video conferencing systems, devices, architectures, and methods for transcoding, transrating, and the like, to facilitate video streaming in a distributed arrangement. An exemplary translator in accordance with embodiments can include: an input configured to receive a first video stream in a first format, the first video stream being from a first media switch, the first media switch being associated with a first stream group having one or more first endpoints; and an output configured to provide a second video stream in a second format, the second video stream being sent to a second media switch, the second media switch being associated with a second stream group having one or more second endpoints, whereby the translator is configured to convert from the first to the second format. Further, the translator can be configured as a logical endpoint where a first interface having an input/output pair uses the first format and a second interface having another input/output pair uses the second format. The two formats may differ in at least one characteristic.
