Ansivision is transmitted from server to client via TCP/IP. A backchannel is not provided.
The same data-packets are send to all connected clients. The underlying transmission protocol requires that the data is send to all clients consecutively, but this timespan can be neglected compared to the delivery time in the average case.
Data is send to the client in realtime, or (if possible) with slight forerun. A client that is exposed to higher latency should use a buffer in order to compensate this.
All data is send in exactly the form they are available. There is no chunking. Data relying on timing-critical display can contain additional timing-information not defined in ANSI X3.64.
