Concepts of YNCA and YNC
YNCA protocol is designed to provide a simple structure of controlling commands for Yamaha AV products. The "YNCA" derives from the fact that all its commands are the aliases of YNC (Yamaha Network Command) protocol. YNCA command set is a reduced one of YNC’s but still offering powerful functionalities for operating Yamaha AV products. This information is intended to provide clarifications on differences between YNCA and YNC protocols hoping that would help you to choose the right protocol which suits your application best.
- YNCA Features
- Simple: No ACK/NAK handshaking
- Short texts and simple syntax: Complicated/heavy parser module as XML not required
- Common protocol for both Network(Ethernet) and RS-232C connections: Easy to port each other
- Peer-to-peer connection: Not necessary for multi-connection management
- Auto feedback: Status changes are always pushed out, requires no polling
- Sufficient command set: For complete daily operations and for some settings
- YNC Features * Please see the accompanying file for details.
- Standard XML format: Parsers from standard libraries can be used
- HTTP: Used widespread as a standard method for multi-client control environment
- Covering all YNCA command sets: Sufficient enough for daily use operations
- Detailed command sets available: for DSP/PEQ parameters, Video Adjustments and so on
