Sound Control Protocol for SpeechLine Digital Wireless

SSC Developer‘s guide for SpeechLine Digital Wireless | 52/109
SSC Method List (SL Multi-Channel Receiver DW)
Optional properties are:
• type string "Number", "String", "Boolean", or "Container"
• min number minimum valid value
• max number maximum valid value
• inc number recommended user interface increment value
• units string String describing value units (preferably SI)
• desc string descriptive text, meant for display to the user
• option string array of all allowed options for the value
• option_desc string array with description text relating to the option values
The language for "units", "description" and "option_desc" MAY depend on /device/language.
Examples:
TX: {"osc":{"limits":[{"device":{"led":{"brightness":null}}}]}}
RX: {"osc":{"limits":[{"device":{"led":{"brightness":[{"type":
"Number","writeable":true,"subscr":true,"const":false,"min":"0",
"max":"5","inc":"1","units":"","desc":"Method to set the leds
brightness"}]}}}]}}
TX: {"osc":{"limits":[{"audio":{"rx1":{"equalizer":{"preset":null}}}}]}}
RX: {"osc":{"limits":[{"audio":{"rx1":{"equalizer":{"preset":[{"type":
"String","writeable":true,"subscr":true,"const":false,"option":
["OFF","FEMALE_SPEECH","MALE_SPEECH","MEDIA","CUSTOM"],"option_desc":
["Equalizer preset Off","Equalizer preset set to female speech",
"Equalizer preset set to male speech","Equalizer preset set to media",
"Equalizer preset set to custom settings"],"desc":"Method to select
the equalizer preset for the channel"}]}}}}]}}
11.7 /osc/feature/pattern
Parameter type: Boolean.
Permission: Read only.
Pre-condition: N.A.
Post-condition: N.A.
Description: Support for address pattern matching is OPTIONAL for an SSC Server; it MAY be left out
in a restricted implementation. If the SSC Server does not support address pattern matching, it MUST
treat the special pattern characters like normal characters. An SSC Client can find out whether ad-
dress patterns are supported by receiving error replies, or by calling the SSC Method /osc/feature/
pattern
Example:
TX: {"osc":{"feature":{"pattern":null}}}
RX: {"osc":{"feature":{"pattern":false}}}
11.8 /osc/feature/baseaddr
Parameter type: Boolean.
Permission: Read only.
Pre-condition: N.A.
Post-condition: N.A.
Description: Using a baseaddr helps to explore a device in a truly interactive manner, and may addi-
tionally be used to reduce message lengths by shortening addresses in SSC requests.
A client may query /osc/feature/baseaddr to inquire whether the SSC Server supports setting a
method base address.
Example:
TX: {"osc":{"feature":{"baseaddr":null}}}
RX: {"osc":{"feature":{"baseaddr":false}}}
