Binary Protocol for DVBStreamer===============================All integers will be in network byte order (ie big endian)Authentication will be used for changing channel adding pids/services etc, once aconnection has successfully sent an AUTH message that connection will be allowedto change channels/add outputs etc.The primary service is identifyable in the service filters list by the name"<Primary>".Common Types------------         -----------------------------STRING = |Length (Uint8)| Characters |         -----------------------------IPPORT == STRING Where the string is expected to be in the format (IPv6) [::::]:UDPPort or (IPv4) x.x.x.x:UDPPort.Message Codes-------------1 Character describes type and whether it requires authentication.AUTH = Authenticate messageCxxx = Control MessagesSxxx = Status MessagesRxxx = Response messagesMessage Header--------------2 byte Message Code2 byte Message Length	-----------------------------------------------                  -	|Message Code (uint16) | Data Length (uint16) | <--- DATA --->   |	-----------------------------------------------                  -Rxxx Standard Response Messages-------------------------------RERR = Response Error	DATA	-----------------------------------------	| Code (uint8) | Message string (STRING)|	-----------------------------------------Code------CODES-START--=RERR0x00 = OK            = Success0x01 = NOTAUTHORISED = Not authorised0x02 = EXISTS        = Output Already Exists0x03 = NOTFOUND      = Not found0x04 = STREAMING     = Already streaming to requested ip:port0xFF = GENERIC       = Generic Error (see message)--CODES-END--AUTH Authentication Message---------------------------AUTH = Authenticate	DATA	---------------------------------------	| Username (STRING)| password (STRING)|	---------------------------------------	Password is in plain text (not ideal but should be ok for the moment)	Responses : RERRINFO Information Message------------------------INFO = Information message	DATA	----------------------------	|Field to Retrieve (uint8) |    ----------------------------	Responses: RERR (OK, with message string containing the data)Field IDs-----------CODES-START--=INFO0x00 = NAME          = Name (user defined) of this server0x01 = FETYPE        = Front End Type0x02 = AUTHENTICATED = Is connection authenticated = "Authenticated" or "Not authenticated"0xFE = UPSECS        = Uptime string in seconds ie "61" == 1 Minute 1 Second.0xFF = UPTIME        = Uptime string "%d days %d hours %d minutes %d seconds"--CODES-END--Cxxx Control Messages---------------------CSxx = Control Service messagesCSPS = Control Service Primary Select - Select Primary Service	DATA	-----------------------	|Service Name (STRING)|	-----------------------	Responses : RERRCSSA = Control Service Secondary Add - Add secondary service	DATA	-------------------------------------------------------	|Service Output Name (STRING)| Output Address (IPPORT)|	-------------------------------------------------------	Responses : RERR (Output already exists, Already Streaming to IP:Port)CSSS = Control Service Secondary Select - Select a secondary service	DATA	-------------------------------------------------------	| Service Output Name (STRING) | Service Name (STRING)|	-------------------------------------------------------	Responses : RERR (No Such Output)CSSR = Control Service Secondary Remove - Remove secondary service	DATA	------------------------------	|Service Output Name (STRING)|	------------------------------	Responses: RERR (No Such Output)COxx = Control Output messagesCOAO = Control Output Add Output - Add a new output destination	DATA	-----------------------------------------------	| Output Name (STRING)|Output Address (IPPORT)|	-----------------------------------------------	Responses : RERRCORO = Control Output Remove Output - Remove an output destination	DATA	-----------------------	| Output Name (STRING)|	-----------------------	Responses : RERRCOAP = Control Output Add PIDs - Add pids to an output.CORP = Control Output remove PIDs - Remove pids from an output.
