Following methods are used for DMI CEC module.

Name	Parameters	Description
setEnabled	enabled : boolean	Enables or disables CEC
getEnabled	none	Returns true if CEC is enabled
setName	name : string	Sets the name of the STB device. The default name is "STB". It is recommended that the name of the device is set prior to enabling CEC.
getName	none	Returns the name of the STB device
sendMessage	message : String	The message is a base64 encoded byte array of the raw CEC bytes. The CEC message includes the device ID for the intended destination.
getCECAddresses	none	return the JSON object <CECAddresses> that is assigned to the local device. It does not contain the <CECAddresses> of other devices on the connected CEC network.
getCECAddresses	none	"CECAddresses" : { "physicalAddress": Array of 4 bytes [byte0, byte1, byte2, byte3], "logicalAddresses" : Array of <CECLogicalAddress> } "CECLogicalAddress" : { "deviceType" : <string> "logicalAddress": <integer> } The deviceType returned is part or all of devices types optionally set by XRE. A CEC device can have multiple deviceTypes, if so an array of <CECLogicalAddress> with size more than one is returned. Default deviceType is Tuner, and its logical Address is either 3, 6, 7, or 10. In messages sent by XRE, XRE can only use the logicalAddress returned from CECAddresses. Accepted deviceType are: "Tuner", "Record", "Playback", "AudioSystem", "VideoProcessor", "Switch"
