a series of color patterns etc if it isn 39 t a request to change the color pattern of the bezel 50 then the command is tested to determine if it is a request to turn on meta data 60 if it is in this example a meta data flag is set 64 the use of this flag is described with fig7 if it isn 39 t a request to use meta data 60 then the command 30 is tested to determine if it is a request to turn off the bezel 70 if it is in this example the bezel is turned off 74 if it isn 39 t a request to turn off the bezel 70 processing continues this is but one example of a program running in the processing element 100 that controls the color and or brightness of the bezel illumination 20 other methods either more or less complicated are anticipated for monitoring various internal and external parameters and settings referring to fig7 a second chart of the present invention will be described this is an exemplary program flow executed within the processing element 100 periodically e g at fixed intervals or at a particular instance such as during re trace etc first the meta data flag is tested to see if it is enabled 80 if not enabled the flow is done if it is enabled 80 the meta flag is tested to determine which type of meta data is to be used in controlling the bezel color 80 for example if the meta data is set to use the current channel 82 then the color of the bezel 10 is set based on the current channel being.
