The In-Band Status fields are:
Field	Description
Mode	The values displayed on the OSD are:
	ANALOG — analog (NTSC) channel
	64 QAM — 64 QAM digital channel
	256 QAM — 256 QAM digital channel
Carrier Lock	Indicates whether the in-band receiver is locked to the carrier. If a digital
	carrier is not present, it indicates the carrier is not locked:
	OSD		Front Panel		Description
	YES		L		Carrier locked
	NO		U		Carrier not locked
PCR Lock	Indicates		whether the in-band		receiver is locked to the current program clock
	reference for a digital video service on the specified tuner. If a digital carrier is
	not present, it indicates the PCR is not locked.
Data	Indicates whether data is being carried on the in-band stream. The indicators
	cover all packet processors regardless of the stream they are monitoring:
	OSD		Front Panel		Description
	YES		On		In-band data detected within last 5 seconds
	NO		Off		In-band data not detected within last 5 seconds
Frequency	The analog		frequency is displayed as the picture carrier. The In-band
	frequency is center RF carrier frequency tuned for the digital service on the
	specified tuner. The frequency is displayed in MHz in xxxx.xxx format and
	ranges from 54 to 860 MHz.
SNR	When carrier lock has been established, displays an estimate of the carrier
	signal-to-noise ratio in dB, with an explanation:
	GOOD—Good value
	FAIR—Marginal signal level, check the signal
	POOR—Unusable signal
	INVALID—Invalid SNR value
5 Second Error Counts	Indicates the number of correctable and uncorrectable digital multiplex errors,
	up to 9999. It is updated every 5 seconds and reset each time the DCH6416
	is power cycled or another digital multiplex is tuned. The maximum value
	displayed is 9999, even if there were more than 9999 errors.
