GS9090 Data Sheet
28201 - 1
July 2005
38 of 70
3.9.6.1 Video Standard Indication
As well as detecting the video standard, the GS9090 can extract the data format
being carried on the serial digital interface (i.e. SDTI, SDI, or DVB-ASI).
This information is represented by bits 0 to 3 of the DATA_FORMAT register
(
Table 3-7
), which may be read by the application layer via the host interface.
DATA_FORMAT[3:0] register codes are shown in
Table 3-10
.
The DATA_FORMAT[3:0] register defaults to Fh (undefined) after a system reset.
The register will also be set to its default value if the device is not locked (LOCKED
= LOW), or if both SMPTE_BYPASS and DVB_ASI pins are LOW.
3.9.7 Error Detection and Indication
The GS9090 contains a number of error detection functions to enhance operation
of the device when operating in SMPTE mode. These functions, except lock error
detection, will not be available in DVB-ASI mode (
DVB-ASI Functionality on
page 29
) or Data-Through mode (
Data-Through functionality on page 29
).
The device maintains an error status register at address 01h called
ERROR_STATUS. Each type of error has a specific flag or bit in this register that
is set HIGH whenever that error is detected (
Table 3-11
).
All bits in the ERROR_STATUS register, except the LOCK_ERR bit, will be cleared
at the start of each video field or when read by the host interface, whichever
condition occurs first.
