Functional Description
22/113
Note 1: Codes 110 and 111 are associated with “No Standard”.
From this list of possible standards, the user must complete the Automatic Standard Recognition
table required for the automatic search. Identification will be restricted to the table entries and the
first entry will be tried first. Entering code 110 or 111 in the Automatic Standard Recognition table
terminates the standard sequence search. It is possible to enter several times the same code. The
Automatic Standard Recognition table and its default values are presented in
If the default values are used, code 111 (no standard) is the fourth entry and the standard
identification will be restricted to the first three standards (in order PAL BGDHI, SECAM and
NTSC M).
Each standard recognition trial period lasts 2 fields. All trials corresponding to table entries are
performed. The identification decision is based on the results of the trials and a single table entry
should be identified. If two entries are identified by error, the standard recognition sequence will re-
start from the beginning of the table and no standard will be identified.
The DDECCONT4[5:0], DDECCONT3[5:0], DDECCONT2[5:0], and DDECCONT1[5:0] registers
are used to program the Automatic Standard Recognition table.
After the sequence search, a second step (also called a confirmation step) is performed by the
algorithm. It is performed on the single identified Automatic Standard Recognition table entry. It is
possible to program the number of fields where the standard identification must be confirmed before
the status flags are modified. The confirmation code is described in
The confirmation code is programmed in the STI_NB_FIELDS_CONFIRM[2:0] bits of the
