An important challenge is applying a methodology capable of creating advanced TV
beam validations. Simply checking the beam's binary values, while able to identify
many problems, could not identify all types of errors. In addition to this type of
verification, there are several possibilities for errors generated during multiplexing, for
example errors such as inconsistencies when crossing information between different
tables, errors due to the order or frequency in which some tables are transmitted, and
errors in synchrony and time data are complex cases that can be identified
automatically.
To perform the verification of the TV beam, an automation method will be developed
that will receive the content transmitted by the broadcaster as input and will execute
several algorithms to compare the received data with the expected values defined by the
Brazilian Digital TV standard. After comparison the algorithm will notify if the beam is
in disagreement with the expected one and will inform you which problems were
encountered.
The resulting solution should be used by product engineering teams when analyzing
problems in the field. In several situations where there are errors in the reception of TV
signals, it is necessary to capture the transmitted signals and thoroughly investigate the
data, checking each table of the beam. The system will automate and facilitate this
operation.
