Systems and methods for processing composite video signals

A method for processing composite video signals, the method comprising:

• generating a line lock clock signal;
• generating source data associated with a source composite video signal, the source composite video signal being related to a source clock signal;
• storing the source data in a buffer based at least in part on the source clock signal;
• providing destination data from the buffer based at least in part on the line lock clock signal;
• processing the destination data to extract a synchronization component;
• determining a phase error between the synchronization component and the line lock clock signal;
• adjusting the line lock clock signal based at least in part on the phase error;
• and
• adjusting the source data based at least in part on the phase error.

A system for processing composite video signals, the system comprising:

• one or more data processors;
• and
• a computer-readable storage medium encoded with instructions for commanding the data processors to execute operations including:
• generating a line lock clock signal;
• generating source data associated with a source composite video signal, the source composite video signal being related to a source clock signal;
• storing the source data in a buffer based at least in part on the source clock signal;
• providing destination data from the buffer based at least in part on the line lock clock signal;
• processing the destination data to extract a synchronization component;
• determining a phase error between the synchronization component and the line lock clock signal;
• adjusting the line lock clock signal based at least in part on the phase error;
• and
• adjusting the source data based at least in part on the phase error.
