ABSTRACT:
Methods and systems for generating alternate and zigzag address scans in a reconfigured two-dimensional map under the MPEG-1 and MPEG-2 are provided. In one embodiment, a control signal generator determines the subsequent alternate address based on the present alternate address. In another embodiment, the control signal generator determines the subsequent zigzag address based on the present zigzag address. The subsequent address is generated by incrementing, decrementing, or resetting a pair of up/down counters that are coupled to the inputs of the control signal generator.
