Abstract
Presented herein are system(s), method(s), and apparatus for detecting end of slice groups in a video bitstream. In one embodiment, there is presented a circuit for extracting a data structure from one or more data words. The circuit comprises a multiplexer, a bit pointer, a first logic circuit, and a comparator. The multiplexer provides one or more bits from the one or more data words. The bit pointer points to the bits following the provided one or more bits in the one or more data words. The first logic circuit examines at least portions of the data words for an end of data structure code, the at least portions comprising the one or more bits, and provides an indicator indicating the position of the end of data structure code. The comparator compares the indicator to where the bit pointer points.
