IPC: H04N19/00
Filed: 2001-12-27
Abstract: PURPOSE: To provide a data processing unit and method that can stably conduct processing even when macro blocks are discontinuous in the case of input of an I picture of an MPEG stream. CONSTITUTION: A VLD(Variable Length Decoder) 303 receives a reference MB(Macro Block) address generated by a timing generator 302 on the basis of a slice start code and a frame pulse detected from an input stream and the input stream whose phase is adjusted by a delay circuit 300, an address comparator 304 compares the reference MB address with an MB address detected by decoding the variable length code to check the consecutiveness of the MB addresses. When the MB addresses are discontinuous, a stream outputted from e.g. the VLD 303 is temporarily stopped and a selector 306 selects a position of a replacement data generating circuit 305. The discontinuous parts of the input stream are replaced with macro block data having correct MB addresses that have been already prepared by the replacement data generating circuit 305.

Abstract: PURPOSE: A hair transplanter is provided to minimize damage of a scalp due to insertion of a needle by forming the needle to have a pointed end portion and stably perform the hair transplantation by preventing damage of hair roots inserted into the needle. CONSTITUTION: A needle to be inserted into a scalp has a pointed end portion to reduce damage of the scalp, and a guide plate is adhered to an end portion of a sliding unit reciprocating in the longitudinal direction of the needle outside the needle, in order to prevent hair roots from being separated at the time of the separation of the needle. As a result, the hair roots inserted into a needle insertion groove are not damaged and are naturally settled in the scalp without modification, thereby stably performing the hair transplantation.
