Abstract: 본 발명은 비디오 압축 시스템 내에서 가변 비트 레이트(variable bit rate: VBR) MPEG-2 인코딩을 수행하기 위해 제공된 실시간 단일 패스 가변 비트 레이트 제어 방법에 관한 것이다.  프레임 시퀀스에 대하여, 비디오 간격(즉, 화상 그룹(a group of picture: GOP))의 인코딩 난이도 수준은 인지 레이트 양자화 모델에 의해 결정된다.  이 모델은 각 비디오 간격에 복합(composite) 곡선을 할당하고, 이 복합 곡선에서 비디오 간격에 대한 비트수가 추정된다.  추정은 이전 인코딩된 비디오 간격에서 얻은 파라미터를 사용하는 임시 예측 모델에 의존한다.  분석중인 비디오 간격의 전체 레이트를 기초로 각 화상 유형의 R-Q 관련성이 갱신되고 화상 비트들이 할당된다.  장면 천이와 불안정성에 각각 예를 들어 비선형 메디안 필터와 로우 패스 필터를 적용함으로써 가변 비트 레이트 제어 방법을 확실히 보장할 수 있다.

Abstract: PURPOSE: An ink jet print head is provided to reinforce contact force between an ink jet print head and other structures such as barrier layers of an ink chamber and a heating chamber and to prevent leakage of ink and working liquid through the reinforcement of the contact force. CONSTITUTION: In an ink jet print head, an SiO2 protective film(2) is formed on a silicon substrate(1) and a heating layer(11) is provided on the protective film. An electrode layer(3) is formed on the heating layer to feed electric energy to the heating layer. The electrode layer is connected with a common electrode(12) and the electric energy is converted into thermal energy by the heating layer. Therefore, a barrier layer(7) of an ink chamber is changed into a firm adhesive material. When the barrier layer is assembled with the membrane, the barrier layer(7) keeps combining force between itself and a membrane without an additional combination-inducing layer.
