HDCVI was developed by Dahua and is being licensed to other manufacturers both directly and via the HDcctv Alliance as HDcctv 2.0 AT.

HD-TVI was developed by Techpoint, a U.S. semiconductor manufacturer. It has been licensed to Dahua's largest competitor, Hikvision, among others.

AHD is developed by Korean Nextxhip for beating CVI and TVI

HDCVI ( High Definition Composite Video Interface) is a solution for megapixel high definition applications, featuring non-latent long-distance transmission at a lower cost. The name has to do with its baseband and quadrature amplitude modulation technology, which is able to avoid CVBS cross talk, completely separate brightness and hue signal, and further enhances video quality.

Better Anti-Interference Capability:

The anti-interference capability of HD-SDI solution is relatively poor when been placed against high-frequent radiation environment, which could lead to higher bit error ratio while the HDCVI adopts low-frequency modulation technology, making it free from the high-frequency wireless electric radiation to ensure stable video transmission at high image quality.

음.. 외국꺼라 피트인가?

아무튼 500m 정도 전송가능한 규격으로

HD-SDI가 150m 정도가 리피터 없이 보낼수 있는 한계치 이기에 거리로 인한 메리츠가 존재하는 듯

(어쩌면 거리가 전부일지도)

이번에 위키 다시 좀 해보려고 했는데...

FCKEditor가 1.22로 올린 상황에서 안되길래 확인해보니..

1.17 버전까지만 사용이 가능하다고.. OTL

위키피디아에서 사용하는 편집기는 좀 불편한데..

1.17 버전의 mediawiki를 사용해서 FCKeditor를 쓰거나

TinyMCE를 쓰는 정도가 그나마 차선책일지도..

snappy SD 카드에

kernel.img를 바꾸니 무한 재부팅 -_ㅠ

config.txt에

kernel=kernel.img

이런식으로 넣으니 그냥 깜깜 무소식 -_-

음... make modules_install을 안해주고 해서 그런가?

2015.04.16 추가

시리얼 연결해서 머가 문제인지 확인

일단.. snappy의 경우 kernel.img는 바꾸어도 차이가 없고

kernel7.img를 바꾸어야 변화가 생긴다. 아마도 kernel7.img가 ARMv7용인듯 하다.

Uncompressing Linux... done, booting the kernel.

그러니까.. 저 zImage 파일을 다른걸로 이름 바꿔서 테스트 하면 되는거군?!

심심해서(일하기 싫어서) 한번 자료를 긁어서 엑셀로 그려보니..

IMF의 여파가 어마어마 하긴 했구나 싶다.

일단.. IMF 종료가 2001년 이었음에도 불구하고 그 이후로 한 5년간은 혼란기였기에

출산율 자체는 1994년에서 2005년 까지 10년간 계속 하락이었고

1997년 IMF가 시작되더라도 하락세가 두드러지게 커지진 않았다.

아무튼.. 그러한 혼란기 이후에는 경제가 성장한다거나 해서 바로 적용되는건 아닐테니

출산율이 회복되거나 악화되는건 최소한 5년 정도의 지연시간을 지닌다고 봤을때

전 정권의 상황에 따라 다음정권의 출산율이 반영된다고 보면 되려나?

아무튼.. 김영삼 당시에 하락은.. 이전 정권인 전두환일테고

김대중 당시 하락은 김영삼의 IMF 여파 -_-a 정말 욕밖에 안나오는구만..

노무현 당시 하락과 반등은 IMF 구조조정의 극복

그리고 이명박 당시의 하락과 반등은 안정화 정도 이려나?

아무튼.. 그 이후 몇년 지나지 않아 통계값이 유의미 하진 않겠지만

출산 증가율이 멈추거나 혹은 하락세...가 아닐까 생각이 된다.

아래 그래프는 년도별 출생자 수

요건 학년별 출생시기 역산을 통한 학생수 분포

IMF 2~3년간은 그나마 출산이 유지/늘었지만 그 이후로는 급락해서

IMF 극복을 이야기 한 4년 후인 2004년 까지도 입학생 수가 늘지 않았다.

아래 그래프는 2014년 학년별 학생수

내년 부터는 이제 이명박 정부당시 태어난 아이들이 입학을 할 시기인데..

2017년에는 또 한번 대폭 줄어들게 될테니.. 어찌 될랑가...

찾아는 봐도 이런것 관련 내용은 아직인데..

현상으로만 봐서는..

#ifdef 와 #if defined () 가 동일한 의미이고

#ifdef () 는 다른 의미로 사용이 가능한게 아닐까 생각된다.

에러를 보니.. identifier.

간단하게 식별자로 ()가 들어갈 수 없는데 ( 부터 식별자로 인식을 해버리는 것으로 생각된다.

즉.. #ifdef {A-Za-z0-9_} 라고 정의가 되려나?

#define과는 다르게 #ifdef에서는 ()를 쓸수가 없다! 가 결론일듯
