QUES: LaserDisc was a composite video format: the luminance (black and white) and chrominance (color) information were transmitted in one signal, separated by the receiver. While good comb filters can do so adequately, these two signals cannot be completely separated. On DVDs, data is stored in the form of digital blocks which make up each independent frame. The signal produced is dependent on the equipment used to master the disc. Signals range from composite and split, to YUV and RGB. Depending upon which format is used, this can result in far higher fidelity, particularly at strong color borders or regions of high detail (especially if there is moderate movement in the picture) and low-contrast details like skin tones, where comb filters almost inevitably smudge some detail.

What device seperated the black and white and color signals in LaserDiscs?
What is the answer?
ANS: the receiver
QUES: To allow for greater movement while dancing and singing, Madonna was one of the earliest adopters of hands-free radio-frequency headset microphones, with the headset fastened over the ears or the top of the head, and the microphone capsule on a boom arm that extended to the mouth. Because of her prominent usage, the microphone design came to be known as the "Madonna mic". Metz noted that Madonna represents a paradox as she is often perceived as living her whole life as a performance. While her big-screen performances are panned, her live performances are critical successes. Madonna was the first artist to have her concert tours as reenactment of her music videos. Author Elin Diamond explained that reciprocally, the fact that images from Madonna's videos can be recreated in a live setting enhances the realism of the original videos. Thus her live performances have become the means by which mediatized representations are naturalized. Taraborrelli said that encompassing multimedia, latest technology and sound systems, Madonna's concerts and live performances are deemed as "extravagant show piece, a walking art show."

Whose concerts are extravagant live shows?
What is the answer?
ANS: Madonna's
QUES: It has pleased western historians to write of a decline of the Ottoman Empire as though a stable and uncontested polity of that name once existed. The borders did expand and contract but they were always dynamic and always in "question" right from the beginning. The Ottoman Empire was created from the lands of the former eastern Roman Empire on the occasion of the latter's violent demise. The last Roman emperor died fighting hand-to-hand in the streets of his capital, Constantinople, overwhelmed by the Ottoman military, in May, 1453. The victors inherited his remaining territory in the Balkans.

What was always in question from the beginning of the Ottoman Empire?
What is the answer?
ANS:
The borders
