[Q]: Extract the answer to the question from the following context. Question: A recording of moving visual images on tape or digital is called. Context: It was only in the 1980s that digital telephony transmission networks became possible, such as with ISDN networks, assuring a minimum bit rate (usually 128 kilobits/s) for compressed video and audio transmission. During this time, there was also research into other forms of digital video and audio communication. Many of these technologies, such as the Media space, are not as widely used today as videoconferencing but were still an important area of research. The first dedicated systems started to appear in the market as ISDN networks were expanding throughout the world. One of the first commercial videoconferencing systems sold to companies came from PictureTel Corp., which had an Initial Public Offering in November, 1984.

[Q]: Extract the answer to the question from the following context. Question: What was it considered when the language returned? Context: The Czech people gained widespread national pride during the mid-eighteenth century, inspired by the Age of Enlightenment a half-century earlier. Czech historians began to emphasize their people's accomplishments from the fifteenth through the seventeenth centuries, rebelling against the Counter-Reformation (which had denigrated Czech and other non-Latin languages). Czech philologists studied sixteenth-century texts, advocating the return of the language to high culture. This period is known as the Czech National Revival (or Renascence).

[Q]: Extract the answer to the question from the following context. Question: What is the difference between the singals? Context: If the data to be compressed is analog (such as a voltage that varies with time), quantization is employed to digitize it into numbers (normally integers). This is referred to as analog-to-digital (A/D) conversion. If the integers generated by quantization are 8 bits each, then the entire range of the analog signal is divided into 256 intervals and all the signal values within an interval are quantized to the same number. If 16-bit integers are generated, then the range of the analog signal is divided into 65,536 intervals.

[Q]: Extract the answer to the question from the following context. Question: What is wood used for? Context: Wood has always been used extensively for furniture, such as chairs and beds. It is also used for tool handles and cutlery, such as chopsticks, toothpicks, and other utensils, like the wooden spoon.
