Realization principle of sdi cameraThe principle of the implementation of the camera was as follows: the non-return-to-zero inverted scrambling code (NRZI) was used to replace the early block coding. The standards were SMPTE -259M and EBU-Tech- 3267, which included digital composite and digital component signals including digital audio. Before transmission, the original data stream was scrambled and converted into the NRZI code to ensure that the original data could be restored at the receiver. This could be regarded as a kind of base band signal modification. The SDI-interface could transmit 270Mb/s serial digital component signals, and for 16:9 format images, it could transmit 360Mb/s signals. The NRZI code is a polar sensitive code. It uses "1" and "0" to represent the high and low levels. If there are continuous "1" or continuous "0" for a long time, it will affect the receiver's extraction of the clock from the digital signal.(Because the serial digital signal interface does not transmit the clock signal alone, the receiving end needs to extract the clock signal from the digital signal stream.) Therefore, the NRZI code with "1" and "0" to indicate whether there is a level change. When receiving the NRZI code stream, as long as the level change is detected, the data can be recovered. Even if it is all "1" signals, the resulting signal frequency is only half of the original clock frequency. After scrambling, the chances of continuous "1" are reduced. This further reduced the high-frequency component. At the receiving end of the data stream, the original data stream was recovered from the NRZI stream by the PDI decode. The SDI-interface could not directly transmit compressed digital signals. After the compressed signals recorded by the digital video recorder, hard disk, and other equipment were replayed, they had to be uncompressed and output through the SDI-interface before entering the SDI-system. If it was repeatedly unpacked and compressed, it would inevitably cause the image quality to decline and the delay to increase. For this reason, various digital video recorder and non-linear editing systems of different format had their own interface for directly transmitting compressed digital signals.

Lixian Future Community NurseriesLixian Future Community's kindergarten had more complete facilities. The total land area is about 6017 square meters, the total construction area is about 11124 square meters, and the design scale is 12 classes. The overall design was ladder-shaped and stacked layer by layer. There was a large area of wood and white space. The style was simple and fresh. Each classroom was bright and had large floor-to-ceiling windows. When the door was pushed open, one could see the scenery. There was also a large platform outside each classroom and a tree. There were children's activity rooms, professional classrooms, multi-purpose halls, and so on. The roof was a large "playground" that would become the plant world of the kindergarten in the future, allowing children to be close to nature from an early age.

How about a horror novel?There were positive and negative aspects to reading suspense horror novels.
On the positive side, suspense horror novels were often full of ups and downs and suspense. They could greatly stimulate the curiosity and imagination of the readers and immerse them in the unique atmosphere built by the author. For example, some novels used unique narrative methods, such as the intersection of archives and reality, or the use of brain-burning deciphering as a plot to help train the reader's logical thinking ability. Moreover, many suspense horror novels incorporated local cultural elements. For example, Chinese horror novels contained Chinese logic and folk elements, which allowed readers to understand different cultural characteristics.
However, there was also a negative aspect. Some suspense horror novels may contain exciting content such as blood, violence, and horror. These contents may have a certain impact on the reader's psychology, especially for readers with weak psychological endurance. It may cause fear, anxiety, and other negative emotions, and even affect the quality of sleep. For example, some novels that create an overly strong horror atmosphere may make the reader not dare to turn off the lights and go to sleep after reading.
In short, whether or not a person could read a horror novel depended on their personal preferences, psychological endurance, and other factors.
