Based on the overall situation of Shanghai's cultural development, this plan will restore and protect a series of precious old images representing Shanghai's urban memory by using the creation ability of Knews short videos and massive image material library, as well as Tencent Multimedia Lab's "Light and Shadow Revitalizing" intelligent image restoration technology, so as to revitalize the urban memory. On September 27, the two sides released a rare historical video showing the development and changes of Pudong in recent decades, which has attracted wide attention.

Media + digital technology crossover integration, urban memory restoration has a new direction

Since the 1990s, in order to protect urban memory and cultural heritage for the purpose of "urban memory protection project" has been carried out in various places. Due to the establishment of urban image archive mainly through traditional means such as photography and photography, it is more and more difficult to solve the problem of massive restoration data and resource storage with the passing of time.

The precious images of Shanghai, carefully planned by generations of TV people in Shanghai TV station, have long become an indispensable part of Shanghai city culture. This "Shanghai Urban Memory Protection Project" brings a new idea of urban memory protection. On the one hand, Knews has rich experience in short video creation and a large number of video materials documenting urban development, which can show the multifaceted memory of a city through short video forms conducive to communication. On the other hand, with the help of Tencent Multimedia Lab self-developed light and shadow revitalizing intelligent image restoration platform, through a variety of self-developed artificial intelligence algorithms, the use of intelligent analysis, image quality restoration, image quality enhancement, intelligent coding and other digital technologies, make the classic old image revitalized.

For the 2021 National Day holiday, Tencent and Kankan Knews have worked together to restore the 1949 Shanghai National Day Parade and the 1930s and 1940s Shanghai street scene, sparking discussion and historical empathy. In addition, Tencent's "rejuvenating Light and shadow" intelligent repair technology has also successfully restored Leslie Cheung's Passion concert, Qian Xuesen's rare images of Hong Kong's return to the history 25 years ago, and Tencent Video's Kangxi Dynasty and Tianxia Renjia and other films and TV series, making many images with poor picture quality take on a new look.
