Description

Apparatus for providing video service {Apparatus for providing video service}

The present invention relates to a video service providing device.

In general, an online education service is a service that provides digital learning content so that anyone can perform desired learning anytime, anywhere using a network. Therefore, online education service users can learn regardless of location through online education services, and by repeatedly using desired educational contents, they can acquire the knowledge they need or prepare for exams through problem solving. Learning and evaluation can be performed.

In general, U-LEARNING is defined as an educational form in which students can learn what they want anytime, anywhere in their daily lives, regardless of time, place or environment, based on a ubiquitous learning environment. In other words, it can be seen as online education in a ubiquitous computing environment represented by PDAs, smart phones, and DMB.

These online education services mainly utilize Internet video lectures called 'in-gang (internet lectures)' and analog media called 'books' that are viewed by flipping papers. By the way, Internet video lectures are fun because they are video media, but they are not suitable for active learning because 1) you have to passively watch the instructor's lecture and 2) it's not easy to find the parts you don't understand. . On the other hand, in the case of a paper book, active learning is possible by turning the pages back and forth at will, but there is a disadvantage that learners get bored or lose concentration.

Therefore, the need for a futuristic educational medium that combines the advantages of 'Ingang', such as the rich fun of video media and the active learning possibility of 'paper books', is emerging.

In addition to 'Ingang', which provides direct education, recently, video contents such as movies, dramas, and entertainment can also have indirect educational effects, so they are widely used in foreign language education, job training, and liberal arts classes. Therefore, similarly to video contents such as movies, dramas, and entertainment, there is a need for future educational media that combines the advantages of the active learning potential of paper books with the rich fun that only video media provides.
