The invention discloses a video content retrieval method and device based on television system voice interaction and a terminal, and relates to the technical field of video processing, and the method comprises the steps: when a video is played for the first time, extracting a picture frame from the video at a preset frequency, converting the picture frame into a multi-dimensional image feature vector and a corresponding video timestamp, and carrying out hierarchical storage in a database, constructing vectorized data containing visual semantic information; obtaining a voice retrieval instruction, performing intention recognition and semantic understanding, extracting a detection keyword, and generating a multi-dimensional retrieval feature vector; calculating a matching degree between the multi-dimensional retrieval feature vector and a multi-dimensional image feature vector of a video picture frame stored in a database, and screening out picture frames of which the similarity is higher than a preset similarity threshold to form a retrieval candidate matching set; and determining matched picture playing. The video content retrieval method is efficient, accurate and high in interactivity, and retrieval experience and operation efficiency of the user in the video watching process are remarkably improved.

Embodiments of the present disclosure disclose a virtual information display method, device, electronic equipment and computer readable medium. A specific embodiment of the method comprises: in response to detecting a selection operation on a virtual reality module, performing initialization processing on virtual smart guide information to be displayed and each item information to obtain initialized virtual smart guide information and an initialized item information set; determining a current virtual information display mode; rendering and displaying the initialized virtual smart guide information and the initialized item information in the initialized item information set according to the virtual information display mode to obtain a virtual smart guide image and a rendering scene; determining a current target virtual item in each virtual item displayed in the rendering scene; and displaying information of the current target virtual item by using the virtual smart guide image. The embodiment can improve the display efficiency of information.

The invention discloses an interaction method of an intelligent assistant, a man-machine interaction system and a related device, when the intelligent assistant is not awakened, a first function module is displayed on a man-machine interface at a first display definition, and a virtual image of the intelligent assistant is displayed on the man-machine interface at a second display definition. Therefore, the first function module is clearly displayed on the human-computer interface, and the virtual image of the intelligent assistant is fuzzily displayed. If the awakening operation for the intelligent assistant is obtained, the intelligent assistant is controlled to enter an awakening state, the virtual image of the intelligent assistant is displayed on the human-computer interface with the third display definition, and the first function module is displayed on the human-computer interface with the fourth display definition, so that the virtual image of the intelligent assistant is clearly displayed when the intelligent assistant is awakened. Therefore, when the intelligent assistant is not awakened, it is avoided as much as possible that the virtual image of the intelligent assistant distracts the attention of the user on the function module and shields the function module, and the display effect and operation convenience of the function module are improved.
