The embodiment of the invention discloses a determination method. The method is applied to a terminal. The method comprises the following steps of downloading and playing a playing object under the first network type; judging whether the terminal is in a charging state or not, when the terminal is in the charging state, downloading and playing the playing object under the first network type, and when the terminal is not in the charging state, determining the network type of the terminal according to the buffer position of the playing object in downloading, and downloading and playing the playing object under the determined network type. The embodiment of the invention further provides a terminal and a computer storage medium.

The embodiment of the present application discloses a determination method, which is applied to a terminal, and the method includes: when downloading and playing a playback object under the first network standard, judging whether the terminal is in a charging state, and when the terminal is in a charging state, maintaining Download and play the playback object under the first network standard. When the terminal is not in the charging state, determine the network standard of the terminal according to the buffer position of the playback object during downloading, and download and play the playback object under the determined network standard. The embodiment of the present application also provides a terminal and a computer storage medium at the same time.

The invention discloses an adaptive video digital steganography method, which comprises the following steps of: a, decomposing a video file into frames I and B&P; b, selecting a macro block in rapid motion according to the magnitude of motion vectors of macro blocks in the frame B&P; c, selecting a texture region in the frame I; d, embedding secret information into the motion vector of the macro block; e embedding control information into the texture region; and f, synthesizing the frame B&P with steganography of the secret information and the frame I with steganography of the control information into a secret loading video file. According to the video digital steganography method disclosed by the invention, by means of embedding the secret information and the control information into the motion vector and the texture region respectively, the advantages of large embedded information amount, no influence to video quality, simplicity to operation and reliable performance are achieved. The video digital steganography method disclosed by the invention not only keeps pace with the development of the information security industry in China to advance the situation, but also brings remarkable social and military benefits, and has an extremely wide industrialized development prospect.

A follow-up illuminating free stereo video image display is disclosed. The display comprises: an audience pupil position acquisition apparatus (an infrared source and an infrared camera), which is used to collect left and right pupil position information of all the audiences and does not affect the audiences to watch an image; an image display device (a transmission-type liquid crystal display), which is used to display the externally input left and right video images in a time sharing mode; a back-light follow-up lighting device (comprising a light source array, a laminated light guide plate and a cylindrical surface lens array), which is used to divide a backlight lighting beam into left and right two beams so as to achieve alternative illumination, wherein one beam follows movement of the left pupils of the audiences and the other beam follows the movement of the right pupils of the audiences. The beams and the left and right video images which are displayed in the time sharing mode are switched synchronously. The left image is projected to the left pupils of all the audiences and the right image is projected to the right pupils of all the audiences so that the audiences can watch the video stereo images without crosstalk. The audiences can independently set a 2D or a 3D mode. The highest transverse resolution is a physical resolution of the liquid crystal screen.

The invention discloses a panoramic video distributing method and system based on visual characteristics. According to the method, visual characteristics of human eyes and network congestion conditions are used, and multi-path code streams formed by splicing panoramic videos are distributed adaptively. Thus, the watching effect of audiences is not influenced, and the playing smoothness of panoramic videos is improved.

Disclosed are a method and a device for loading applications. The method for loading applications comprises the following steps: extracting application information from a program stream of a hybrid broadcast / broadband TV, the application information comprising names of applications and program information about the applications; acquiring a pre-stored weight list; and acquiring, according to the weight list, weights corresponding to the application information, and sending, according to a sequence of the weights from high to low, the application information to a browser, so as to facilitate loading of the applications in the application information according to the sequence by the browser. The present invention can greatly reduce the loading pressure of a browser, accelerate the loading speed of the browser and increase the response speed of a hybrid broadcast / broadband TV.
