The hierarchical image classification method derives a coarse classification result of an image by analyzing the image according to a coarse classification model, derives at least one fine classification model by inquiring a classification relation table according to the coarse classification result, derives at least one level information by inquiring a level relation table according to the at least one fine classification model, retrieves at least one coarse feature descriptor from the coarse classification model according to the at least one level information, and decides at least one fine classification result according to the at least one fine classification model and the at least one coarse feature descriptor. The hierarchical image classification method may inquire the classification relation table and the level relation table repeatedly to continuously decide other fine classification result(s).

Abstract: A recognition system includes an image capturing device and a server. The image capturing device generates a Mth-layer calculation result based on image data and a convolutional neural network (CNN), and transmits feature information associated with the Mth-layer calculation result. M is a positive integer, M is equal to or greater than 1, M is less than or equal to N, and N is a predetermined positive integer. The server receives the feature information. The server generates a Kth-layer calculation result based on the feature information and the CNN by an iterative method when M is less than N. K is a positive integer which is greater than M and less than or equal to N. The server generates a first recognition result associated with the image data based on the Kth-layer calculation result and a first recognition model when K is equal to N.

Abstract: The disclosure is related to a method for calibrating an interactive time in a live program, and a system thereof. In the method, a user device is used to receive a live content embedded with a mark from a live program system. A signal processing scheme is performed to identify the mark so as to obtain a marking time. Then an interactive content is received from an interactive serving system. An initiating time of interactive activity is obtained. A time difference between the marking time and the initiating time is counted. The time difference is referred to for calibrating the time of issuing an interactive message when responding to the interactive activity. The responding time, at the system side, is restored to an actual time. Therefore, the method effectively excludes the time error for responding to the interactive activity in the live program due to transmission delay.

Abstract: A distributed multimedia recognition system comprises a user equipment and a server platform, wherein the user equipment is connected to the server platform. The user equipment transmits a recognition request, and performs characteristic extraction on a multimedia, so as to obtain characteristic data. The server platform receives the recognition request, selects one or multiple batches of corresponding reference characteristic data among multiple batches of reference characteristic data recorded in a characteristic database thereof according to a condition of the recognition request, and sends the one or multiple batches of the corresponding reference characteristic data to the user equipment. The user equipment compares the characteristic data to the one or multiple batches of the corresponding reference characteristic data to obtain a recognition result.

Abstract: A method for providing the second screen information is disclosed. The second screen information is used to be displayed on a portable device which includes a plurality of application software. While a link between the display equipment and a server is established, an environment data is generated by one of the display equipment and the portable device according to a using information where a user is viewing the display equipment. According to the environment data, the portable device may receive network information, which is sent out by the server, to execute one of the application software of the mobile device.

Abstract: In interactive advertisement offering method and system, a server wirelessly receives from a user terminal an input signal, which is associated with a target TV advertisement viewed by a user of the user terminal. Upon identifying one TV advertisement to be the target TV advertisement based on the input signal, the server determines one of pre-stored Internet advertisements as a reference advertisement based on key terms representative of the target TV advertisement, and then transmits to the user terminal a reference advertisement menu generated thereby along with pre-stored Internet advertisement content corresponding to the reference advertisement for display of the reference advertisement menu on the user terminal.

Abstract: In a method for controlling channel-switching, a current channel is displayed through a display unit. A channel-switching correlation table is looked up to obtain at least one candidate channel, which is predicted to be watched after the current channel. The current channel is switched to the at least one candidate channel when a channel-switching signal is received, such that the display unit displays the at least one candidate channel. The present invention also discloses a device for controlling channel-switching and a non-transitory computer-readable storage medium for storing the method for controlling channel-switching.

Abstract: A data displaying device for bidirectionally communicating with a far end service station by wired or wireless way is disclosed. According to the data sets displayed on the screen. the data displaying device selectively emits a request updating signal to a service station to request the service station to transfer part of updating data. Thus, the service station may reduce the transfer data amount greatly, thus the load of bandwidth is decreased. When a request updating signal is emitted to a service station, the data range of requesting a service station to send ordered updating data includes a data range of screen display.
