The invention discloses a positioned advertisement playing method for a global positioning system (GPS). A taxi, a taximeter arranged in the taxi, an advertisement playing device, a Bluetooth device arranged in the advertisement playing device, the GPS arranged in the taximeter and a server arranged in a dispatching center are adopted in the method. The method comprises that: the advertisement playing device downloads inter-cut files through the GPS according to the running position of the taxi; according to the size of the inter-cut files, the downloading has two modes, namely downloading of a GPS terminal and downloading of the advertisement playing device; and after the contents are completely played, if an engine is started, the taximeter is started, and the GPS sends information 'Y' which expresses that the passenger is still in the taxi to the server so as to continue the previous played contents, otherwise, continue playing the contents which are not completely played. According to the method, the advertisement has flowability, instantaneity, dynamic effect and sound effect; and the files to be downloaded and played are downloaded to the advertisement playing device at a higher speed and played in time.

The invention discloses a video pushing implementation method, system and device. The method comprises the first step of receiving a video pushing notification message sent by a video server and carrying the emergency video ID, the second step of entering a video playing page when it is judged that the video pushed by the video server is an emergency video which is entered abnormally according to the video pushing notification message, and the third step of requesting corresponding video resource description information from the video server according to the video ID contained in the video pushing notification message, and playing the emergency video according to the requested video resource description information. By means of the method, pushing of the emergency video can be implemented, and it is guaranteed that the emergency video can be played quickly in time.

The invention relates to the technical field of broadcast communication, in particular to an intelligent emergency broadcast system. The intelligent emergency broadcast system comprises a broadcast controller, transmission equipment and intelligent receiving terminals. The broadcast controller comprises emergency broadcast sound sources, normal broadcast sound sources, a sound source selector, a control management platform, a broadcast frequency modulation modulator and an encoder. Under an emergency situation, the broadcast controller controls the sound source selector to select the emergency sound sources through the control management platform according to the region division condition and according to the broadcast commands of the broadcast frequency modulation modulator and the encoder corresponding to emergency broadcasts. The selected emergency broadcast sound sources are transmitted to the corresponding intelligent receiving terminals through the transmission equipment to be broadcasted. By means of the intelligent emergency broadcast system, the technical problem that in the prior art, for regional difference, the emergency broadcast information cannot be popularized is solved, and the technical effect that the emergency broadcast information can be received through various receiving terminals in all regions is achieved.

The invention relates to the technical field of emergency broadcast, in particular to an emergency broadcast pad broadcast scene switching method and system. The invention is applied to an emergency broadcast underlay scene switching system, and the system comprises an emergency decoding module; the method comprises the following steps: monitoring and receiving emergency data sent by a superior platform; analyzing the emergency data according to an emergency protocol to obtain emergency information required by underlay; decoding the emergency information through an emergency decoding module toobtain an emergency information level and emergency audio and video data; and according to the emergency information level, realizing combined coding of the emergency audio and video data and the current output audio and video data, and realizing pad broadcast output of the emergency broadcast on the terminal. The invention is simple to use, does not need to formulate a pad broadcast program in advance, can achieve audio and video data processing through analysis, is flexible in switching of the pad broadcast scene, can flexibly switch the pad broadcast scene according to a superior instruction, namely an emergency information level, does not affect program playing of a receiver, and greatly improves the receiving experience of the receiver.

The invention provides an intelligent voice interaction interruption processing method, device and system, when a user needs to interrupt target voice played by a robot, interruption voice is sent to the robot, and at the moment, the robot responds to the interruption voice and determines a first timestamp corresponding to the played current voice. In order to ensure the playing integrity when the current voice stops playing, an interruptible timestamp is set in the current voice in advance to serve as a node for really interrupting the playing voice. After the robot determines the first timestamp, the robot needs to determine the corresponding interruptible timestamp, namely the second timestamp, according to the first timestamp, and in order to stop playing voice in time, the first interruptible timestamp after the first timestamp is selected as the second timestamp. Therefore, the current voice is continuously played to the second timestamp, so that the playing integrity of the voice can be ensured, the playing of the current voice can be stopped in time, and other requirements proposed by a user can be responded in time.

The invention discloses a streaming media file downloading method and device. The method comprises the following steps: determining a first downloading granularity when a fragment of a streaming media file needs to be downloaded, taking the first downloading granularity as the data volume requested to be downloaded for a single time, downloading fragment description data of the fragment; based on the fragment description data, constructing a data frame index table; determining a second downloading granularity, and downloading the content data frame indicated by the data frame index table by taking the second downloading granularity as the data volume requested to be downloaded for a single time. According to the method and the device, each segment of the streaming media file is split and downloaded according to a certain downloading granularity, so that the downloading and playing performance of the streaming media file can be improved.

The invention relates to a manufacturing method of a projection screen panel. The manufacturing method of the projection screen panel comprises the following steps that (1) polycarbonate, acrylic resin and organic silicon are uniformly mixed, dried for six hours and stirred at the high speed, so that a macromolecule raw material is obtained; (2) solvent red, carbon black, phthalo blue, a dispersing agent, an antioxidant and polycarbonate are taken and stirred at the low speed, the heating is conducted to enable the temperature to range from 260 DEG C to 280 DEG C, and pelletization is conducted, so that colored nano particles are obtained; and (3) the macromolecule raw material obtained in the step (1) and the colored nano particles obtained in the step (2) are taken, stirred and added toan extruder set, and the transmission screen panel is obtained through extrusion, specifically, the thickness of the transmission screen panel ranges from 1.5mm to 2mm.
