The invention discloses a method for mobile phone to play real-time monitoring video. The method comprises the following steps: front video monitor equipment collects the images of monitoring place and converts the collected images to data signal; a mobile phone client send verification request to the front video monitoring equipment through wireless network and the front video monitoring equipment receives the verification request and carries out verification, wherein if the verification is succeed, the front video monitoring equipment sends video data, and if the verification is not succeed, the front video monitoring equipment gives no processing; the mobile phone client registers callback function and receives video data; the mobile phone client detects and analyzes the received videodata to obtain I frame information; according to the obtained I frame information a jitter buffer area is created to collect and store video data with frame as unit, and when the data bulk reaches jitter buffer lower limit threshold values video data is sent to a decoding module for processing; finally the video data after decoding is played on the mobile phone. The method in the invention has the advantages of fluency, good instantaneity, high sharpness and simple network environment.

The invention discloses a reversing radar camera shooting device and a camera shooting system based on same. The reversing radar camera shooting device comprises a wire, a plug, and a housing. The housing contains a lens support, multiple terminals fixed in a rear housing, and a PCB connector electrically connected with the wire. A lens and multiple copper shafts extending towards the rear housing are installed in the lens support. Each terminal is equipped with a contact portion in contact with the copper shaft. Each contact portion comprises a central circular ring and contact arms which are uniformly distributed on the periphery of the circular ring and is tangent to the arc of the outer circle of the circular ring. Each circular ring is provided with a gap through which a copper pin passes. After each copper pin passes through the corresponding gap, an abutted portion is fixed in a space defined by the multiple contact arms and each contact arm adheres to the abutted portion. According to the reversing radar camera shooting device, the contact area between the copper shafts and the terminals is enlarged and tangency design enables no gaps between the copper shafts and the terminals so that good electric contact is guaranteed between the copper shafts and the terminals. As a result, a phenomenon of unclear display or no display is prevented when a vehicle reverses.

A streaming media file processing method and a live streaming system are provided. The method includes slicing a streaming media file into slices according to a preset time unit; creating a playing sequence number for each slice based on time data, where the playing sequence number is used to determine an order of playing back the slices; and storing the slices and the playing sequence numbers of the slices separately and establishing a mapping relationship between the slices and the corresponding playing sequence numbers. The present disclosure slices the streaming media file based on the preset time unit, and creates the playing sequence number for each slice based on time data, and selects and processes the slice file corresponding to the playing sequence number based on the time information, which facilities the subsequent operation to the slice file. In addition, the present disclosure also provides a live streaming system.

The invention provides a long strip LED screen. The screen comprises a control card and multiple unit plates. The unit plates comprise multiple first unit plates and multiple second unit plates. The first unit plates are connected to the control card in a first cascading manner so as to form at least one string of first unit plates. The second unit plates are connected to the control card in a second cascading manner so as to form at least one string of second unit plates. The cascading direction of the first cascading manner is opposite to that of the second cascading manner. The at least one string of first unit plates and the at least one string of second unit plates are spliced together into a long strip LED screen body. Thus, the on-load length of the control card of the long strip LED screen can be increased.
