Abstract: The present disclosure provides a synchronous display method of a spliced screen, a display system, an electronic device and a computer readable medium. The spliced screen includes display screens spliced together, and the display method is based on wireless communication and includes: sending control information to the spliced screen for N times at intervals so as to control the display screens to display simultaneously, where N is not less than 2 and is an integer, the control information sent for previous N?1 times includes first information and second information, the control information sent for an Nth time at least includes the second information, the first information is configured for controlling the display screen receiving the control information to turn off a receiving component of the display screen, the second information is configured for controlling the display screen receiving the control information to display after a preset time duration.

Abstract: The present disclosure provides a display control method of a spliced screen including a plurality of sub-display screens, including: sending a display control signal to each sub-display screen in a wireless sending manner according to a time code signal; receiving, by each sub-display screen, the display control signal in a wired receiving manner, and reporting status information of each sub-display screen to the display controller; and controlling, by the display controller, displaying of each sub-display screen according to the status information of each sub-display screen, where the time code signal indicates a current time point; the display control signal is configured for controlling the sub-display screen to perform corresponding display processing on display content stored, so that the sub-display screens display a target display content together. The present disclosure further provides a display control device, a display system, an electronic device, and a computer readable storage medium.

Abstract: A data processing method includes: acquiring first image data including pixel values that are arranged consecutively and divided into data blocks, each data block occupying one byte and including at least one pixel value; and compressing, according to at least one compression parameter, at least one data set to be compressed in the first image data into a corresponding compression unit, so as to obtain second image data including the compression unit. The data set to be compressed includes at least two data groups that are arranged consecutively and identical. Each data group includes a single data block or at least two data blocks arranged consecutively. The at least one compression parameter includes a first length configured to represent the number of at least one data block in a data group. The compression unit includes one data group and a second length configured to represent the number of data groups.

Abstract: A data transmission method and device, electronic apparatus and a storage medium provided by the disclosure are applied to the technical field of Internet of Things (IoT). The method comprises: receiving first underlying data sent by an IoT terminal; extracting part of data from the first underlying data as second underlying data according to parameter position information; converting the second underlying data into a target data format according to a format requirement corresponding to the parameter position information, so as to obtain third underlying data; and sending the third underlying data to an IoT server.

Abstract: Provided is a transmitting antenna system, which includes an omnidirectional antenna and a phased array antenna, wherein a phased array antenna includes a plurality of antenna arrays which are disposed on the circumference with an omnidirectional antenna as the center, and the interval between any two adjacent antenna arrays is the same. The present disclosure also provides a receiving antenna system and a communication device.
