Next, in the foregoing embodiment of the present application, before the step S12 determines whether each signal source "abaacabb" to be displayed belongs to the selected signal source, the user at the user equipment end selects the signal source "C" from each displayed signal source "abaacabb" by using a mouse or a shortcut keyboard, and records the selected signal source "C" at the subsequent user equipment end, so that the locally selected signal source and the identification information corresponding to the locally selected signal source are "signal source C and the identification information corresponding to the signal source C are MAC 3"; and then, the step S12 respectively judges whether each to-be-displayed signal source "abaacabb" belongs to the selected signal source according to the identification information corresponding to each to-be-displayed signal source "abaacabb" being MAC1, MAC2, MAC1, MAC1, MAC2, MAC1, MAC3, MAC2 and the identification information "MAC 3" corresponding to the locally selected signal source "C", so as to obtain the signal source "C" to be displayed belonging to the selected signal source, thereby determining the selected to-be-displayed signal source in all the to-be-displayed signal sources based on the locally selected signal source.
Further, before displaying the frame data corresponding to the selected signal source to be displayed in step S13, the method further includes: and locally storing the frame data corresponding to the selected signal source to be displayed. For example, after all the data information corresponding to the selected signal source "C" to be displayed is decoded, the decoded frame data corresponding to the selected signal source "C" to be displayed is stored locally, so that when the frame data corresponding to the selected signal source "C" to be displayed needs to be displayed subsequently, the frame data corresponding to the selected signal source "C" to be displayed can be read and displayed in real time, and the timeliness of frame data display is further improved.
Further, the displaying frame data corresponding to the selected signal source to be displayed in step S12 includes: and displaying frame data corresponding to the selected signal source to be displayed based on the original display frame rate.

For example, after the data information corresponding to all the unselected signal sources to be displayed "abaabaababab" is screened and decoded, the screening frame data corresponding to each unselected signal source to be displayed "ababab" obtained after decoding is stored locally, so that when the screening frame data corresponding to any one signal source to be displayed in each unselected signal source to be displayed "ababab" needs to be displayed subsequently, the screening frame data corresponding to the selected signal source to be displayed (for example, the unselected signal source to be displayed "a" and the identification information MAC1 corresponding thereto) can be read and displayed in real time, and the timeliness of displaying the screening frame data is further improved.
Further, the step S14 of filtering and decoding the data information of the unselected signal source to be displayed to obtain filtered frame data corresponding to the unselected signal source to be displayed includes:

and decoding the screened data information to obtain screened frame data corresponding to the unselected signal source to be displayed.
Then, in the above embodiment of the present application, after each unselected signal source to be displayed "ababab" is determined, first, data information corresponding to the unselected signal source to be displayed (for example, signal source to be displayed "a") is screened to obtain data information including key frame data of the unselected signal source to be displayed "a"), then, the data information including key frame data of the unselected signal source to be displayed "a" is decoded to obtain screened frame data of the unselected signal source to be displayed "a", where the screened frame data includes key frame data for identifying the unselected signal source to be displayed "a" to decode the unselected signal source to display the screened frame data of the unselected signal source to be displayed in real time, so as to ensure real-time display of frame data corresponding to the selected signal source to be displayed, and the screening frame data corresponding to the unselected signal sources to be displayed can be displayed in real time, so that the display delay or delay of each signal source to be displayed is avoided.

For example, if the number of the acquired to-be-displayed signal sources is 100, determining that the display frame rate of the unselected to-be-displayed signal source is 10 frames/s, or for example, if the number of the acquired to-be-displayed signal sources is 60, determining that the display frame rate of the unselected to-be-displayed signal source is 20 frames/s; for example, if the number of the acquired signal sources to be displayed is 20, determining that the display frame rate of the unselected signal source to be displayed is 25 frames/s, and dynamically determining the screening display frame rate of the unselected signal source to be displayed based on the number of the acquired signal sources to be displayed so as to ensure that screening frame data corresponding to each signal source to be displayed, which needs to be displayed, can be displayed in real time; then, based on the dynamically determined screening display frame rate, respectively screening data information corresponding to each unselected signal source to be displayed, so that the screened data information includes key frame data of the unselected signal source to be displayed.
Further, the displaying the filtering frame data corresponding to the unselected signal source to be displayed in step S14 includes: and displaying the screening frame data corresponding to the unselected signal source to be displayed based on the screening display frame rate. For example, if the screening display frame rate dynamically determined based on the number of all the acquired to-be-displayed signal sources is 20 frames/s, the screening frame data corresponding to the selected to-be-displayed signal source is displayed according to the screening display frame rate of 20 frames/s, so that the screening frame data corresponding to the unselected to-be-displayed signal source "C" can be displayed smoothly in real time while the frame data corresponding to the unselected to-be-displayed signal source "abaabaababab" is displayed according to the original display frame rate of 30 frames/s.
Further, after the step S14 of screening the data information of the unselected signal source to be displayed, the method further includes: and obtaining the common frame data information corresponding to the unselected signal source to be displayed, and discarding the common frame data information. For example, in order to ensure real-time display of frame data corresponding to the selected signal source to be displayed and filtered frame data corresponding to the unselected signal source to be displayed, after the data information of the unselected signal source to be displayed is filtered in step S14, common frame data information corresponding to each unselected signal source to be displayed is obtained, and the obtained common frame data information is discarded, so as to reduce consumption of memory resources and display frame rate in the real-time display process, thereby ensuring real-time performance and timeliness of display of frame data corresponding to the selected signal source to be displayed and filtered frame data corresponding to the unselected signal source to be displayed.
