Problems solved by technology
Update via mobile network refers to obtaining and updating the video source through the shore-based mobile network when the ship is docked. This method cannot guarantee the freshness of the video.
When the ship is far away from the coast, due to the unstable communication quality at sea, this method cannot properly obtain and update the video source
Most of the existing technologies use mobile hard disks to update the video source, the cost is too high, and at the same time, the update cycle of the video source is long, and there are also great potential safety hazards

Embodiment Construction
[0048] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0049] Such as Figure 1-3 As shown, a sea area video source acquisition method based on the communication antenna in motion, the video source is acquired through the following steps:
[0050] Step 1. The user ship requests the video source from the currently connected base station through the communication-in-motion antenna;
[0051] Step 2. The base station scans the local server and other units connected to it, and judges the video source. The judgment rule ...

The present invention specifically relates to a method for acquiring video sources in sea areas based on communication-in-motion antennas, which belongs to the field of communication technology. When a user needs to update the acquired video sources, the base station scans the local server and other connected units, and judges whether there are For the required video source, by calculating the transmission coefficient of the video source, the optimal video transmission base station is selected according to the judgment conditions to communicate and obtain the update of the video source. According to the characteristics of broadband information coverage in the sea area, the mobile communication antenna based on the user terminal is used. The video source address is reasonably selected and switched, so that the ship can use the near-shore base station and the far-sea ship-borne base station to reasonably switch to complete the acquisition and update of the video source during driving, effectively maintaining the freshness of the video source of the video-on-demand system.
Description
technical field [0001] The present invention relates to the communication field, in particular to a sea area video source acquisition method based on a communication-in-motion antenna. Background technique [0002] With the rapid development of marine industries such as marine ranching and marine tourism, the demand for information services such as massive data transmission and online broadband entertainment has become increasingly prominent. Sea area video on demand system is to provide video on demand service for sea users. At present, the video source acquisition and update methods of the sea area video-on-demand system are mainly through mobile network update and mobile hard disk update, but these two methods have obvious disadvantages. Update via mobile network refers to obtaining and updating the video source through the shore-based mobile network when the ship is docked. This method cannot guarantee the freshness of the video. When the ship is far away from the coas...
