Example 2
With the continuous improvement of video service demands, VR/AR is widely applied, and current mobile communication network load cannot bear 4K or even future 8K video on demand live services, especially centralized on demand requests of a large number of users for hot content. The popular on-demand hot content obeys ziff distribution. The present embodiment is directed to providing high definition VR video services. The video content and the control information with high interactivity in the VR/AR video service are realized through a cellular network, so that the low-delay high-instantaneity service requirement is met; video rendering service contents such as background and local rendering contents which need large bandwidth transmission in video are mainly considered to realize efficient distribution of the large bandwidth video rendering service contents through a digital broadcasting system.

Fig. 3 is a schematic diagram of a transmission method according to an embodiment of the invention.
The user terminal calculates the service content requested by the uplink user on the cellular network through the MEC server, the MEC server sends the service result to the terrestrial digital broadcasting system, the terrestrial digital broadcasting system sends the service result to the user terminal through a broadcasting link, and the user terminal receives the downlink broadcasting signal through adding a broadcasting antenna module. The MEC server is arranged in the edge network, has computing capability, and can provide corresponding computing services and video cache services based on user requests, wherein the computing services comprise high-definition video rendering, application acceleration and the like. The MEC server has a caching capability with a user request queue. Meanwhile, the MEC server has computing capability, and the user requests video to be computed and rendered, so that user experience is improved.
The MEC server sets up a user request queue, discards overtime user requests in each request time slot, and adjusts the execution sequence of the user requests through a dynamic programming algorithm such as a random network optimization algorithm, and specifically comprises the step that the MEC server adjusts the execution sequence of the user requests according to service quality indexes in a preset update time slot, wherein the indexes related to the service quality comprise at least one of the following: network delay, task discard rate or calculation power consumption; or the MEC server performs hot ranking on the user requests in a preset updating time slot, wherein the hot ranking comprises the steps of counting the user requests, identifying the user requests with the same content, and ranking the user requests with the same content from high to low to obtain an adjusted user request execution sequence; wherein the update time slot comprises a time interval of an MEC server update queue.
