Data transmission method, server and terminal thereof

Abstract

The invention relates to a data transmission method, a server and a terminal thereof. In the prior art, by using an HFC scheme, an uplink bandwidth is limited so that bidirectional control of a transport stream under a unidirectional network is not flexible; and by using an IP scheme, highest concurrent pressure of a front end system exists. By using the method, the server and the terminal of the invention, the above problems are solved. The method comprises the following steps of after the server receives a request control instruction sent by the terminal, analyzing control information contained by the request control instruction, wherein the control information includes a corresponding first identification used for expressing a control information type; according to the first identification corresponding to each piece of control information and a content in a corresponding database, determining response information corresponding to a content of the control information corresponding to the first identification; and according to a packaging mode which is appointed in advance with the terminal, packaging all the determined response information into a data packet and sending the data packet to the terminal through a network.

Description

technical field [0001] The present invention relates to the field of data transmission, in particular to a data transmission method, server and terminal. Background technique [0002] Among the current mainstream video service solutions, traditional radio and television operators (such as Gehua Cable) provide VOD (Video On Demand) video services based on the HFC (Hybrid Fiber-Coaxial, that is, hybrid fiber-coaxial cable network) network, referred to as the HFC solution; Internet video Service providers (such as Youku) provide Internet video services based on IP bidirectional networks, referred to as IP solutions. [0003] The radio frequency network in the HFC solution has the natural advantages of high downlink bandwidth (38M bandwidth for a single frequency point, multiple frequency points) and large transmission capacity. However, due to its limited uplink bandwidth, it usually limits the development of services that require high uplink communication. , which in turn lea...
