Description

technical field [0001] The invention relates to the technical field of computer and communication, in particular to a method, device and remote controller for transmitting multimedia resources. Background technique [0002] With the development of network and computer technology, multimedia resources on the network are becoming more and more abundant, and users can choose multimedia resources for entertainment and learning according to their own preferences. [0003] At present, after the multimedia resource server receives the request for obtaining multimedia resources sent by the user client, it determines whether to send the multimedia resource requested by the user according to the authority of the logged-in user in the user client. For example, the multimedia resource server determines whether to send the multimedia resource requested by the user. Charged multimedia resources are paid to determine whether the user has the right to obtain the multimedia resources. When t...
