Embodiment Construction

[0062] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0063] The multimedia communication method provided by the present invention needs to divide the program provided by the information source into at least one program group, and divide the subcarriers in the available entire bandwidth into at least one subcarrier group; and, the transmitting end uses the divided subcarriers The carrier group bears the program content contained in at least one program group and transmits the program content; the receiving end receives and analyzes the program content carried by the sub-carrier group of the transmitting end according to the signaling content that can indicate the program content. required program content.

[0064] The multimedia communication transmission device provided by the present invention includes a source adapter connected in pairs, a resource scheduling module, and a coding modulator; w...

Abstract

The invention discloses a multimedia communication method and system, and also a multimedia communication emitting device and multimedia communication receiving device, the method, system and device of the invention needs to plot the program provided by signal source into at least one program groups, the sub carriers in integral bandwidth is divided into at least one sub carrier groups; the emitting end can use content in sub carrier groups divided to carry at least one program groups, and emitting the content; and, the receiving end can receive and resolve the program content needed by itself carried in the sub carrier group. So, the method, system and device of the invention can increase the spectrum utilization ratio in multimedia communication, and number of program provided by signal source can be increased greatly, user contentment degree can be increased greatly.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a multimedia communication method, system, transmitting device, and receiving device. Background technique [0002] With the development of communication technology, multimedia communication is gradually becoming popular, and the multimedia communication system can realize more and more services, such as: mobile video broadcasting services including mobile digital TV services. Current mobile video broadcasting services are usually based on OFDM modulation, such as: DVB Handheld system (DVB-H), FLO system, etc. [0003] Specifically, the multimedia communication system includes a multimedia communication transmitting device as a multimedia data transmitting end, and also includes a multimedia communication receiving device as a multimedia data receiving end. For multimedia services such as mobile digital TV services, when the multimedia communication transmitting device comm...
