Embodiment Construction

[0051] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0052] The multimedia communication method provided by the present invention includes: the transmitting end maps data from different information sources to different time slices, multiplexes all the time slices to form a super frame, and in the formed super frame, carries the data for each time slice The data added to the control signaling, and then the superframe added to the control signaling is modulated and then transmitted; the receiving end demodulates the superframe from the transmitting end, and directly analyzes the control signaling contained in the time slice obtained from the processing , and determine the time slice to be received according to the analyzed control signaling.

[0053] The transmitting end multimedia communication system provided by the present invention at least includes a signal source adapter, a channel encoder,...

Abstract

The invention also discloses multimedia communication system (MCS) at transmitting end, and MCS at receiving end. Both of the method and system support following procedures: the transmitting end maps data from different sources to different time slices; multiplexing time slices to form super frame; adding control signaling to data carried by each time slice in formed super frame; transmitting out modulated super frame with control signaling being added. Demodulating super frame from the transmitting end, the receiving end can obtain control signaling contained in time slice directly after parsing process. Both of the method and system can shorten time of identifying own needed information source by multimedia data receiving end effectively. The invention raises users' satisfaction degree.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a multimedia communication method and system. Background technique [0002] With the development of communication technology, multimedia communication is becoming more and more popular. Users can use user equipment (UE) to communicate with the multimedia communication system to receive more and more multimedia services from the multimedia communication system, such as: including mobile digital TV Business including mobile video broadcasting services, etc. [0003] For the above-mentioned multimedia services such as mobile digital TV services, when the multimedia communication system communicates with the UE, as the transmitter of multimedia data, the multimedia communication system adds corresponding signaling content to multimedia data from different sources, and then transmits The multimedia data added to the signaling content is processed by multiplexing, scrambling, cod...
