    摘要： A processing method and device for media transmission right is described. After a control point in a multi-party communication system receives a media transmission right application from a user, the control point performs judgment according to media transmission right types carried by the application and media transmission right attributes preset by the control point, and obtains an authorization result. According to the authorization result, the control point transmits a corresponding permit media transmission right response of a permitted media transmission right type to the user, and transmits a corresponding accept response of the permitted media transmission right type to other users in the group of the user, and the user transmits corresponding media stream data of the permitted media transmission right type to the other users in the group of the user; and the control point transmits a corresponding reject media transmission right response of a rejected media transmission right type to the user. The invention realizes the control of a number of media transmission rights for a request for the multi-type media transmission rights provided by multimedia service for multi-party communication.

    摘要： Embodiments of this application provide a modulation method and apparatus. The method includes: receiving a code word sequence, where each code word includes N bits, and the code word sequence includes at least a first code word; mapping the code word sequence into M sequences, where each sequence includes N/M bits from the first code word; mapping the M sequences into a symbol sequence, where each symbol is corresponding to M bits, the M bits are respectively from the M sequences, first bits corresponding to N/M first-type symbols are from the first code word, and second bits corresponding to N/M second-type symbols are from the first code word. As a result, a first bit corresponding to the second-type symbol is definitely from another code word different from the first code word. A bit in the second-type symbol and from the another code word may be demodulated by using information about the first code word, so that the bit in the second-type symbol and from the another code word can be demodulated more accurately, thereby lowering a signal-to-noise ratio requirement during higher order modulation.
