Embodiment Construction

[0044] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0045] Such as figure 1 As shown, the logical channel configuration method used in the CMMB system in this implementation includes the following steps:

[0046] Step 1: Reserve K consecutive time slots starting from the initial time slot N in the channel transmission frame as a dynamic configuration area.

[0047] In order to realize the automatic configuration of the service logic channel, it is first necessary to reserve a time slot for the automatic configuration from the channel transmission frame. Such as figure 2As shown, the channel transmission frame of CMMB consists of 40 time slots (TS0–TS39), of which time slot 0 is used as a control channel to transmit control information, and time slot 1 to time slot...

Abstract

The invention relates to a logic channel configure method for a China mobile multimedia broadcasting (CMMB) system. The method comprises the following steps of: 1. reserving continuous time slots in channel transmission frames to serve as dynamic configure regions; 2. arranging a service auto-configure server (SACS) for each dynamic configure region; 3. setting parameters needing to be stored on the SACSs; and 4. starting the SACSs to begin implementing service events. The method has the following beneficial effects: auto configure of the service logic channels is realized by arranging one SACS; the configure process of the service logic channels is simplified; short-time service support is facilitated; the capability of automatically switching services at fixed time is provided; and the compatibility with the existing configure modes is retained.

Description

technical field [0001] The invention relates to the technical field of digital information transmission, in particular to a method for China Mobile multimedia broadcasting and capable of automatically configuring logical channels for services. Background technique [0002] China Mobile Multimedia Broadcasting (CMMB) is the first digital broadcasting system independently developed in China for various mobile terminals such as mobile phones, PDAs, MP3, MP4, digital cameras, and notebook computers. The system utilizes satellite and terrestrial U-band broadcasting to achieve seamless coverage throughout the entire process, supports nationwide roaming and unified operations, and provides various types of multimedia services such as digital broadcasting and television, emergency broadcasting services, and comprehensive information push. Individuals provide information services, which have significant commercial value and social benefits. [0003] In order to support the transmiss...
