Abstract

A terminal which can access to the historical channel is applied in a mobile multimedia broadcast system. The terminal comprises a service processing module, a channel information recording module, a frequency channel information reading module and a non-volatile access memory. The method for accessing the historical channel of the mobile multimedia broadcast comprises the following procedures: when a terminal selects to access a mobile broadcast channel, storing the information of the frequency point which the current channel is in and time slice information in a non-volatile access memory; and when the terminal accesses the mobile multimedia broadcast service and if the non-volatile access memory is stored with information of the frequency point which the current channel is in and time slice information of the historical channel stored in last exit, accessing the historical channel according to the frequency point information and the time slice information. The adoption of the invention facilitates the terminal user and increases the using convenience of the terminal, and the invention has strong practicability in the field of the mobile multimedia broadcast.

Description

technical field [0001] The invention relates to mobile multimedia services, in particular to a terminal capable of accessing historical channels and a method for accessing historical channels. Background technique [0002] In recent years, digital mobile multimedia broadcasting technology and standards have developed rapidly, such as DVB-H (Digital Video Broadcast Handheld, digital video broadcast handheld reception), MediaFLO (Media Forward Link Only, media single forward link) and CMMB (China MobileMultimedia Broadcasting, China Mobile Multimedia Broadcasting), etc. [0003] CMMB technology uses a time-division method to send multimedia broadcast services. The broadcast channel frame lasts for 1 second and consists of 40 time slots of 25 milliseconds. One or more time slots can carry a set of data encapsulated in a broadcast multiplexing frame. In the multiplexing frame structure of mobile multimedia broadcasting, such as figure 1 As shown, the multiplexed frame is divid...
