Abstract

The invention discloses a CMMB player and a playing method, which have low independence on hardware and relatively high portability and flexibility. The CMMB player comprises a tuning control module, a CMMB source filter, a CMMB de-multiplexer and an output module, wherein the tuning control module is used for sending a tuning control command to the CMMB source filter; the CMMB source filter is used for controlling CMMB equipment to modulate frequencies according to the tuning control command of the tuning control module, receiving a multiplexed sub-frame which is sent by the CMMB equipment and outputting the multiplexed sub-frame to the CMMB de-multiplexer through an output PIN; the CMMB de-multiplexer is used for de-multiplexing and separating the received sub-frame and outputting the separated data to the output module through the output PIN; and the output module is used for decoding and displaying the data which is output by the CMMB de-multiplexer.

Description

technical field [0001] The invention relates to the field of mobile digital television, in particular to a CMMB (China Mobile Multimedia Broadcasting, China Mobile Multimedia Broadcasting) player and a playing method. Background technique [0002] CMMB (China Mobile Multimedia Broadcasting) is the industry standard of China Mobile Multimedia Broadcasting (commonly known as mobile TV). The receiving terminals include various mobile devices such as mobile phones, PDAs, MP3s, MP4s, digital cameras, and notebook computers. CMMB is a system for distributing multimedia information (including sound, image, text and other media information) by means of a broadcast network. [0003] The current CMMB player is usually integrated with the CMMB receiving device, and each device has a corresponding dedicated CMMB player, which is relatively highly dependent on the CMMB hardware receiving device, and has poor flexibility and portability. Contents of the invention [0004] The technica...
