Embodiment Construction

[0026] The main design of the present invention is to demodulate the TV program data through the radio frequency chip to obtain the baseband digital signal, and then directly transmit the original baseband digital signal to the computer through the communication port of the mobile phone terminal without any processing. The hardware and software functions perform protocol processing on the digital baseband signal, and finally send the multimedia data stream to the multimedia player software for playback.

[0027] The steps of the embodiment of the present invention are as follows:

[0028] Step 1: the mobile terminal receives the wireless multimedia program signal broadcast by the mobile multimedia base station;

[0029] Step 2: The mobile multimedia radio frequency chip of the mobile terminal demodulates the wireless multimedia program signal to obtain a digital baseband signal;

[0030] Step 3: the mobile multimedia radio frequency chip of the mobile terminal transmits the d...

Abstract

The method comprises: mobile terminal receives the radio multimedia program signals broadcasted from the multimedia base station, and demodulates the radio multimedia signals to get digital baseband signals; the mobile terminal transmits the digital radio baseband signals to the computer through communication port; the protocol process module at computer side decodes the original digital baseband signals, and after error correction, uses framing protocol to translate the digital baseband signals into multimedia data stream. The feature of the invention is: not depending on any dedicated chip.

Description

technical field [0001] The invention relates to mobile multimedia technology, in particular to a processing method for baseband digital signals of mobile multimedia programs. Background technique [0002] With the rapid development of mobile multimedia broadcasting technology (that is, mobile phone TV), more and more operators have launched mobile multimedia broadcasting services, providing broadcasting and TV programs and information services for various mobile portable terminals. Although there are still some standard disputes, mobile multimedia broadcasting technology is slowly coming to consumers. [0003] At present, the working mode of commercial mobile phone TV in the market is as follows: the mobile terminal receives the multimedia program broadcast by the base station, demodulates it through the mobile multimedia radio frequency chip, and then performs protocol processing through the mobile multimedia baseband processing chip, and then sends the multimedia data stre...
