Problems solved by technology

[0002] At present, mobile phones are widely used. With the development of mobile digital TV networks, there are also a small number of mobile phones with mobile digital TV functions, but the cost is high and the power consumption is large. The system architecture is shown in Figure 1.
Because digital mobile phone TV requires a lot of decoding work, it is necessary to configure a dedicated decoding chip for the TV module, and the decoded image data needs to be processed by the baseband part of the mobile phone and displayed on the LCD in real time, so not only the cost is high, but also the power consumption is high.

Embodiment Construction

[0013] As shown in Figure 2, in the specific implementation, according to the mobile digital TV transmission frequency that needs to be realized, select the TV antenna that matches the L-band to realize the perfect reception of wireless signals; The TV radio frequency tuner and the demodulator of TDMB are connected in the way shown in Figure 2. The mobile phone module is connected to the radio frequency module of the mobile phone according to the usual mobile phone connection method. The radio frequency module is connected to the mobile phone baseband and controlled by the mobile phone baseband. The mobile phone baseband is connected to the multimedia processor through a parallel bus, while the LCD is directly connected to the multimedia processor.

[0014] When the mobile phone is turned on, it starts from the baseband first, then initializes the multimedia processor, and transmits the firmware (Firmware) of the multimedia processor to the RAM of the multimedia processor thro...

Abstract

The invention provides a mobile phone which is provided with a function of receiving a mobile digital television. The invention is mainly characterized in that the mobile phone utilizes a self-contained multimedia processor that is provided with a common high and mid grade mobile phone, thus not only achieving the multimedia function of the mobile phone, but also having decryption and decoding function of the television while the digital television plays, thereby greatly reducing the cost of achieving mobile digital television on the mobile phone, effectively decreasing the power consumption when the digital television plays and having very good practical value.

Description

technical field [0001] The invention relates to a mobile digital TV and a mobile phone, in particular to a combined mobile phone with mobile digital TV functions. Background technique [0002] At present, mobile phones are widely used. With the development of mobile digital TV networks, there are also a small number of mobile phones with mobile digital TV functions, but the cost is high and the power consumption is high. The system architecture is shown in Figure 1. Because digital mobile phone TV requires a lot of decoding work, it is necessary to configure a dedicated decoding chip for the TV module, and the decoded image data needs to be processed by the baseband part of the mobile phone and displayed on the LCD in real time, so not only the cost is high, but also the power consumption is high. . Contents of the invention [0003] In order to overcome the above-mentioned shortcomings of the prior art, the present invention provides a method for realizing a mobile phone...
