Embodiment Construction

[0012] The present invention will be further elaborated below in conjunction with the accompanying drawings.

[0013] Such as figure 1 As shown, the present invention provides a kind of mobile phone that supports RMVB video file playing, comprises DSP decoding chip 1 and BBIC2, wherein DSP decoding chip 1 communicates with BBIC2 by SPI, DSP decoding chip 1 is connected with BBIC2 as slave equipment, the highest of SPI The transmission rate is determined by BBIC2; the DSP decoding chip 1 and BBIC2 realize the driving of the display screen 3 of the mobile phone through the CCIR interface.

[0014] The 1-0 interface of DSP decoding chip 1 is connected with the 2-0 interface of BBIC2, and the 1-0 interface is responsible for the SPI_CS, SPI_CLK, SPI_DI, SPI_DO of DSP decoding chip 1, and the 2-0 interface is responsible for the SPI_CS, SPI_CLK, SPI_DI, The highest frequency of SPI_DO and SPI_CLK of BBIC2 can be set to 13MHz or 26MHz. In the preferred embodiment of the present inv...

Abstract

The invention discloses a mobile phone supporting RMVB video file playing, which comprises a digital signal processor (DSP) decoding chip and a base-band integrated circuit (BBIC), wherein the DSP decoding chip is communicated with the BBIC by a serial peripheral interface (SPI); and the DSP decoding chip and the BBIC drive a display screen by CCIR interfaces. A 1-0 interface of the DSP decoding chip is connected with a 2-0 interface of the BBIC, wherein the 1-0 interface and the 2-0 interface are in charge of CS, CLK, DI and DO of SPI communication; a 1-1 interface of the DSP decoding chip and a 4-1 interface of a Sensor are connected with a 2-1 interface of the BBIC together, and the 1-1 interface, the 4-1 interface and the 2-1 interface are the CCIR interfaces. A user can directly download an RMVB file in the mobile phone to play and does not need format conversion.

Description

technical field [0001] The invention relates to a mobile phone supporting RMVB video file playing. Background technique [0002] With the development of mobile communication, more and more users like to use mobile phones to watch video files. At present, common mobile phones basically support videos in MPEG-4 format, and the corresponding file name suffix is ​​".mp4", ".avi" or ".3gp", but MPEG-4 format video is not very rich due to its shortcomings such as low definition, and users often need to spend a long time to find their favorite MPEG-4 format video files. [0003] The video in RMVB format is favored by the majority of users for its high compression ratio, moderate file size, and clear video. At present, most video files on the Internet are in RMVB format, but RMVB format video cannot Play directly on common mobile phones. How to play the video in RMVB format downloaded to the computer on the mobile phone has become an urgent problem to be solved. In the existing so...
