Problems solved by technology

[0008] 1. The portable players mentioned above all have certain video playback capabilities, but because the screen is too small, the display effect cannot meet the user's needs for comfort and shock;
[0009] 2. Mobile video glasses in the prior art do not have the capability of wireless reception. Watching DVD and other multimedia video programs requires a wired connection, which is inconvenient for mobile video customers to watch digital video programs.

Embodiment Construction

[0025] Further details will be given below in conjunction with the preferred embodiments shown in the accompanying drawings.

[0026] A mobile video glasses integrated with a CMMB receiving module of the present invention includes a video glasses display module 101, especially, also includes a CMMB receiving module 200 embedded in the structure of the mobile video glasses, and the receiving module 200 includes a built-in Application processor 202, CMMB demodulator 203, CMMB tuner 204 and antenna 205 of MPEG-2 / MPEG-4 decoding chip.

[0027] like figure 1 As shown, the antenna 205 receives the analog signal modulated on the high-frequency carrier, and transmits the high-frequency carrier modulated by the analog signal to the CMMB tuner 204 for processing; the tuner 204 outputs the zero-IF I / Q signal to The CMMB demodulator 203 performs analog / digital conversion, then performs OFDM demodulation, LDPC parity check and RS error correction, and then obtains the MPEG-4 TS data strea...

Abstract

The invention relates to a pair of mobile video glasses integrated with a CMMB receiving module, comprising a video glass display module (101) and the CMMB receiving module (200) embedded in the mobile video glasses, wherein the receiving module (200) also comprises an application processor (202), a CMMB demodulator (203), a CMMB tuner (204) and an antenna (205), and an MPEG-2 / MPEG-4 decoding chip is arranged in the application processor (202). The antenna (205) receives an analog signal modulated on a high-frequency carrier wave and sends the analog signal to the CMMB tuner (204) so as to be processed; a zero intermediate frequency I / Q signal is outputted to the CMMB demodulator (203), and MPEG-4TS data flow is finally obtained; after filtering the signal of the obtained TS data flow, the application processor (202) decodes the signal of the TS data flow; the video signal obtained by decoding is outputted to the video glass display module (101) so as to be displayed. The wireless receiving performance is improved, and convenience is provided for the mobile video customer to look at the digital video signal by using the mobile video glasses.

Description

technical field [0001] The present invention relates to an optical instrument, in particular to an instrument for producing stereo or other three-dimensional effects, in particular to a mobile video glasses integrated with a CMMB receiving module. Background technique [0002] With the rapid development of technology, portable players are popularized rapidly, and their related accessories are constantly being updated and expanded. Although portable players have certain video playback capabilities, the display effect is far from satisfying users' desire for comfort due to their small screens. Although ordinary video glasses can enable users to obtain clear and shocking video effects, But because it must be wired to the audio / video signal source, it brings great inconvenience to the user. [0003] CMMB, that is, "China Mobile Multimedia Broadcasting" is the abbreviation of the industry standard of "China Mobile Multimedia Broadcasting System". Using this industry standard and...
