Method and terminal for receiving and transmitting mobile digital broadcast television signal

Abstract

The invention discloses a method for receiving and the transporting signals of digital mobile radio and television which includes china digital television terrestrial broadcast (DMB-TH) and china mobile digital multimedia broadcast used on a handheld device, and a DMB-TH terminal or a CMMB terminal which adopt the method. The method comprises the steps of receiving and transporting, wherein the receiving step is characterized in that DMB-TH or CMMB signals are not only received, but also transported to a MPEG-2TS transport stream including a video steam, a video stream, or other data objects, or a data stream including a video steam, a video stream, or other data objects, the transporting step is characterized in that the feedback MPEG-2TS transport stream including the video stream, the video stream, or other objects, or the data stream including the video stream, the video stream, or other objects, are converted into a format suitable for being transported to an external device and transported to the external device. The DMB-TH terminal or the CMMB terminal comprises an independent power supply, a receiving sub-module, and a communication sub-module, wherein, the communication is a 204 GHz Bluetooth sub-module, so that the adoption of the Bluetooth sub-module enables various information data to be converted by the Bluetooth standard and sent through a wireless device.

Description

technical field [0001] The present invention relates to a kind of technical field of signal reception and transmission, especially for receiving DMB-TH (China Digital TV Terrestrial Broadcasting Transmission System Standard, used for terrestrial digital TV broadcasting of hand-held and portable devices) signals or CMMB (ChinaMobile Multimedia Broadcasting, A method for receiving and transmitting a mobile digital broadcast TV signal of China Mobile (DMB) signal and decoding and outputting video / audio / multimedia data / IP data packets or system information and a terminal used. The terminal can use various existing communication technologies, such as Bluetooth or Wi-Fi communication technologies, to communicate with other devices using Bluetooth or Wi-Fi. Background technique [0002] DMB-T technology is a terrestrial digital TV transmission solution proposed by Tsinghua University and Beijing Lingxun Huaye Technology Co., Ltd., called Terrestrial Digital Multimedia Broadcasting ...

AI Technical Summary

Problems solved by technology

[0014] However, currently, mobile phones or other handheld devices support China Digital TV Terrestrial Broadcasting (DMB-TH) or China Mobile Digital Multimedia Broadcasting (CMMB) Both solutions have several common technical shortcomings

First, the received signal is susceptible to

When the use environment is inside a building, the received signal may be relatively poor. If a larger antenna is used, it will cause inconvenience to the use of handheld devices, especially mobile phones.

Second, the power consumption of handheld devices increases a lot

In handheld devices, especially mobile phones, power saving has always been the most important issue. For example, the power consumption of the tuner of the existing receiving module is relatively large, which reduces the battery life of handheld devices, especially mobile phones.

Third, when the other designs remain unchanged, the DMB-TH receiving module or CMMB receiving module is added. For mobile phones or other handheld device products that directly integrate DMB-TH or CMMB receiving modules into the device, the size of the product will increase, for DMB-TH or CMMB receiving module products using USB, SDIO or CF interface, because the existing DMB-TH receiving module or CMMB receiving module is not small enough, thus exceeding the mobile phone or handheld device products Normal profile, both of which are disadvantages for hand-held products, especially mobile phones, which focus on product size

This is an unfavorable factor for the promotion of China Digital TV Terrestrial Broadcasting (DMB-TH) or China Mobile Digital Multimedia Broadcasting (CMMB)

It also increases the burden on consumers
