Receiving and transmitting method for digital mobile broadcasting TV and terminal therefor

Abstract

This invention relates to a digital mobile broadcast TV including a digital multimedia broadcast or a receiving and transmitting method used in ground digital video broadcast of handheld devices and DMB or DVB-H terminal used by this method, in which, the receiving includes: receiving DMB or DVB-H signals and transferring them into information data signals containing mobile video flow media, DAB sound frame, service information and quick information channels or IP data packets containing video flow, audio flow, or other data objects, the transferring step includes: converting various information data signals of mobile video flow media, DAB sound frame and service information and the quick information channels or IP data packets containing video flow, audio flow or other data objects to a format suitable of being transmitted to peripheral equipments to be transmitted to them. DMB or DVB-H terminal includes independent power, receiving sub-modules and communication sub-modules of 2.4 GHz blue tooth sub-modules transforming various information data in terms of the blue tooth standard and transmitting them via radio devices.

Description

technical field [0001] The present invention relates to a technical field of signal reception and transmission, in particular to services for receiving DMB (digital multimedia broadcasting) signals or DVB-H (terrestrial digital video broadcasting for handheld devices) signals and decoding and outputting video / audio / multimedia data services A method for receiving and transmitting digital mobile broadcast television of data or IP data packets containing video content or / and other service content, 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] Digital Multimedia Broadcasting (DMB) is developed from Digital Audio Broadcasting (DAB). It adopts a technology completely different from AM and FM broadcasting. It has outstanding mobile reception capabilities and high-quality sound (CD quality), and can ...

AI Technical Summary

Problems solved by technology

[0012] however, current handsets or other handheld devices that support digital multimedia broadcasting networks or terrestrial digital video broadcasting for handheld devices 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

Third, when other designs remain unchanged, adding a DMB receiving module or DVB-H receiving module, for mobile phones or other handheld devices that directly integrate DMB or DVB-H receiving modules into the device, the size of the product It will increase. For products using SDIO or CF interface DMB receiving modules, because the existing DMB receiving modules or DVB-H receiving modules are not small enough to exceed the normal outline of mobile phones or handheld devices, these two cases It is a disadvantage for handheld products, especially mobile phones, that pay attention to product size

This is an unfavorable factor for the promotion of digital multimedia broadcasting systems or terrestrial digital video broadcasting for handheld devices

It also increases the burden on consumers
