The document of submitting to provisional application by reference above: ETSI EN 302304V 1.1.1 (2004-11), Digital Video Broadcasting (DVB); TransmissionSystem for Handheld Terminals (DVB-H) incorporates it into by reference at this.
Utilization such as cellular portable terminal receives and the ability that shows the TV signal is a feature in new and the evolution.At present, its use by DVB-H frequency band and associated electrical acceptor circuit realizes.In Europe/Asia, the DVB-H frequency band is 470-750.The frequency band that uses in the U.S. remains open.In ETSI, stipulated whole DVB-H system.
Normally, the DVB-H standard derives from DVB-T (land), and it allows lower power consumption, than low signal intensity and very fast moving, and the TV that is supported in the moving vehicle receives.DVB-H can carry the MPEG-4 video flowing of 11Mbit/sec, supports flowing to cellular 30-35TV of 150-400kbit/sec.In the U.S., expectation DVB-H will send on the 5-MHz of L-frequency band section.The L-band spectrum extends to 1790MHz from 1440MHz, thus if its adopted word, the frequency that then is used for U.S. DVB-H will be higher than the frequency band that is used for European DVB-H far away.
The record of TV broadcasting is the feature that at least some modern portable terminals of expectation can be supported.At present, nearly all portable terminal is all supported mass storage, and it is implemented by memory card interface, MMC/SD card reader.
Some typical operating positions that are used to write down TV broadcasting can comprise, but needn't be limited to: the TV record when watching same channel; TV record when watching another channel; TV record when carrying out some other intensive memory card operation in the backstage; And some intensive memory card operation is watched TV when moving in the backstage.
Yet, have been noted that some memory card operation (read and write) at least can cause the electromagnetic interference (EMI) to the DVB-H frequency band.This EMI influences the DVB-H reception potentially unfriendly and can cause relatively poor DVB-H receiver sensitivity, and the minimizing that in fact causes the operational coverage area of DVB-H receiver.That is, than the absent variable situation of EMI, DVB-H receiver, and therefore portable terminal, thus need more close reflector receive acceptable TV signal.
There are two kinds of main EMI sources: the interface between memory card self and portable terminal electronic equipment (such as phone engine) and the memory card.
About the EMI that memory card is introduced, the amount that has been found that this EMI is variable, and can seriously depend on the manufacturer of memory card.
The EMI that interface between phone engine and the memory card is introduced can change according to the details of portable terminal and memory card reader structure.For example, the terminal pin (electric connector) of memory card reader and memory card reader main body self possibility shielding are relatively poor, and this has caused an EMI source.Making it complicated is the following fact, and promptly modern portable terminal can adopt many multi-form structures.For example, if portable terminal is implemented (two PWB) by two circuit blocks, a piece will comprise that usually baseband engine and another piece will comprise memory card interface usually so.In this case, the memory card interface between the PWB piece can be served as another EMI source, because the electrical interconnection between the piece can be at least in part realized by the wiring of radiation EMI potentially.
Although the use of the mechanical masking of memory card reader can help reducing the amount of EMI, it can also reduce the availability of memory card reader potentially, because for example can improve the requirement of general form factor.
