What is DVB-H?

DVB-H is a transmission standard developed by providing multimedia services through the ground digital broadcast network to handheld DVB-H system relies on the DVB-T transport system to allow the handheld terminal to stably receive the broadcast television signal by increasing a certain additional function and improvement technology. DVB-H can ensure that the mobile terminal receives digital TV programs under the mobile environment and micro power conditions, thereby well with 3G network applications. Digital TV Ground Broadcasting Standard DVB-T was released in 1997. The original intention is not for mobile reception, however, proves that DVB-T is very good in the high-size transmission mobile environment in Singapore and German trial operations (see Figure 1). However, due to large power consumption, mobile terminals that are not suitable for battery supply are received by the ground digital television broadcast network to receive digital TV programs. To this end, new technologies need to be introduced on the basis of DVB-T, forming a new transmission standard suitable for mobile terminals to receive ground broadcast digital TV programs. DVB-H (early DVB-X) standard, which started to study before and after 2002, is a handheld digital video broadcast. It is DVB (European digital TV broadcast standardization group, founded in 1993, consisting of more than 300 companies from 35 countries) The organization provides a transmission standard developed by the multimedia service to the portable / handheld terminal through the ground digital broadcast network. The DVB-H standard is considered to be a DVB-T standard extension application. However, compared to DVB-T, the DVB-H terminal has lower power consumption, mobile reception, and anti-interference performance are more preferable, so the standard is suitable for mobile phones, handheld computers, etc. Small-portable and portable devices are received through ground digital TV broadcast network. Digital TV signals do not occupy valuable band resources in mobile communication networks. In fact, the DVB-H standard is based on the current DVB-T transport system, which allows portable devices such as mobile phones to stably receive the standards of broadcast television signals by increasing a certain additional function and improvement technology.
