TV Mobile Phone Refers To Mobile Phone As Terminal Device

television

TV mobile phone refers to a technology or application that uses mobile phone as terminal device to transmit TV content. There are three main ways to realize mobile TV business:

1. Realize by using cellular mobile networks, such as Sprint in the United States, China Mobile in China and China Unicom, which have launched mobile TV services in this way.

2. South Korean operators plan to use satellite broadcasting.

3. It is a digital TV receiving module installed in the mobile phone to receive digital TV signals directly.

The way of using mobile network to realize: the mobile TV business launched by mobile operators in the United States and China mainly relies on the existing mobile network.

China Mobile's mobile TV business is based on its GPRS network, while China Unicom relies on its CDMA1X network. This kind of mobile TV service actually uses streaming media technology to push mobile TV out as a data service.

Both GPRS mobile phones and CDMA1X mobile phones need to install corresponding broadcast software on mobile terminals equipped with operating systems (generally PDA mobile phones and other high-end products), and the corresponding TV programs are organized and provided by mobile communication companies or through corresponding SPs.

It is a very novel idea to use satellite network to realize and use mobile phones to receive TV program signals broadcast by satellite. Only South Korea is promoting this mobile TV broadcasting mode (DMB). The corresponding standards of South Korea and Japan have been determined, and this module will soon be launched in these two places. The rest of the world will lag behind.

Samsung, which is responsible for producing such mobile terminals, said that the DMB module would increase the price of mobile phones by 20 to 30 dollars. Samsung expects that this DMB mobile phone and TV service will be launched in the third quarter.

The most promising mobile TV technology is through the integration of digital TV and mobile phone. In this way, a microwave digital TV receiving module needs to be installed on the mobile phone terminal, and the digital TV signal can be obtained directly without the link of the mobile communication network.

The mobile digital TV standard is only DVB-H in Europe and single-band retransmission standard in Japan. The full name of DVB-H is Digital Video Broadcasting Handheld. It is the transmission standard established by the European Digital Television Standards Organization (DVB) to provide multimedia services to portable/handheld terminals through terrestrial digital broadcasting networks.

The DVB-H standard relies on the DVB-T transmission system and enables mobile phones and other portable devices to receive radio and television signals stably by adding certain additional functions and improving technology. The DVB-H standard was approved by the DVB technical seminar group. Japan has formulated the "single band broadcasting" standard under its microwave digital TV broadcasting mode "ISDB-T" standard. Although the functions of these two technical specifications are equivalent, there are still great differences between them. Single-band broadcasting is to divide the frequency and reduce the bandwidth, while DVB-H uses the bandwidth of time-division digital multimedia broadcasting to transmit the data of each channel in pulse mode. Generally, the tuner circuit is closed at other times except for receiving the data of the required channel, so it can effectively reduce power consumption.

game

Game phones, that is, mobile phones with more emphasis on game functions. The feature is that there are buttons specially set for the game or convenient for the game on the body, and the screen is generally not small. For example, Sony Ericsson Xperia Play Z1i.

HD film

High-definition movie mobile phones can meet the needs of users to enjoy high-definition movies anytime and anywhere. Generally, the screen size is large and the resolution is high, mainly focusing on the user's audio-visual experience. At the same time, large capacity batteries are needed to support watching movies for a long time. There are many kinds of screens with HD resolution (1024 × 768). For example, Samsung Note2, etc.

ultrathin

The camera function of iPhone 5V is very powerful in the ultrathin mobile phone collection. The iPhone 5 V supports 1080P full HD video capture. In addition to enhanced shooting stability, it also adds intelligent smiling face detection function, and can also take photos at the same time, which is similar to HTC One X. In addition, the Facetime function of the front camera also supports 3G network, and the camera used for video call can reach 720P HD level, and also has the function of smiling face detection. Although there is no change in the pixel parameters of the iPhone 5V camera, the richer and more practical function improvement still has a good performance. In addition to the unique color matching, I want to believe that it is definitely a symbol of status.
