"We have found a killer application for the Bluetooth of the mobile phone, which makes the Bluetooth in the mobile phone use one." Yin Jun, CEO of Shanghai Pome Electronic Information Technology Co., Ltd. said to the reporter of "Electronic Engineering". He said, he took out a small white box with half the size of a business card from his pocket, and then took out a Dopod smartphone and continued, "This small white box is a CMMB receiver that will receive the CMMB mobile. Decoding the TV signal, transmitting the data stream (audio, video, data, etc.) to the intelligent terminal (including smartphone, laptop, netbook, PDA, PND, etc.) via Bluetooth, and installing a product for use with our products on the smart terminal. By playing the software, you can implement many functions of CMMB on these smart terminals."
It seems that this small white box is actually a Bluetooth digital TV adapter. It has built-in Taihe Zhiheng's CMMB demodulator, FCI's Tuner, CSR's Bluetooth chip and NAGRA's SMD chip. Pommi called it MOBVIEW MOW C66. "MOBVIEW MOW C66 has integrated CA and obtained the NAGRA CA certificate. At the same time, the product also won the bid for the terminal procurement project of China Broadcasting Satellite Mobile Broadcasting Co., Ltd., and entered the government procurement list. Through the quality inspection of the radio and television system." Yin Jun said. Up to now, more than 150 cities across the country have covered the CMMB signal. Due to the support of the CAS system, this product can be used throughout the country.
“This product is attractive to fashionable young people or white-collar workers.†Yin Jun believes. He explained that smartphones are gradually becoming the mainstream products among these people. However, since the mainstream smartphones on the market are from big brands around the world, such as HTC, Samsung, Nokia, Dopod, Motorola, etc., their product development is focused on In the global market, in their future product line, products that integrate digital TV functions will only account for a small fraction. "This situation restricts the enjoyment of mobile digital TV by these fashionable young people. In the Chinese market, mobile digital TV is gradually getting hotter. Nearly 200 cities will have CMMB signals this year. This is for the fashion crowd. Regret, and our product can make up for this regret.†He added, “Not only can make up for this regret, this compact, sophisticated Bluetooth digital TV adapter may become a new fashion product.â€
In addition, this product has two other important implications for the current market. First, due to current policy issues, CMMB mobile phone access time is still unclear, and large-scale brand terminal manufacturers are temporarily unable to launch mobile phones integrated with digital TV. This product can easily add digital TV functions to these mobile phones.
Another practical significance is the supplement to the current lack of indoor coverage of CMMB. Yin Jun explained: "Because CMMB has not yet achieved fine coverage, sometimes it is not possible to receive CMMB signals in deep rooms. At this time, this Bluetooth digital TV adapter can be placed at the window, thus solving the current difficulties." According to him, this product is welcomed by local radio and television.
Yin Jun also introduced another advantage of this Bluetooth adapter: in the long run, the CMMB protocol is still being improved, and subsequent functions and mode adjustments may continue for some time. MOBVIEW MOW can be upgraded by software. To increase or adjust the function, which can reduce the cost and risk of after-sales service.
MOBVIEW MOW supports a receiving frequency range of 470~860MHz, supports USB working mode, supports BPSK modulation mode, built-in large capacity, replaceable lithium battery, working time is 6~8 hours, "We bring it around, don't worry about battery charging The problem," he said. At present, the price of this adapter is about 800 yuan. The phones that have been matched include the Dopod Touch full range, the Motorola Q8, and the HP Hx2790. "We have tested the XScale 27X and 31X and Qualcomm's 72XX series. As long as the main frequency can reach 400MHz or above, Bluetooth 2.0 has no problem. The smartphones based on these processors can be matched, and other processors are being tested," he said. On the OS side, they have completed the player on PC and Windows Mobile, Symbian is doing it, and will soon be able to support Nokia's smartphone.
"In fact, this idea is common to many companies. But it is not easy to do a good job and make a mature solution. We are the first company to obtain China Mobile's certification and NAGRA CA certification." Yin Jun said.
