The preparation is advanced aiming at the practical use of the multimedia broadcast for the portable terminal using the VHF belt that becomes empty by ending ground analog Television Broadcasting on July 24, 2011 with steady steps.
The multimedia broadcast for the portable terminal is broadcasting located to “Next generation One Seg” that is scheduled to be executed by the width of 18MHz of VHF belt low band (90M-108MHz) and the width of 14.5HMz of VHF belt high band (207.5M-222MHz). “Multimedia broadcast for the whole country” region within the range of 10km in the maximum radius is scheduled.
The maximum resolution of H.264 and the image is common, and the maximum frame of 720×480 dots and images is common and 30 frames and the voice encoding methods are common common 3 methods the image encoding method of three kinds of technological methods adopted this time with MPEG-2 AAC+SBR+PS, MPEG Surround, and 5.1ch surround.
The ISDB-Tsb enhancing method based on the “MediaFLO” method that “ISDB-Tmm (ISDB-T for Mobile Multimedia)” method and U.S. Qualcomm based on the terrestrial digital broadcasting method of Japan promoted as a broadcasting method in the country and the method of ground digital voice broadcasting method “ISDB-Tsb (Services Digital Broadcasting-Terrestrial for Sound Broadcasting )” of Japan was formally decided.
The business model as the consignment broadcaster (program offer entrepreneur) that each company assumes somewhat has the difference by each company. For instance, the multimedia broadcast for the local block executed with VHF [ro-bando] is said, “The pay broadcasting model of the free classified ad model and each channel for whom it charges as well as a current terrestrial broadcasting is assumed” (benevolence Heisei era of TOKYO FM multimedia broadcasting business headquarters deputy general manager Gen). It is said that there is a terminal section money model by whom courtesy rates are included beforehand as service for the account model and the car navigation system that pays the charge when it watches downloaded contents in the price of the terminal in a pay broadcasting of the multimedia broadcast for this local block. “Model from whom the user did not have to pay the charge when the terminal was bought once, and the charge for the number of the terminal shipped from the terminal manufacturer was paid to the consignment broadcaster” and the Nihira deputy general manager explained the terminal account model whom TOKYO FM regarded.
On the other hand, it is said that the multimedia broadcast for the whole country of the VHF high band will assume the pay subscription model of both camps of ISDB-Tmm and MediaFLO and the monthly sum fixation. The Ishikawa president of the multimedia broadcast that promotes the ISDB-Tmm method describes, “Think about service of ..deserting.. [dai] by the monthly sum fixation”. President Masuda of media flow Japan project that promotes the MediaFLO method basis, too : in the monthly sum fixation and the yearned getting. ｢PPV (paper view) is prepared according to contents. Moreover, the free content is offered. ｣It explained. In addition,｢Contents suitable for my favor are chosen because the amount that can be accumulated in the cellular phone in a day is limited or some packages are prepared, and the download service will be selected from among that. However, even with the correspondence terminal excluding the contract user, these pay services cannot be received. ｣President Masuda explained solving.
Is the offer of the cellular phone that supports three methods possible?
At first, the service beginning is thought that the cellular phone becomes a main terminal to pull the market though a cellular phone, smart phone, car navigation system equipped with reception tuner, and special portable receiving terminals etc. are assumed as a receiver as for the receiving terminal of the multimedia broadcast. The doubt caused here is a combination of the broadcasting method with the telecommunications provider. It is “Is the reception function of ISDB-Tmm installed in the terminal of KDDI?”, and “Is the reception function of MediaFLO installed in the terminal of NTT DoCoMo?”
In the media flow Japan project that promotes MediaFLO, KDDI is a stockholder of the main. On the other hand, NTT DoCoMo is a stockholder of the main in the multimedia broadcast that promotes ISBD-Tmm. The media flow Japan project showed that there was no idea of installing the reception device of the ISBD-Tmm method by “Assumption of installing both reception functions as a practical matter was not basic” (president Masuda) and present though KDDI of the parent company participated in the ISDB-T multimedia forum. However,｢It is a user needs situation which kind of device to install. There is a possibility of becoming a judgment of installing the ISDB-Tmm reception function, too, if needs are high. ｣Content was given. Opinion similar as for Ishikawa president of multimedia broadcast. However, it was described, “Naturally, it was likely to become both installed directions if there was an expectation as the movement of the market to the MediaFLO method and both needs high, and exceeding the cost improvement (earnings), etc.”.
In addition, president Masuda is negative , saying that “Will give priority to MediaFLO of the VHF high band to have to overcome a technical problem concerning the reception performance like the antenna problem etc. of VHF [ro-bando] though KDDI puts the correspondence cellular phone equipped with the digital radio reception tuner of the ISDB-Tsb method of FM radio and VHF high band 7ch on the market” equipped with the reception function of VHF [ro-bando]. On the other hand, the Ishikawa president showed positive posture , saying that “It was possible to install it if VHF [ro-bando] was a technological convention named ISDB-Tsb of the ISDB-T family, and did not have the cost improvement because compatibility was a formal technology it high but there was something that both were able to be received by single-chip”. This is received, and the Nihira deputy general manager of TOKYO FM that promotes the multimedia broadcast of VHF [ro-bando] :. ｢I want to provide attractive service that corresponds to the cost improvement. Moreover, I think a technological problem including the problem of the antenna to be good when the place that can be jointly discussed is installed. ｣It talked.
Besides this, the point that becomes a problem when a different broadcasting method in one terminal is supported is and there is another. It is “Attestation and account system” needed when the pay service is offered. For instance, the necessity for extending and doing “Attestation and account” comes out from a different telecommunications provider when the pay service of MediaFLO is received by the cellular phone of NTT DoCoMo, and the pay service of ISDB-Tmm is received oppositely by the cellular phone of KDDI. The MediaFLO service performed in the United States is being provided by a telecommunications provider different from U.S. AT&T and U.S. Verizon Wireless. Moreover, the provided service is provided for car audio and a special portable terminal single MediaFLO it from November this year. Therefore, it is said that the terminal without the telecommunication facility is assumed, and the mechanism (the attestation and the account by way of the Internet with the terminal besides the broadcasting receiving terminal) has been achieved. There seems to be a possibility to attest and to come to be able to charge if this mechanism is used even when the pay service of ISDB-Tmm is received. The attestation and the account of the other multimedia broadcast of the pay service of MediaFLO seem to be difficult from “At first, the platform of NTT DoCoMo is used” (Ishikawa president) under the present situation.
