China Multimedia Mobile Broadcasting

China Mobile Multimedia Broadcasting (CMMB) is a mobile television and multimedia standard developed and specified in China by the State Administration of Radio, Film, and Television (SARFT). It is based on the Satellite and Terrestrial Interactive Multiservice Infrastructure (STiMi), developed by TiMiTech, a company formed by the Chinese Academy of Broadcasting Science. Announced in October 2006, it has been described as being similar to Europe's DVB-SH standard for digital video broadcast from both satellites and terrestrial repeaters to handheld devices.

It specifies usage of the S-band/U-band and occupies 25 MHz bandwidth within which it provides 25 video and 30 radio channels with some additional data channels. Multiple companies have chips that support CMMB standard - Innofidei who was the first with a solution March 28, 2007,

Other manufacturers, such as Unique Broadband Systems, were quick to enter the race and grab a share of the handheld broadcasting market with their hardware platform supporting both CMMB and DTMB (as well as others) standard waveforms.

Vice president

A vice president (in British English: vice-president for governments and director for businesses) is an officer in government or business who is below a president (managing director) in rank. The name comes from the Latin vice meaning "in place of". In some countries, the vice president is called the deputy president. In everyday speech, the abbreviation VP can be used.

In government

In government, a vice-president is a person whose primary responsibility is to act in place of the president on the event of the president's death, resignation or incapacity. Vice presidents are either elected jointly with the president as their running mate, or more rarely, appointed independently after the president's election.

Most governments with vice presidents have one person in this role at any time, although in some countries there are two or more vice-presidents. If the president is not present, dies, resigns, or is otherwise unable to fulfill their duties, the vice president will generally serve as president. In many presidential systems, the vice president does not wield much day-to-day political power, but is still considered an important member of the cabinet. Several vice presidents in the Americas held the position of President of the Senate; this is the case, for example, in Argentina, the United States, and Uruguay. The vice president sometimes assumes some of the ceremonial duties of the president, such as attending functions and events that the actual president may be too busy to attend; the Vice President of the United States, for example, often attends funerals of world leaders on behalf of the president.
