What Is the Difference Between a Digital FTA Receiver and a Decoder?

When many people think of satellite TV, they think of DBS (direct broadcast satellite) providers such as DirecTV and Dish Network that offer TV packages for a monthly subscription fee. But there is also another kind of satellite TV -- FTA (free to air) -- which gives users access wholesale cellphone to thousands of unencrypted digital channels with the proper equipment. This equipment includes components known as a receiver and decoder, which act in tandem to deliver the picture to a TV screen.
  1. Free to Air

    • FTA satellite TV typically involves programming that differs from what the major subscription providers offer. In the U.S., with DBS providers like DirecTV and Dish Network, dreambox dm8000 subscribers get access to all the major national and regional cable-based networks, while FTA channels are more likely to be niche offerings from religious and educational broadcasters. openbox s9 hd pvr However, one advantage of FTA is the ability to receive channels from foreign FTA broadcasters, provided the satellite is in an orbit and inclination that puts it within range of the satellite dish and receiver.

    Equipment

    • FTA satellite TV differs from DBS services not only in the types of channels received, but also with the equipment used to receive those channels. With DBS satellite TV, the satellite dish is stationary and receives all channels from a single satellite utilized by the DBS provider. FTA equipment usually involves the use of a dish that rotates to access the various satellites to which different FTA channels are uplinked. The positioning of the dish is controlled by the satellite receiver.

    FTA Receivers

    • An FTA satellite receiver is the device that receives the unencrypted channels down-linked from the various satellites and relays them to the TV. The viewer selects a channel to be viewed,wholesale silver jewelry and the receiver directs the satellite dish, with the use of a component called a DiSEqC (digital satellite equipment control) switch, to the position necessary to access the satellite. FTA receivers are available from a number of manufacturers with varying capacities, features and options, such as high-definition (HD) capability.

    FTA Decoders

    • Satellite TV signals are broadcast as a stream of encoded digital data, utilizing a compression format known as MPEG-2 or a newer version called MPEG-4. These signals must be translated into audio and video to be displayed by the TV, and this is the function of the decoder. The decoder is the component of the receiver that decompresses the digital data received through the satellite dish and makes the necessary translation that enables viewing. One difference between FTA and DBS decoders is that FTA decoders do not have the capability to decode the encrypted channels broadcast by DBS providers, as additional technology is required to unscramble the encryption during the decoding process.

Yihaodian, Backed by Wal-Mart, May Sell Shares

Yihaodian, the online supermarket whose investors include Wal-Mart Stores Inc. (WMT), may choose the U.S. for an initial public offering as it expands to challenge Chinese rivals including Alibaba Group Holding Ltd.’s Taobao.
The Shanghai-based retailer aims to break even in three years and will “most likely” sell shares to the public in the U.S., said Chairman Yu Gang, who co-founded the company in 2008 after working as a supply chain executive at Dell Inc. and Amazon.com Inc. There is no timetable for the sale, he said.
Yu expects to conclude the Wal-Mart investment agreement this month as Yihaodian aims for a larger slice of China’s online commerce market, which CLSA Ltd. estimates will almost double to 904 billion yuan ($140 billion) next year. Baidu Inc., China’s most popular search engine operator, and Sina Corp., which owns the nation’s third most-visited website, are among China-based companies that have chosen the U.S. for initial public offerings.
“We’ll do whatever it costs to secure a bigger slice of the market,” Yu, 52, said in a July 1 interview. “Market share is our top priority.”
To take on Taobao Mall, a unit of China’s biggest online commerce company, Yihaodian is expanding its workforce to about 3,000 employees by the end of this year from 2,000 now and adding a fifth warehouse this year, Yu said in Shanghai.
Quadrupling Sales
Sales at Yihaodian, which offers consumers 100,000 types of products from mayonnaise to disposable diapers, tablet computers and mobile phones, will almost quadruple this year to as much as 3 billion yuan from 805 million yuan in 2010, he said. Sales have been increasing about 28 percent a month on average, a pace Yu said he expects the company to keep.
Even at that rate, the online retailer has far to go to catch the market leaders, said Jim Tang, an analyst at Shenyin Wanguo Securities Co. in Shanghai.
“The rule for the e-commerce sector is that only the big get bigger,” Tang said by telephone. The challenge for Yihaodian is to boost its transaction volume and grab a bigger market share so that it can control costs, including purchasing, marketing and logistics, he said.
China’s Online Leaders
Taobao Mall led China’s business-to-consumer online market with 30 billion yuan of transactions in 2010, followed by 360buy Jingdong Mall with 10 billion yuan, according to IResearch Inc. Yihaodian ranks 10th, data from the Beijing-based research company shows.
Among China-based companies listed on U.S. exchanges, the four largest by market value are Internet businesses, Baidu, Sina, Netease.com Inc. and Ctrip.com International Ltd., according to Bloomberg data.
Yu founded Yihaodian with former Dell colleague Liu Junling, now the Chinese retailer’s chief executive officer. The two started the venture with their own savings.
Wal-Mart, the world’s largest retailer, agreed in May to buy an unspecified minority stake in Yihaodian to tap growth in China, the world’s fastest growing major economy. The companies didn’t disclose financial details.
