In a filing with the Securities and Exchange Commission, the Beijing-based company said it plans to offer 12 million American Depositary shares, each representing one ordinary share. China Digital TV said it expects the offering to price between $11 and $13 per ADS.

The company has also granted the underwriters the option to purchase up to an additional 1.8 million ADSs to cover any overallotments.

Assuming an offering price of $12 per ADS, China Digital TV estimates proceeds of about $131 million, or $151.1 million if the underwriters exercise their overallotment option in full.

The company plans to use proceeds from the IPO for research and development, sales and marketing, acquisitions and general corporate purposes.

China Digital TV develops software used in conditional access systems, which are a key component of pay-television platforms, and set-top boxes for digital TV subscribers. The company also sells smart cards that enable digital TV network operators to control access to their programs.

As of June 30, China Digital TV had installed its systems at 130 digital television network operators, according to the filing.

In the six months ended June 30, China Digital TV increased its profit to $12.2 million, from $3.4 million in the year-ago period. Revenue for the period grew to $21.7 million from $10.4 million in the first half of 2006.

The company said a majority of its revenue is derived from sales of its smart cards, which accounted for 88 percent of total revenue in the six months ended June 30.

Morgan Stanley, Credit Suisse, Piper Jaffray, CIBC World Markets and Needham & Co. LLC are listed as the underwriters of the offering.

China Digital TV plans to list its shares on the New York Stock Exchange under the symbol "STV."
