Sony says it will start a movie download service for its PlayStation 3 home console this summer in the U.S.

Kazuo Hirai, who heads Sony Corp.’s video game unit, said Thursday the service will be offered in Japan and Europe at later dates, although details won’t be available until next month.

Hirai said the company will strengthen its network services and further cut costs to achieve profitability in the Sony gaming business in the current fiscal year ending March 2009.

Apple Inc’s latest iPhone will be more profitable than any other product in its popular iPod line of music players, despite a price tag that is half of the previous iPhone, according to a study.

Helped by lower component costs, margins for the new iPhone are expected to exceed the 50 percent level achieved by Apple’s most popular media players, according to a preliminary study by research firm iSuppli Corp, released late on Tuesday.

“Apple’s iPod and iPhone products typically are priced about 50 percent more than their (materials and manufacturing) costs,” iSuppli said. “With the new iPhone sold at a price of $199 and the estimated subsidy of $300, Apple will achieve an even higher … margin.

Wireless phone carriers are expected pay a subsidy of about $300 to Apple for each of the new iPhones, iSupply said.

ISupply estimates manufacturing costs for Apple’s new high-speed iPhone totaled $173, compared with $265 for the original iPhone, released one year ago for about $500 with no subsidy. After what it called “component price reductions,” the initial iPhone carried a cost of $226.

“At … $173, the new iPhone is significantly less expensive to produce than the first-generation product, despite major improvements in the product’s functionality and unique usability, due to the addition of 3G communications,” said Dr. Jagdish Rebello, principal analyst for iSuppli.

A major consumer group, insurers together with Google Inc and Microsoft Corp said on Wednesday they have agreed to standards intended to speed adoption of personal electronic health records.

The electronic medical record field remains in its infancy. While U.S. privacy laws govern actions by medical providers such as doctors, there is little in the way of other established privacy, security and data usage standards despite decades of industry efforts.

Backers, which also include some doctors and employer groups, said they hope to break a stalemate in moving medical records online, sparked by consumer fears that their personal information will be abused, or held against them.

“A policy and privacy logjam … has constricted some of the consumer uptake of these services,” said James Dempsey, deputy director at the Center for Democracy and Technology, a privacy rights group that accepts some industry funding.

Principles for personal health records include an audit trail to track use of the data, a dispute resolution process for consumers who believe their personal information has been misused and a ban on using data to discriminate in employment.

Also signing on to the principles are WebMD Health Corp; Consumers Union, which publishes Consumer Reports; seniors’ lobbying group AARP; and America’s Health Insurance Plans, representing big insurers such as Aetna Inc.

Although a large Internet service provider has backed away from technology that tracks subscribers’ Web use in order to deliver personalized advertising, two other broadband companies said Wednesday they are BurlingtonFreePress.com AP NEWS”>still considering whether to deploy it.

Phone companies Embarq Corp. and CenturyTel Inc. have both completed trials of the same tracking system, from online advertising company NebuAd Inc., and are now considering whether to proceed.

The largest U.S. Internet provider that had been actively looking at Web tracking, Charter Communications Inc., announced Tuesday that it had canceled its planned test because customers had raised concerns.

The technology gathers data on the interests of Web surfers by looking at the sites they visit. It passes the information to online advertising companies, without revealing a surfer’s identity, so they can display more relevant ads on Web sites. For instance, a surfer who visits sites about dogs might see more banner ads for dog food.

The system has been criticized by privacy advocates and legislators. Rep. Edward Markey, D-Mass., and Rep. Joe Barton, R-Texas, wrote to Charter asking it to put the test on hold to give time for discussions. Markey chairs the House Subcommittee on Telecommunications and the Internet.
