video screens hit paper magazines 娱乐周刊：液晶屏与杂志相结-凯发k8官网

the first video ¹ inside a print title has been published inside the american magazine entertainment weekly.

美国杂志娱乐周刊发行首刊带有液晶放像功能的印刷刊物。

the small screen, built into a cardboard（厚纸板） insert, contains an advert for pepsi max and trailers（追踪者，预告片） for us tv network, cbs.

there are also in-built speakers, so the viewer can hear the advert too.

"this is an extraordinary way to refresh how we interact with consumers," said pepsi-cola's chief ² officer, frank cooper.

chip technology is used to store the video - described as similar to that used in singing greeting cards - which is ³ when the page is turned.

the slim-line screens - around the size of a mobile phone display - also have rechargeable batteries.

each chip can hold up to 40 minutes of video.

bbc news' los angeles correspondent, rajesh mirchandani, said that the magazine advert was mounted inside a cardboard insert, so it was "instantly distinguishable from a normal flimsy（易坏的，脆弱的） page".

"you can't really ⁴（轻轻拂去，忽然摇动） through the magazine, because the 4-page insert that includes the video screen is ⁵ bulky（庞大的）.

"and when you do open up the relevant page, the actual advert takes several seconds to load and play and that's a lifetime's lag in the advertiser's world," he added.

copies of the magazine containing the screens are being sent out to several thousand subscribers in los angeles and new york.

cbs and pepsi won't say how much this limited commercial trial is costing, but manufacturers americhip told bbc news that a multi-thousand print run with built-in screens would cost in the region of us $20 (around £13) for each magazine.

this has prompted criticism from some quarters, saying that the internet has already been delivering video-embedded-in-text for some time.
