Dif­fer­ences be­tween the Blu-Ray and the DVD

Consumer Voice - - Comparativ­e Product Test | Blu-Ray Disk Players -

Por­ta­ble Blu-ray play­ers let you watch a movie any­time and any­where—great for long trips or waits at air­ports. You can also play movies on a lap­top com­puter with a built-in Blu-ray drive, though por­ta­ble play­ers are of­ten smaller and lighter and may of­fer more play­back op­tions. Most por­ta­ble play­ers look like small lap­tops mi­nus the key­board.

Keep­ing in view this up-and-com­ing trend, we bring to you In­ter­na­tional Con­sumer Re­search and Test­ing’s (ICRT) analy­ses wherein eight mod­els of Blu-ray disk play­ers from top six brands are tested and as­sessed. VOICE So­ci­ety is an as­so­ciate mem­ber of ICRT.
