<p>The Digital Video Broadcast (DVB) PC-CARD interface is normally on a main PCB inside either a Set Top Box (STB) or digital Television (TV). This invention puts the PC-CARD interface outside the STB or TV main chassis or casing, hence making the TV or STB a lower price in the end market. The 'External PC-CARD Conditional Access Module (CAM) digital television accessory' can then be sold by either the STB / TV manufacturer as an add-on product, or it can be bundled (sold with) the Conditional Access card by the encrypted service provider. This invention pushes the additional cost associated with additional services (additional to what is normally transmitted as free programming) to the end user, hence making the basic STB or TV equipment lower cost in the market, thus realizing a more competitive end product.</p><p><Paragraphs id="pa02" num="0002" xmlns:base="http://www.sipo.gov.cn/XMLSchema/base">Note that the PC-CARD interface was formally known as the PCMCIA interface.</p> |
