TVs Can Be Enhanced Via "Smart Card" Slot
        
        
        
        The PC5220 and PC5225 from                   Philips are full-featured commercial                   televisions made exclusively for                   integrators desiring two-way                   interactivity for educational media                   access. A Smart Card Expansion                   Slot permits third-party control                   systems to be fully integrated                   inside the TV, eliminating set-top                   decoders and external data                   terminals.                   Other highlights are a Front                   Control Lockout, for selectively or                   completely disabling front control                   panel buttons, a Channel Guide,                   which provides an onscreen                   directory of channels and network                   affiliation, and a built-in Closed                   Caption Decoder.                   One may program the TV to tune in                   a specific channel when turned on,                   such as a campus bulletin board                   system. A Volume Limiter prevents                   audio from being raised, while a                   Volume Leveler detects variations                   in audio and adjusts to acceptable                   levels; both audio and video are                   automatically muted during a loss                   of signal.                   Both the PC5225 (25") and PC5220                   (20") support 181 channels and                   come with an 8-foot cord.
