acVIDEO DESCRIPTION AND SPECIFICATION
The acVIDEO Base accepts a composite NTSC signal from a VCR, CATV set-top-box (STB), laser disk player or satellite receiver via a standard coaxial cable. The acVIDEO Base injects composite FM video and stereo audio signals onto the premises power line, making it available to all outlets in a single family home or apartment.
The signal is retrieved with an acVIDEO Receiver. The acVIDEO Receiver extracts the signal from the power line, making it available over the video and stereo audio baseband to a second TV. Multiple receivers may be used, multiplying the viewing ability in the home. All premium services provided through the set top box are available at the second TV, without the expense of additional permanent cabling and the monthly set-top-box fees.
Channel selection at the second TV is accomplished through the use of an integrated infra-red remote control. An infra-red detector attaches to the acVIDEO Receiver, and picks up all infra-red transmission from either a universal remote or manufacturers remote. It then transmits the signal back to the source, where an infra-red emitter located in front of the source transmits the information to the tuner (VCR, set-top-box, laser disc player, etc.).
Combining other product features, VideoCom has the ability to introduce several variations of the acVIDEO line. Combining the acVIDEO and the acPHONE capabilities provides a simple way to both authorize pay-per-view (PPV) events from the TV, as well as circulate the image around the home.
VideoCom's acVIDEO can be easily adapted to other television systems like PAL and Secam as well as to different voltage power lines such as 220 V.
acVIDEO Product Functionality
The acVIDEO Video Base plugs into an electrical outlet near the television in the primary viewing room. A composite video and stereo audio signals from any interactive home terminal (e.g., satellite receiver, CATV set top box, cable ready VCR, laser disc player) is accepted via a standard coaxial cable. The video signal is Frequency Modulated to a specific band in the 15-30 Mhz range and injected in the premises electrical wiring, making it available to every room in a single family home.
The acVIDEO Video Receiver may be plugged into a standard electrical outlet near a television in a secondary viewing room. A RF signal is extracted from the electrical line and Frequency Demodulated to baseband. The video and stereo audio signals are delivered to the secondary television via a standard coaxial cable.
In less technical terms, a program source, for instance, a VCR, can be connected to the base unit (transmitter) from the output side through the RCA connector and cable of the VCR. Whatever program that is being output from the VCR, whether it be a tape or a selected channel, is immediately available at any 110 volt outlet in the home. A TV can then be connected to a receiver unit through the RCA connector and cable plugged in anywhere in the house and receive the program being output by the VCR. The program source can be another TV, a satellite receiver, a CATV set top box, etc.
For optimal convenience, the acVIDEO Video System offers an integrated remote control capability. The acVIDEO Video Receiver accepts control signals via a miniature infra-red detector located at the secondary television. The infra-red detector connects to the acVIDEO Video Receiver via a standard headphone cable and phono plug. The control signal is frequency shifted to a specific band in the 5.5 Mhz range and injected into the electrical line. At the acVIDEO Video Base, the control signal is extracted from the electrical line and frequency shifted to the source band. A miniature infra-red emitter connects to the acVIDEO Video Base via a headphone cable and plug. The infra-red emitter is positioned at the infra-red detector of the interactive home terminal and secured by a reusable adhesive. The consumer may use either a manufacturer supplied or universal remote control to command the interactive home terminal directly in either the primary viewing from or from any acVIDEO Video Receiver location.
The acVIDEO Video System responds to the documented demand for two or more video outlets among interactive services consumers with the benefits of instant "cable-free" installation, location flexibility, and the increased pay-per-view buy rates associated with impulse pay-per-view technology convenience from any room in the home.
acVIEW Monitoring Product Functionality
The acVIEW Monitoring Base plugs into an electrical outlet near monitoring site. Baseband video and audio signals are accepted from camcorders or palmcorders via RCA phono cables. The video signal is frequency shifted to a specific band in the 6-30 Mhz range and injected into the premises electrical wiring, making it available to every room in a single family home.
The acVIEW Monitoring Receiver may be plugged into a standard electrical outlet near a television in a secondary viewing room. A composite RF signal is extracted from the electrical line and frequency shifted to baseband. The video and audio signals are delivered to the secondary television via a standard coaxial cable.
The acVIEW responds to the rising demand in home and business security. The Electronics Industry Association (EIA) estimates that consumer installable security equipment is one of the fastest growing markets in consumer electronics. The acVIEW also responds to families that would like to monitor their infant, increasing the utility of pre-purchased video recording equipment. The acVIEW works in conjunction with camcorders and palmcorders to allow remote monitoring of infants, or potentially dangerous situations or locations, such as swimming pools or workshops.
