After the prototype was demonstrated to the Canadian government, Shaw Cable agreed to fund a pilot project, which ran in Edmonton from 1993 to 1994. Rogers Cable then tested the V-chip system in Toronto and Vancouver. Subsequent V-chip tests in the USA include cable systems in Buffalo and Seattle plus tests by several cable channels. When that time arrives, use the computer connected to your closed-captioning encoder to insert program title and ratings data into the analog VBI or digital datastream of any program not already coded before arrival. The source of the video does not matter.
Auto sync the clock to make sure the V-chip data is encoded into the outbound signal in real time.
Whenever a V-chip in the home encounters a proscribed code, the chip blocks out the entire program with explanatory text appearing on the screen. Single scene blocking interrupts the storyline too much for most viewers, and viewers never knew how long to sit still and wait for the program to return. The V-chip is now ready for implementation only on analog systems. As digital TV enters homes, however, once every data packet can carry a V-chip code in the header, Collings expects parents will gain the ability to use the remote control to select an adult version of a show and then almost seamlessly shift to a softer version if their kids walk into the room. That's why he sees anolog implementation as an interim solution. .
