Summary of Hacking a weird TV censoring device

00:00:00 - 00:20:00

The YouTube channel technology connections showed a recent video in which the narrator takes a look at a TV censoring device known as the TV Guardian. The device filters out foul language from television and home video sources, and the narrator found an eBay seller who offered a unit for sale. The chip inside the device is a pick microcontroller with a 1.05 sticker, a microcontroller with 2K of ROM and 128 bytes of RAM, a ntsc line 21 decoder, a Japan radio Corporation 2207 video superimposer, a pick microcontroller with serial SPI interface, and two other chips. The data sheet reveals that when the org pin is tied to ground, the 8-Bit memory organization is selected. The PE pin is currently unconnected, but it may be used to enable or disable the chip. The video explains how to hack a TV censoring device by manipulating the program enable (PE) pin and clock pin. By connecting these pins to an Arduino, data can be extracted from the ROM chip. This hacker was able to extract the contents of a TV's ROM using an Arduino and a serial port. He found that the TV was censoring certain words, and that there were higher value bytes between words. The video discusses how

• 00:10:00 This hacker was able to extract the contents of a TV's ROM using an Arduino and a serial port. He found that the TV was censoring certain words, and that there were higher value bytes between words.
• 00:15:00 The video discusses how a TV censoring device blocks certain words, and how by decoding the byte codes, it is possible to find out which words are allowed and which are not.
• 00:20:00 The YouTube video discusses a censoring device for televisions, and discusses how the device censors words based on their definitions. The video also discusses how the censoring device is different from the other whitelisted words, and provides no explanation for why these words are whitelisted.
