((a)) No person shall ship in interstate commerce, or import from any foreign country into the United States, for sale or resale to the public, apparatus described in subsection (s) of unless it complies with rules prescribed by the Commission pursuant to the authority granted by that subsection: , That this section shall not apply to carriers transporting such apparatus without trading in it.
((b)) No person shall ship in interstate commerce, manufacture, assemble, or import from any foreign country into the United States, any apparatus described in section 303(u) and (z) of this title except in accordance with rules prescribed by the Commission pursuant to the authority granted by that section. Such rules shall provide performance and display standards for such built-in decoder circuitry or capability designed to display closed captioned video programming, the transmission and delivery of video description services, and the conveyance of emergency information as required by . Such rules shall further require that all such apparatus be able to receive and display closed captioning which have been transmitted by way of line 21 of the vertical blanking interval and which conform to the signal and display specifications set forth in the Public Broadcasting System engineering report numbered E–7709–C dated May 1980, as amended by the Telecaption II Decoder Module Performance Specification published by the National Captioning Institute, November 1985. As new video technology is developed, the Commission shall take such action as the Commission determines appropriate to ensure that closed-captioning service and video description service continue to be available to consumers. This subsection shall not apply to carriers transporting such apparatus without trading it.
((c))
((1)) Except as provided in paragraph (2), no person shall ship in interstate commerce or manufacture in the United States any apparatus described in except in accordance with rules prescribed by the Commission pursuant to the authority granted by that section.
((2)) This subsection shall not apply to carriers transporting apparatus referred to in paragraph (1) without trading in it.
((3)) The rules prescribed by the Commission under this subsection shall provide for the oversight by the Commission of the adoption of standards by industry for blocking technology. Such rules shall require that all such apparatus be able to receive the rating signals which have been transmitted by way of line 21 of the vertical blanking interval and which conform to the signal and blocking specifications established by industry under the supervision of the Commission.
((4)) As new video technology is developed, the Commission shall take such action as the Commission determines appropriate to ensure that blocking service continues to be available to consumers. If the Commission determines that an alternative blocking technology exists that—
((A)) enables parents to block programming based on identifying programs without ratings,
((B)) is available to consumers at a cost which is comparable to the cost of technology that allows parents to block programming based on common ratings, and
((C)) will allow parents to block a broad range of programs on a multichannel system as effectively and as easily as technology that allows parents to block programming based on common ratings,
((d)) For the purposes of this section, and sections 303(s), 303(u), and 303(x) of this title—
