Sec.  2.1400   Application for advance approval under part 73.

   (a) An original application for advance approval of a subscription TV (STV)
   system  and  one  copy  thereof must be filed by the party who will be
   responsible for the conformance of the system with the subscription TV
   standards specified in part 73 of the Rules. The application must include
   information  to  show  that the system conforms to the requirements of
    Sec. 73.644(b).

   (b) Advance approval may be applied for and granted in accordance with and
   subject to the following conditions and limitations:

   (1) A separate request for each different technical system must be made by
   the applicant in writing.

   (2) The applicant must certify that the application was prepared by or under
   the direction of the applicant and that the facts set forth are true and
   correct to the best of the applicant's knowledge and belief.

   (3) The applicant must identify the technical system by a name or type
   number and define the system in terms of its technical characteristics; a
   functional  block  diagram  must  be included. In addition, a complete
   description of the encoded aural and visual baseband and transmitted signals
   and of the encoding equipment used by the applicant must be supplied. These
   descriptions must include equipment circuit diagrams and photographs, and
   diagrams or oscillographs of both baseband and transmitted aural and visual
   signal waveforms and of the signal basebands and occupied bandwidths. If
   aural subcarriers are to be used for transmitting aural portion of the
   subscription program, for decoder control, or for other purposes, a full
   description and specifications of the multiplex subcarrier signals and all
   modulation levels must be included.

   (4) Preliminary test data must be submitted to show system capability with
   regard to compliance with the criteria set forth in  Sec. 73.644(b).

   (5) The applicant must identify the specific requirements of  Sec.  Sec. 73.682,
   73.687 and 73.699 (Figures 6 and 7) from which the transmitted signal will
   normally deviate.

   (6) The applicant must specify the method to be used in determining and
   maintaining the operating power of the transmitter if the procedures given
   in  Sec. 73.663 cannot be used due to suppression of the synchronizing pulses or
   for other reasons. If the operating power of the station must be reduced to
   accommodate  the  encoded  aural  or video signal, the operating power
   limitations must be specified.

   (7) The applicant must supply any additional information and test data
   requested by the FCC, to show to its satisfaction that the criteria given in
    Sec. 73.644(b) are met.

   (8) The information submitted by the applicant may be subject to check by
   field tests conducted without expense to the FCC or, if deemed necessary, at
   the laboratory or in the field by FCC personnel. This may include the actual
   submission of equipment for system testing under the provisions of  Sec. 2.945 of
   part 2 of the Rules.

   (9) No technical system will be deemed approved unless and until the FCC has
   notified the applicant in writing of the approval. Such notification of
   approval will be by letter to the applicant.

   (10) Approval by the FCC is limited to a determination that the particular
   technical system (the scheme for encoding and decoding the subscription TV
   signal) is capable of meeting the criteria given in  Sec. 73.644(b).

   (11) The FCC will maintain a listing of approved technical systems.

   (c) Multichannel sound may be transmitted for stereophonic or bilingual
   service with encoded subscription programs provided the technical operating
   specifications for this service are included in the application for advance
   system approval.

   (d) Subscriber decoder devices must comply with any applicable provisions of
   subpart H, part 15 of the FCC Rules for TV interface devices.

   (e) No modifications may be made by either the applicant or the user of a
   system having advance FCC approval that would change any of the operating
   conditions as submitted in the application for advance approval. Should
   system modifications be necessary, a new application must be submitted in
   accordance with the requirements of this section.
