General

Applicability

This specification is intended to apply to all cable systems and to all receiving devices which may be directly connected to a cable system residential outlet, including, but not limited to, television sets, video cassette recorders, and converters (whether furnished by cable operators or independently acquired by subscribers).

Federal Regulations

This specification assumes that cable operators comply with all federal regulations, including the performance criteria given in 47 C.F.R. §76.605. To the extent that specific performance levels are given in this document, they are intended to supplement, not replace federal regulations. If conflicts exist between this document and the federal regulations, the stricter of the two will be applicable.

This specification assumes that television receiving devices comply with all federal regulations, including the performance criteria given in 47 C.F.R. §15. To the extent that specific performance levels are given in this document, they are intended to supplement, not replace federal regulations. If conflicts exist between this document and the federal regulations, the stricter of the two will be applicable.

Compliance Standard

The performance of newly manufactured receivers will vary as a result of normal manufacturing tolerances. Similarly, the performance of cable systems will vary as a function of daily operating variables. In recognition of the difficulty of attaining average performance levels which will assure that every receiver and every cable system will always combine to assure an adequate interface, each parameter in this document is to be met by 95% of receivers and 95% of the time by cable operators. In order to protect customers whose reception is adversely affected by non-conforming equipment or systems, each industry agrees to remedy such problems on an individual basis.
