(3) The Agency may, by means of a general act, issue instructions for the classification of programmes for which a licence has been issued under the Act governing the media. In doing so it must pay due regard to the public interest sought by media legislation and the interests of end-users. An operator referred to in the preceding paragraph that intends to change the programme location within the framework of the general act referred to in the general act referred to in the first sentence of this paragraph must inform the publisher of this programme and notify them of the new programme location not less than 30 days prior to the intended change. The classification of programmes under the general act referred to in the first sentence shall not impinge upon the right of an end-user to freely choose the order of programmes for his own use. (4) The Agency may, by decision and in accordance with the procedure referred to in Article 90 of this Act or the procedure referred to in the sixth paragraph of Article 90 of this Act, order an operator that provide electronic communications networks as referred to in the first paragraph of this Article to ensure access to application programme interfaces and electronic programme guides under fair, reasonable and non-discriminatory terms. (5) The Agency shall, by means of a general act, lay down the requirements for the interconnection of digital interactive television services and digital television equipment used by consumers. Article 113 (conditional access systems) (1) Conditional access systems for digital television and radio services operated in the EU market must have the necessary technical capabilities for cost-effective transcontrol that allow the possibility of full control by operators of public communications networks at local and regional levels of the services using such conditional access systems. (2) Operators of conditional access services that provide access to digital television and radio services and on whose access services broadcasters depend must provide all broadcasters, on a fair, reasonable and non-discriminatory basis, with technical services enabling the services to be received by subscribers by means of a decoder. (3) The operators referred to in the preceding paragraph must keep separate accounting records for conditional access services. (4) Holders of industrial property rights to conditional access products and systems must grant licences to manufacturers of consumer equipment on fair, reasonable and nondiscriminatory terms. When granting licences, such holders may not, through any conditions, prevent manufacturers from including common interfaces in the same product enabling connection to other access systems or elements specific to another access system, provided that they comply with the relevant and reasonable conditions ensuring the security of transactions of conditional access system operators. Article 114 (supervision) The Agency shall oversee the implementation of the provisions of this Chapter and the obligations imposed pursuant thereto. X.
