MANUFACTURERS are split over plans to make parental locks mandatory on digital TVs and set top boxes.

Parental locks let families control access to programs on digital TV based on their classification, such as G, PG or M. To watch a program above a certain classification requires a PIN.



The Australian Communication and Media Authority says it plans to make the locks a compulsory feature of all digital TV receivers sold in Australia.



"Mandating the inclusion of parental locks in digital receivers will support parents and guardians in protecting their children from inappropriate or harmful content on television," said ACMA chairman Chris Chapman.



However at least one manufacturer says the new rule is unnecessary.



"I don't think that this is something that ACMA should regulate," said Kogan Technologies founder Ruslan Kogan.



"If it's a feature that people legitimately want, then TV manufacturers will have to ensure that they include it in order to stay competitive."



Mr Kogan said there was a potential for consumers who don't want the locks to be penalised by the plan.



"For instance, people without young children will be paying for the research and development costs for this feature even though they will never use it," he said.



Other manufacturers were more sympathetic. The Australian Digital Suppliers Industry Forum, which represents digital TV and radio manufacturers, said its members "generally" supported the plan.



"In supporting it we understand it will promote a diversity of broadcasting choices," said ADSIF spokesperson Tim O'Keefe.



"Most manufacturers that are members of ADSIF already have parental guidance locks included in their products so it's not an impost."



However Mr O'Keefe said some companies were seeking time to sell existing products without parental locks before the new rule was enforced.



ADSIF represents most big-name digital TV manufacturers including Sony, Samsung, Panasonic, Toshiba, Sharp and LG.



Many new TVs and set top boxes already come with parental locks. Mr Kogan said his company's new range of set top boxes would also include the feature.



ACMA is calling for public and industry comment on how the plan would work and whether there should be any exemptions.
