Regulatory issues do not appear suddenly at the 11th hour, and to my knowledge there has been no regulations issued by ANATEL in the last year that would affect the deal. The contract is/was between CCS TV and TV2U. If CCS TV ignored (voluntarily or by omission) a national regulation when they signed with TV2U, that is still a contractual issue, albeit being caused by a regulatory context. Regulations may have limited CCS TV in its rights to distribute or limited the geographical areas that it is allowed to cover. It may have also been a licensing issue with the international providers where CCS TV may not have been authorised to 'resell' the content, or resell it through a different media for which it was initially intended. Based on what I can gather it is probably a bit of both. Regardless, it is basically a very poor due diligence by TV2U resulting in a last minute contractual issue between it and CCS TV and delaying the deployment.
The same conditions will apply to any new deal TV2U envisages. Compliance with regulations on a national basis (filling all the right forms and pushing them through the bureaucracy) and negotiating distribution rights with international providers will take a hell of a lot more than 10 days.
