Minimum specifications for DVB-T2 digital set-top boxes for the Ugandan market
The International Telecommunications Union (ITU) developed a digital terrestrial broadcasting frequency plan that setJune 15, 2015 as the date for migration from analogue to digital television broadcasting. Uganda Government, having developed and adopted a digital terrestrial broadcasting policy, set December 31, 2012 as the analogue switch-over date. The implementation of the terrestrial digital broadcasting was planned based on DVT-T technology.
The enhanced features on the DVB-T standard have motivated a number of countries to upgrade to the DVB-T2 standard. Uganda, along with EAC countries, has adopted the use the DVB-T2 standard. This upgrade implies that any subsequent rollout of digital broadcasting infrastructure in Uganda shall be on the DVB-T2 platform. However, in order to access programmes on the DVB-T2 platform, consumers will have to acquire DVB-T2 set- top boxes.
Consumers and vendors are advised to note that DVB-T2 compliant set-top boxes are capable of receiving and correctly displaying digital TV signals transmitted on both DVB-T and DVB-T2 digital platforms. On the other hand, a DVB-T compliant set top box is limited to only receiving DVB-T digital signal and is NOT capable of correctly receiving and displaying digital TV signals transmitted on a DVB-T2 digital platform.
Vendors of equipment are advised to cease any further importation of the DVB-T set-top boxes. All importations of the set-top boxes are, therefore, required to comply with the Government approved DVB-T2 system specifications. All equipment suppliers and vendors are further advised to obtain type approval of the set-top boxes from the Uganda Communications Commission in line with the Uganda Communications Act.
Authorised vendors/dealers of such equipment will be required to display, at the point of sale, a valid vendor authorisation and type approval certificate issued by the Commission. Consumers are encouraged to note the new DVB-T2 standard and therefore purchase set-top boxes that are compatible with the digital broadcasting platform.
In addition to the previous Public Notice of May 23, 2012, the Uganda Communication Commission, in accordance with its mandate under the Uganda Communications Act (Cap 106) subsections 4 (1) and 4 (j), has set the minimum DVB-T2 Digital set-top box specifications for the Ugandan market as follows:
