Mandate minimum Behavior Inter-Operatability with Transmission Consider only what is needed now and are known quantities key is affordability. For everything else, recommend & give guidance, but let the market decide. Key Operations (Real & Critical Scenario)

Specifying Functional Requirements for RF Section is not sufficient. Coverage Planning Requires understanding of the receiver behavior. Minimum Performance of the receiver must be known. (Sensitivity / Noise Figure) Industry using its knowledge of potential situations & experience in the field a comprehensive list of test have been developed
RF Performance Measurement is an expensive operation and adds significant cost to the end product. Efficient Testing is Key. All Potential Modes Runs into millions of test case taking many man years to complete. All Potential Frequencies
A proper understanding of the decode process & receiver characteristics allow efficient testing. All Potential Modes All Potential Combination/Frequencies Use a representative Modes: SFN/MFN? Coverage Area/Bit Rate? SFN Size? Indoor / Outdoor Reception Fixed/Mobile e.g. 5 Modes & 14 different test Provide Actual Figures and not formulas
The Receiver detects changes to broadcast and automatically updates the available services. e.g. Behavior of Receives during (1)Service Addition (2)Service Deletion (3)Multiplex Move (4)Multiplex Addition During ASO, Restacking is unavoidable. This will result in services and multiplexes moving position. In everyone s best interest that changes are found automatically.
Important that Arabic & English languages are supported in both TV Menus and Instruction manuals support A Digital Receiver has thousands of strings, so not easy to support all regional languages.
Unique Country features especially those which have a high per unit cost. There is no need to re-invent the wheel. Proprietary Technologies (e.g DRM) Expensive Technologies to implement HW Cost/SW Cost/ Licensing Cost Broadcasters/receivers will be captive to license holders. Difficult to predict the future - Technology is changing very fast Avoid Technology on its way out. Avoid Cutting Edge technology in minimum specification.
Type Approval can be very expensive process. SI/PSI Testsuites can be expensive to Purchase for Pretesting. RF Test Equipment is not cheap, even if only needed for pretesting. RF & SI/PSI Certification by External Test House can be pricey. Sony are cooperating with Regulators in Africa & Asia To develop RF & SIPSI Testsuites Focused on real scenarios that will have in the market. With the intention that Regulators will distribute Testsuites for a minimal fee. The Testsuites have been reviewed by key stake holders.
Self Test is more cost effective for Manufacturers If Manufacturer has invested large sums of money in RF measurement equipment, then it is counter intuitive to spend large sums of money for external RF Testing. Well know manufacturers have a valuable brand to protect. Self declaration and surveillance, random checks in market. External Type houses can lead to more robust market products Some manufacturers may lack necessary equipment and expertise. Unscrupulous Test houses may realize they get paid more when a receiver fails.

Please communise specification across Countries as much as possible. Please consult with all interested parties During the specification development Before introduction of Type Approval Regime. Please give manufacturers time to change product line up.
Feel free to send email, if any query in future.

Important that users are able to easily see the Signal information. During self installation of aerial. Or if any issues thereafter.
Even After Analogue Switch Off Many Consumers will not want to use DVB-T2 Tuner of idtv. Please give sufficient notice to change lineup. DVB-T2 DVR STB FTA DVB-T2 TV DVB-S2 STB DVB-T2 PAY STB
