Digital Television Receiver for Satellite Broadcast Transmission Specification The Bureau of Indian Standards (BIS) has recently issued revised guidelines for the implementation of IS 18112, which outlines the technical specifications for Digital Television Receivers (DTRs) capable of receiving satellite broadcast transmissions. These updates aim to improve interoperability, enhance consumer experience, and support standardization across the Indian digital TV ecosystem.

IS 18112 is a critical standard developed by BIS for ensuring that television receivers in India are fully compliant with the country's satellite broadcasting infrastructure. This standard applies to integrated digital televisions (iDTVs) and set-top boxes that directly receive free-to-air satellite TV signals without needing any external tuner or converter.

The updated guidelines specify new hardware and software requirements, ensure better signal reception quality, and facilitate the adoption of indigenous technology in compliance with the Make in India vision.

Key Features of the Revised Guidelines

1. Mandatory Compliance under CRS
All manufacturers, both domestic and international, must register their products under the Compulsory Registration Scheme (CRS) before marketing them in India.

2. Enhanced Technical Requirements
• Support for MPEG-4 and HEVC decoding
• DVB-S2 tuner compatibility
• Minimum audio/video output specifications
• On-screen display in multiple Indian languages
• Support for Logical Channel Numbering (LCN)

3. Testing & Certification
Products must undergo testing in BIS-recognized laboratories, covering parameters such as:
• Signal strength and quality handling
• Channel scanning and search features
• AV synchronization
• Emergency alert signal decoding (if applicable)

4. Standard Marking
After successful testing and registration, manufacturers must affix the Standard Mark (ISI Mark) on the product and packaging to indicate BIS compliance.

5. Implementation Timeline
A defined grace period is provided for implementation. Post-deadline, non-compliant products will not be permitted for sale in the Indian market.

• To ensure reliable and high-quality satellite TV signal reception
• Promote the use of standardized digital TV receivers
• Improve consumer satisfaction through uniform performance
• Align with national digital broadcasting policies
• Encourage local manufacturing and reduce dependence on imports

• Submit samples for testing and certification to BIS-approved labs
• Use appropriate labeling, packaging, and instruction manuals
• Update firmware/software as per BIS-prescribed formats
• Cooperate with surveillance and market inspection teams from BIS
