Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current broadcasting communication systems face challenges in providing high signal transmission and reception performance for digital broadcasting services, particularly in supporting various reception methods for high definition digital televisions and portable devices, due to limitations in processing and transmitting L1-post signaling effectively.
Innovation Solution
A transmitter is designed to improve L1-post signaling performance by using arithmetic operations to pad zero bits into groups, ensuring adequate bit length for encoding, with a zero padder calculating the number of groups and padding additional zero bits based on predetermined criteria to maintain continuous signaling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If zero bits are padded to L1-post signaling to ensure adequate bit length for encoding, then encoding performance is improved, but device complexity increases
Solution Approach 1:
The L1-post signaling bit sequence is divided into multiple groups, and zero bits are padded to specific groups based on predetermined criteria. This segmentation approach allows systematic control of padding operations, improving encoding performance while managing processing complexity through structured group-based operations.
Solution Approach 2:
Zero bits are padded in advance to the L1-post signaling before encoding, based on predetermined criteria that determine which groups receive padding. This preliminary action ensures the bit sequence meets encoding requirements without requiring complex real-time adjustments during the encoding process.
2Reliability
If zero bits are padded by group unit based on predetermined criteria, then transmission performance is improved, but operation complexity increases
Solution Approach 1:
The bit sequence is segmented into groups, and padding operations are performed on specific groups based on predetermined criteria. This segmentation simplifies the operation by providing a clear structure for determining which groups need padding, reducing operational complexity while maintaining transmission performance.
Solution Approach 2:
Predetermined criteria are established that define parameters for padding operations, such as which groups receive padding and how many bits to pad. These parameter changes provide a systematic approach that improves transmission performance while making operations more manageable through clear rules.
3Manufacturing precision
If additional zero bits are padded starting from front end or back end of remaining groups, then bit alignment is improved, but processing complexity increases
Solution Approach 1:
The patent determines in advance whether to pad additional zero bits from the front end or back end of remaining groups based on predetermined criteria. This preliminary determination simplifies processing by establishing the padding direction before actual padding operations, improving bit alignment while reducing processing complexity through advance planning.
Solution Approach 2:
Predetermined criteria define parameters including the direction of padding (front end or back end) based on group characteristics. This parameter-based approach ensures precise bit alignment while managing processing complexity through systematic rules that determine padding direction.

AI summary
Provided are a transmitter, a receiver and methods of padding and depadding zero bits to an L1-post signaling. The transmitter includes: a zero padder configured to divide an information word into a plurality of groups, pad zero bits to at least one of the plurality of groups by group unit, and pad additional zero bits to at least one of the plurality of groups remaining after the zero bits are padded, thereby constituting the information word for encoding the L1-post signaling; and an encoder configured to perform encoding on the information word for encoding the L1-post signaling. The zero padder pads the additional zero bits according to a predetermined criterion, starting from a front end or a back end of the at least one of the remaining groups.
