Baseband Packet Metadata Injection for ATSC 3.0 Adaptability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The transition from an MPEG2 transport stream system to an IP transmission system in digital broadcasting poses challenges in flexible system adaptation and correct processing due to differences in interpretation, leading to potential operational failures.
Innovation Solution
An information processing apparatus and method that adds additional information to baseband packets after error correction decoding, enabling correct processing and interpretation, even in cases of differing system interpretations, by including delimiter, precision time protocol, and BB packet information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an IP transmission system is introduced as a new transmission system, then more advanced services can be provided, but differences in interpretation and operation may cause processing failures
Solution Approach 1:
The patent applies preliminary action by adding additional information to BB packets before they are processed by the output unit. This additional information includes delimiters and metadata that enable correct interpretation of the packet structure. By preparing the packets with this extra information in advance, the system ensures that even when transmission system interpretations differ, the packets can be correctly processed without failures, thus maintaining reliability while adapting to new systems.
2Reliability
If additional information is added to BB packets, then correct processing can be ensured under different system interpretations, but packet structure complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the additional information into distinct components: delimiters that mark packet boundaries, metadata sections that contain interpretation information, and the actual BB packet content. This segmentation allows the output unit to process different parts of the packet structure separately, making the handling of complex information more manageable and systematic, thus reducing the effective complexity despite adding more information.

AI summary
Information processing with flexibility in interpretation of a standard is disclosed. In one example, an output unit adds additional information related to the BB packet to output the BB packet to a baseband (BB) packet after an error correction decoding process. The additional information includes at least one of a delimiter, a precision time protocol (PTP), or BB packet information. The BB packet information includes at least one of information indicating whether or not reception of the BB packet is stable, information indicating whether or not there is an error in the BB packet, a packet length of the BB packet, a relative physical layer pipe (PLP) ID of the BB packet, or an absolute PLPID of the BB packet.
