Broadcast Receiver Operation Mode Determination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing broadcast receivers lack the ability to efficiently process and protect IP-based broadcast data across various transfer protocols, including wired and wireless networks, while maintaining content protection and backward compatibility.
Innovation Solution
A method and system for determining an operation mode of a broadcast receiver that involves opening a resource manager session between a host device and a point of deployment, transmitting resource information, and setting an operation mode based on supported protocols, including IP protocol, to ensure secure and stable processing of broadcast data using conditional access from conventional cable cards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a broadcast receiver processes IP-based broadcast data across various transfer protocols, then the adaptability and versatility of the receiver is improved, but the device complexity increases
Solution Approach 1:
The patent introduces a protocol adapter as an intermediary component that sits between the network interface and the broadcast processing engine. This adapter handles protocol-specific details and translates them into a unified internal format, allowing the receiver to support multiple protocols without increasing core processing complexity. The adapter acts as a mediator that isolates protocol variations from the main processing logic.
Solution Approach 2:
The broadcast receiver is segmented into modular components: a protocol-specific adapter layer, a protocol-agnostic processing layer, and a service layer. Each protocol (IP, MoCA, etc.) has its own adapter module that can be independently configured and maintained. This segmentation allows the system to handle multiple protocols simultaneously while keeping each protocol's processing logic isolated and manageable.
2Reliability
If conditional access is implemented to protect transmission contents, then the security and reliability of content protection is improved, but the device complexity increases
Solution Approach 1:
The conditional access functionality is extracted into a separate, dedicated security module that operates independently from the main broadcast processing path. This security module handles encryption, decryption, and authorization operations separately, ensuring content protection reliability while preventing security logic from complicating the main processing architecture. The extraction allows security to be implemented as an overlay rather than integrated into every processing component.
3Adaptability or versatility
If the broadcast receiver supports multiple transfer protocols including MoCA and IP, then the adaptability is improved, but the ease of operation worsens
Solution Approach 1:
The broadcast receiver implements automatic protocol detection and selection capabilities. Upon initialization, the system automatically detects which protocols are available through the network infrastructure and configures itself to use the most appropriate protocol for each service. This self-service approach eliminates the need for users to manually configure protocol settings, maintaining ease of operation while supporting multiple protocols. The system autonomously manages protocol switching based on service requirements and network conditions.
Data Source
AI summary
A broadcasting receiver and a method of determining an operation mode of broadcasting receiver are disclosed. A host device transmits the resource information including A-mode resource information. And a POD receives the resource information and determining an operation mode based on the received resource information and operation mode setting information. The broadcasting receiver can protect content data received from all the transfer protocols including the wired/wireless network and the IP protocol, using the conditional access provided from the conventional cable card. The broadcasting receiver determines whether the host supports the A-mode and determines a method for receiving broadcast data, such that the operation mode of the broadcasting receiver can be properly established according to the determined result.
