Audio Channel Setup Using Server-Supplied ARC/eARC Settings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic apparatuses face challenges in distinguishing between abnormal and normal path settings during communication establishment, leading to latency due to timeouts and inability to simultaneously identify audio output device characteristics, especially when using HDMI-based audio transmission methods like ARC and eARC.
Innovation Solution
The electronic apparatus includes a processor that requests and receives setting information from a server to determine the optimal data transmission method for communication with another device, allowing it to adapt communication methods based on received information and avoid timeouts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the first electronic apparatus waits for a timeout period to identify the operation state of the second electronic apparatus, then connection establishment is ensured, but latency is generated and connection time is increased
Solution Approach 1:
The sink device pre-generates and stores setting information indicating its operation state (ARC or eARC mode) before any source device connects. When a source device connects, it retrieves this pre-prepared information immediately, eliminating the need to wait for timeout periods to determine the sink's operation state.
Solution Approach 2:
A communication channel acts as an intermediary to transmit the setting information from the sink device to the source device. This intermediary channel allows the source device to obtain the sink's operation state information without directly waiting for timeout responses, thereby reducing connection latency.
2Productivity
If the first electronic apparatus attempts eARC connection without knowing the second electronic apparatus's setting information, then connection attempt is made, but path setting confusion occurs between abnormal and normal settings
Solution Approach 1:
The sink device prepares and stores its operation state information in advance before any connection attempt. This preliminary preparation ensures that when the source device connects, it can immediately retrieve accurate setting information, avoiding confusion between abnormal and normal path settings.
3Reliability
If timeout waiting is implemented to identify operation state, then connection reliability is maintained, but audio output delay time increases
Solution Approach 1:
The sink device generates and stores setting information indicating its operation state before any source device connects. This preliminary preparation eliminates the need for timeout waiting during connection, thereby reducing audio output delay time while maintaining connection reliability through accurate pre-known settings.

AI summary
A first electronic apparatus includes memory storing instructions, a first communication interface, a second communication interface, and at least one processor, where the instructions, when executed by the at least one processor individually or collectively, cause the first electronic apparatus to, based on the first electronic apparatus being connected to a network through the first communication interface, control the first communication interface to request, from a server, setting information on a first data transmission method of a second electronic apparatus, receive the setting information from the server through the first communication interface, and control the second communication interface to perform communication with the second electronic apparatus based on the setting information.
