IP Relay Apparatus for Camera System Video Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In camera systems used in broadcasting, the existing connection methods via triaxial cables or optical fibers require extensive time and effort for setup and modification, leading to complex configurations with redundant components due to the need for multiple camera control units (CCUs) and excessive wiring.
Innovation Solution
A camera system that packetizes video signals into IP packets for transmission over Ethernet networks, using a relay apparatus with an IP switch to select and output desired video frames, integrating control and selection functions to reduce the number of CCUs and wiring needed, and allowing for flexible system configuration and modification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple CCUs are used to handle videos from multiple camera apparatuses, then video selection capability is improved, but system complexity and wiring requirements increase
Solution Approach 1:
The patent merges the functions of multiple CCUs into a single relay apparatus that receives packetized video data from multiple camera apparatuses and performs video selection internally. This consolidation eliminates the need for multiple separate CCUs and their associated wiring, while maintaining the capability to select and output videos from any connected camera.
Solution Approach 2:
The relay apparatus is designed as a universal device that can handle video data from multiple different camera apparatuses simultaneously. It provides multi-functionality by performing packet reception, video selection, and output routing within a single apparatus, replacing the need for dedicated CCUs for each camera.
2Adaptability or versatility
If multiple CCUs are connected to a video live switcher, then video input options are improved, but the number of cable connections increases
Solution Approach 1:
The patent consolidates multiple video input paths into a single relay apparatus that outputs to the video live switcher. Instead of requiring separate cable connections from each CCU to the switcher, the system uses one relay apparatus with a single output connection, dramatically reducing the total number of cables while maintaining multiple video input options.
3Adaptability or versatility
If camera apparatuses are added or rearranged in the system, then system flexibility is improved, but time and effort for cable reconnection increase
Solution Approach 1:
The patent replaces the mechanical cable connection system with a packet-based digital communication system. Camera apparatuses communicate video data through packetized streams to the relay apparatus, which automatically routes and selects videos based on data packets rather than physical cable connections. This eliminates the need for manual cable reconnection when adding or rearranging cameras.
Solution Approach 2:
The relay apparatus is pre-configured to receive packetized video data from multiple camera apparatuses using standardized protocols. This preliminary setup allows cameras to be added or rearranged without requiring physical cable changes, as the system is already prepared to handle multiple input sources through digital packet routing.

AI summary
A camera system includes a plurality of camera apparatuses that output respective video data in a packetized format. A relaying apparatus receives the packetized video data from the plurality of camera apparatuses and relays selected selected packetized video data from a particular one of the plurality of camera apparatuses on a frame basis.
