Video Processing Apparatus Hardware Sharing for Multiple Outputs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional video processing apparatuses require additional scalers to generate multiple video outputs with different resolutions, increasing production costs.
Innovation Solution
A video processing apparatus employing a hardware sharing technique, utilizing a first, second, and third video processing block to generate multiple video outputs without the need for additional scalers, by reusing video processing circuits and paths to produce secondary video outputs from primary video outputs with the same content but different resolutions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an additional scaler is added to process secondary video output, then multiple video outputs with different resolutions can be generated, but production cost increases
Solution Approach 1:
The first scaler is configured to perform multiple functions: it processes the primary video input signal to generate the first video output signal, and simultaneously processes the first video output signal to generate the second video output signal. This multi-functional design eliminates the need for a separate second scaler, thereby reducing production cost while maintaining the capability to generate multiple video outputs with different resolutions
Solution Approach 2:
The patent merges the function of the first scaler and the second scaler into a single first scaler. The first scaler is designed to handle both the primary video input signal and the first video output signal, combining what would traditionally require two separate scaling components into one unified device, thus reducing overall system cost
2Ease of manufacture
If hardware sharing technique is employed, then production cost is reduced, but device complexity increases
Solution Approach 1:
The first scaler is designed with dynamic switching capability to handle different input signals based on operational mode. It can switch between processing the primary video input signal and processing the first video output signal, allowing the same hardware to adapt to different processing requirements without requiring separate dedicated hardware for each function

AI summary
A video processing apparatus includes a first video processing block, a second video processing block and a third video processing block. The first video processing block has a plurality of first video processing circuits disposed at a first video processing path, and is arranged for generating a first video output according to a first video input. The second video processing block has a plurality of second video processing circuits disposed at a second video processing path parallel with the first video processing path, and is arranged for generating an intermediate video output in response to a second video input, wherein an output signal of one of the first video processing circuits acts as the second video input fed into one of the second video processing circuits. The third video processing block is arranged for generating the second video output according to the intermediate video output.
