Digital Video Frame Capture Unit for Consecutive Frame Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional recording equipment can only capture single video frames at a time, making it difficult for users to precisely record consecutive or fabulous frames from digital video broadcasts or DVDs, as they lack the capability to record multiple frames simultaneously.
Innovation Solution
A method and apparatus that continuously receive and decode digital video data, allowing users to capture and store consecutive frames by receiving a capture instruction, selecting desired frames, and performing editing functions, such as setting them as power-on or menu frames, with a capture unit, decoder, player, and storage unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional recording equipment is used to capture video frames, then a single video frame can be recorded, but it is difficult to precisely capture consecutive or fabulous frames
Solution Approach 1:
The patent segments the video frame capture process into multiple independent capture operations, allowing simultaneous capture of multiple frames at different time points. The capture unit is configured to capture a first video frame at a first time point and a second video frame at a second time point, enabling precise capture of consecutive or fabulous frames through segmented temporal sampling.
2Adaptability or versatility
If conventional recording equipment captures single frames, then device complexity is low, but the capability to record multiple frames simultaneously is lacking
Solution Approach 1:
The patent implements multi-functionality by enabling the recording equipment to perform both traditional single-frame capture and the new multi-frame simultaneous capture function. The capture unit is designed to respond to capture instructions and execute multiple capture operations, making the device adaptable to different capture scenarios without requiring complete redesign.
Solution Approach 2:
The patent applies preliminary action by pre-configuring the capture unit with capture instructions that specify multiple time points for frame capture. The system prepares the capture parameters and timing information in advance, allowing the capture unit to execute precise multi-frame capture when triggered, rather than calculating timing in real-time during capture.
3Measurement precision
If multiple frames are captured simultaneously, then frame capture precision is improved, but the time required for decoding and processing increases
Solution Approach 1:
The patent applies preliminary action by performing decoding operations in advance. The decoded video data is stored in a buffer or memory before the capture instruction is executed. When the capture unit needs to capture multiple frames, the decoding is already complete, and only the data copying and frame extraction operations are required, significantly reducing the time loss.
4Ease of operation
If consecutive frames are captured and stored, then user selection capability is improved, but storage requirements increase
Solution Approach 1:
The patent applies the extraction principle by selectively extracting only the necessary frame data for user selection and display. Instead of storing complete high-resolution video data for all captured frames, the system extracts key frame information and stores only what is needed for the user to view and select fabulous frames, reducing storage requirements while maintaining ease of operation.

AI summary
A method and an apparatus for capturing consecutive frames in digital video are disclosed. Through adding a function of capturing consecutive frames in digital video to digital televisions or digital recording equipments, the continuous fantastic frames in digital video can be displayed on the screen for users to watch and choose. Besides, with a recording function, those fabulous frames can also be preserved for the use of the follow-up view and demonstration. Finally, the purpose of capturing and storing best frames is achieved.
