Information Management Server Program Frame Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional information providing systems take a long time to search for and match pertinent information about commercial or program announcements, as they notify the information management server of the date and time of the whole program during inquiries, leading to prolonged search durations.
Innovation Solution
The system reduces search duration by using program sequence and frame scheduling information to identify the specific broadcast time of the video/audio information, allowing the information management server to quickly retrieve pertinent information based on playback history, without relying on the date and time of the whole program.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the conventional information providing system uses the date and time of the whole program to search for pertinent information, then the system can retrieve information about commercials or program announcements, but the search duration becomes excessively long
Solution Approach 1:
The patent segments the program structure by introducing program sequence information that divides the program into distinct frames (program frames, commercial frames, program announcement frames). This segmentation allows the system to directly search within specific frame types rather than searching the entire program duration, significantly reducing search time while maintaining complete information retrieval capability
Solution Approach 2:
The patent adds a temporal dimension to the search process by using frame scheduling information that specifies exact broadcast times for each frame type. Instead of linear searching through the entire program, the system can jump directly to relevant time points, transforming a one-dimensional search into a multi-dimensional search that incorporates precise temporal positioning
2Measurement precision
If the system performs matching search using video and acoustic information of the whole program, then it can identify the commercial or program announcement, but the matching search process takes a long time
Solution Approach 1:
The patent extracts only the necessary video and acoustic information from specific frames (program frames, commercial frames, program announcement frames) rather than processing the entire program. By extracting information only from relevant frames identified through program sequence information, the system maintains high matching accuracy while dramatically reducing the amount of data that needs to be processed
Solution Approach 2:
The patent performs preliminary organization of program information by creating program sequence information and frame scheduling information before the actual matching search. This preliminary action pre-structures the data so that during the matching process, the system can directly access pre-organized frame information without performing extensive preliminary searching, thus reducing overall search duration

AI summary
Recording-capable receiver 3 includes broadcast receiving unit 302 for receiving video/audio stream; storage unit 305 for storing the video/audio stream and storage time information; playback unit (decoder 306, video output unit 307, audio output unit 308) for playing the video/audio stream stored; control unit 309 for extracting the storage time information corresponding to the video/audio information in the video/audio stream played back; and communication unit 310 for transmitting the storage time information extracted to information management server 2 and for receiving the pertinent information. The information management server 2 includes storage unit 203 for storing pertinent information to specific video/audio information along with time information; retrieval unit 204 for extracting appropriate pertinent information by comparing the storage time information transmitted from the communication unit 310 with the time information stored in the storage unit 203; and communication unit 201 for transmitting the pertinent information extracted to the recording-capable receiver 3.
