Broadcast Reception Device Remote Viewing via Server
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques for viewing broadcast programs recorded on a TV receiver are not convenient for users across various usage environments, as they require a tuner and transcoder for domestic use, preventing transmission and playback on portable terminals outside the home.
Innovation Solution
A broadcast reception device that allows users to select between recording program information and video content, with the option to record only program information or both, and communicates with a server to retrieve video content for playback on a portable terminal through a network, enabling remote viewing of broadcast programs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a tuner and transcoder are used for domestic broadcast reception, then broadcast programs can be received and displayed on TV, but the system cannot transmit recorded content to portable terminals outside the home
Solution Approach 1:
The patent divides the broadcast reception function into two independent parts: a tuner for receiving broadcast waves and a transcoder for converting encoding formats. This segmentation allows the transcoder to be separated from the TV receiver, enabling remote access to recorded content through network connections without requiring the complete domestic reception system.
Solution Approach 2:
The patent introduces a server as an intermediary component that stores recorded broadcast content and provides it to portable terminals via network. This server acts as a mediator between the broadcast reception system and mobile devices, enabling remote viewing without requiring direct connection between the TV and portable terminal.
2Ease of operation
If video content is recorded for later playback, then programs can be viewed at convenient times, but storage space is consumed and transmission becomes problematic outside home
Solution Approach 1:
The patent creates a network-based copy of recorded broadcast content stored on a server. Instead of storing the complete video content locally on the TV receiver, the system maintains a reference copy on the broadcast wave and transmits only necessary data to portable terminals when needed, reducing storage requirements while maintaining viewing flexibility.
3Reliability
If all program information and video content are recorded, then complete program data is available for playback, but transmission data volume increases and portability is reduced
Solution Approach 1:
The patent applies partial action by transmitting only the necessary program information and essential video data to portable terminals rather than the complete recorded content. The system selectively transmits data based on viewing requirements, maintaining sufficient reliability for playback while minimizing data volume for portable devices.
Data Source
AI summary
When a user inputs an operation of recording a broadcast program into a broadcast reception device, the broadcast reception device outputs, by a display video output unit of the broadcast reception device, a recording setting screen selecting a first recording method of recording program related information and not recording a video content of a broadcast program or a second recording method of recording the program related information and a video content of the broadcast program about a first program. When the first recording method is selected, the program related information is recorded and the video content of the broadcast program is not recorded. When the user inputs an operation of playing back the first program into the broadcast reception device, the broadcast reception device communicates with the server, receives the video content of the first program from the server, and outputs the video content by the display video output unit.
