Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable receivers used for terrestrial digital television broadcasting face challenges in efficiently acquiring channel selection information, as they need to operate in various locations, making initial scanning methods impractical.
Innovation Solution
A reception apparatus and method that utilize an IP transmission system to acquire channel selection information through a server via a network, using signaling information to access physical parameters for channel selection processing, including country codes, identifiers, and center frequencies, allowing efficient channel selection even without initial scanning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If initial scanning is performed to acquire channel selection information, then channel selection capability is achieved, but time consumption and operational complexity increase significantly for portable receivers
Solution Approach 1:
The patent applies preliminary action by having channel selection information pre-acquired and stored in a database before the portable receiver needs it. The reception apparatus uses communication means to obtain channel selection information from external sources (such as electronic service guides or signaling information) and stores it in advance, so that when channel selection is needed, the information is already available without requiring time-consuming initial scanning operations.
2Loss of information
If initial scanning is performed to acquire channel selection information, then complete channel data is obtained, but the complexity of the acquisition process increases
Solution Approach 1:
The patent introduces an intermediary approach by using communication means and databases as mediators between the portable receiver and channel selection information sources. Instead of directly performing complex scanning operations, the receiver communicates with external systems (through electronic service guides, signaling information, or databases) that provide pre-processed channel selection information, thereby simplifying the receiver's own operational complexity while ensuring complete information acquisition.
3Adaptability or versatility
If portable receiver operates in various locations without initial scanning, then mobility and efficiency are improved, but reliable channel selection becomes difficult
Solution Approach 1:
The patent applies universality by creating a system that works across multiple locations and conditions through a standardized database approach. The reception apparatus uses communication means to access universal channel selection information databases that contain location-specific channel data. This allows the portable receiver to reliably acquire accurate channel selection information in any location by querying the universal database system, rather than relying on location-specific initial scanning procedures.

AI summary
The present technology relates to a reception apparatus, a reception method, a transmission apparatus, and a transmission method, by which channel selection information can be acquired more efficiently. Provided is a reception apparatus, including: a reception unit that receives a broadcast wave of digital broadcasting using an IP (Internet Protocol) transmission system; a communication unit that receives first signaling information for acquiring broadcast content transmitted by the broadcast wave through communication with a server via a network; an acquisition unit that acquires, on the basis of the first signaling information, a physical parameter used in a physical layer in a hierarchy of a protocol of the IP transmission system; and a control unit that controls, on the basis of the physical parameter, operations of respective units that perform channel selection processing. The present technology is applicable to a portable receiver that is movable, for example.
