Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If application programs are delivered via broadcasting waves using FLUTE sessions, then the delivery mechanism is established, but the reliability of acquisition and execution is not yet ensured
Solution Approach 1:
The patent applies preliminary action by verifying the receiver's capability to execute the application program before attempting acquisition. The control section checks capability information in advance, and only when capability is confirmed does the system proceed to acquire the application program via FLUTE session. This prevents wasted transmission resources and ensures reliable execution.
Solution Approach 2:
The patent implements feedback through the capability verification mechanism. The control section receives capability information about the receiver's execution ability, processes this feedback, and据此 determines whether to initiate application program acquisition. This feedback loop ensures that only compatible receivers acquire and execute applications, enhancing overall system reliability.
2Reliability
If the receiver verifies capability before acquisition, then execution reliability is improved, but the acquisition process becomes more complex
Solution Approach 1:
The control section performs capability verification as a preliminary step before initiating application program acquisition. By checking whether the receiver has the necessary execution capability in advance, the system ensures that only compatible applications are acquired and executed, thereby improving execution reliability without requiring complex runtime verification mechanisms.
3Adaptability or versatility
If application programs are acquired from multiple sources (broadcasting wave or Internet), then availability is improved, but the acquisition mechanism becomes more complex
Solution Approach 1:
The patent applies universality by designing the application acquisition mechanism to handle multiple sources (broadcasting waves via FLUTE sessions and Internet) through a unified control framework. The control section determines the appropriate source based on capability verification and system state, allowing the same receiver to acquire applications from either or both sources without requiring separate specialized systems for each source.

AI summary
The present technology relates to a receiver, reception method, program, and information processing system that can provide an application program to be executed in response to AV content. A control section acquires TPT based on trigger information obtained from a broadcasting wave or the identification result of the ACR identification process. The control section pinpoints a command corresponding to the trigger information based on the acquired TPT. A flute processing section, in accordance with the pinpointed command, refers to an FDT pinpointed by an SMT and NRT-IT thereby acquiring a data broadcasting application transmitted as NRT content for NRT service using a FLUTE session. The control section controls an operation of the acquired data broadcasting application. The technology is applicable to a television receiver adapted to receive a digital television broadcasting signal.
