Solution Overview

Problem

Current remote management standards for Set Top Boxes (STBs) are not reliable and flexible, relying on proprietary solutions based on SNMP, which is inadequate for efficient and effective management.

Innovation Solution

Implementing a remote management method using the Customer Premises Equipment Wide Area Network Management Protocol (CWMP) to manage STBs, enabling the transmission and reception of statistics related to MPEG2-TS packet reception, jitter buffer overruns, and underruns, and allowing for configuration and reset of these parameters, thereby enhancing management reliability and simplicity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If proprietary SNMP-based solutions are used for STB remote management, then implementation simplicity is maintained, but management reliability is insufficient

Engineering Contradiction:

Improvemanagement reliabilityVSAvoidimplementation complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies TR-069, a universal remote management protocol originally designed for DSL modems, to Set Top Boxes. This allows the STB to be managed using the same standardized framework as other CPE devices, improving reliability through proven protocols while maintaining implementation simplicity through reuse of existing management infrastructure and expertise

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent extends the TR-069 data model with STB-specific parameters including MPEG2-TS packet reception statistics, jitter buffer overruns, and underruns. This parameter extension allows reliable STB-specific management while maintaining compatibility with the existing TR-069 framework, avoiding complete protocol redesign

Inventive Principle:

Principle #35Parameter changes

2Measurement precision

If detailed statistics parameters are collected from STB, then management precision is improved, but data transmission volume increases

Engineering Contradiction:

Improvemanagement precisionVSAvoiddata transmission volume

Core Design Contradiction:

Measurement precisionVSQuantity of substance

Solution Approach 1:

The patent extracts only the most critical performance indicators from the STB, such as MPEG2-TS packet reception counts, jitter buffer overrun/underrun events, and stream synchronization status. By selecting only these key parameters for remote transmission, the system achieves high management precision for troubleshooting while minimizing uplink data consumption

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent implements selective statistics collection where only relevant performance metrics are gathered and transmitted based on management needs. This partial action approach provides sufficient precision for remote diagnostics without the overhead of collecting and transmitting complete device state information

Inventive Principle:

Principle #16Partial or excessive action

AI summary

A remote management method enabling a remote management server (20) to manage at least a device (23). In order to have a simple and reliable management, it comprises a transmission step of a CWMP command (72, 76) requesting retrieval of statistics parameters from the device related to reception of MPEG2-TS packets by the device.
