Solution Overview

Problem

Conventional broadband networks face challenges in flexibly controlling user authority and access to video services, particularly due to the difficulty in managing multicast protocols, which limits the development of broadband video services.

Innovation Solution

A method and access apparatus that determine permissible program lists and multicast IP addresses based on preset relations, allowing for flexible control of user access by receiving video program requests and forwarding video flows only to authorized users, thereby implementing user authentication and authority control near the user side.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multicast protocols are used for video service delivery, then video services can be delivered efficiently, but flexible control of user authority and access is difficult

Engineering Contradiction:
Improvevideo service delivery efficiencyVSAvoiduser authority control flexibility
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The patent introduces an access apparatus as an intermediary device between the multicast network and user terminals. This apparatus includes a control unit that intercepts and processes user requests, checking authorization information and managing multicast group membership. The intermediary enables flexible authority control by filtering and managing multicast traffic at the access point, resolving the contradiction between efficient multicast delivery and flexible user authority control.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If protocol-based multicast control is implemented, then standard video services are provided, but user authentication and authority control are limited

Engineering Contradiction:
Improvestandard video service provisionVSAvoiduser authentication and authority control
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The access apparatus autonomously performs authentication and authority control functions by maintaining local authorization information and automatically checking user credentials. The control unit self-manages multicast group membership by automatically adding or removing terminals based on authorization results. This self-service mechanism simplifies user authentication operations while maintaining reliable standard video service provision through protocol-based multicast control.

Inventive Principle:
Principle #25Self-service

AI summary

The present invention provides a method for accessing broadband video service, including: determining a port of an access apparatus, wherein the port receives a video program request carrying a requested multicast program IP address; determining a permissible program list corresponding to the port of the access apparatus according to preset relations between ports and permissible program lists, wherein at least one of program numbers is recorded in the permissible program list; determining multicast program IP addresses corresponding to the program numbers; and requesting a video flow from the requested multicast program IP address when the requested multicast program IP address is in the multicast program IP addresses corresponding to the program numbers. The present invention also provides an access apparatus. Using of the method and the access apparatus allows taking control of user accessing video program under the broadband video service.
