Communication Unit for Remote IPTV Access via Multicast Redirection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current IPTV systems are limited in providing remote access to locally transmitted multicast television channels, as they rely on closed network infrastructures and satellite dishes, which are not always available or practical for global access.
Innovation Solution
A communication unit that receives IPTV channels and sets up separate distribution channels using existing home IPTV multicast infrastructure, allowing remote access via any network with adequate bandwidth, without requiring specialized hardware or transponder servers, and enabling personalized video-on-demand services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If satellite dishes are used to receive local television channels from other parts of the world, then remote access to TV channels is achieved, but the solution requires satellite coverage which is not always available and involves complex installation with cryptos and set top boxes
Solution Approach 1:
The patent introduces a communication unit as an intermediary device that receives IPTV channels from a home network and redistributes them to user units in a visited network. This mediator approach eliminates the need for complex satellite dish installations by using standard network infrastructure (routers, switches) that are already present in most locations, thereby reducing installation complexity while maintaining remote access capability
Solution Approach 2:
The solution uses universal network devices (routers, switches) that can function in both home and visited networks, making the system adaptable to different geographical locations without requiring location-specific specialized hardware. The communication unit can operate with any adequate network infrastructure, providing universal access across different networks and locations
2Reliability
If closed network infrastructure is used for IPTV delivery, then local IPTV channels are available, but the infrastructure is only locally available and cannot provide global access
Solution Approach 1:
The patent segments the IPTV delivery system into two independent parts: a home network that provides reliable local channel availability and a visited network that provides geographical flexibility. The communication unit acts as a bridge between these segments, allowing the home network's reliable infrastructure to serve users in different geographical locations through the visited network, thus achieving both reliability and adaptability
Solution Approach 2:
The communication unit serves as an intermediary that connects the closed home IPTV network to the open visited network. It receives multicast IPTV channels from the home network and redistributes them to user units in the visited network, enabling geographical expansion without compromising the reliability of the original local IPTV infrastructure
3Adaptability or versatility
If specialized hardware in transponder servers is used for remote IPTV delivery, then remote access is enabled, but the implementation becomes costly and complex
Solution Approach 1:
The patent applies self-service by using standard network devices (routers, switches) that perform IPTV redistribution functions natively without requiring specialized hardware. The communication unit leverages existing network capabilities to achieve remote IPTV delivery, eliminating the need for expensive specialized transponder servers and reducing implementation costs while maintaining delivery capability
Solution Approach 2:
The solution replaces expensive specialized hardware with inexpensive standard network devices that can be easily deployed. The communication unit can be implemented using off-the-shelf routers and switches, significantly reducing the cost of remote IPTV delivery infrastructure while providing the necessary adaptability and versatility

AI summary
The present invention is arranged to provide an improved way of remote access to locally transmitted multicast television channels. The invention relates to a communication unit for communication of IPTV channels to at least one user unit (110). It comprises a receiver arranged to receive a set of IPTV channels, and a distribution channel set up unit arranged to set up one separate distribution channel (319) to each user unit (110) so as to distribute one of the IPTV channels in said set of IPTV channels over each distribution channel. The present invention further relates to a method for providing remote access to a first IPTV network.
