MCDN Remote Viewing via Content Duplication and Transcoding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multimedia content distribution networks (MCDN) face challenges in providing seamless remote viewing capabilities across different terminal devices due to cumbersome integration of external equipment and restrictive remote viewing limitations.
Innovation Solution
A method and system for remote viewing in MCDN that involves transmitting and duplicating multimedia content from a first terminal device to a second terminal device, including transcoding for compatibility and obtaining digital-rights management (DRM) authorization, allowing remote viewing across various devices such as TVs, personal computers, gaming consoles, and mobile devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If external equipment integration is used for remote viewing, then remote viewing capability is provided, but system complexity and ease of operation deteriorate due to cumbersome integration
Solution Approach 1:
The patent merges the remote viewing functionality directly into the MCDN terminal devices by providing a remote viewing application that enables one terminal device to view content from another terminal device within the same network. This eliminates the need for separate external equipment while maintaining remote viewing capability, thereby reducing system complexity.
Solution Approach 2:
The patent makes terminal devices universal by enabling them to perform multiple functions: they can both display local content and remotely view content from other terminal devices through the remote viewing application. This multi-functionality removes the need for dedicated external remote viewing equipment, simplifying the overall system.
2Adaptability or versatility
If external equipment integration is used for remote viewing, then remote viewing capability is provided, but ease of operation deteriorates due to restrictive limitations
Solution Approach 1:
By combining remote viewing functionality within the MCDN ecosystem, the patent enables seamless operation between terminal devices. Users can remotely view content from any terminal device in the network without dealing with complex external equipment connections, improving ease of operation.
Solution Approach 2:
The remote viewing application creates a digital copy or stream of the content displayed on one terminal device and transmits it to another terminal device within the network. This copying mechanism enables flexible remote viewing without physical connection constraints, enhancing operational convenience.
3Adaptability or versatility
If content is duplicated and transmitted to second terminal device, then remote viewing is enabled, but processing time and energy consumption increase due to transcoding and DRM authorization
Solution Approach 1:
The patent employs transcoding to change the format parameters of the content to match the capabilities of the second terminal device. By efficiently adjusting parameters such as resolution and codec format, the system enables compatibility across different devices while minimizing the time penalty associated with format conversion.

AI summary
A method and system for remote viewing of multimedia content using a multimedia content distribution network (MCDN) is configured to duplicate multimedia content displayed on a first MCDN terminal device and route the duplicate multimedia content to a second MCDN terminal device. The MCDN terminal devices may be coupled to a local network at an MCDN client premises. The MCDN terminal devices may also include wireless telephony devices for mobile remote viewing functionality. The method may include transcoding of the multimedia content into a format suitable for the second MCDN terminal device.
