Femtocell Gateway Transcoding for External Terminal Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies fail to enable seamless decoding and display of video and audio content stored at home on external terminals outside the home, due to differences in codec, screen size, bit rate, protocol, and file format between the content and the terminal capabilities.
Innovation Solution
A femtocell gateway apparatus that includes a control signal conversion unit to identify terminal type, a reception unit to receive video and audio streams, a conversion unit to transcode and perform file format conversion, and a transmission unit to send the converted content using appropriate protocols, allowing the content to be decoded and displayed on external terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If content is stored in home devices with specific codecs and formats, then content quality is preserved, but external terminals with different capabilities cannot decode or display the content
Solution Approach 1:
The gateway apparatus dynamically changes the parameters of the content stream (codec type, resolution, bit rate, file format) based on the terminal's decoding capabilities. When a terminal requests content, the gateway retrieves the original high-quality content from home devices and transcodes it into multiple versions with different parameters, selecting the appropriate version that matches the terminal's capabilities, thus resolving the contradiction between preserving original quality and ensuring terminal compatibility
Solution Approach 2:
The gateway apparatus acts as an intermediary between home content storage devices and external terminals. It receives content from home devices in various formats, processes and converts the content according to terminal requirements, and delivers the appropriately formatted content to external terminals. This intermediary function allows the original content to remain unchanged in home devices while providing compatible versions to diverse terminals
2Adaptability or versatility
If protocol conversion is implemented to support multiple terminal types, then terminal compatibility is improved, but system complexity increases
Solution Approach 1:
The gateway apparatus is designed with multi-functional capabilities to handle various protocols (HTTP, RTP, RTSP, RTCP) and content formats simultaneously. It incorporates universal protocol conversion functions that can adapt to different terminal types without requiring separate dedicated systems for each protocol, thus improving terminal compatibility while controlling system complexity through consolidated multi-functional design
Solution Approach 2:
The gateway apparatus segments the protocol conversion process into distinct functional modules, each handling specific protocol conversions or content transformations. This modular segmentation allows the system to manage complexity by organizing protocol handling into separate, manageable units rather than a monolithic complex system

AI summary
A femtocell gateway apparatus arranged on a mobile IMS network comprises a conversion unit that when receiving a request from a terminal via a mobile network, transfers the request to a femtocell access point located in a home, reads a stream or file including at least one of video and audio, from at least one of devices connected to the femtocell access point and devices connected thereto via a home network, subjects the read stream or file to a conversion suitable for at least one of the capability of the terminal and the characteristics of the network, and outputs the stream or file converted. The output packet is then sent through a packet forwarding apparatus on the mobile network to the terminal.
