Dual-Band Hybrid Satellite System
We believe that mobile satellite broadband service requires the bandwidth efficiency provided by Ka band satellite and spot beam based High Throughput Satellites, or HTS. However, limited Asia-Pacific coverage area of Ka HTS systems restrict the use of a pure Ka band system. Our design of dual Ka/Ku band satellite terminal allow independent acquisition of Ka and Ku band satellites at different orbital positions thus maximizing the utilization of satellite bandwidth.
The current mainstream video compression format is H.264, also known as MPEG-4 Advanced Video Coding, or AVC. It is widely used in Blu-ray discs, online videos, web software, and HDTV broadcasts terrestrially and over cable and satellite.
H.265, also known as High Efficiency Video Coding, is a newly developed video compression standard designed to replace H.264. It is capable of delivering H.264 video quality at half the bit rate. H.265 has several significant advantages over H.264, including better compression, higher image quality, and lower bandwidth usage.
We incorporate hardware-based, real-time technology that transcodes content from multiple streaming or broadcast input forms. We convert the content into H.265-encoded Internet protocol, or IP, streams, which reduces the amount of bandwidth required while enhancing the quality of the content. By deploying real- time transcoding technology in its ground and airborne systems, we enable live TV and video streaming in an IP format that optimizes satellite bandwidth utilization and achieves cost-effective content delivery.
Satellite Link Acceleration
The most common transmission control protocols, or TCPs, used in the Internet have been designed with terrestrial wired networks in mind. TCPs do not perform well in long-delay satellite environment and may cause bad user experience in web surfing and Internet access.
Our satellite link acceleration technology improves TCP/IP-based data transmission over a satellite system through compression, deduplication, caching, latency optimization, packet aggregation, and cross-layer enhancement. This technology includes end-to-end software in airborne system and ground server for cost effective application accelerator and optimization of live TV and video streaming. This combination of technologies makes airborne Web access and contents access feel close to fiber at home.
AirCinema incorporates projector-based H.265 steaming technology onboard an aircraft. We are optimizing this projector system technology for in-flight viewing and entertainment purposes by utilizing auto focusing, zooming, and alignment, as well as dynamic brightness control. Passengers will be able to use the AirCinema directional audio system to enjoy onboard music and content without the need for a separate headset.
