Our Potential Products. Back to Main Page
We need to provide short, medium, and long term products. For each product, we need to estimate its complexity (time to market), potential customers, competing products, our edges, links to our software design, hardware, etc.
Short Term 0.5 - 2 Years
Product S1: Mobile TV Base Station for Unlicensed Use
Our first product is a low-cost workstation that allows small-scale deployment using unlicensed spectrum. Potential customers include universities, companies, communities, museums, and zoos, which want to efficiently (in terms of costs) deliver video streams to users within small geographical areas. For example, museums and zoos can provide visually-enhanced guided tours using our base stations without huge capital investments such as licensing a spectrum.
This product is similar to our MM08 mobile TV testbed. Additional enhancements include: (i) mechanisms to query white space database, (ii) hardware to sense co-channel interference (need to check the FCC standards), and (iii) integration with some mobile TV capable devices, i.e., implementing a client program. Using a 5MHz channel within a short broadcast range, our base station can transmit 40 QVGA programs, where each program has a coding rate of 512 kbps. Concurrently reading and encapsulating 40 programs should be feasible to recent quad-core CPUs and multi-Gigabit disks.
We are not aware of any base stations that supports broadcasting over white space channels yet.
Product S2: VideoCast User Generated Content over Mobile TV Networks
While YouTube has been very successful on PC users, it is less popular on mobile devices for two reasons. First, mobile devices have low-speed wireless links. For example, existing HSDPA networks have a theoretical maximum bandwidth of 14 Mbps, which is shared among all users in the same cell. Second, mobile devices have small screens, which make browsing and searching for clips difficult. Effectively searching videos is important for user generated databases like YouTube due to the large number (millions) of videos in them.
To provider better user experiences,
To address the bandwidth issue, we may use mobile TV networks to broadcast the most demanded video to many u
