I also agree with Mr.Futomi's comment. Hyun's use cases seems much similiar to R7 cases, now. Because " live information" or "live contents" terminology is appeared in motivation part. As well, in gap analysis, live information want to include video streaming besides of headline news, weather, stock info, etc. But there is no description in use case for video streaming as a live information. So, as Futomi's mentioning, only if current suggestion are stock, weather and news use cases, there is not differential point with R7. But, If additional use case for video streaming is suggested, it can be a good example of use case. Otherwise, if Hyun want to expand for R7, R7 can be renamed with other title. And it covers notifications and streaming service from server.

As her turn comes up, she goes to the teller with the next investment plan for the money from her savings account. >> >> [Live news feeding] >> >> Michael woke up late in the morning and did not have time to check the morning news. On his way to his office, he sees the digital signage display installed on the exterior side of the bus. The display shows weather forecast, headline news, local news, and various events in form of a simplified text. >> In the subway train, Michael watch the signage display installed inside the train which shows the news video streaming of the regular broadcast in the morning rush hour. Michael can get live news and information from various signage devices on his way to his office. >> >> >> Motivation >> >> Digital signage can use to provide live contents such as news, weather, and financial report. The importance of these contents tends to be inversely proportional to the elapse of time. Therefore, it is very important to retrieve live information to be displayed in real-time. >> >> >> Gap Analysis >> >> Live information in text-style such as weather broadcast and stock information can be retrieved via WebSocket API(http://www.w3.org/TR/websockets/) and Server-Sent Events(http://www.w3.org/TR/eventsource/). >> For live video streaming, HTML5 video tag can be used. HTML5 video tag does not specify any particular real-time streaming protocol, but it allows the use of any protocols such as RTSP(Real-time Streaming Protocol, RFC2326), HLS(HTTP Live Streaming, <https://developer.apple.com/library/ios/#documentation/NetworkingInternet/Conceptual/StreamingMediaGuide/StreamingMediaGuide.pdf> https://developer.apple.com/library/ios/#documentation/NetworkingInternet/Conceptual/StreamingMediaGuide/StreamingMediaGuide.pdf), and MPEG-DASH. >> >> >> >> >> >> >> > > -- > Newphoria Corporation > Chief Technology Officer > Futomi Hatano > -- > futomi.hatano@newphoria.co.jp > http://www.newphoria.co.jp/ > >
