異地異時觀看(Asynchronous viewing over a distance)
若考慮到兩地的觀眾有各自的時間行程,日常生活步調,甚至身處不同的時區,這或許是最可行的情境。在這種情境,社會電視應用可以錄下或分享節目內容,讓使用者了解社群成員的收視習慣。讓使用者對內容下註解,或錄下與觀看內容時的互動。紀錄每個人的行為,在下一次取用內容的時候,提供一些個人化的內容,促進非同時的傳播。可以是字幕,或是視覺標記,文字或語音的註解,等等。
This a feasible scenario if we consider that distance viewers might have very different time-schedules, patterns of daily life activities, or even live in distant time zones. Then, the probability of synchronous co-viewing is rather limited. In this case, a social TV system could record and share shows and viewing habits with the members of the social circle. In addition, a social TV system should allow annotation of content and recording of interactions, such as pausing, skipping, replaying and content browsing. In this way, each time a particular TV programme is accessed, a trace is kept, which is exploited at the next access, in order to personalise the content and most notably to provide a motivation for asynchronous communication. This could be rather subtle, such as visual annotation of the content highlights, or could be more explicit such as audio and text comments.
