摘要： A framework is described that may provide service level differentiation in IPTV delivery systems based on program content for any given television channel/programming. For example, for the same TV channel, different service levels are offered to individual subscribers. In one embodiment service levels are provided by varying the number and duration of commercials or the amount of display space afforded to commercials, value-added content and/or entertainment content in a particular channel. Accordingly, the embodiments allow service providers flexibility to provide IPTV advertisement and value-added content services. This service differentiation may attract different levels of subscribers, increasing the penetration ratio of IPTV services, facilitate the delivery of effective advertisements to target subscribers, and/or increase revenue. For example, some subscribers will pay more money to watch TV with fewer ads and more value-added content, while others may be agreeable to watching more ads if they can receive TV for less money.
摘要翻译：描述了可以基于用于任何给定电视频道/节目的节目内容在IPTV传送系统中提供服务水平区分的框架。例如，对于同一个电视频道，为各个用户提供不同的服务级别。在一个实施例中，通过改变广告的数量和持续时间或提供给特定频道中广告片，增值内容和/或娱乐内容的显示空间量来提供服务等级。相应地，实施例允许服务提供商灵活地提供IPTV广告和增值内容服务。这种服务差异化可能吸引不同级别的用户，提高IPTV服务的普及率，促进有效广告向目标用户的传递和/或增加收入。例如，有些订阅者会花更多的钱观看电视，广告和附加内容越来越少，而其他人则可能愿意收看更多的广告，只要他们能够以更少的钱接收电视节目。

摘要： According to one example embodiment the placement of video distribution servers and acquisition servers in a live television IPTV network is considered to be a separate process This process may be based, for example, on historical data, number of subscribers, subscribers service quality, some video distribution servers may be selectively placed closer to the subscribers, i e, at some central offices or intermediate offices, instead of at the video hub office These local video distribution servers (those video distribution servers not located at video hub office) may selectively receive popular TV channel streams just like regular video subscribers based on the multicasting protocol from the acquisition server Whenever a subscriber wants to switch to a channel (or recover packet loss for an on¬ going channel), if the channel is on the popular channel list, the service may be accomplished by the local video distribution servers.
摘要翻译：根据一个示例性实施例，视频分配服务器和采集服务器在实况电视IPTV网络中的布置被认为是单独的过程。该过程可以基于例如历史数据，订户数量，订户服务质量，一些视频分配服务器可以被选择性地放置在更靠近订户的位置，即在一些中心局或中间局而不是在视频中心局。这些本地视频分发服务器（那些不在视频中心局的视频分配服务器）可以选择性地接收流行的电视基于来自采集服务器的多播协议的常规视频订户的通道流每当用户想切换到信道（或恢复正在进行的信道的分组丢失）时，如果该频道在流行频道列表上，则服务可以由本地视频分发服务器完成。
