35、document. Introduction SA1 has summarized service requirements in TS 22.101 13, clause 32 for TV Enhancements. According to TS 22.101 13, clause 32.1, “3GPP enhancement for TV service support is a feature whereby 3GPP networks can provide unicast and broadcast transport, referred to as “TV transport

36、 services“, to support distribution of TV programs. TV transport services can support the three types of TV services Free-to-air (FTA), Free-to-view (FTV), and Subscribed services. Each type of TV service has different requirements in order to meet regulatory obligations and public service and comme

37、rcial broadcasters requirements regarding content distribution, hence many requirements captured below are optional to implement depending on the type of TV transport services an MNO chooses to offer.“ There is interest for the TV industry to be able to deliver broadcast television (TV services) to

38、connected consumer devices (smartphones, tablets and TVs) anywhere, by using cellular networks. Audio/Video content is already a significant and growing traffic type. There is an opportunity to leverage the support for this content, and 3GPP delivery methods such as eMBMS, to provide TV broadcast an

39、d on-the-go TV/video services: - There is an interest from Over-the-top (OTT) TV/video service providers to be able to reach their customers regardless of location, and available access technology, particularly when the consumers have cellular access but not access to a broadcast TV signal (if that

40、signal exists at all). - There may be opportunities in the near future for LTE-based cellular TV broadcast services, in particular, the free-to-air TV service in some regions of Europe.
