“Does TTI need Hybrid Delivery?”

Bev Marks writes: “I have a short story emanating from the UK but, I believe, with issues that TISA should consider for all markets. Recently T-Mobile announced a significant change in their tariff for data download to mobile phones; indeed a “data cap” has been introduced and this has really woken up the radio futurologists. Their calculation about the cost of data to mobile phones has some interesting lessons for us in the TTI domain. According to my calculations we only require about 1/8 of the data that radio listening needs, for continuous TTI services. Nevertheless all this points more strongly, in my eyes, to the need for TISA to welcome the broadcast industries current enthusiasm for radio to be delivered as a “hybrid solution” – with both broadcast and IP technologies being used to provide the end-user experience – may I propose that this also applies to

TTI data services.. Not least, because TTI has a ubiquitous service delivery need that as networks roll out we can achieve by mixing both delivery methods, just as long as client devices are fed with service following meta data and are agile in finding the required information.

I suggest reading the following blogs, in this order:

I think we all agree that radio’s digital delivery platform(s) are required for next generation TTI services (as witnessed by TISA work on Adaptation layers for DAB and HD Radio); more recently the utility that IP delivered TTI services can offer has been recognised within TISA.

Both represent challenges for service provision and product development, so developing a TISA position for both – in parallel – and being really ready makes sense to me.
