The problem – Video bandwidth congestion

  • Most video services are unicast, not broadcast
  • In other words, if N users use B bandwidth each, the total bandwidth used is N x B
  • When N is in 10s and 100s crores, the bandwidth is not sustainable
  • Even 4-5 users in a cell can cause congestion
  • Distribution does not take advantage of multicast or broadcast for live streams

The Solution – Next Gen Broadcast

  • Saankhya’s NextGen TV chipset SL400x developed in for OneMedia LLC
  • Supports NextGen an all-IP broadcast open standard (ATSC 3.x)
  • Recently adopted and being implemented in Korea and USA
  • Universal demodulator to support multiple standards

Multicast Supplement to Unicast OTT

  • Broadcast offloads live content (news, sports, popular entertainment), downloads, etc.
  • Unlimited number of users access same content in broadcast footprint
  • No pixilation, buffering or freezing – improves user experience
  • Broadcast/broadband convergence

DTT for File Casting

  • DTT Bandwidth can be used for file casting
  • Share bandwidth with Live Programs
  • Increased monetization of “spare” bandwidth from content providers

Non-real Time Push Delivery

  • MPEG Multimedia Transport (MMT) will replace MPEG-TS for broadcast/broadband
  • Apps can be developed for
    • Content selection
    • Subscription

    • Targeted ads
    • Audience measurement

File Casting Applications

  •  Carousel of most popular viral videos
  • Popular releases of content providers
    Netflix, Amazon, YouTube
  • Independent movies releases
  • Software downloads

DTM for Rural India

  •  Rural India’s predominant media consumption device is the mobile
  • Rural viewership and amount of viewing is higher (more time, less other options)
  • DTM implemented in rural India will provide broadcasters significant increase in eyeballs and TRPs
  • 1000s of LPTV and cell towers and dark fibre to Gram Panchayats can be mobilized
  • Educational content streaming will also bring tremendous social benefit

Benefits of Broadcast

  • Broadcaster – Best user experience for OTT (no buffering or freezing or pixilation); Eyeballs and ad revenue
  • Consumer – High quality streaming without using data plan
  • Wireless Operator – Network congestion offload of popular linear content
  • Advertiser- Eyeballs and reach; targeted ads
  • Government– Social development, revenue generation

Mobile TV devices evolution

  • Mobile TV ecosystem is evolving from dongles and outer cases to fully integrated chipsets and antennas.
  • Mass adoption may require business partnerships with wireless operators who influence device manufacturers
