  1. IP Over DVBSystem Requirements Issues for SI-DAT to Consider Narisa N. Y. Chu Georges Martinez David Garrec 23 July, 2001

  2. Insert IP stream un-related to Program Insert IP stream un-related to Program or IP stream related to Local Program Insert IP stream related to Program Insert IP stream related to Program IP Over DVB Delivery Program Content Provider Satellite Operator Cable Operator Terrestrial Broadcast Operator

  3. IP Over DVB Requirements (1) Video related IP vs. Generic IP • IP data related to program content • Program Content Provider generated IP stream • IP Stream with Digital Program Insertion by Operators • IP stream is conveniently encapsulated with the video and audio components • IP data un-related to program content • Operator becomes ISP : DVB-ISP • IP stream can carry in conjunction with different video and audio streams, or can be in stand-alone MPEG streams • IP services localized to the deployed networks

  4. IP Over DVB Requirements (2) • Characteristics of Satellite, Cable, Terrestrial Delivery Networks • Coverage – mix of DVB and IP service load • Penetration – Delivery of IP service via the most predominant network • Architecture – Consider all network elements including HE, Remux, Server, and STB • Services - related to the delivery network • Network Requirements • Static or dynamic network configuration management • Remux – signalling, bandwidth management, video and IP traffic optimization • Mapping of multiple IP / MAC addresses • Refreshing rate – performance requirement • for IP related information • reliability

  5. IP Over DVB Requirements (3) • Terminal Requirements • Level of required Interactivity • Assumed network knowledge • Learns the IP platform (IP server profiles, location) configurations • Maintains preset NIT information • Identifies mandatory vs. optional information • Accesses to IP addresses quickly and efficiently • Supports many Multicast addresses • Cost effectiveness • Content • Native DVB • Video • Audio • Private Data • Native IP • Internet Content: web browser, E-mail, news, announcements, etc. • Streaming Video

  6. Insert IP stream un-related to Program Insert IP stream un-related to Program or IP stream related to Local Program Insert IP stream related to Program Insert IP stream related to Program IP Over DVB Delivery Issues Summary Program Content Provider (Typically uses Private Data Component in PMT to signal IP data) Satellite Operator • May use IMT to signal IP data • Concerns about NIT integrity Cable Operator • Uses PMT • Uses MAC Address List Descriptor • Maintains MPEG integrity Terrestrial Broadcast Operator (Uses PMT and MAC List Descriptor?)

  7. Guiding System Questions • Video vs. Data Delivery Service • Balance of Video versus IP Traffic • Optimization • Priority • Subscriber Acceptance • MPEG vs. IP Cross-pollination • Latency • Interactivity • Compression vs. Packetization • Multicast, Simulcast, Point-to-point • Terminal Complexity Impact • Network Complexity Impact
