  31. Protection techniques • Standards compliant FEC (Forward Error Correction) • SMPTE2022-1 for JPEG2000 and ASI transport • SMPTE2022-5 for linear high rate transport • Integrated SIPS (Streaming Intelligent Packet Switching) - network protection via diverse routing • RTP layer, packet based ‘healing’ • EPP (Encoder Partner Protection) - hardware protection • Protection for hardware failures in 1+1 configuration • LDO (Launch Delay Offset) – SIPS enhancement • Protection for simultaneous loss on both Network streams

  32. Forward Error Correction (FEC) • Video transmission via RTP/UDP/IP is best effort • Packets can get lost • One solution is to sent additional packets to aid in recovery • The problem becomes one of • Video input rate • Network Performance • Available Bandwidth • Desired packet recovery performance

  33. Forward Error Correction • FEC recovers lost packet in real-time on the RX side • Data packets are arranged in two-dimensional matrix • XOR checksum is used to generate redundancy FEC packets • XOR is like addition without using carry digits • The cost is higher overhead and latency • FEC for Transport Stream on IP: SMPTE 2022-1

  34. 1 packet is ~10.000 bits 01100101001 1 2 3 4 5 .. L ----1----- L+1 2L ----1----- ----0----- ----0----- ----1----- ----0----- L*D XOR XOR F F F F F F F ----1----- SMPTE 2022-1 FEC • 1D column only FEC • May correct one (1) lost packet in each row • It is possible to correct a complete row (L packets) L Columns Media datagram Column FEC datagram # F D Rows

  35. L Columns 1 2 3 4 5 .. L R L+1 2L R XOR R C D Rows R R R R L*D R XOR C C C C C C C FEC for each Row improves Protection • 2D column and row FEC increases performance • General FEC constraints • Increased burst protection result in added delay • Reduced overhead require added delay Media Datagram Column FEC Datagram Row FEC Datagram

  36. Transport - IP • FEC for IPLR attenuation generates significant overhead anywhere up to 50% • Question to ask is: “Is FEC a requirement in contribution networks?” • IP networks are usually carefully managed • If packets are being lost, then corrective action is required • FEC then is an insurance against the unknown

  37. Nevion’s SIPS technology:Next generation solution for redundancy • Streaming Intelligent Protection Switching (SIPS) • Fundamental building block for next generation managed video services • Slipless switching at IP layer • Does not affect services - no outages, no affection of downstream path • Works with multiple IP path configurations - dual and single • 1+1 edge equipment redundancy can be added to further increase availability • Common feature in the VS902/VS906 suite SIPS provides unparalleled service levels to broadcasters – even better than traditional video networks

Video-layer service protection- Dual network interfaces SIPSTM Video in(ASI, SDI) Video out(ASI, SDI) • Protectionswitching done by Decoder • Sliplessswitching is provided by NevionsStreaming Intelligent ProtectionSwitching (SIPSTM) • Reduncancyprovided in case of: • Link failure in the core • Equipmentfailure in the core • Redundancyprovided by corerouters and switches • Link failurebetweenEncoder/Decoder and IP edgerouter • Noredundancyprovided in case of: • Encoder/Decoderequipmentfailure • Video source missing • Errors in video source signal

  40. Ventura VS902 architectureSIPS and Input Protection Switching

  41. Seamless Switching • Media is replicated and encapsulated over dual networks • Network routed over diverse path • Receivers buffers and time aligns packets from diverse network • Receiver selects best packet to provide error/glitch free switching Optimum Stream Look ahead switch Buffer Buffer Stream Analysis

  42. SIPS - Pros • Can be used for any media • Protects for the most common Link failures • Switch event is seamless (not detectable or measurable) • Protection capability is up and running with <1 second of link restoration and in the millisecond range on restoration of packet flows.

  43. SIPS - Cons • If diverse path is not guaranteed, Simultaneous loss of both feeds results in unrecoverable event. • Double bandwidth utilization • No protection for hardware failures

  44. SIPS-LDO – Solution to lack of diverse path • Recent broadcast audio application in Europe • Contribution Audio (National Radio Network) over IP • Ethernet over SDH infrastructure • No control over infrastructure • Worried over the 50ms APS gap • FEC cannot bridge APS gaps • Leveraged SIPS with Launch Delay Offset

  45. Launch Delay Offset • Encoder launches primary stream immediately. • Launches secondary stream delayed by 60ms to cover 50ms APS • In an APS event, the secondary stream arrives outside of the 50ms switchover • SIPS selects the best packet for perfect switch

  46. SIPS-EPP – Solution for Hardware Protection • For a 1+1 hardware protection with perfect switching • Inter-connect two SIPS capable encoders at transmitter

  47. Encoder Partner Protection • For a 1+1 hardware protection with perfect switching • Inter-connect two SIPS capable encoders at transmitter • Video transmitted on Master-Primary and Slave-Secondary • Receivers are independent and operate on SIPS from Master/Slave flows

  48. EPP Operation VS902 (Master Tx) SIPS VS902 Rx Output Media Input Media VS902 (Slave Tx) VS902 Rx SIPS Master A feed Physical connection Master B feed

  49. EPP Operation – SSRC implementation VS902 (Master Tx) SIPS VS902 Rx Output Media Input Media VS902 (Slave Tx) VS902 Rx SIPS Master A feed Cross link failure Master input loss Master card fail Master B feed

  50. Encoder Partner Protection • The types of faults that will result in a perfect switch are: • Failure to input on the Slave, • Failure of the Slave, • Failure of any link or network node. • The types of faults that will result in a non-perfect switch are: • Failure to input on the Master, • Failure of the Master. • Failure of cross strap, the Slave will automatically output from its internal engine. • The receiver will detect non-coherence in the primary and secondary feeds but maintains lock on the primary stream.
