hd sd mpeg 2 4 encoder with sdi hdsdi input
HD/SD MPEG-2/4 Encoder with SDI/HDSDI input
  • Encodes up to 2 HD or 4 SD channels per blade

- Dual HD encoder offers HDSDI with the addition of AES unbalanced audio inputs

- SD encoder supports 4 services per blade and is license key upgradeable to 2 x HD

- Imminent software option will provide premium video quality in exchange for a 50% reduction in density (eg. 1HD or 2SD per card)

  • Rate Control Modes:
    • Constant Bit Rate (CBR)
    • Variable Bit Rate (VBR)
    • Capped VBR (CVBR)
    • Statistical Multiplexing (in future release)
  • Adjustable GOP structure
  • External clock reference (Frame sync)
  • 2 encoded stereo audio pairs per video

Available Soon!

  • Significant advantages since it will handle COMPONENT video as well as composite!
  • Available Q4 2012

the problems with composite
The problems with Composite

F(csc) = 4.43361875 MHz

  • 1. Analog Broadcast studio, no problems since high quality rubidium or other
  • accurate oscillator used.
  • 2. Digital distribution to a professional IRD. This depends upon the following;
    • Where the 27MHz MPEG clock comes from
    • This may be internally generated (poor)
    • Derived from PCR (locked to clock source in the encoder) – potentially better
    • Derived from a high stability external source (frame sync input) – best.
  • 3. Consumer or pro-sumer set top box. Almost certainly internally generated from a
  • low-cost crystal oscillator. Poor.

composite and component video
Composite and component video

With digital distribution of analogue signals, the best solution is to keep the

chrominance and luminance signals separate and AVOID using composite!

Every output card has

A multiplexer for

maximum flexibility!

the nms
The NMS
  • Compression vendors will usually want to sell an NMS with their system
    • It will be their own NMS
    • It will be proprietary and designed to work with their equipment only
    • If third party equipment is supported, it will only be for limited products that
    • are needed to make their portfolio complete
    • It can provide vendor lock-in and restrict the equipment choices you
    • can make in the future!

Appear TV

the nms1
The NMS
  • Appear TV takes a different approach.
    • We try and build redundancy options into our chassis so that an NMS
    • becomes optional. This can reduce system complexity and cost
    • When an NMS is required, we provide a choice of open NMS platforms to
    • match any price and functionality requirement that are equipment vendor
    • agnostic
    • Appear TV can provide leading NMS solutions, when they are needed, using
    • Partners who have integrated our solutions. This approach avoids vendor lock-in!

Appear TV

protecting the distribution network
Protecting the distribution network
  • For cable, the distribution mechanism is almost always over IP
  • Redundant networks, supporting video and broadband / internet services
  • Video services delivered efficiently via RTP over UDP multicasts
  • Transient network disturbances provide the biggest risk of QOS affecting issues
  • Typically, QOS is protected by adding SMPTE2022 FEC
  • Only one delivery network is used at any one time.
    • FEC overheads can be significant (40% or more of total video traffic)
    • Still not effective in coping with long duration burst errors
  • Appear TV can of course provide the same solution,
  • ….but we also have a better way……

Appear TV

protecting the distribution network1
Protecting the distribution network
  • What if it was possible to;
    • Make an edge device that monitored the traffic arriving via both the A
    • and B networks simultaneously
    • Align and take IP packets from either network, seamlessly, to
    • re-construct the output from both networks
    • You would have a seamless solution using both networks to provide
    • 100% FEC without having to add SMPTE 2022 FEC at all!
    • The new Appear TV seamless IP switch delivers all of these features!

qam modulator card
QAM modulator card

QAM Output

  • Up to 250 services per module
  • Multiplexing on each QAM frequency
  • PSI/SI re-generation
qam modulation 4ru option
QAM modulation: 4RU option
  • Adds:
  • More space for future expansion
  • Hot swap replacement of all modules, including PSUs and fans
  • Dual redundant PSUs

Notice the example if for an RF modulator card. We can provide

A range of analogue video modulators and FM radio modulators as well!

other key redundancy options
Other key redundancy options
  • You can nominate an input to act as a back-up.
  • For example, if an IP input fails, use the satellite input as back-up.
  • Or use a DTT input to back up a satellite feed etc.
  • This is the INPUT PORT redundancy feature.
  • The same concept can be used for SERVICE LEVEL redundancy where incoming transport
  • streams are different
