Overview
Product description
BLANKOM IGS-924 and IGS-924A receive 24 RF multiplexes for IPTV headends. Choose IGS-924A for Dynamic PMT and EPG/EIT in up to 128 SPTS; it has no MPTS IP output.
The standard IGS-924 provides up to 1024 SPTS in total, with 512 per DATA port, or selectable MPTS output. Confirm the standard model’s MPTS limit for the supplied revision. The IGS-924A provides up to 64 SPTS per DATA port with Dynamic PMT and EIT programme-guide handling.
Both satellite models support DVB-S/S2/S2X reception, BISS descrambling and web management in a 19-inch, 1U chassis. Single PSU is standard; redundant power is optional. Separate data sheets for IGS-924 and IGS-924A are available below.
24-Tuner DVB to IP Gateway: IGS-924 / IGS-924A
The BLANKOM IGS-924 family converts selected services from 24 RF multiplexes to IP for professional headend networks. The standard IGS-924 and advanced IGS-924A use different output profiles; the A model is not a like-for-like replacement for every standard-model mode.
IGS-924A: Dynamic PMT + EPG/EIT
Dynamic PMT: Tracks changes in the incoming Programme Map Table, supporting selected services whose component or PID assignments change.
EPG / EIT demultiplexing: Demultiplexes the relevant Event Information Table data and carries programme-guide information with selected SPTS services for compatible IPTV receivers.
Up to 128 SPTS total: 64 on DATA1 + 64 on DATA2. MPTS IP output: NOT SUPPORTED.
The A model is specialised for SPTS-based IPTV. Do not apply the standard model’s SPTS/MPTS limits or output modes to it.

¹ A-model values refer to the documented 2026 IGS-900A/IGS-924A revision: 128 SPTS total (64 per DATA port), Dynamic PMT and EIT/EPG demultiplexing; no MPTS IP output. A-model capacities and software features must not be assumed for C/S variants. A-model links open their shared family product pages.
² Standard-model output limits vary across published revisions. Confirm the IGS-900 SPTS/MPTS limits and the IGS-924 MPTS limit for the hardware and firmware being ordered. “Not specified” does not mean “not supported”.
SPTS = Single Program Transport Stream; MPTS = Multi Program Transport Stream. Tuner count is not TV channel count. Stream counts remain subject to available services and bitrate limits. IGS-700/84 capacities are the sum of two independent modules, not a shared pool.
CAM-based reception requires compatible professional CAMs and valid service authorisation; CI+ is not supported by IGS-700/84. EIT remultiplexing and EIT demultiplexing into individual SPTS are different functions. Optional redundant PSU does not imply hot-swap or a DC input option.

Engineering questions
16 questions answered by the people who commission these unitsFAQ (Frequently Asked Questions)
What is the difference between IGS-924 and IGS-924A?
Both satellite models have 24 DVB-S/S2/S2X tuners. The standard IGS-924 offers up to 1024 SPTS in total, with 512 per DATA port. MPTS is a selectable alternative; confirm its limit for the supplied revision. The IGS-924A adds documented Dynamic PMT and EPG/EIT demultiplexing functions but uses a different output profile: up to 128 SPTS total, 64 per DATA port, with no MPTS IP output. Select by the required functions and output format, not by the A suffix alone.
What does Dynamic PMT support do in the IGS-924A?
Tracks changes in the incoming Programme Map Table, supporting selected services whose component or PID assignments change. This is relevant when a broadcaster changes the components of a selected service, including regional-service arrangements. It is not a guarantee of interruption-free switching under every broadcast condition.
Can the IGS-924A carry EPG information with individual SPTS channels?
Yes. EIT demultiplexing extracts the relevant broadcast programme-guide information and inserts it into the selected SPTS streams. Compatible IPTV receivers or middleware can then use the received EIT data. Confirm that the source supplies suitable EIT and that the receiving system supports it.
Does EIT demultiplexing create a new EPG or guarantee the same guide on every receiver?
The documented function is to carry programme-guide data from the received broadcast, not to create an independent programme schedule. EPG display depends on the available source data, receiver/middleware support and delivery configuration. Verify the intended receiving system during commissioning.
Does the IGS-924A support MPTS IP output?
No. IGS-924A does not support MPTS IP output. Its IP output is up to 128 SPTS in total, allocated as 64 on DATA1 and 64 on DATA2. For a project requiring MPTS over IP, review the standard IGS-924 and confirm its output limit and operating mode.
How many IP streams can each model deliver?
The standard IGS-924 provides up to 1024 SPTS in total, with 512 per DATA port. MPTS is a selectable alternative; confirm its limit for the supplied revision. The IGS-924A provides 128 SPTS maximum in total: 64 + 64. The A-model specification also states up to 850 Mbps per DATA port. Stream count and bitrate are separate constraints; confirm the actual service mix and simultaneous loading.
Does 24 tuners mean only 24 television channels?
No. A tuner receives an RF multiplex, such as a satellite transponder, which can contain several TV and radio services. The usable programme count depends on the received services, selected streams, aggregate bitrate and the output capacity of the ordered model.
How do the IGS-924, IGS-924A, IGS-924C and IGS-924S reception variants differ?
The family uses 24 RF tuner inputs. IGS-924 and IGS-924A are DVB-S/S2/S2X satellite models. IGS-924C is the DVB-C/T/T2/ISDB-T reception variant, and IGS-924S is the ATSC variant. These are hardware/configuration choices; do not assume the A model’s EPG functions or stream limits apply to C or S variants.
Which IP protocols are supported, and does the A model add SRT or HLS?
The documented IP output protocols for these models are UDP, RTP and RTSP, with unicast and multicast delivery. The A-model distinction is Dynamic PMT, EIT/EPG handling and the 128-SPTS output profile; the cited A-model data sheet does not specify SRT or HLS output. Confirm any additional protocol requirement separately.
Can the gateway receive encrypted services, and are CI/CAM slots fitted?
These models support FTA reception and embedded BISS descrambling for supported, authorised services. The A-model specification identifies BISS Mode 1 and Mode E. No CI/CAM slots are fitted. CAM-based pay-TV reception requires an appropriate CI-equipped gateway and the required access rights.
What PID, PCR and PSI/SI processing is available?
The standard model supports PID filtering/remapping, PCR adjustment and PSI/SI rebuilding/editing in supported modes. The A-model specification also lists CA/null-packet filtering and AIT handling. Confirm the required combination for the supplied firmware. PCR timestamp adjustment must not be described as eliminating IP-network jitter.
What is AIT carriage on the IGS-924A?
The A model supports AIT selection and carriage with selected SPTS; its v1.4 documentation also describes adding external AIT URIs. Application behaviour depends on the receiving platform and the referenced application; AIT carriage alone is not a universal compatibility guarantee.
How do the ASI outputs and USB functions differ from MPTS IP streaming?
The IGS-924A has two ASI outputs selectable from a direct tuner TS or an SPTS, plus USB TS recording/playback and information-channel streaming. An ASI connector carrying a tuner transport stream does not mean the A model supports MPTS over IP. The standard IGS-924 has USB TS playback and two ASI outputs whose routing depends on operating mode.
Does the IGS-924A support DVB-T/T2 multistream carried over DVB-S2X?
No. The documented A-model design does not support DVB-T/T2 over DVB-S2X multistreaming. Treat this as a separate requirement from ordinary DVB-S/S2/S2X reception and verify the selected hardware before ordering.
How are the models managed remotely?
Configuration and firmware maintenance use Web NMS / Web GUI. The A model has a dedicated 100Base-T management interface. SNMP is not specified in the data sheets used for this page; request confirmation rather than assuming it is included.
Is redundant power supplied as standard, and which data sheet should I use?
Single PSU is standard; redundant power is optional – please enquire. Hot-swap or DC capability must not be assumed from the word redundant. Use the separate IGS-924 Data Sheet for the standard model and IGS-924A Data Sheet for the A model in the Downloads section. State the reception standard, stream count, bitrate, EPG requirements and PSU option in your enquiry.
