إدراج الإعلانات من جانب الخادم للمذيعين: السيطرة من المصدر
In 2026, connected TV won the upfront for the first time. US CTV upfront commitments reached $17.73bn, edging past primetime linear’s $16.98bn, according to eMarketer. The audience and the money have moved. Yet most broadcasters still run ad insertion far downstream, deciding which ad plays, where and for whom in the CDN, or on the viewer’s device. This is the case for treating server-side ad insertion, and dynamic ad insertion more broadly, as a decision you make at the source, the head-end, not just a delivery method you outsource downstream.
أموال CTV تتحرك أسرع من تقنية الإعلانات لديك
لا يزال النمو الرئيسي يشير في اتجاه واحد. تضع eMarketer إنفاق الإعلانات على التلفاز المتصل في الولايات المتحدة عند حوالي 37.95 مليار دولار في عام 2026، بزيادة نحو 15% على أساس سنوي، و توقعات الإنفاق الإعلاني لعام 2026 الصادرة عن IAB مستخلصة من استطلاع شمل 205 من المديرين التنفيذيين في جانب الشراء، تتوقع نمو CTV بنسبة 13.8%، في المرتبة الثانية بعد وسائل التواصل الاجتماعي. الطلب على الإعلانات المستهدفة على الشاشة الكبيرة موجود.
The gap is where it gets interesting for you. In 2025, CTV captured 20.2% of the time people spent with media but only 7.7% of ad spend, per eMarketer. That’s the widest attention-to-spend gap in advertising, and one that’s closing fast. Ad-supported streaming now drives the subscriber base too: ad-supported tiers accounted for 57% of gross additions across premium SVOD services in early 2025, according to Antenna. These headline figures are US-centric, but the shift isn’t: Omdia expects global FAST revenues to climb toward $11bn by 2030, with Europe a major driver. It’s why broadcasters like CANAL+ and ITV are already moving ad control to the source.
So the money is arriving. The question is whether your platform is built to capture it, filling every ad break with the right ad creative, or to hand a share of it downstream. If you’re weighing how AVOD, FAST and hybrid models fit together first, our دليل تحقيق الدخل من محتوى OTT يمهد المشهد. يتعمق هذا المقال أكثر في الطبقة التالية: البنية التحتية لإدراج الإعلانات التي تحدد مقدار إيرادات الإعلانات التي تحتفظ بها فعليًا.
إدراج الإعلانات من جانب العميل مقابل الإدراج في المراحل اللاحقة: أين يتسرّب القرار
تتبّع ظهور إعلان ما بشكل عكسي وستجد عادةً أن القرار (أي إعلان، أي مشاهد، أي منطقة) يُتخذ في أحد مكانين. وكلاهما يعاني من التسريب.
Client-side ad insertion (CSAI) makes the call on the device. When an ad break arrives, the player fires an ad request to an ad server such as Google Ad Manager or FreeWheel, which returns the selected video ads for playback. It’s flexible and it measures well, but that separate ad request is exactly what ad blockers intercept, and on connected TVs the ad playback is fragile: buffering, failed fills, an inconsistent viewer experience. Every blocked call is ad inventory you can’t sell, and every failed fill is an ad impression you never served.
The alternative many broadcasters reach for is dynamic ad insertion at the distribution layer, handled by the CDN or a downstream partner. It survives ad blockers, but it’s rigid and costly. Ad placements live outside your control, targeting is coarse, and reacting to a live moment (a goal, an overrun, a rights restriction) means waiting for a system you don’t own to catch up.
لا تتعلق أي من المشكلتين حقًا بآليات إدراج الإعلانات. كلتاهما تتعلقان بـ حيث يتم اتخاذ القرار. إذا كنت تريد الصورة الأكمل لكيفية عمل استهداف إعلانات CTV وOTT من البداية إلى النهاية، فقد غطينا ذلك آليات إعلانات الفيديو عند الطلب والبث عبر الإنترنت بشكل منفصل. الخلاصة: كلما اقترب هذا القرار من بث الفيديو الخاص بك عند المصدر، زاد ما تتحكم به منه.
من جانب المصدر مقابل جانب CDN: أين يقع قرار الإعلان
You already hold the most valuable point in the chain: the broadcast signal at the head-end, before your video stream fans out to CDNs, apps and devices. That’s where the ad decision can sit too.
ما الذي تقوم به SCTE-35 وESAM وPOIS فعليًا
Three standards do the work here. SCTE-35 marks the ad breaks, the points in the video stream where an ad can go. ESAM (Event Signalling and Management) manages those ad placements dynamically and makes sure each one executes correctly. POIS (Placement Opportunity Information Service) holds the intelligence: where the ad breaks are, and structured data about each, from duration to timing to conditions. We’ve broken down كيف تنقل POIS وESAM التحكم في الإعلانات إلى المصدر بمزيد من العمق.
التمييز المهم: مُدمِج إعلانات من جهة CDN يُدرج محتوى الإعلان إلى المانيفست. نظام head-end يقرر ما الذي يجب أن يوضع هناك، ولمن، وفي الوقت الفعلي، ثم تترك عملية دمج الإعلانات اللاحقة تنفيذه. أداة دمج الإعلانات آلية. أما اتخاذ القرار فهو حيث تكمن الإيرادات والتحكم. لدينا منصة POIS الرئيسية يضع هذا القرار عند الإشارة، بحيث يمكنك إدراج الإعلانات أو استبدالها أو إزالتها في ثوانٍ دون الاعتماد على أنظمة مستوى التوزيع.
تخبرك الإشارات بالمكان الذي يمكن أن يذهب إليه الإعلان؛ أما تحديد ما ينتمي إلى هناك فهو النصف الآخر من اتخاذ القرار على جانب المصدر. لدينا BSG MetaDAI analyses EPG metadata and maps each programme to standard IAB categories (Sports, Travel, Food & Drink), so a campaign is matched to programme context from the start, then refined with regional or audience rules. Sports fans see one ad during a live match, families another during a kids’ show, each decided at the signal rather than guessed downstream.
الاستهداف الإقليمي والحجب من مصدر رئيسي واحد
Head-end control also solves two things downstream systems handle badly. Regional ad targeting: serve targeted ads for a local business to an urban audience and a national brand to everyone else, from a single master feed, rather than maintaining parallel video workflows. And blackout, which means enforcing rights restrictions on live content, becomes a signalling decision at source, through SCTE-224, not a scramble in the app. Swap an ad after a goal, drop a premium mid-roll or post-roll into an overrun, black out a fixture in one territory: all decided where you already control the stream.
SSAI وSGAI ومشكلة القياس التي لا يمكنك تجاهلها
نقل القرار إلى المصدر لا يحسم كيفية وصول الإعلان إلى الشاشة، وهنا ينبغي أن تكون صريحاً بشأن المقايضات بين الطرق الرئيسية لإدراج الإعلانات الديناميكية.
كيفية عمل دمج الإعلانات في إدراج الإعلانات من جانب الخادم
Server-side ad insertion (SSAI) stitches ads directly into the video stream on the server, so content and ads reach the device as one continuous single stream, the most deployed form of dynamic ad insertion. An ad stitcher splices in the selected video ads at each ad break, whether pre-roll, mid-roll or post-roll. SSAI technology beats ad blockers and holds a consistent viewer experience across devices, with no separate ad request to fail, which is why it’s the default for CTV, FAST and most live streaming.
Its cost is measurement. Because the ad is baked into the single stream, the client-side signals advertisers rely on to verify ad delivery get weaker. That’s not a small concern. In IAB research, 43% of CTV buyers said they weren’t confident where their ads actually ran. Weak measurement isn’t a technicality — it depresses what buyers will pay per ad impression.
إدراج الإعلانات الموجه من الخادم وتتبع الإعلانات من جانب العميل
This is where server-guided ad insertion (SGAI) comes in, the newest dynamic ad insertion approach. The server decides which ad plays and when; the player fetches the ad creative and handles playback, with client-side ad tracking restoring the measurement SSAI erodes. You keep the ad-block resistance and the shared, cacheable video content, and you open the door to interactive ads and richer ad formats that pure server-side ad insertion can’t carry, all without disrupting the viewer experience. The signalling behind SGAI is now standardised, through HLS Interstitials and MPEG-DASH Events, and the إرشادات تنسيق إعلانات CTV من IAB Tech Lab لشهر ديسمبر 2025 gave the formats it enables, like pause and squeezeback ads, their first cross-platform specifications. Adoption is accelerating on the back of that, though SSAI technology remains the more mature default heading into 2026.
Here’s the point that ties back to the head-end: source-side decisioning doesn’t compete with server-side ad insertion or SGAI. It sits above both. The decision about what ad belongs in an ad break can happen at your signal whether that ad is stitched server-side or guided to the player for client-side ad tracking. Get the decision layer right and you can change ad delivery strategy underneath it without rebuilding.
كيف يبدو هذا في الممارسة العملية
النظرية مرتبة. لكن البث المباشر ليس كذلك. إليك كيف يتحقق التحكم في الإعلانات من جانب المصدر في عملية نشر حقيقية.
We built Poland’s first real-time, signal-based ad replacement system for CANAL+, a major broadcaster and pay-TV provider. It runs on our POIS application: it takes the incoming video stream with its original metadata, manages the SCTE-35 markers dynamically, and outputs modified markers ready for real-time ad insertion, so ads can be substituted live, without relying on pre-scheduled ad breaks. The platform went live in December 2024 and reached full operational integration by February 2025, built in Java with a DevOps toolchain around it. You can read the دراسة حالة استبدال إعلانات CANAL+ بالكامل للتفاصيل.
The pattern that works, in our experience: don’t rebuild the video workflow in one move. Start with a pilot on a few channels or a single live event, prove the signalling end to end (marker normalisation, correction, generation at the encoder), then integrate with your encoders, ad servers and monitoring, and scale from there. It’s the same approach we take maintaining SCTE-35 marker management through ESAM for ITV, where the daily reality is keeping live signals standards-compliant under continuous monitoring, not a one-off install.
What both have in common: the hard part is rarely the protocol. It’s the seams between the encoder team emitting cues, the platform team running the signalling, and the ad-ops team owning the ad server exchange. Source-side ad insertion works when those seams are engineered deliberately.
حالة الإيرادات، وما لن تعالجه السيطرة من جانب المصدر
The commercial argument is direct. Targeting quality now drives what buyers pay: in IAB’s 2026 survey, 49% of buyers named targeting capabilities their top criterion for TV and video spend, up ten points and overtaking content quality. Better decisioning at source, whether regional, contextual or real-time, is what makes targeted ads possible at scale, and it maps straight to CPMs and the value of every ad impression.
لكننا نفضّل أن نكون صريحين بشأن الحدود، لأن المبالغة في الوعود لا تفيد أحدًا.
Source-side control won’t create advertiser demand you don’t have; it helps you capture demand more fully, not conjure it. It won’t replace client-side ad tracking; if verification matters to your buyers, you’ll still want SGAI or an OMID-based approach alongside it. And it isn’t plug-and-play: it needs integration with your encoders and ad servers, and it earns its keep on live and linear-style inventory more than on a simple post-roll or pre-roll on VOD. If your monetisation is entirely post-roll and pre-roll on demand, the case is weaker, and you should know that before you invest.
What it does do, reliably, is put the decision that determines your ad revenue back where you already control the video stream. For most broadcasters chasing the CTV shift, that’s the difference between setting the terms and accepting someone else’s.
الخلاصة
The CTV money has arrived, and it’s still arriving. What decides how much of it you keep isn’t whether you run ads – it’s where you decide them. Push ad insertion downstream and you accept coarser targeting, weaker control and a share handed to systems you don’t own. Keep the decision at the head-end, and real-time, regional, targeted ads sit where you already hold the video stream, ready to be delivered by server-side ad insertion, SGAI, or whatever comes next.

الأسئلة الشائعة
Client-side ad insertion (CSAI) inserts video ads on the viewer’s device, firing an ad request to an ad server. It’s flexible and easy to measure, but vulnerable to ad blockers and unreliable on connected TVs. Server-side ad insertion uses an ad stitcher to splice ads into the video stream, so it resists blockers and holds a consistent viewer experience across devices. The trade-off is weaker client-side measurement, which SGAI aims to restore.
Head-end ad insertion means deciding and managing ad placements at the broadcast signal itself, before your video stream reaches CDNs, apps or devices, using standards like SCTE-35 and ESAM. It lets broadcasters insert, replace or remove ads in real time, serve targeted ads regionally from a single master feed, and enforce blackouts at source, rather than depending on costly downstream ad insertion.
Not yet. Server-guided ad insertion (SGAI) restores the measurement and interactive ads that SSAI weakens, and its signalling was standardised through HLS Interstitials and MPEG-DASH Events, with IAB Tech Lab’s December 2025 CTV ad format guidelines adding specs for the formats it enables. But SSAI technology remains the more mature, widely deployed default for CTV and FAST going into 2026. Most platforms run a mix of ad insertion methods, choosing per surface rather than switching wholesale.
Indirectly. Server-side ad insertion protects ad inventory from ad blockers, but the revenue gain comes from better decisioning: real-time, regional and contextual targeting decided at source. With 49% of buyers ranking targeting as their top criterion in 2026 (IAB), stronger decisioning supports higher CPMs and more valuable ad impressions. It won’t create demand that isn’t there; it helps you capture more of the demand you have.
المعايير الثلاثة الأساسية هي SCTE-35، الذي يحدد فواصل الإعلانات في بث الفيديو؛ وESAM، الذي يدير مواضع هذه الإعلانات ديناميكياً ويحافظ على صحة الإشارات؛ وPOIS، الذي يحتفظ بذكاء تحديد المواضع. بالنسبة للتعتيم المباشر والحقوق الإقليمية، يتولى SCTE-224 معالجة السياسات. ومعاً، تتيح هذه المعايير للمذيعين إدارة إدراج الإعلانات على مستوى الإشارة بدلاً من المراحل اللاحقة.
