Having said that, the growth of ad insertion poses challenges for a number of broadcasters, pay-TV operators, content programmers, and various video providers striving to meet the diverse needs of their businesses and target audiences.<\/p>\n\n\n\n
With this being clear, let us look into the criteria differentiating SSAI vs CSAI in this article.<\/p>\n\n\n\n
<\/span>What is CSAI?<\/b><\/span><\/h2>\n\n\n\nCSAI, or Client-Side Ad Insertion, is the method employed for delivering ads to devices such as desktops, mobiles, CTVs, and gaming consoles. In this approach, the html5 video player<\/a> requests the ad server to stream an advertisement when it reaches specific ad markers in the stream or, technically known, in the manifest file (HLS\/DASH).<\/p>\n\n\n\nUpon receiving the request from the player\/device, the ad server strategically responds with the appropriate ad based on data collected from various sources, including campaigns and audience preferences.<\/p>\n\n\n\n![\"CSAI](\"https:\/\/www.vplayed.com\/blog\/wp-content\/uploads\/2022\/06\/Inner-Image-1-9-1024x625.png\")
<\/figure>\n\n\n\nCSAI functions by having the video player pause the content, and in this interim, the ad is played. Subsequently, the content or video playback resumes. In this process, the client assumes a major responsibility for reporting on the ad performance through various metrics and dimensions.<\/p>\n\n\n\n
It can support skippable, clickable, and closable ads, along with providing rich tracking and metrics for ad performance reporting. Notably, CSAI can be deployed without ad marketers. This dynamic approach allows for a comprehensive understanding of ad performance and enhances the overall effectiveness of client-side ad insertion.<\/p>\n\n\n\n
<\/span>Some of the metrics and dimensions include:<\/strong><\/span><\/h3>\n\n\n\n\n- VAST (ad metadata)<\/li>\n\n\n\n
- VMAP (ad timing)<\/li>\n\n\n\n
- VPAID\/SIMID (interactive ads)<\/li>\n\n\n\n
- OMID (viewability measurements)<\/li>\n<\/ul>\n\n\n\n\n

\n<\/div>\n\n\n\n<\/span>How Does Client-Side Ad Insertion Work?<\/b><\/span><\/h2>\n\n\n\nIn this section, let us look into the processes of how CSAI (Client-Side Ad Insertion) operates.<\/span><\/p>\n\n\n\n![\"How](\"https:\/\/www.vplayed.com\/blog\/wp-content\/uploads\/2022\/06\/Inner-Image-3-4-1024x625.png\")
<\/figure>\n\n\n\n\n- At the onset, the player downloads the file from the CDN<\/a> before video playback commences. For example, in a pre-roll video ad<\/a> scenario, the ad initiates before the video content begins.<\/li>\n\n\n\n
- When the video player reaches an ad marker, it initiates an API call to the ad server, requesting an ad for playback.<\/li>\n\n\n\n
- Typically, the ad insertion server responds with a VAST XML that includes data about the ad, the ad’s media, and tracking information.<\/li>\n\n\n\n
- The video player uses the VAST tag to initiate and execute the ad playback, thereby ensuring seamless integration within the content flow.<\/li>\n\n\n\n
- Upon the conclusion of the ad, the video player resumes the video stream, maintaining a smooth transition for the viewer.<\/li>\n\n\n\n
- Streaming platforms commonly integrate their video players with SDK support offered by third-party ad services, with the video CMS system<\/a> serving as the central hub for configuring these integrations and managing ad policies.<\/li>\n\n\n\n
- SDKs actively monitor the position of the ad playback, completion rates, errors, etc., and recurrently report this data back to servers, ensuring complete tracking and analytics.<\/li>\n<\/ul>\n\n\n\n

This method stands in stark contrast to the workings of CSAI.<\/p>\n\n\n\n![\"What](\"https:\/\/www.vplayed.com\/blog\/wp-content\/uploads\/2022\/06\/SSAI-inner-image-1024x518.png\")
<\/figure>\n\n\n\nNow, let us explore the merits and demerits of SSAI in the sections that follow. One key advantage lies in the fact that the client no longer initiates server calls, highlighting the challenge of blocking ads inserted using SSAI.<\/p>\n\n\n\n
Adding to its prowess, SSAI’s functionality comes to the forefront when the sent request includes viewer data necessary for selecting a personalized ad.<\/p>\n\n\n\n
In response, a 3rd party ad server promptly delivers an advertorial to the SSAI module. This dynamic nature showcases the enhanced capabilities of server-side ad insertion (SSAI).<\/p>\n\n\n\n
<\/span>How Does Server-Side Ad Insertion Work?<\/b><\/span><\/h3>\n\n\n\nServer-side ad insertion involves a combination of various individual functionalities, constituting a more comprehensive architecture. It commences with manifest manipulation, ad server communication, and ad bitrate with resolution normalization.<\/span><\/p>\n\n\n\n![\"How](\"https:\/\/www.vplayed.com\/blog\/wp-content\/uploads\/2022\/06\/Inner-image-4-3-1024x625.png\")
<\/figure>\n\n\n\nManifest manipulation revolves around personalizing the video experience for each viewer when a stream is requested with video and audio segments. This process is accompanied by a manifest file that acts as a playlist, controlling the playback order.<\/p>\n\n\n\n
Secondly, ad servers play a crucial role in storing and serving advertisements on online web pages. The communication with ad servers is facilitated through advertisement trafficking, providing real time analytics<\/a> data into ad performance.<\/p>\n\n\n\nAs we go deep into the insights related to video bitrate, it is essential to understand that bitrate represents the number of bits of video information transmitted per second, measured in kilobits per second or megabits per second.<\/p>\n\n\n\n
Moreover, when compressing a video, the video compression software must be directed not to exceed a certain bitrate. This ensures efficient transmission and playback.<\/p>\n\n\n\n
Furthermore, video resolution significantly influences what the user sees. Most video players automatically adjust themselves based on the viewing window or device’s screen resolution.<\/p>\n\n\n\n
All these processes occur within the server-side ad insertion architecture before presenting a manifest to clients. SSAI, also known as dynamic ad insertion or ad stitching, seamlessly integrates the ad media into the video stream, eliminating the need for server calls to receive ads.<\/p>\n\n\n\n
