Ad Insertion is a very important part of many video delivery systems because of the monetization aspect—it generates revenue! With Over-The-Top OTT video delivery on the internet, the holy grail of advertisement is finally achievable—it is technically possible to send individual, personalized ads to each viewer.

This paper provides an overview of such systems, showing how a traditional ad-insertion workflow at the programmer side can be used as a basis for an OTT system. We also show some other uses for the ad insertion infrastructure for program delimitation and comment on the importance of frame accuracy.

This is typically a national network feed. Some of the ads are high-priority national ads and some of the ads are low-priority national ads that could be replaced by local ads down the chain. These baseband markers are defined in SCTE The baseband markers are translated into compressed stream markers for transmission with the content. The compressed stream markers are defined in SCTE This is where OTT systems take over. The Programmer Side is responsible for generating the compressed bit stream with the appropriate ad insertion markers.

A general diagram is presented in Figure 1. The interface between the automation system and the inserter is also defined by SCTE It is also possible to skip the inserter and have the automation system directly control the encoder again using the SCTE network interface protocolsbut this is discouraged by the standards.

The final output of the programmer side is a transport stream with the compressed content, plus the SCTE markers. This is the feed to the affiliates and is a good starting point for the OTT ad insertion workflow. Figure 2 shows the traditional ad delivery system. The local affiliate receives the transport stream decorated with SCTE markers from the programmer side. This transport stream goes into a splicer, which reads the markers, contacts an Ad Server using the SCTE protocol to request a replacement ad, and splices the replacement ad in the correct place in the transport stream.

The output of the splicer is a new transport stream with the national low-priority ad replaced by a local ad. Back office management systems will interact with the ad server to facilitate the selection of the ad to be played, and to record the fact that the ad has been played for tracking purposes.

The resulting output is a fully compliant linear stream, decodable by any set-top box, no special features or functionality needed. This stream typically goes into a cable plant, or a terrestrial transmitter, and all receivers in the service area show exactly the same ad. A variation of the traditional system has been proposed in the SCTE standard to allow for a small amount of individual ad targeting.

Markers are left in place and processed by the receiving set-top boxes. The set-top box will then decide which one of the small number of available ads to display or not; it can also leave the ad in the main program. This allows for a very limited amount of ad targeting.

Figure 3 shows the basic OTT operation. Each segment is individually decodable—in other words, no data from a previous segment is required to start decoding it and it can be decoded up to its last frame, with no data required from the next segment.

For H. The manifest lists the segments and there is a top-level manifest that lists the available profiles and their characteristics. Manifests are text files, and their format changes from standard to standard.This includes providing the appropriate metadata in streams to denote when advertisements should begin and end, as well as information describing which advertisements should be inserted.

This largely delves into the realm of the SCTE specification. You can freely download the full specification from the SCTE website. The particular use cases we care about involve taking raw HD-SDI feeds from broadcasters in the studio and transporting them across the network.

In order to reliably transmit advertising metadata, we need to take the raw SCTE data, convert it to SCTE when we encode the video into a transport stream, and then do the reverse process at the receiving end.

We were hoping to find some good open source libraries or functionality in existing encoding toolkits such as ffmpeg or gStreamer. However surprisingly few such libraries exist. The library does not currently support Component Mode or encrypted payloads although we may add these in the future if need arises. This tool has been instrumental for our testing efforts especially given the cost and limited feature set of commercial H.

This sounds awesome. Do yo plan to support FFmpeg in the future? This could change if there is a commercial entity interested in financing the work, but there is nothing on the roadmap currently.

There are many opportunities in the video transport sector - more than ever, in fact. New programming channels pop up seemingly every day, and the growth of over-the-top OTT and online content delivery means that many incumbent broadcasters and new entities are expanding their delivery streams and diversifying their services. These viewing options offer expanded development possibilities for many traditional TV services, such as target advertising that uses geo-location and customer input to tailor promotional material and viewing capacities that use user settings to offer them content the way they want it.

What is SCTE 35? DPI is what allows broadcast affiliates to program local commercials or short programs into national broadcasts. It identifies cue messages that are then embedded into the outgoing stream, which provide timing information and indicate splice points, according to Broadcast Engineering. What is SCTE ? SCTE acts as a translator for communications between the automation and compression points of the system that inserts SCTE 35 private sections into an outgoing video transport, according to Broadcast Engineering.

The system will log all SCTE35 messages discovered in the transport streams and perform triggered recording for the verification of Ad insertion process. Video advertising is a major revenue source for many broadcasters and video service providers. Video advertisements for linear broadcast are inserted into regular program transport streams using digital program insertion technique.

Both video service providers and advertising agencies want to know that advertisements are properly broadcasted, and ideally that the advertisements are watched by TV viewers. The SCTE35 defines splicing messages that inform the down-stream processing equipment to insert the advertisement at proper splicing points.

Once the down-stream Ad inserter receives the splicing message, the inserter can request the Ad program from Ad server and insert the program into a regular program. The triggered recording functionality can automatically record a piece of transport stream upon the appearance of a splicing message.

Tools for searching and playing back video messages are provided. The service providers can use the system to monitor if the SCTE35 messages are present in the streams, and verify that Ad programs are inserted at the splicing points. All SCTE35 tables are decoded and its content and arrival timestamp are recoded in the system database.

The system provides tree view display of decoded SCTE35 table content, bar chart graphic display of SCTE35 splicing message arrival time, and easy to use UI for querying recorded messages based on time period, input, transport stream ID, etc. The system can automatically record transport streams triggered by the appearance of SCTE35 tables. The recording parameters can be configured, including the file size of each recording, time interval, maximum number of recordings for the same trigger code.

Recorded files are saved in local hard drives, while file metadata are saved in the system database for easy search and management of the recorded files. Automatic audio fingerprint match can be applied on the recording files to search for specific content. The software provides a simple UI for searching and playing back recorded contents. Multiple recording files can be selected and played in sequence.

Well, yes we can! Adding Crystal insertion software to an existing chain makes the system smarter, more flexible and able to provide richer messages which drive downstream services.

The same goes for SCTE 35, where expecting hardware-based transcoders to keep up with standards and your business goals are unrealistic. The latter can be highly effective when producing multiple streams that need different SCTE message profiles. Crystal also makes manual interfaces, like touch screens, which allow operators to manually trigger SCTE message insertion and provides them with confirmation SCTE messages were inserted.

If you feel stuck with your current hardware-based solution, or are implementing a new system and want to understand the benefits of software-driven SCTE workflows then please contact Crystal for more information on how our solutions can help you.
