1 Introduction This document describes the in-band distribution format for Event Triggering according to SCTE standards. The purpose of Event Triggering is to allow applications and services downstream to perform and support a variety of features. Examples of these features are, but are not limited to: National and targeted ad-insertion Anti-ad skipping Content blanking Archiving Video-on-Demand triggering Electronic Program Guide update provision Regional windowing Audio loudness measurements Channel and Program identification Logo insertion More functionality can be added in the future, while using the same or added in-band information. The signalling can be applied in linear broadcasting as well as in streaming applications. The triggering is extended with out-of-band metadata to provide more detailed information about a certain trigger, the identity and the corresponding action. 2 References The in-band signalling complies with the following standards and recommendations: ANSI/SCTE-35 2017 ANSI/SCTE-104 2017 ANSI/SCTE-67 2014 SMPTE ST2010 2008 IETF RFC 4122 1998 ETSI TS 101 231 v1.3.1 EBU TS 101 231 Codes Register 2015-12 Digital Program Insertion Cueing Message for Cable.

3 Generation and distribution Figure 3.1 shows generic examples of the signal flow between a broadcasting station and several methods of distribution. Signalling according to SCTE-104 is generated by the play-out automation at the broadcasting station and is locally distributed via LAN. Alternatively, SCTE 104 signalling can also be generated by an intermediate system that communicates with the play-out automation and the scheduling system. An embedder adds the signal according to SMPTE ST2010 to the (HD)SDI output of the play-out system. Three different imaginary distribution forms are displayed. From top to bottom: Traditional linear transmission encoded by the distributor combined with web based delivery (OTT). Linear transmission from the broadcast station combined with OTT provided by the distributor. OTT combined with third party access. Distributors that process the (HD)SDI signal receive the signalling embedded. DVB encoders convert the event messages to SCTE-35 data, distributed in a dedicated DVB Packet Identifier (PID) individually per service and timealigned combined with video, audio and other data of the television service. The SCTE-35 PID data can be decoded downstream for features as described in section 1.

4 Encryption To avoid abuse, it is of utmost importance that the triggering data is blocked at the distributor's head-end or encrypted downstream, as it would otherwise be accessible at the viewer's end. There shall be no option to disclose the data by the subscriber or by any other non-authorised third party, for example by using a personal computer and/or additional hardware. The specific use of encryption therefore is a main topic of mutual arrangement, clarity and understanding. 5 Event Triggering In this specification, all individual broadcast events in the linear playlist are signalled. The event elements can be distinguished as follows: Segment Program Chapter Interstitial Advertisement Break Provider Placement Distributor Placement A uniquely identifiable broadcast playlist element such as a Program, a Chapter of a Program or an Interstitial. An individual, self-contained audio-visual item, not being an Interstitial. A part of a Program followed by one or more Interstitials or by the Chapter of another Program. Chapters are sequentially numbered per Program. An individual, self-contained Advertisement, billboard, promotional (promo) or similar item, not being a Program. Interstitials are sequentially numbered per Break. An individual, self-contained commercially oriented Interstitial, not being a billboard, a promo or a similar item. A complete block of one or more Interstitials in advance of, interrupting or following up a Program. Breaks are sequentially numbered per Program. A block of one or more Advertisements. There can be more than one Provider Placement 1 present within one Break. A block of one or more Advertisements identified to be available for local replacement by one or more Distributor Advertisements. This arrangement is also known as Avail'. There can be more than one Distributor Placement 1 present within one Break. Signalling is performed using the segmentation_type_id values as defined in Table 8-8 of SCTE-35. The following values are expected to appear in pairs: Program / Chapter / Provider Advertisement / Distributor Advertisement / Break / Provider Placement Opportunity / Distributor Placement Opportunity / Unscheduled Event / Network / A Program can be replaced by a Program Early Termination if necessary. A Program interruption can also include a Breakaway (a Program in a Program), a Resumption (a continuation of the previous Program after a Breakaway), a Planned Run-over (an extension of the original duration) and an Unplanned Run-over. These exceptions only apply if inserted between Program and Program /Early Termination. The referenced version of the SCTE-35 standard does not include a dedicated segmentation_type_id for promotional items or 1 A collection of Provider and Distributor Placements is sequentially numbered per Break. 6/46
billboards. These segments are therefore signalled with the Advertisement / identification. 6 Format and timing The standard offers the opportunity to keep using traditional splice_insert() commands in order to stay downwards compatible with older equipment. In this specification it is assumed that downstream equipment is up to date. To avoid interference, all events are signalled using messages only. Messages other than immediate triggers shall contain a valid timestamp which points to the frame accurate start and stop time of the event. To avoid undefined behaviour, a pre-roll time of 4 seconds is included in the message. There are nevertheless always situations where the start or end of a broadcast item must be signalled immediately instead of planned. This can be done by setting the time_specified_flag to 0, which means that there is no time reference included in the message. A typical application is the end of a live event which is determined real-time. The consequence of using an immediate command is that processes which make use of the triggering cannot be controlled with the usual timing accuracy. Devices and applications that process the commands shall be aware that this may happen and shall handle them in the best possible manner. To achieve correct timing, the Automation System which generates the SCTE-104 messages, must be able to configure a static time offset to compensate for any video delay, if relevant, between the playout system and the encoder. If the Automation System feeds the same messages to more than one video encoder for example, the same TV channel in HD and SD resolution this time offset shall be independently configurable. The timing reference is UTC. Theoretically, an issued command can be updated by sending a new message with the correct or more accurate data or it can be cancelled by a message which has the segmentation_event_cancel_indicator_flag set to 1. This is however not included in this specification. Figures 6.1-6.4 describe some sample events in further detail using the syntax according to SCTE- 104. The samples do not indicate a limitation; several combinations can be active at the same time if, for example, a Program is interrupted by other Programs (Program Breakaway). The yellow blocks include the segmentation_descriptor() values for the corresponding events. The messages also include Content Identification data. This is further described in section 7. 7/46

7 Identification The SCTE-35 standard allows using segmentation_type_id and segmentation_upid descriptors to send identification of the transmitted content. According to this specification, the information is sent as: A general part A which contains the start and stop triggers, the Airing ID and generic transmission flags. A specific part B transmitted as Managed Private Data. This data includes the format identifier ('RTLN' in this document) as disclosed by the SMPTE Registration Authority. Managed Private Data contains additional identification. It is also sent in messages that signal individual Interstitials in order to refer to the Program they run with. General part: A.

Network / The RTL Network / ID Specific part: B. Using segmentation_type_id 0x01 Content Identification and segmentation_upid_type 0x0C Managed Private UPID Format identifier Country and Network Identification (CNI) Version number Uses a 32 bit value format_identifier representing the ASCII name 'RTLN' as disclosed by the SMPTE Registration Authority. Uses a 16 bits hexadecimal value private_cni which refers to the ETSI TS 101 231 Codes Register. The CNI identifies the Service Name or Channel Name. Uses an 8 bits unsigned numeric value private_version which indicates the lay-out version of the data. It is changed if a new one is not downwards compatible with earlier versions. Extension of the data fields while the original content is preserved does not lead to a new version number. Applications downstream shall be prepared that the number of data fields in the descriptor loop may be extended. Material ID Uses an 11 character long alphanumeric string 5 Library key 7.1 Heartbeat private_material_id which refers to the RTL File/Tape ID of the running Program. Uses a 9 character long alphanumeric string private_library_key which points to the RTL Rights ID of the running Program. The Heartbeat is a repetitive message type B as described in the previous section which can be used to monitor the proper operation of the system. It includes Content Identification data which allows periodic signalling of the running content and allows quick recovery of the service after a failure. Section 8.9 shows an example of the syntax. A proper frequency of the Heartbeat signal alongside other messages is every 30 seconds, which can be changed according to necessity and available capacity. and messages always have priority above Heartbeats. 5 All string lengths are fixed. The specification includes a null terminator character (0x00). The content of a string can fill fewer characters than the maximum length, as long as it is followed by that null character (\0). Any remaining characters shall be ignored. Text is based on 8 bit ASCII characters. 13/46
