Communications
6.1. Tier 0 Requirements
Tier 0 insertion is non-Program-Specific Ad Insertion using SCTE 35[1] Cue Messages. To support Tier 0 insertion, the following data elements shall be provided in the schedule data.
6.2. Tier 1 Requirements
Tier 1 insertion is Program-Specific Ad Insertion using SCTE 35 [1] Cue Messages, but does not require matching the avail_num or avails_expected fields of SCTE 35. To support Tier 1 insertion, in addition tothe Tier 0 fields above, the following additional data element shall be provided in the schedule data.
6.3. Tier 2 Requirements
Tier 2 insertion is Program-Specific Ad Insertion using SCTE 35 [1] Cue Messages requiring matching the avail_num and avails_expected fields in SCTE 35 messages. To support Tier 2 insertion, in addition to the Tier 0 & Tier 1 fields above, the following data elements shall be provided in the schedule data.
A Network shall communicate all data elements required for Tier 2 support in the Cue Messages that will exist in the data stream for the Program. Due to the Tiered Insertion behavior logic (see SCTE 118- 1[12], section 6.3), if an Ad Insertion System recognizes a Cue Message containing Tier 1 or Tier 2 data elements, it will attempt to insert any open window, non-Program-Specific ad content. A Network may prevent insertions associated with Cue Messages not intended for a particular Affiliate through the use of the AuthorizedName (see Section 6.4). If a Network is using Tier 1 behavior, there is no way to prevent or direct an Affiliate to ignore a particular Cue Message.
6.4. Optional Data Items The following are additional items that may appear for each Program. Optional items may be used in implementations of any Tier.ANSI SCTE 118-2 pdf download.
