MediaTailor variáveis de sessão para solicitações do ADS

Caso o ADS exija um parâmetro de consulta chamado deviceSession a ser passado com o identificador da sessão exclusivo, o URL ADS do modelo em AWS Elemental MediaTailor pode se parecer com o seguinte:

https://my.ads.server.com/path?deviceSession=[session.id]

AWS Elemental MediaTailor gera automaticamente um identificador exclusivo para cada fluxo e insere o identificador no lugar desession.id. Se o identificador for1234567, a solicitação final MediaTailor feita ao ADS seria mais ou menos assim:

https://my.ads.server.com/path?deviceSession=1234567

Se o ADS exigir que vários parâmetros de consulta sejam passados, o modelo de URL do ADS AWS Elemental MediaTailor pode ter a seguinte aparência:

https://my.ads.server.com/sample?e=[scte.avails_expected]&f=[scte.segment_num]&g=[scte.segments_expected]&h=[scte.sub_segment_num]&j=[scte.sub_segments_expected]&k=[scte.segmentation_type_id]
