René's URL Explorer Experiment

{"@context":"https://schema.org","@type":"DiscussionForumPosting","headline":"Proposal for a  subtitle section ","articleBody":"\r\nWe have been doing EBU-TT-D subtitles tests in HbbTV using streams from HbbTV Reference Application, ARD, DASH-IF, BBC, CCMA, and others. Some of them VOD, but few for Live. Most streams are not intended specifically for subtitles tests, but for other functionalities: Multiperiod, Advertisings, DRM, multi-Moof, etc. \r\n\r\n\r\n![image](https://github.com/HbbTV-Association/ReferenceApplication/assets/20952160/db8c8a0e-c1f7-4557-a06a-c0698a3452c5)\r\n\r\n![image](https://github.com/HbbTV-Association/ReferenceApplication/assets/20952160/e1978eb9-b41e-4d9f-b946-d685eb4dd1bb)\r\n\r\n\r\nSo different streams , different TV sets and too many different behaviours that leads to a bad interoperability because we \r\n\r\nIt would be helpfull to create a section with reference streams for testing only subtitles in HbbTV with HTML5 native player.\r\nIn order to work in the largest number of devices, the streams should be compliant to these profiles, though we understand that there are some devices where subtitles will not work :\r\n* \"urn :dvb :dash :profile:dvb-dash:2014 \" (HbbTV 2.0 DASH profiles)\r\n* \"urn: hbbtv :dash :profile:isoff-live:2012\" (HbbTV 1.5 DASH profiles)\r\n* \"urn: hbbtv :dash :profile:isoff-live:2011\" \r\n\r\nIn this subtitles section it would be interesting to have at least  the four streams as described below which are focused only on subtitles avoiding other features  that could mask the results. \r\n\r\n* VOD Stream PROFILE \"MP4_AVC_HD_25_HEAAC_EBUTTD\"\r\n  * 1 Stream with 1 subtítle \"in band\"\r\n  * 1 Stream with 2 languages subtitles \"in band\"\r\n* LIVE Stream PROFILE \"MP4_AVC_HD_25_HEAAC_EBUTTD\"\r\n  * 1 Stream with 1 subtítle \"in band\"\r\n  * 1 Stream with 2 languages subtitles \"in band\"\r\n\r\nHow these reference streams and reference player could help:\r\n* A group of official reference streams is needed for testing subtitles on VOD and Live. These reference streams, only intended for testing subtitles.\r\n* This would facilitate communication between the different actors, content providers, developers, device manufacturers and streaming services providers, helping to detect and solve interoperability problems.\r\n\r\n\r\n","author":{"url":"https://github.com/CCMA-Enginyeria","@type":"Person","name":"CCMA-Enginyeria"},"datePublished":"2023-11-03T12:03:34.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":4},"url":"https://github.com/78/ReferenceApplication/issues/78"}
