sl@0: 
sl@0: 
sl@0: 5
sl@0: 00:00:18,000  -->  00:00:21,000
sl@0: It is officially in Symbian OS 
sl@0: Diran only, but the code is 
sl@0: 
sl@0: 6
sl@0: 00:00:21,000  -->  00:00:24,000
sl@0: present in 9.5 releases and is 
sl@0: easy to enable and build. 
sl@0: 
sl@0: 7
sl@0: 00:00:26,000  -->  00:00:29,000
sl@0: This demo runs under a stock 
sl@0: Symbian OS 9.5 DevKit release. 
sl@0: 
sl@0: 8
sl@0: 00:00:29,000  -->  00:00:32,000
sl@0: We have simply enabled NGA, 
sl@0: enabled PREQ1939, 
sl@0: 
sl@0: 9
sl@0: 00:00:32,000  -->  00:00:35,000
sl@0: rebuilt MMF, and added a
sl@0: simple demo application. 
sl@0: 
sl@0: 10
sl@0: 00:00:35,000  -->  00:00:38,000
sl@0: Detailed build info 
sl@0: and this demo application is 
sl@0: 
sl@0: 11
sl@0: 00:00:38,000  -->  00:00:41,000
sl@0: available on request. 
sl@0: 
sl@0: 12
sl@0: 00:00:44,000  -->  00:00:47,000
sl@0: PREQ1939 requires that video 
sl@0: playback uses graphics surfaces. 
sl@0: 
sl@0: 13
sl@0: 00:00:47,000  -->  00:00:50,000
sl@0: The actual subtitles however 
sl@0: are rendered as UI graphics
sl@0: 
sl@0: 14
sl@0: 00:00:50,000  -->  00:00:53,000
sl@0: Using a Content Rendering 
sl@0: Plugin (CRP) in Window Server. 
sl@0: 
sl@0: 15
sl@0: 00:00:55,000  -->  00:00:58,000
sl@0: The PREQ delivery includes all 
sl@0: MMF and API changes, 
sl@0: 
sl@0: 16
sl@0: 00:00:58,000  -->  00:01:01,000
sl@0: a product-quality CRP for 
sl@0: subtitle rendering, 
sl@0: 
sl@0: 17
sl@0: 00:01:01,000  -->  00:01:04,000
sl@0: and a reference SRT subtitle 
sl@0: renderer in the AVI controller. 
sl@0: 
sl@0: 18
sl@0: 00:01:06,000  -->  00:01:11,000
sl@0: This demo uses a video-only 
sl@0: AVI file with MPEG-4 video 
sl@0: 
sl@0: 19
sl@0: 00:01:11,000  -->  00:01:14,000
sl@0: and a hand-written SRT 
sl@0: subtitle file. 
sl@0: 
sl@0: 20
sl@0: 00:01:16,000  -->  00:01:19,000
sl@0: Real-world implementations 
sl@0: are expected to use 
sl@0: 
sl@0: 21
sl@0: 00:01:19,000  -->  00:01:22,000
sl@0: 3GPP Timed Text instead. 
sl@0: 
sl@0: 22
sl@0: 00:01:22,000  -->  00:01:25,000
sl@0: In any case, all subtitles are 
sl@0: rendered in the controller and 
sl@0: 
sl@0: 23
sl@0: 00:01:25,000  -->  00:01:28,000
sl@0: displayed directly using a CRP. 
sl@0: 
sl@0: 
sl@0: 24
sl@0: 00:01:28,000  -->  00:01:31,000
sl@0: The application is not on the 
sl@0: data path at all, and has only 
sl@0: 
sl@0: 25
sl@0: 00:01:31,000  -->  00:01:34,000
sl@0: basic control functionality. 
sl@0: 
sl@0: 
sl@0: 26
sl@0: 00:01:36,000  -->  00:01:59,000
sl@0: Thank you
