thanks in advance
On current blu-ray disks, the subtitles are hard coded on to a particular position in the picture and cannot be moved by the player. This is a big stuff-up by the blu-ray disk association. Many people have highlighted this problem in many threads in this forum as well as in the blui-ray forum. Still no amicable solution is given by the BDA. There are few ways of fixing this problem.
1. A crude, simple but an effective method is to include two subtitle tracks on the disk: one on the black bar and the other fully on the picture. This can be achieved at the authoring stage with negligible effort as it requires only few more clicks. (It is beyond me, why the disk authors and Studios have not thought about this possibility.)
2. Blu ray spec has an optional subtitle repositioning feature. To apply this feature, the subtitles should be included on the disk in text form in contrast to the conventional raster image based subtitles. Then the BD-J software can be used to reposition, resize etc. when the disk is played. Unfortunately, this feature does not work well due to implementation issues of BD-J on different players. (Probably this is due to the ambiguities of BD-J specification.) Sony once tried this method in Immortal Beloved but did not continue with it because this method could create subtitle problems in some players. I think still they are testing this.
3. Raster image based subtitles are used in DVDs and they can be moved by the DVD player by repositioning the subtitle raster image and super imposing it on to the video image. For example, TheaterTek software player can do this for DVDs. In principle, the same method can be applied to blu-ray to reposition raster image based subtitles. However, unfortunately, blu-ray has a protected video path to stop people poking in to the video stream. Therefore, the player manufacturers cannot implement this method (as it essentially interferes with the protected video path) unless the blu-ray disk association carries out necessary testing and develop a certified code (which requires money) to enable repositioning of the subtitle raster image.
4. Blu-ray also has the technical capability to download subtitles if that is provided by the Studio. When I inquired about this possibility from the blu-ray forum, I was told that the region protections and copyright ownerships in different regions could create issues if this method is used. Although it is technically possible, Studios may not use this method as a universal solution for subtitle repositioning.
As a temporary measure some people use image shift function of the projector to shift the image and resize with zooming to expose the lower black bar (yuck!) to read subtitles. This method negates the one of the key functions of CIH: i.e. removing the black bars!
Sony supports CIH by providing anamorphic stretch in their projectors. However, when one of their movies (e.g. Sony Pictures Saawariya) is played on their PS3, the subtitles cannot be read on one of their own projectors if their own anamorphic stretch mode is used. It appears like that they are selling equipment that is not fit for the purpose. I am not a legal expert but there could be legal ramifications as well because it appears like that they have misled the consumer. What a mess.
This problem is not limited to CIH'ers but also applies to blackbar-haters and zoomers as they are forced to watch black bars on subtitled movies.
