One of the biggest issues for switchable signing is that it would require significant hardware support. Getting a manufacturer to support Audio Description for the partially sighted is difficult enough, but signing is an even smaller market to deal with.
I sit on various groups, including a variety of different accessibility forums and I am quite an advocate for accessible technology. However what I must accept is also the commercial view, there is a cost associated with every feature on a product. That cost can be very high and a return on investment is required. To justify the expense of adding a feature it must either contribute to sales or permit the price of a product to be increased without affecting sales. As a feature, video overlay has not been requested beyond the deaf community, so customers who do not request it will not pay for it. The fact that the market is relatively small means that it will not contribute significantly to sales (over 100,000 additional sales per supporting manufacturer would likely be required in this case).
Additionally for the broadcaster, they would need extra bandwidth to broadcast the separate video stream of the signer. This is difficult to justify on Freeview because of the already constrained bandwidth, but is perhaps more practical on Freesat.
To contrast all this doom and gloom, I have to say that new technology is beginning to make accessibility features easier to implement. We now have HD subtitles for HD chanels, AD is now required in most of the new specification documents and perhaps with some of the new hybrid set-top boxes (internet connected devices) on-screen signing need not be so niche. It might be possible for signing to be delivered over an IP connection and over-laid in one of the fancy new boxes that the industry is working on.
One thing I must say however User1111, you stated that there are niche channels for certain ethnic groups available and why not Deaf users. Well, for the most part this is down to the community making this possible. Channels such as BET, B4U, ZeeTV and others are operated as commercial businesses for their markets. When it comes to content the world is more accessible than ever, it would be relatively easy to start a small internet television channel which is totally sign-language based. The news channel Russia Today started that way and is now available via regular broadcasting and I understand the internet sports channel "Cycling TV" is quite profitable.
Technology is the great enabler, as a regular watcher of SeeHear in my youth (despite not having a hearing impairment) I remember when video-phones were first being used by deaf people and now with computers and the internet this technology is much more accessible. Webcams and video calling was not designed for the deaf, but the incremental sales volumes of the entire world market for them has given deaf people access to this advanced technology at a great price. Were I differently enabled in some way then I wouldn't seek for others to support me, I would look to engage in the best way possible towards integration with the mechanisms that society provides.
I think that internet television is the way forward for the deaf and I also feel that through the effect of market forces the technology will be affordable, not specialist and easy to use by all.
