hi @token-stranger, can you tell me how to get this link?
http://wowza-rr-live-1.edgeware.tvb.com/mytvlive/smil:mobilehd_jade.smil/playlist.m3u8?sig=682072e3f61755d36e4f58745749d03f&ext_start_limit=1462866741&int_start_limit=1462866741&ts=1462945941
Thank you very much!

actually is it mean that all these links will expire? and there is no permanent link?

Let's clarify.

1. I am not in Hong Kong.
2. The links appears to be geo-locked, so a Hong Kong proxy/ VPN (preferable) or a SmartDNS is needed for those outside of Hong Kong.
3. I used the links listed above but added "?app=mytv" (without the quotation marks) to each link. Example,
   http://token.tvb.com/stream/live/hls/mobilehd_jade.smil?app=mytv
4. This link will automatically re-direct to the wowsa server (happens almost immediately and may not be noticeable), and re-directs to an IP number, usually 202.126.xxx.xxx.
5. I ran the links through an iPad, iPhone and an Android phone.
6. It works better on iOS devices because .m3u8 formats are more native on Apple devices than Android's, especially when played through the Safari browser.
7. Surprising, Jade and iNews streams are quick and extremely reliable. J2 and J5 are hits and misses, working periodically. Uncertain why.
8. All re-directed links are not permanent, requiring new tokens each time.

I hope that answers most queries.

@ token-strange. Thanks for your clarification. But i have one question. I have tried to use http://token.tvb.com/stream/live/hls/mobilehd_jade.smil?app=mytv and try to get the ip as you mention but i am unable to do so. I only able to get below link. Can you advise me how you get it?

http://vdo-live-cache-akamai.cdn.tvb.com/mytvlive/smil:mobilehd_hdj.smil/chunklist_b1536000.m3u8

Hi, the link is blocked....

@shawn35

I can only speak from experience. When I am not in Hong Kong, and I connect to

http://token.tvb.com/stream/live/hls/mobilehd_jade.smil?app=mytv

without a proxy/VPN or a smart DNS service, that link above will resolve to a similar link like what you have highlighted.

http://vdo-live-cache-akamai.cdn.tvb.com/mytvlive/smil:mobilehd_hdj.smil/chunklist_b1536000.m3u8?xxxxxxxxx

I cannot tell beyond what I don't know about. It's probably geo-location locked.

@token-stranger,

Actually i use hongkong vpn to access the token link.....but it does not goes to the ip link that you mention. which is why i am wondering how you get the ip address link

http://token.tvb.com/stream/live/hls/mobilehd_jade.smil?app=mytv
HTTP ERROR 403 now :(

Are the links deleted? There's no vital sign!

TVB fix GOTV and MYTVSUPER.

GOTV and MYTVSUPER fix

So I had some time to investigate this again. Funnily enough, if you can trick the myTV app into thinking it's inside HK (by returning a modified JSON response for example), you can still use the app like normal for live tv.
Accessing the URL stream itself isn't as simple as just loading it up now though, the way the app works is that it'll load up the URL like so:

http://token.tvb.com/stream/live/hls/mobilehd_jade.smil?time=*current epoch time in milliseconds*&app=mytv4

The time parameter is required, the app parameter however can be omitted but what the app will also send is a certain request header like so:
Key: t
Value: eeeeb6ee6a25e9ef0fa17e27fe39f7ee0a917d0d761688c83d840b52cfc7fc8e

Supply a valid t request header and the stream link is usable outside the app. Unfortunately I'm not sure how the value's generated so once I get more time, I can research further into that matter.

EDIT: Further examination with the app seems to suggest that the time in milliseconds is encrypted to provide the value for 't'. The encryption method is hidden behind a shared object library so I can't find out how it's getting encrypted without performing disassembly on the file. Judging from the values I've seen over repeated requests, it may seem like two MD5 hashes contatenated with each other.
