One thing that’s missing is the low-latency old analog systems had changing channels. Has anyone figured out a way to achieve this in the digital era?
- joezydeco 1y agoI worked on a DVB-H receiver back in the day and we tried to speed it up by having a complete second tuner in hardware and starting the acquisition on the next stream while decoding the first one.
- thakoppno 1y agoThat’s fun. I suppose flipping up channels is far more common than down, but presumably one direction would be faster with this solution.
- justinsaccount 1y agoNot really. the definition of what the 'next' stream is could easily change depending on what the last button you pressed, with the assumption that you would continue pressing that button: * up - next stream is one more channel up * down - next stream is one more channel down * last/prev - next stream is the previous channel.
- joezydeco 1y agoWe reversed the direction if the user started going backwards. We talked about a third tuner to hold the previous channel if they decided to reverse direction but the cost wasn't worth it. The whole technology was kind of a dead man walking by that point in history. iPhone killed it all.
