| + | ==Basic Usage== | ||
| + | |||
| + | ===Starting Live TV=== | ||
| + | You can start Live TV different ways. | ||
| + | |||
| + | When you select '''Watch TV''' from the front page, MythTV will automatically go to the last channel that you viewed in Live TV. The first time you ever start Live TV it will go to the default channel you setup in [[Setup Input Connections]]. You can also have it go directly to the program guide. See [[Configuring Frontend#Program_Guide 1.2F2]]. | ||
| + | |||
| + | ===Changing channels=== | ||
| + | |||
| + | While watching Live TV you can change channels various ways. You can type a channel number using the number keys to go directly to that channel. You can press up or down arrows [[Image:RemoteUp.png]] [[Image:RemoteDown.png]], and this will display the name of another channel and the program running there. | ||
| + | |||
| + | Press [[Image:RemoteUp.png]] [[Image:RemoteDown.png]] to browse the program information on the next/previous program with the OSD. Then when you see the program you want, press [[Image:RemoteSelect.png]] and MythTV will jump to that channel. While in Browse mode you can also use [[Image:RemoteLeft.png]] [[Image:RemoteRight.png]] to see what shows are coming up next, by scrolling the program guide earlier and later in time. | ||
| + | |||
| + | There is a pause of several seconds while MythTV buffers the new channel. You can change a frontend setting (Uncheck ''Always use browse mode in Live TV''[[Configuring Frontend#Playback OSD]])to cause up/down arrows to immediately select a new channel but this may be frustrating as it is slow if you are moving through several channels. | ||
| + | |||
| + | ===Controlling Playback=== | ||

| + | |||
| + | ===Pause Live TV=== | ||
| + | |||
| + | Pausing live TV is great when the phone rings during a show or your little ones need a comfort break during a movie. | ||
| + | |||
| + | By pressing [[Image:RemotePause.png]] on your remote the picture will freeze but MythTV will continue to record to the hard drive. The OSD will appear showing seconds behind the real-time broadcast. | ||
| + | |||
| + | Live TV is treated as a recording and it is saved in your media list. The live TV recording will auto expire when the hard drive nears being full. | ||

| + | While the picture stream is paused: | ||

| + | |||
| + | With Chase TV Playback the system can be recording live TV while you are watching the same program behind realtime. It is sometimes referred to as Timeshifting TV. | ||
