Functions | |
| MHEG5Bool | MHEG5parseUrl (U8BIT *buffer, U32BIT length, S_DVB_LOCATOR *multiplexRef) |
| Parse a DAVIC style multiplex reference or UK-DTT inherritance format URL. This can be one of the following forms: rec://svc/cur rec://svc/def rec://svc/lcn/# dvb://original_network_id.[transport_stream_id].service_id[.*]. | |
| MHEG5Int | MHEG5GetServiceIndex (MHEG5String *serviceReference) |
| Ref:[1] - 3.10.6.1 and [1] - 3.10.6.3 Get the serviceIndex, a positive integer which is used to reference a service, based on the DVB URL (MHEG5_dvbLocator). NONE. | |
| void | MHEG5SetSubtitleMode (MHEG5Bool subtitleOn) |
| Set the current subtitle display mode to be either On or Off, Should only have an impact if subtitles can be displayed simultaneously with MHEG. This function is used by the SetSubtitleMode resident program. See UK1.06 profile section 3.10.8.4. | |
| MHEG5String | MHEG5GetBootInfo (MHEG5Bool *InfoResultVal) |
| Tell whether a network_boot_info sub-descriptor has been found and received. If so, returns the value of the NB_info field of the network_boot_info sub-descriptor. This function is used by the GetBootInfo resident program. See UK1.06 profile section 3.10.7.3. | |
| MHEG5Int | MHEG5GetDisplayAspectRatio (void) |
| Reads the format of the connected display (4:3 or 16:9) This function is used by the GetDisplayAspectRatio resident program. See UK1.06 profile section 3.10.8.3. | |

| void | MHEG5SuppressMHEGGraphics (MHEG5Bool request) |
| Request that the external application toggles between showing MHEG graphics or subtitles This function is used by the SuppressMHEGGraphics resident program. See CI+ specification section 12.8.1.2. | |
| void | MHEG5restoreReceiverDefaults (void) |
| Restore receiver defaults as described in section 3.12.10 of the 1.06 profile. | |
| MHEG5Bool | MHEG5getICSupport (MHEG5Int val) |
| Determines whether the system supports Interaction channel. | |
