Functions | |
| void | MHEG5setInputEventRegister (MHEG5Int inputEventRegister) |
| Change the input event register. This indicates which keypresses the MHEG-5 engine requires to be passed. See UK 1.05 profile section 3.6 for a description of which keypresses must be passed to MHEG-5 for the different input event register values. These values are likely to change for UK1.06 profile. More... | |
| 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[.*]. More... | |
| 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. More... | |
| 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. More... | |
| MHEG5Int | MHEG5GetDisplayAspectRatio (void) |
| Find the setting of the attached display's aspect ratio This function is used by the GetDisplayAspectRatio resident program. See UK1.06 profile section 3.10.8.3. More... | |
| MHEG5Bool | MHEG5GetBasicSI (MHEG5Int serviceIndex, MHEG5Int *networkID, MHEG5Int *origNetworkID, MHEG5Int *transportStreamID, MHEG5Int *serviceID) |
| Returns a series of integers representing basic Service Information (SI) about a service. The service is identified by means of a receiver specific "ServiceIndex". This integer can be determined by means of the SI_GetServiceIndex resident program (see 3.10.6.1, "SI_GetServiceIndex", on page 3-20). This function is used by the SI_TuneIndexInfo resident program. See UK1.06 profile section 3.10.6.3. More... | |
| void | MHEG5restoreReceiverDefaults (void) |
| Restore receiver defaults as described in section 3.12.10 of the 1.06 profile. More... | |

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.
| 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.
| serviceReference | ServiceReference defines a Stream using the URL format defined in DAVIC 1.3 part 9 paragraph 9.5. See also 8, "Name Mapping", on page 8-1 |
| MHEG5Bool MHEG5parseUrl | ( | U8BIT * | buffer, |
| U32BIT | length, | ||
| S_DVB_LOCATOR * | multiplexRef | ||
