Description
METHOD AND TRANSMITTING DEVICE FOR
TRANSMITTING ZAPPING DATA
The invention relates to a method and a transmission device for the transmission of zapping data, that is to say, channel-switching data for switching the channels, for example, of a television receiver.
Within the European Digital-Video-Broadcast-Handheld transmission standard (DVB-H) and also in the corresponding American transmission standard A-VSB of the American digital-television standards ATSC, the transmission data associated in the mobile receiver device with a channel or service are transmitted in each case only in periodically-arranged burst intervals as shown in Figure 1. The component groups of the mobile communications device associated with reception are switched off, between the burst intervals AtA
and respectively AtB associated with the received channel or service in each case during the time intervals ATA and ATB, thereby minimising the energy consumption of the mobile communications device.
At time tl, as shown in Figure 1, if the user of the mobile communications device switches channel or changes service or implements an initial channel or service selection, the reception of the channel or service during the change or during the initial selection, is delayed by the delay time
TRANSMITTING ZAPPING DATA
The invention relates to a method and a transmission device for the transmission of zapping data, that is to say, channel-switching data for switching the channels, for example, of a television receiver.
Within the European Digital-Video-Broadcast-Handheld transmission standard (DVB-H) and also in the corresponding American transmission standard A-VSB of the American digital-television standards ATSC, the transmission data associated in the mobile receiver device with a channel or service are transmitted in each case only in periodically-arranged burst intervals as shown in Figure 1. The component groups of the mobile communications device associated with reception are switched off, between the burst intervals AtA
and respectively AtB associated with the received channel or service in each case during the time intervals ATA and ATB, thereby minimising the energy consumption of the mobile communications device.
At time tl, as shown in Figure 1, if the user of the mobile communications device switches channel or changes service or implements an initial channel or service selection, the reception of the channel or service during the change or during the initial selection, is delayed by the delay time
2 AtvA and respectively AtvB as a result of the periodicity of the burst interval associated with the respective channel or service. During the delay times AtvA and respectively Atvs, no reception of the respectively-selected channel A or B is possible. The delay times AtvA and respectively AtvB must be bridged.
Especially in the case of a switch of channel or a change of service, the user of the mobile communications device is offered so-called zapping data (channel-switch data) in order to bridge the delay. These zapping data can provide either specific service information or channel data with reduced channel contents. Zapping data are preferably used in audio channels for the transmission of audio content with a reduced bandwidth. In WO 2006/031925 A2, zapping data of this kind are transmitted in advance, buffered in the mobile communications device and displayed to the user of the mobile communications device as required in the event of a channel or service switch, i.e. during zapping. The provision of a buffer memory for zapping data in the mobile communications device represents a disadvantage in a method of this kind for the transmission of zapping data.
The object of the invention is therefore to provide a method and a transmission device for the transmission of zapping data without buffering the zapping data in the mobile communications device.
This object is achieved with reference to the method by the features of claim 1 and with reference to the transmission

The object of the invention is therefore to provide a method and a transmission device for the transmission of zapping data without buffering the zapping data in the mobile communications device.
This object is achieved with reference to the method by the features of claim 1 and with reference to the transmission
3 device by the features of claim 8. The dependent claims specify advantageous further developments.
According to the invention, the zapping data are transmitted at a second data rate different from the first data rate with the channel or service data transmitted in individual burst intervals. Since the zapping data represent channel or service data with reduced channel or service content, the second data rate provides a lower bandwidth than the first data rate.
In a first embodiment of the method according to the invention, the zapping data are transmitted continuously in a first time interval between two successive burst intervals. In this context, the first time interval can begin with a delay by a second time interval by comparison with the end of the preceding burst interval, and can end prematurely by a third time interval by comparison with the beginning of the subsequent burst interval.
In a second embodiment of the method according to the invention, the zapping data are transmitted discontinuously in several fourth time intervals spaced in time between two successive burst intervals.
In a third embodiment of the method according to the invention, the zapping data are transmitted continuously over the entire time, that is to say, also during the individual burst intervals.
The three embodiments of the method according to the invention for the transmission of zapping data are explained

The three embodiments of the method according to the invention for the transmission of zapping data are explained
4 in detail below with reference to the drawings. The drawings are as follows:
Figure 1 shows a conventional datarate-time diagram with channel data in a DVB-H transmission system;
Figure 2 shows a datarate-time diagram with channel and zapping data in a first embodiment of the method according to the invention for the transmission of zapping data; and Figure 3 shows a datarate-time diagram with channel and zapping data in a second embodiment of the method according to the invention for the transmission of zapping data;
Figure 4 shows a datarate-time diagram with channel and zapping data in a third embodiment of the method according to the invention for the transmission of zapping data.
In the event of an initial channel selection or a channel switch with the first embodiment of the method according to the invention for the transmission of zapping data, at time ti according to Figure 2, with an initial selection of channel A or a switch to channel A, channel A with zapping data A, which represent channel data of channel A with a reduced channel content transmitted at a second data rate within a first time interval (AtiA) between two burst intervals AtA are displayed to the user of the mobile communications device. Accordingly, there is no delay time AtVA =

Figure 2 shows a datarate-time diagram with channel and zapping data in a first embodiment of the method according to the invention for the transmission of zapping data; and Figure 3 shows a datarate-time diagram with channel and zapping data in a second embodiment of the method according to the invention for the transmission of zapping data;
Figure 4 shows a datarate-time diagram with channel and zapping data in a third embodiment of the method according to the invention for the transmission of zapping data.
In the event of an initial channel selection or a channel switch with the first embodiment of the method according to the invention for the transmission of zapping data, at time ti according to Figure 2, with an initial selection of channel A or a switch to channel A, channel A with zapping data A, which represent channel data of channel A with a reduced channel content transmitted at a second data rate within a first time interval (AtiA) between two burst intervals AtA are displayed to the user of the mobile communications device. Accordingly, there is no delay time AtVA =
In the case of an initial selection of channel B or a switch
5 to channel B, the user of the mobile communications device is shown channel B with zapping data B, which represent channel data of channel B with a reduced channel content.
The delay time At is reduced by comparison with a channel transmission in a DVB-H or ATSC transmission system according to the prior art, as shown in Figure 1, because zapping data B are transmitted at the second data rate within the first time interval At1B between two burst intervals At13.
As shown in Figure 2, the first time intervals AtIA and respectively Atn, in which respectively zapping data A and B are transmitted, can be delayed by comparison with the end of the respectively-preceding burst interval for the transmission of channel data A and B by a second time interval At2A and respectively At23, and can end prematurely by comparison with the beginning of the respectively-subsequent burst interval by a third time interval At3A and respectively At33.
In the second embodiment of the method according to the invention for the transmission of zapping data, the zapping data for channel A or B are transmitted between successive burst intervals of the channels A or B in several fourth time intervals At4A and respectively At43 each spaced in time. As illustrated in Figure 3, the individual fourth time
The delay time At is reduced by comparison with a channel transmission in a DVB-H or ATSC transmission system according to the prior art, as shown in Figure 1, because zapping data B are transmitted at the second data rate within the first time interval At1B between two burst intervals At13.
As shown in Figure 2, the first time intervals AtIA and respectively Atn, in which respectively zapping data A and B are transmitted, can be delayed by comparison with the end of the respectively-preceding burst interval for the transmission of channel data A and B by a second time interval At2A and respectively At23, and can end prematurely by comparison with the beginning of the respectively-subsequent burst interval by a third time interval At3A and respectively At33.
In the second embodiment of the method according to the invention for the transmission of zapping data, the zapping data for channel A or B are transmitted between successive burst intervals of the channels A or B in several fourth time intervals At4A and respectively At43 each spaced in time. As illustrated in Figure 3, the individual fourth time
6 intervals At4A and respectively At4B can be spaced periodically or can also be spaced at irregular time intervals. Moreover, the length of the individual, successive fourth time intervals At4A and respectively At43 need not necessarily be constant.
Dependent upon the position of the timing point t1 of the initial selection of the respective channel A or B, or of the switch to channel A or B relative to the respective fourth time interval At4A or respectively At43, delay times AtvA and respectively AtvB are obtained, which are reduced by comparison with the previously-conventional transmission within a DVB-H or ATSC transmission system as illustrated in Figure 1. By comparison with the first embodiment of the method according to the invention, relatively-longer delay times AtvA and respectively AtvB can occur under some circumstances within two successive burst intervals in the second embodiment of the method according to the invention because of the discontinuous distribution of the individual fourth time intervals At4A and respectively At.
In the third embodiment of the method according to the invention for the transmission of zapping data, the zapping data for channel A or B are transmitted continuously over the whole time as shown in Figure 4. Accordingly, the user can also only access the zapping data associated with channel A or B during the burst intervals AtA, or AtB
without selecting the channel or service data associated with channel A or B.
