Description

System and method for transmitting audio and/or video data
The invention relates to a method and system for transmitting audio and/or video data comprising at least one server accessible through Internet and embodied with a content management module for handling audio and/or video content, and at 5 least one mobile device, in particular a cell phone, having capability to access the Internet and communicate with the at least one server.
Such a method and system are widely known in the art.
The mobile telecommunication network infrastructures 10 that are used in these known methods and systems are continuously improved. Each new network technology offers increased mobile transmission speeds. Illustrative are the maximum transmission speeds that apply for the following network data transmission technologies:
15 - GPRS (General Packet Radio Service) 2.5 G
64 Kb/s
- UMTS (Unif.Mobile Telecomm. System) 3.0 G
2.0Mb/s
- HSDPA (Hi-Sp. Downlink Packet Access) 3.5 G
20 7.2 Mb/s
Unfortunately the above mentioned transmission speeds are often not realised. In practice the mobile network transmission performance is much lower due to, among others, not having a 100% national coverage, long distances from mast transmitter 25 unit to mobile devices and/or the number of simultaneous mobile users. Due to large financial investments and long implementation times the national coverage of the latest technology will at least for some period of time not be 100%. Disadvantageouss is that the transmission performance deteriorates when the dis-30 tance between mast transmitter unit and mobile device increases. Further, if there is more than one user on the transmitter unit, bandwidth is divided between the simultaneous users. As a consequence performance reduction to about 1% of the maximum transmission speed is no exception.
35 A further limiting factor of taking full advantage of the latest technology are subscription costs. High mobile transmission speeds costs more. Most mobile users subscribe to a low or medium transmission speed. The result is that the average mobile data transmission speed for most mobile users is relatively 2 low.
As an example a video message of 30 seconds using MPEG 4 compression has a data storage volume of about +/- 500 KB. To transmit this data via UMTS under ideal circumstances would take 5 about 2 seconds. When the mobile network performance is less ideal it could take several minutes to download. This low transmission performance makes distribution of video messages unacceptable to mobile users.
There are some known technologies to allow the benefit 10 of enjoying downloaded audio and/or video content which are however unsuited for mobile applications, notably the following.
Streaming 15 Streaming technologies enable the seamless transmission of audio or video content over telecommunication networks. Their main functions are to compress, transmit, decompress, buffer and present audio or video content on user devices. They are often referred to as Codecs and many versions exist such as for video: 20 DivX, MPEG4, WMV and MOV; for audio: MP3, WMA and AAC; and mobile: 3GP and H.264.
Streaming works well with fixed broadband telecommunication networks in combination with PC's. The fixed broadband networks have a much higher average performance, less latency 25 and good quality of service. PC's have enough computational power to decompress the data at high speed.
For mobile applications streaming does not provide an adequate solution because the transmission speed of the average mobile network is low and mobile computational power is limited. 30 The waiting time for buffering the audio and/or video content can be long, whereas the presentation may be interrupted and the visual quality is usually poor.
Multimedia Messaging Service 35
Multimedia Messaging Service (MMS) is a method to send a multimedia message via mobile devices. It is an extension of the well-known SMS services and is used to send pictures, audio or short video's from a mobile device to another mobile device. 40 The advantage of MMS is that the message is received directly after it is sent. Disadvantages of MMS are that it does not of- 3 fer audio or video streaming solutions, the size of the data content is limited, and the user costs are high. The implication is that audio or video messages take a long time to transmit, are short and expensive. MMS furthermore does not provide a so-5 lution for casting audio or video content to user groups.
It is an object of the invention to address one or more of the above mentioned problems and to provide a method and system for transmitting audio and/or video data to at least one mobile device, which can be enjoyed when played back by said mo-10 bile device at high quality.
In accordance with the invention a method and system are proposed having the features of one or more of the appended claims .
The system of the invention has in a first aspect the 15 features that the at least one server is embodied with a scheduling module for repeatedly scheduling a casting time in which the audio and/or a video content is available for downloading through the Internet.; and that the at least one mobile device is arranged to synchronize with the scheduling module and to re-20 peatedly connect to the at least one server during the scheduled casting times for downloading during each such separate connection at least part of the audio and/or video content at transmission rates that are available during said separate connections, and to continue making such connections until the 25 downloading of the audio and/or video content is complete.
The system of the invention thus is capable of providing high quality audio and/or video presentations on mobile devices, making it possible to distribute (cast) and present audio and/or video content at predetermined times to single or multi-30 pie mobile devices. The striking advantage of the system of the invention is that the audio and/or video content can be transported over any type of (low performance) mobile telecommunication infrastructure, without compression technology being required, and that the resulting playback on the mobile device 35 still is of high quality.
The advantages of the invention particularly come within reach by implementing this system preferably with a mobile device that is arranged with a memory and is programmed to store in said memory the downloaded parts of the audio and/or video 40 content until it is complete.
When the audio and/or video content is completely 4 stored in the memory of the mobile device, there are several options available for playing back the stored content. It may for instance be desirable that the user selects this playback time simply by pressing the playback button. Another possibility may 5 however be that the mobile device is equipped with an automatic play facility for playing the downloaded audio and/or video content when it is complete and/or when the time of day equates with a preselected playtime.
The system may suitably be equipped with a mobile de-10 vice that is arranged to erase the downloaded audio and/or video content when it has been played. This arrangement is particularly desirable when the downloading and enjoying of the audio and/or video content is subject to payment. In that situation it may also be preferable that the at least one server has an au-15 thorization module for authentication of the at least one mobile device and granting it access to the audio and/or video content. The system of the invention may then be arranged with a requirement for the mobile user to subscribe to a distribution channel (category of audio or video content) of their preference, and to 20 determine the presentation condition or times. The provider will then select the audio and/or video content and automatically distribute the content from the central server, making beneficial use of the network transmission latency.
The invention will hereinafter be further elucidated 25 with reference to an exemplary embodiment of the system and method for transmitting audio and/or video data according to the invention.
In the drawing: -figure 1 shows a schematic drawing of the system of 30 the invention; -figure 2 shows a general first flow sheet of a first part of the method of operation of a server and a mobile device of the system of the invention; and -figure 3 shows a general second flow sheet of a second 35 part of the method of operation of the server and mobile device of the invention.
It is expressly remarked that the exemplary embodiment which in the following is used to elucidate the invention, qualifies as a embodiment having several options that are not nec-40 essarily required in a basic type of system in accordance with the invention. The disclosure of the exemplary embodiment defi- 5 nitely teaches many options that can be added to any system of the invention, in order to gain advantages that are not immediately apparent to the artisan and that may warrant separate patent protection.
5 In this extensive exemplary embodiment the system preferably has the following options : • The mobile device has a mobile data subscription and can receive HTTP(S) data.
• The mobile device has software installed that can play au- 10 dio or video content.
• The mobile device has installed software enabling it to operate in accordance with the method of the invention.
• The mobile device is registered on the central server.
• The mobile user has selected one or more distribution chan- 15 nels on the central server to receive a certain category of audio or video content at predetermined times.
• The central server can authenticate and authorise mobile devices .
• The central server possesses a timing module for all chan- 20 nels to manage the distribution times and presentation ti mes on the mobile devices.
• The central server makes specific audio or video content, available for each distribution channel.
25
The method steps that are applied in the system of the invention are as follows: • The mobile device A sets up an Internet connection.
30 • The mobile device connects and authenticates to the central server B (see figure 1 and 2: step 1).
• The central server B authorises the mobile device A to synchronise with the timing module and download specific audio or video content (see figure 1: step 2 and figure 2: steps 35 4, 5, 6) .
• The mobile device A synchronises with the timing module 1.3 on the central server B (see figure 1: step 3 and figure 2: steps 7 and 8).
• The mobile device A downloads the audio or video content 40 that has been made available with HTTP(S) (see figure 1: step 4 and figure 3: steps 1-8).
6 • The audio or video content will be stored on the mobile device A and will playback the content at a predetermined time or condition (see figure 3: step 9).
5
In summary notable advantages of the method and system of the invention are: • that it can be applied with any type of (low performance) 10 mobile telecommunication network without, loosing audio or video quality.
• that it can be applied on all mobile phones with limited processing power as no decompression is required.
• that the presentation time of audio or video content can be 15 precisely determined.
• that each channel and recipient can be provided with the same audio or video content.
• that an unlimited number of channels can be implemented.
• that it can be combined with coding and decoding technology 20 to optimise transmission performance.
A more detailed description of the figures follows hereinafter.
Figure 1 shows a preferred embodiment of the system for 25 transmitting audio and/or video data according to the invention, in which at least one mobile device A, preferably a cell phone is employed as well as a central server B. The mobile device A. is required to have capability to access the Internet and communicate with the central server B.
30 The central server B. preferably has a content management module 1.1, an authorization module 1.2, a timing module or scheduling model 1.3, and may further employ modules for registration of channel selection 1.4, and other facilities 1.5 -1.6.
35 At a certain point in time the mobile device A may call in step 1 for specific audio and/or video data from the central server B. In reply thereto the central server B replies in step 2 with information relating to a poll frequency, the URL of the requested data, the casting time of the data, and any further 40 information that may be of interest.
Figure 1 shows that there may also be a further content 7 server C which can be used for casting the concerning data. When the casting time has arrived, the mobile device A polls for the data in step 3, and the concerning data is then downloaded in step 4 from the content server C to the mobile device A.
5 Figure 2 and figure 3 respectively provide a flow sheet de tailing the execution of operations by the mobile device A and the central server B.
With reference first to figure 2, in step 1 the mobile device A sends out a request for information, therewith also car-10 rying a unique identification of the mobile device A. In a waiting loop, comprising steps 2 and 3 the mobile device A monitors whether a response from the server B is received. If not, step 1 requesting information to the central server B is repeated. In the meantime server B processes the request from the mobile de-15 vice A in step 4, obtains the required information from a central database in step 5, and sends in step 6 the required information to mobile device A. This information pertains to the poll frequency of the data, the URL where the data is located, the starting time of casting the data, the download time etc.
20 Step 7 in figure 2 signifies a check whether the poll-time is less than the download time. If this is the case then the data is downloaded as explained further hereinafter with reference to figure 3. If not, then mobile device A awaits according to step 8 for the next casting of the requested information.
25 Figure 3 concerning the downloading of the requested data first shows a first step 1 at which the mobile device A waits for the expiration of the download time. Then in step 2 the mobile device A requests for the data and the receipt of such data is monitored in a waiting loop signified by blocks 3 and 6. Step 30 4 pertains to the central server B receiving the request from the mobile device A, and step 5 signifies the sending of the requested data to the mobile device A. Same is received at the mobile device A at the applicable casting time in step 8, and played back in step 9 at the desired playback time. Thereafter 35 the program of the mobile device A returns to step 1 in figure 2.
