Description
"SYSTEM AND METHOD FOR TELECOMMUNICATION"
The present invention relates to a system and method for telecommunication, specifically interactive telecommunication, the system comprises principally: at least one transmission medium; a user apparatus connectable with the transmission means; 0 - a server apparatus connectable with the transmission means for exchange of information with the user's device; and a coupling means for connecting the user's apparatus and the transmission medium, as desired. In technology, these systems are understood,
However, communication between the user's device and the server is often not possible as a result of differences in the ways in which the devices are communicated. The object of the present invention is to provide a means that allows interactive communication along any means of transmission selected between the devices of the user of various classes and a server apparatus.
It is also an object of the present invention to provide a means for carrying out a minimum number of functions to enable communication between the user's apparatus and the server apparatus. In accordance with the present invention, there is provided a system characterized in that the coupling means comprises a means for controlling the user's apparatus based on the information of the apparatus
_, _ server and to control the server apparatus based on
the information of the device of the usury; and means for creating and carrying out communication with the server apparatus and the user's apparatus. In addition, this system according to the present invention is characterized in that the means of
The coupling comprises a "Set-Top" unit (Set-Top unit) and a physical medium converter, in which the means for controlling the user's device are present in the "Set-Top" unit and mainly comprise a program for a dynamic process loaded down from the
server apparatus and stored in a RAM memory, in which the means for creating the communication is a program for a static process stored in a ROM memory of the unit named "Set-Top". As a result of the characteristic properties
mentioned above of the system according to the invention, a two-level adjustment is achieved, namely the adjustment of the "Set-Top" unit to the transmission medium by means of the physical medium converter and the adjustment of the communication between the Unit "Set-Top" and the server device through programs of the "Set-Top" Unit that originate from the server device. In accordance with the present invention, an alignment of the "Set-Top" Units can be developed as commercial products. Likewise, in order to promote the development of interactive digital audio-video services, the manufacturers of the "Set-Top" Unit will be left as free as possible to compete in the supply of these "Set-Top" Units. Therefore, only a minimum set of functionalities is defined in order to be incorporated into a standard. This game can be seen as an "intelligent access door" for interactive digital audio-video services. The invention will now be explained in detail with the following description of a preferred embodiment of the invention with reference to the accompanying drawings, in which: Figure 1 is a schematic representation of the configuration of elements in the system on both sides of a means of transmission;
Figure 2 is a schematic representation of the "Set-Top" Unit shown in Figure 1; Figure 3 is a schematic representation of the physical medium converter shown in Figure 1. The portion of a telecommunication system in accordance with the present invention shown in Figure 1, mainly comprises: a "Set-Top" Unit 1; - a physical medium converter 3; - a connection channel 9; a transmission means 4; and a server apparatus 2. The coupling means are formed by the "Set-Top" Unit 1, together with the connection channel 9 and the physical medium converter 3, the coupling means forming a connection between the user's apparatus 10. and the transmission medium 4. The transmission means 4 is a connection between the coupling means and the server apparatus 2, the server apparatus 2 has a configuration similar to the unit "Set-Top" 1, which is emphasized with the specular line 5 and the representation of the converter 3 of physical medium through the lines of dashes. The "Set-Top" Unit 1 contains a memory space divided mainly into three parts. The "Operating System" is placed in the first part 6 of the memory space and the "Operating System" controls the communication between the physical apparatus of the "Set-Top" Unit 1 and the program for static or dynamic processes that run in the "Set-Top" Unit 1. It should be noted that an application program interface (API) can run between the Operating System and the programs for static or dynamic processes. In the case of interactive communication, for which the telecommunication system according to the present invention is particularly appropriate, the Operating System of preference is Real Time, Multiple Tasks, of Object Oriented type and comprises a minimum number of instructions basic The operation system mainly handles memory management and communication between processes through "message handling". The second part 8 of the memory space contains a program for static processes, which ensure the correct operation of the "Set-Top" Unit 1. The third part 7 of the memory space contains programs for dynamic processes, which ensure correct communication with the server apparatus 2 selected by the user. Since the server apparatus 2 has a configuration similar to the "Set-Top" unit 1, the corresponding parts of the memory space of the server apparatus 2 are similarly represented by 6 '. 8 '. V, respectively. During the initiation of communication between the "Set-Top" Unit 1 and the server apparatus 2, the dynamic processes 5 are sent to the "Set-Top" Unit 1 via the server apparatus 2. Therefore, the initiation of the communication can be represented by the following sequence: __ "___ 1. Initiation by the user. 10 2. The related static processes become active in the "Set-Top" Unit 1. 3. The static processes create a connection with the user's device 10 and with the server device 2. 15 4. The static process sends the related information regarding the "Set-Top" Unit 1 in the form of an "identification format" to the 2 server device. This identification format declares the operating capabilities of the "Set-Top" Unit 1 to the server device
2 at the beginning of the session. These operating capabilities are related to the size of the available memory for dynamic processes, the type of the screen impeller or the type of other user device, the type of remote control, who are available the additional programs for static processes (namely the I / O impeller, and / or a board impeller). 5. The static process in the appliance 2 server assembles the programs for dynamic processes appropriate for the Unit "Set-Top" 1 present, where the appropriability is determined by the information in the "identification format" assuming the 2 server apparatus certain parameters for the "Set-Top" Unit 1 present in the case, when the "identification format" contains insufficient information, where these assumed parameters, for example, are set as a result of normalization. These parameters preferably comprise a minimum normalized screen driver or other adjustment unit for a user apparatus, a minimum normalized memory size for dynamic processes, a minimum normalized physical user control being an elementary remote control, without any additional optional programs for static processes. These minimum performance requirements are predetermined, for example: the minimum screen impeller in the form of teletext overlay; minimum memory size for dynamic processes, for example, 4Mbits; minimal physical user control, preferably a four-button "cursor" plus a "select" / "no" button, where these "buttons" do not need to be physical buttons.
6. The server apparatus 2 sends the programs for the dynamic processes required by the Unit "Set-Top" 1 to the Unit "Set-Top" 1, where these programs are stored in the memory space of the
Unit "Set-Top" 1. The dynamic processes in the Unit "Set-Top" 1 and the dynamic processes in the device 2 server communicate to regulate a stream of data between the
^ Unit "Set-Top" 1 and the appliance 2 server. Figure 2 is a schematic representation of the configuration of the "Set-Top" Unit 1 comprising: a processor 11; a memory space formed by a ROM memory 12 and a RAM memory 13; and 15 - a port 14 for data entry and exit. f- Programs for static processes are present in the 12 ROM memory and are copied to the RAM memory 13 when the need for this process arises
static. The programs for static processes that are in the "Set-Top" Unit 1 mainly comprise programs for controlling the operation of an adjustment unit for a user's device similar to a screen driver, a keyboard driver or a port driver.

However, if existing displays only provide an extremely embedded and elementary mechanism for the coating, a screen driver that controls the operation of the device may be needed.
^ presentation. This process will only remain active
as long as a dynamic process does not adopt it. Similarly, a keyboard driver can control the operation of a terminal. An I / O port driver, for example, can control the operation of a connected game console. 5 A Resident User Interface process is necessary when connected to the "Set-Top" Unit 1. This
"'- process is then automatically started for which 13 RAM is loaded into the memory where this process should be minimal.In the case of a network application, this process 0 only allows the unit" Set-Top "1 connect with 1 or a very limited number of devices 2 servers or only with the navigation systems supplied by the network provider (level 1 in the terminology of the United States) Once the unit "Set-Top" 1 5 has access to the server 2 device or the navigation system of the network provider, the last uploads the application software down to the beginning of the session, including a user interface. An active Resident User Interface process is then placed on hold and only becomes active again when the session is terminated due to any reason. This mecanaismo allows service providers to model their user interfaces according to their needs (and also
'.s' compete for better user interfaces.
RUI functionality is in any case very simple; it only allows the user to connect to the server devices that will have their own user interfaces. It should be noted here that the resident user interface processes could also be used to allow the
definition of some functions, such as the user profile, the basic or domestic profile, etc. , - The static process to control the reaction to calls is activated, when the user has selected a server device 2 that he wishes to connect to, or
when, for example, a first access to a network and a connection to the network is required. The process that handles the call is a process that handles all network and protocol tasks (for example, SDH / ATM) in order to establish the connection. If all messages to and from the network are handled by this process, it will work as long as the connection to the network (the session with the device 2 server) is active. Alternatively, when the downloaded software communicates with the network directly (and the upper layer with respect to the protocol with the server apparatus), the process that handles the call is terminated at the time the call is established and the connection has been established. Intermediate scenarios are possible where the process that handles the call in
, ^ _ all times it handles the lower layer protocols and
network signals, while downloadable application software handles end-to-end protocols. The process that handles the call depends on the protocols of the selected network. In the case of digital telecommunication
For example, interactive MPEG 2 coding can be selected for digitsal A / V encoding, preferably as a standard. If the A / V decoding process is carried out by a piece of dedicated hardware, an administrator is required to
resident A / V MPEG decoder 2. If microprocessing operation allows it, however, it could, however, be visualithe down load of the A / V decoding chart in the software. A program that controls the process is needed
remote control to carry out at least r- remote control operations. It could also include the person responsible for the process for initial conditional access (including a smart card interface driver). In addition, certain 5 resident "accounting" functions could be carried out through this process, monitoring user spending. Similarly, the downstream application software of the resident user interface could adopt these functions in which case this process of remote control operation will be deactivated and will only be reactivated when the session is terminated. to any reason. A resident program for managing "load down" handles the processes in memory space 7
for dynamic processes. It is activated when the user has selected a server device 2 to connect to it. The application software is then loaded down from the server apparatus 2 to part 7 of the memory space containing the programs for
dynamic processes, after which the control is delivered to this process. The down-load process always works when the dynamic process is active. When the last dynamic process is complete, the control is returned to the user interface process
resident.
The programs for dynamic processes that originate from the server apparatus 2 are stored in the RAM memory 13, from where these dynamic processes can function in the processor 11. The dynamic processes in themselves are not a unit "Set-Top" 1. All dynamic processes originate from several devices 2 servers (for example, navigation, service providers or content providers). The dynamic processes are loaded into the "Set-Top" Unit 1 through the down-load process that then notifies the operating system of its presence. A down-load process can then initiate and carry out its functions by, for example (and if necessary), communicating with the static processes through the operating system. These dynamic processes are, for example, a modified user interface, monitor functions, end-to-end protocols, etc. Dynamic processes can use static processes when necessary. The operating system and the down-loading process are preferably capable of accommodating any number of dynamic processes, where the number of simultaneously available downstream load processes will be limited only by the memory capacity (RAM 13). Preferably, it is possible that there is more than one dynamic process loaded downward, for example, if the user stops a dynamic process to make the other work, resuming the first one after completing the second one. For example, a user can stop his "video on demand" movie in order to reserve a flight to where the movie was filmed. The download process is active and ensures that only one process has access to the video / audio decoder hardware. Preferably, the "Set-Top" Unit 1 contains the foing interfaces: network interface (downstream and backward channels): RGB / PAL / SECAM / NTSC interface; analog / digital audio interface; and UHF interface. As an option, an interface can be placed between the MPEG 2 demultiplicator and the video and audio decoders. Likewise, a 1/0 interface (data) can be added. The user interfaces of control / smart card for remote control are not specifically mentioned here. For the network, logical protocols of ATM interfaces (format and signals - including call establishment) are used independently of the physical medium, either for the downstream channel or for the return channel, which may be different channels. In this case, an ATM adaptation layer (ALL) 5 is needed for signals. For the transport of audio-video data, an MPEG transport stream can be used.
Two MPEG 2 transport packages could then be contained in eight AAL 5 cells optimizing the upper one. The MPEG 2 system layer for transport streams provides all the necessary means for recovery of the source clock through timestamp mechanisms. Alternatively, it is possible to use an ALL 1 to transport the MPEG 2 transport stream containing an MPEG 2 transport packet in four AAL 1 calls.
^ An FEC above the AAL 1 stream is optimal as the C0 tests have shown, so that signaling with flags of a loss of the MPEG 2 transport packet (or even better a cell loss through the use of the Cell sequence numbering available in AAL 1) to the MPEG 2 decoder allows techniques that hide the owner's error that is hardly detectable by any observer. '""' The programs for dynamic processes, however, must be loaded downwards free of errors at the beginning of the session between the 2 server appliance and the 0"Set-Top" unit 1. In this case, the processing is not required. real time as isochronicity is not required unlike in A / V currents. Therefore, it is possible to use an ARQ type end-to-end recovery protocol. The Express 5 transport protocol (XTP), which is less complicated than the TCP / IP recovery protocol, can be used to provide this error detection mechanism. The RGB / PAL / SECAM / NTSC interface is intended to connect with a normal interface, which is also the case for analog / digital audio interfaces. A UHF interface can be used for old televisions, to which the current and most modern normal audio / video interfaces can not be connected. A 1/0 interface (data) that can be added optionally, is a transparent interface (bit stream) that allows the connection of other terminals, for example, a game console to the "Set-Top" Unit 1. In this In this case, the "Set-Top" Unit 1 is really an "intelligent access door" to interactive digital audio / video services. The schematic representation shown in Figure 3 of the physical medium converter 3 comprises: a converter 21 for the connection channel 9; - a converter 22 for the transmission means 4; and a connection between the converters 21 and 22 comprising the connection channels 25 and 26. The connection channel 9 between the "Set-Top" Unit 1 and the first converter 21 is usually not of the same class as the transmission means 4 between the second converter 22 and the server apparatus 2. The converter 3 has a modular configuration in the embodiment shown here, to allow a simple adjustment to the present transmission means 4 using another converter 22 in the converter 3. It is also possible to make the appropriate converter 3 for various means 4, 4 'of transmission, adding a converter 22 'represented by the dashed lines necessitating the use of a selector 24 which is provided at the connection between the converters 21 and 22, 22', between the connection channels 25 and 26. The channel 9 of preferably connection is of one type so that this side of the converter 3 does not need measures such as those that are taken on the other side
of the converter 3, to allow the variety of possible transmission means 4. ? = - The communication along the connection channel 9 between the physical media converter 3 and the "Set-Top" unit 1, for example, can be carried out with 0 SDH / Sonnet 155 Mbps. However, the output of the physical medium converter 3 to the "Set-Top" Unit 1 is subjected to certain minimum operating requirements, namely in terms of the Bit Error Rate (BER), regardless of the physical transmission means 4 that is used as an access network (coaxial cable, fiber cable, ADSL, etc.). As a result of this mechanism, the "Set-Top" Unit 1 is completely independent of the type of physical transmission means 4 used as the access networks. It is evident that the physical media converter 3 can be incorporated in the "Set-Top" Unit 1 even though they have been represented by individual elements in Figure 1 and Figure 2. In addition, the coupling means formed by the "Set-Top" Unit 1 or by the "Set-Top" Unit and the physical medium converter 3 can be incorporated in the user's apparatus 10 to form a unit therein.
