Abstract

A method and system for programming a set-top terminal in a cable television system includes automatically launching a boot code object from the read-only memory of the set-top terminal when the terminal is powered or reset. The boot code object will automatically identify the next required tier of programming, i.e., a base platform code, and acquire and implement that base platform code. The base platform code may be acquired from the memory of the set-top terminal or downloaded from a data transport stream provided over the cable television system. Once the base platform code is executing, the boot code is terminated. The base platform code then automatically locates and acquires the operating system object and any other resident applications of a native suite. Again, the native suite including the operating system may be pulled from the memory of the set-top terminal or downloaded from the cable system. The base platform code authenticates the native suite and then launches the native suite to provide full set-top terminal functionality.

Description of the invention (2) Provide users Extra paid channels. It can also provide paid events and video optional programs through the online storage network. Digital signal receivers are programmed to provide these and other services to users. However, cable companies' services are not limited to providing television programs. Some cable companies provide Internet access and e-mail via their wired networks, which are faster than traditional telephone lines. In the future, it is expected that more and more services will be provided through the wired network, including even basic telephone services. Therefore, each home or office will have a single signal connection to all data servers via a wired network. When a new digital signal receiving terminal is added to the wired network, it must be initialized. In order to initialize the digital signal receiving terminal, the terminal must be provided with the required programming to allow it to operate in a specific wired network, where the terminal is connected to the specific network and provides the user with a fee Services. In addition, when the wired network and the services provided have evolved, the digital signal receiving terminal must also evolve at the same time to provide all the services of the wired network to users. The evolution of the digital signal receiving terminal is mainly related to the programming change or re-initialization of the digital signal receiving terminal. By upgrading the software and hardware of the digital signal receiver, the receiver can become more efficient and provide new services when the wired network is upgraded. In order to initialize the new digital signal receiving terminal and upgrade the program planning of the existing digital signal receiver users of the wired network, it is best to send the required program rules to its own wired network.

Description of the invention (3) Install or upgrade the digital signal receiver. This plant installation and upgrade is obviously very costly. A he adend is a device that allows operators of a wired network to broadcast television signals and provide other services through the wired network. The software provided to the user of the digital signal receiving terminal can also be broadcast from the headend via a wired network. However, the method of broadcasting the program plan from the headend to initialize and upgrade the digital signal receiving terminal will cause many problems. For example, users of digital signal receiving terminals may have different functions, different brands, and different models of digital signal receiving terminals. The software required to initialize and upgrade the digital signal receiving terminal of each brand and model is also different. Therefore, there is an urgent need for a method to match the appropriate .program planning code to the function of the digital signal receiving terminal to be initialized or upgraded. In addition, the initialization process needs to be automated to avoid or reduce the time required for technicians to install digital signal receivers, upgrade or reinitialize digital signal receivers. SUMMARY OF THE INVENTION The object of the present invention is to meet the above and other needs. In particular, an object of the present invention is to provide a method and mechanism for matching an appropriate programming code to be broadcasted through a wired device to a function of a digital signal receiving terminal to be initialized or upgraded. In addition, another object of the present invention is to automate the initialization procedure so as to avoid or reduce the time required for a technician to install a digital signal receiving terminal and upgrade or renew the digital m receiving terminal.

The word * boot code * in this article contains the minimum code required to complete this function. The programming of the digital signal receiver of the present invention includes two specific stages. The first stage is the initial programming of the digital signal receiver. The second stage is the upgrade program planning or digital signal receiver re-initialization after the digital signal receiver is provided. The initial planning of a digital signal receiver is usually performed by a cable system operator after purchasing a digital signal receiver. Because each wired network is designed and established by different service providers at different times, each wired network has a different design, structure, and object code. In addition, specific services may vary with different wired networks. Therefore, in order for the digital signal receiver to function properly in the environment of a service provider's wired system 'and to provide a specific service group for a specific service provider, the digital signal receiver must therefore be programmed or "initialized". The initialization procedure of the digital signal receiving terminal of the present invention will be described in detail below. In order for the digital signal receiving terminal to be initialized (i.e., to receive and use the provided initial programming plan), it is necessary to have some basic programming plan to indicate how to receive and adopt the initial programming plan. The basic program specifications in this article are called boot codes. As mentioned above, the boot code is resident in the permanent memory of the digital signal receiving terminal. It is best installed in the read-only memory at the factory and cannot be changed once installed. As shown in FIG. 1, the present invention provides three different program specification levels.

Description of the invention (9) or classification 'It executes or obtains control of the digital signal receiving terminal at different stages of initialization and terminal operation, respectively. See Figure 1. The first type of code is the boot code (i). The boot code is preferably located in the read-only memory of the digital signal receiving terminal, and it can also be located in the flash memory. When the power-on code (1) is executed, the digital signal receiving terminal cannot provide any service to the user. The function (2) of the boot code (1) is to search the data transmission stream from the headend device in order to configure, obtain and execute the basic platform code (3). 'The basic platform code (3) is the next level of programming. . The boot code (1) is used to authenticate the basic π code after downloading the basic platform code. The boot code (1) preferably authenticates the base platform code each time the base platform object (3) is executed. When the basic platform code (3) is executed, the execution of the boot code (1) is suspended, and the control of the digital signal receiving terminal is passed to the basic platform code (3). The basic platform code (3) can be factory loaded (fact〇ry 1〇aded). However, under the principle of the present invention, the basic platform code (3) is preferably transmitted from the wired head end to the digital signal receiving end during the initialization of the terminal. It is suitable for the operator of the wired system to customize the basic platform code (3) to provide the optimized operation of the specific wired system where the digital signal receiving terminal is located. The basic platform code (3) is preferably transmitted through a cable factory as an out-of-band transport stream.

The second function is to control the download of code objects at the next level (5), that is, the target operating system (0 / S) and the resident application (6). The basic platform code (3) does not support other functions of the digital signal receiving terminal when allowing users to watch TV. However, the basic platform code (3) can obtain, authenticate, authorize, and execute the third and final level programming objects (e.g., 0 / S) (5). The third level programming (operating system and resident application (6)) provides other digital signal receiving terminal functions of the wired system. The operating system (◦ / S) is a typical code provided by a second party (such as Microsoft's WinCETM), which can access all authorized digital signal receiving terminal functions through resident applications. The operating system usually utilizes additional built-in code modules provided by the manufacturer of the digital signal receiving terminal to enable the operating system to work with a specific digital signal receiving terminal. The additional built-in code modules provided by the manufacturer It serves as the interface between the operating system and the specific hardware of the digital signal receiving terminal. A resident application is a computer program that can run in a digital signal receiving terminal under the operating system. The resident application works with the operating system to provide the digital signal receiving terminal with functions other than watching TV. The basic package (n a t i v e s u i t e) is a specific software application group (which includes the operating system and different resident applications) to provide the functions required by the digital signal receiving terminal.

As shown in Fig. 2, when the digital signal receiving terminal is powered on for the first time, or when an appropriate reset signal is received, the power-on code is executed (2 2 9). The boot code must first determine whether or not the digital signal receiving terminal must obtain the basic platform code. To this end, the boot code first checks the basic platform code in the flash memory, checks the last known carrier frequency (LCK) frequency in the control channel from the headend, and the identification of the subsidy management information provider (Entitlement Management Message Provider Identification, EMM Provider ID) (201, 202). If any of the following three conditions are found, the boot code will determine that the basic platform code must be obtained and will look for out-of-frequency channels or in-frequency channels where the basic platform code may be located. If (1) the basic platform code, the last known carrier, and the EM Provider ID are not stored in the flash memory, (2) the basic platform code in the flash memory cannot pass the authentication check, or (3) Non-volatile memory means that if a control channel (such as an out-of-band channel) must be found, the boot code must obtain the basic platform code.

If the basic platform code is not loaded in the flash memory, then the boot code will be loaded from the out-of-band transport stream (203, 2 04'2 0 7). However, it must be successfully authenticated before writing to the flash memory (206, 205). When the authenticated base platform code is executed, the boot code passes control to the base platform (2 1 1 ′ 2 2 8). If the basic platform code does not pass the authentication check (205), the failed basic platform code (2 0 8) 'is deleted and the counter 値 used to track the number of attempts to obtain and authenticate the basic platform code is decremented. If the counter is lower than the preset number of receivable attempts', the basic platform code (207) will be downloaded again. Or, if the preset acceptable number of attempts to download the basic platform code is exceeded, the digital signal receiving terminal will send a message to the headend to request a service call (210). Under the principle of the present invention, the boot code configures basic platform objects that use a boot code message or a boot code control message (boot — code_message), where the message is periodically transmitted in an out-of-band transport stream (2 0 4 )in. The use of the boot code control message is detailed below. When the boot code determines that a basic platform object must be downloaded, it will first look for a control channel. A table for broadcasting the possible carrier frequencies of the control channel is included in the boot code. These frequencies can be in-band or out-of-band. The power-on code will cause the digital signal receiving terminal to tune each channel sequentially until K securely controls the channel and acquires an earner lock.

The control channel is a data packet stream (stream 〇fdatapackets) 'can be received and used by the digital signal receiving terminal. In order to broadcast several different objects at the same time, the headend divides the objects to be transmitted through the control channel into packets. . Then, the packets of these different objects to be transmitted will be spread together or time-multiplexed, so that many objects can be transmitted at the same time. Each specific object's packet will have a common packet identifier or ~ PID 〃. Therefore, The digital signal receiving terminal can identify the packet of the object you want to obtain. After determining all the packets of the PID, the digital signal receiving terminal can reassemble the complete object from the group of packets with a specific PID. According to the present invention, the digital signal receiving terminal can obtain objects and package them at any progress stage until all Until the packet is downloaded. For example, the digital signal receiving terminal can load the first packet with PIDX. The packet may be a packet 50 out of 100 packets labeled PIDX. Then the digital signal receiving terminal Continue to collect packets 51 to 100 with PID X, and then receive packets 1 to 49. When all 100 packets are obtained, the digital signal connection & terminator can reassemble the object cut by the packet The headend may need to broadcast multiple objects at the same time, because there may be different types or types of digital signal receiving terminals in the household.

Here you can search multiple EMM P i Ds at the same time to reduce the EMM verification time and the time required to find a matching boot code message. If all the EM Providers 1 D in the c AT of p ID 1 have been checked and the matching platform identifier cannot be found, the boot code will return to the carrier frequency table in order to find another control in another carrier frequency Channel. When another frequency with the control channel is identified, the boot code will select PI D 1 and repeat the above procedure. This step will continue until the platform identifier of the boot code message matches the platform identifier of the boot code. When the boot code finds a boot code message with a matching platform identifier, the boot code will select the download PID (DL PID) specified by the matching platform identifier. Download PID (DL PID) is a packet identifier with a code object (such as a basic platform code object), where the object is a digital signal receiving terminal for a platform identifier with a boot code message.
