Description

METHOD FOR A SET TOP BOX TO DETERMINE ITS ENVIRONMENT
FIELD OF THE INVENTION
The present invention relates to cable set top boxes and, in particular, to self- determination of usage environment based on channel map characteristics or configuration parameters.
BACKGROUND OF THE INVENTION
It is desirable for a cable operator to install a common set top box (STB) for both residential and commercial/hospitality use. The STB may have different behaviors for the two environments, so it (cable STB) needs some mechanism for determining how it is being used. The cable headend may not have a "standard" method for configuring the STB for the alternative uses. The present invention proposes alternate selection methods using existing available configuration data that can be used in the absence of a "standard" headend configuration message for selecting an operating mode.
A cable operator may have different hardware models or firmware loads that can be used for different behaviors in different environments. However, the cable operator may want to maintain a common stock of set top boxes with a common firmware load to reduce complexity in their ordering system and warehouse.
Standard signaling messages from a cable headend to a set top box exist for setting authorizations, channel maps, locations, etc. But there may be no existing method in the standard configuration messages for the headend to signal the STB if it is installed in a residential or a commercial environment. Adding such signaling to the headend would involve the headend manufacturer and possibly other licensing agencies, and may take a long time or considerable expense.
SUMMARY OF THE INVENTION
The present invention is directed to a cable set top box to allow the set top box to determine if it is operating in a residential or commercial/hospitality environment in the absence of a "standard" headend configuration message. The result of the determination is to set its (cable set top box) behavior accordingly. While the invention is described in terms of a cable set top box, it is not so limited and may be used for any set top box such as satellite or telco set top boxes.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The cable operator will typically have some configuration parameter that can be used to distinguish between STBs operating in a residential or commercial/hospitality environment. The present invention uses one or a combination of different existing configuration parameters to allow a common software load in a common hardware platform to be configured to operate with the proper behaviors for its target environment. This includes:
A channel map ID number of a specified value or in a specified range. There will typically be multiple channel maps available for a cable STB based on the customer's subscription level. If a specific channel map ID or a range of IDs are defined for commercial/hospitality use, the STB can tailor its behaviors for commercial/hospitality use if it is configured to use one of the channel maps in this defined range. (Fig. 1) The channel map could contain a channel number or range of numbers that is unique to the commercial / hospitality environment. It could be a hidden channel that the STB is not allowed to tune. If that channel number exists in the channel map (or any number in the defined range), then the STB can tailor its behaviors for commercial/hospitality use. (Fig. 2)
A cable channel map will typically contain a Source ID which is a unique number that identifies a network or program. There is a national Source ID registry, but a block of Source IDs is reserved for use by the cable operator. The cable operator could configure the channel map(s) used by the commercial STBs to contain a defined Source ID or a range of defined Source IDs. If the channel map contains that Source ID (or any Source ID in the defined range), then the STB can tailor its behaviors for commercial/hospitality use. (Fig. 2)
Similarly, the channels in a channel map will be assigned a name that is typically associated with the network or programming. The cable operator could configure the channel map(s) used by the commercial STBs to contain a defined channel name. If the channel map contains a channel with the defined name, then the STB can tailor its behaviors for commercial/hospitality use. The defined name need not be the full channel name, but could be a smaller text sequence embedded in a longer channel name. (Fig. 2)
- The channel map could contain a channel that points to a specific frequency (or a range of frequencies) that only commercial/hospitality STBs will use. That frequency need not be actually tunable. It could be a dummy frequency on a hidden channel that the STB is not allowed to tune. If that frequency exists in the channel map (or any frequency in the defined range), then the STB can tailor its behaviors for commercial/hospitality use. (Fig. 2)
The above method uses configuration parameters that are easily targeted to specific set top boxes. There are other configuration parameters that could be used, but they would be more difficult to use given that these parameters may be harder to target to STBs installed in different environments. These parameters include (but are not limited to): A timeout value
A location ID number
A maximum value for a location error
A text string for an on-screen message
A particular modulation mode or MPEG program number present channel map.
It is possible that the cable operator will want to change the current residential or commercial /hospitality operating mode of the set top box, or it could have been misconfigured originally and need to be reconfigured for the proper environment. The set top box will need to monitor for any changes in the configuration and dynamically change its behavior as necessary. (Fig. 3)
Upon each power cycle or reboot, the set top box will need to determine its proper behavior. This can be accomplished either by a flag saved to non-volatile storage when the operating mode was determined during the original configuration process, or the set top box could recheck its saved configuration for the commercial mode trigger as defined for this product. (Fig. 4)
Referring to Fig. 1, at 105 the cable operator sends a standard configuration message to signal the cable STB via the headend. For example, the cable operator may send a standard configuration message with a channel map ID. This message is received by the cable STB at 105. At 110 a determination is made if the channel map ID is in a defined range that specifies commercial operating mode. If the channel map ID is in that defined range then at 115 the cable STB is configured to operate in commercial/hospitality mode. If the channel map ID is not in that defined range then at 120 the cable STB is configured to operate in residential mode.
Referring to Fig. 2, at 205 the cable operator sends a standard configuration message to signal the cable STB via the headend. For example, the cable operator may send a standard configuration message with a channel map ID. This message is received by the cable STB at 205. At 210 a standard configured channel map is loaded by the cable STB. At 215 a determination is made if the channel map contains the predefined "trigger" (channel, Source ID, channel name, frequency). If the channel map contains the predefined "trigger" then at 220 the cable STB is configured to operate in commercial/hospitality mode. If the channel map does not contain the predefined "trigger" then at 225 the cable STB is configured to operate in residential mode.
Referring to Fig. 3, the cable STB is operating normally in either mode but the cable operator wants or needs to reconfigure the cable STB. At 305, the cable operator sends a standard configuration message from the head end to signal the cable STB that it needs to update its configuration. At 310, a determination is made if the updated configuration contains a commercial/hospitality "trigger" (channel map ID, channel, Source ID, channel name, frequency). If the updated configuration contains a commercial/hospitality "trigger" then at 315 the cable STB is configured to operate in commercial/hospitality mode. If the updated configuration does not contain a commercial/hospitality "trigger" then the cable STB is configured to operate in residential mode.
Referring to Fig. 4, the STB had its behavior configured based on a previous environment determination. At 405 the STB is rebooted by any mechanism (power cycle, headend message, etc.). At 410 a determination is made if the STB was previously configured for a commercial/hospitality environment. If the STB was previously configured for a commercial/hospitality environment then at 415 the STB is set to continue to operate in the commercial/hospitality mode. If the STB was not previously configured for a commercial/hospitality environment then at 420 the STB is set to operate in the residential mode.
It is to be understood that the present invention may be implemented in various forms of hardware, software, firmware, special purpose processors, or a combination thereof. Special purpose processors may include a system-on-a-chip (SoC), application specific integrated circuits (ASICs), reduced instruction set computers (RISCs) and/or field programmable gate arrays (FPGAs). Preferably, the present invention is implemented as a combination of hardware and software. Moreover, the software is preferably implemented as an application program tangibly embodied on a program storage device. The application program may be uploaded to, and executed by, a machine comprising any suitable architecture. Preferably, the machine is implemented on a computer platform having hardware such as one or more central processing units (CPU), a random access memory (RAM), and input/output (I/O) interface(s). The computer platform also includes an operating system and microinstruction code. The various processes and functions described herein may either be part of the microinstruction code or part of the application program (or a combination thereof), which is executed via the operating system.
It is to be further understood that, because some of the constituent system components and method steps depicted in the accompanying figures are preferably implemented in software, the actual connections between the system components (or the process steps) may differ depending upon the manner in which the present invention is programmed. Given the teachings herein, one of ordinary skill in the related art will be able to contemplate these and similar implementations or configurations of the present invention.
