Each channel map is accompanied by a channel map identifier which identifies the source of the television transmission and a geographic identifier. The source of a television transmission is automatically detected by monitoring the radio-frequency spectrum allocations of telecast stations. The geographic area identifier is determined by comparison with a user inputted geographic area identifier. The channel map having a channel map identifier corresponding to the detected television transmission source and the user inputted geographic area identifier is downloaded and stored for future use.
What is claimed is: 1. A method for controlling a television tuner at a specific geographic location comprising the steps of:

All of the above-identified applications being incorporated herein by reference as though set forth in full.
Caption data decoding is known in the art and described in the following specifications, which are hereby incorporated by reference herein: Title 47, Code of Federal Regulations, Part 15 as amended by GEN. Docket No. 91-1; FCC 91-119; �CLOSED CAPTION DECODER REQUIREMENTS FOR THE TELEVISION RECEIVERS�; Title 47, C.F.R., Part 73.682(a)(22), Caption Transmission format; Title 47, C.F.R. Part 73.699, FIG. 6; �TELEVISION SYNCHRONIZING WAVE FORM�; Title 47, C.F.R., Part 73.699, FIG. 17 a; �LINE 21, FIELD 1 DATA SIGNAL FORMAT�; and PBS Engineering Report No. E-7709-C, �TELEVISION CAPTIONING FOR THE DEAF: SIGNAL AND DISPLAY SPECIFICATIONS�.
To successfully download the appropriate channel map, a Channel Map Decoder is required at the point of reception. FIG. 4 shows an electrical block diagram of a preferred embodiment of the Channel Map Decoder integrated into a conventional television receiver. Alternatively, the Channel Map Decoder may be integrated into a VCR or housed in a stand alone unit. A UHF/VHF tuner 38 is positioned at the front end of the Channel Map Decoder for passing a selected channel of the television transmission. The tuner 38, which can be any conventional tuner in the art, should provide amplification, downconversion and demodulation, as well as frequency tuning. The tuner 36 is coupled by an intermediate frequency (�IF�) amplifier 38 to a video detector 40. A base band video signal at the output of the video detector 40 is coupled to a television monitor 42 for presentation to the viewer. The tuner 36 is set by a signal from a microcontroller 44 to the desired channel number. A remote controller 46 is coupled to the microcontroller 44, typically by an infrared communication link, to provide viewer control of the television channels.
The format of the channel mapping information generated by the physical host comprises VBI encoded �data packets,� with each data packet being divided into one or more �data blocks.� Each data block is encapsulated with synchronization code, error detection code, and address code by means well known in the art. In some cases it may be preferable to encrypt or scramble the data packets. In the described embodiment thus far, each channel map would be packaged as a data block and all the data blocks transmitted as a single channel map packet. An exemplary data block for a channel map packet is shown in FIG. 5. The data block is arranged into a serial format of data bytes representative of a start code 52, a packet type 54, the number of blocks in the data packet 56, the block number 58, a channel map identifier 60, a channel map 62, a checksum 64 and a stop code 66.
The system distribution network described thus far is well suited to provide coverage for the majority of the nation. However, in more densely populated metropolitan areas, such as New York and Los Angeles, where the number of different zipcodes is extremely high, the bandwidth limitations may adversely impact the data repetition rate at which the source map packets and channel map packets can be transmitted. Accordingly, in these densely populated areas, the concept of a �logical host� is introduced to minimize the impact of the bandwidth limitations and reduce the potential for data redundancy. The logical host is an abstract or conceptual host responsible for serving channel map information to a particular group of viewers identified by the same HOSTID. In these densely populated areas, it is desirable to divide the city area into multiple groups, each served by a different logical host. The logical hosts could then be allotted between two or more physical hosts thereby reducing the volume of data that would otherwise be required if a single physical host were used. Conversely, a single national physical host can carry multiple logical hosts to numerous rural or sparsely populated areas thereby reducing the number of physical hosts required to serve the United States.
The Channel Map Decoder will continue to scan the RF spectrum in search of multiple logical hosts. When the tuner is tuned to KCET, channel 29 (see FIG. 1), the Channel Map Decoder will detect additional host schedule packets and record the current GCH bit, in this case the current GCH bit is set to a logic �1� for GCH number 28 (not shown). Accordingly, a second channel map pair can be established:
Further discrimination may performed by monitoring any XDS (�Extended Data Service�) data. Under the Extended Data Services proposed in the Recommended Practice for Line 21 Data Service, Electronics Industries Association, EIA-608 (drafts Oct. 12, 1992 and Jun. 17, 1993), the subject matter of which is incorporated herein by reference, additional standardized data may be provided in line 21, field 2 of the vertical blanking interval. This recommended practice includes two closed captioning fields, two text mode fields and the extended data services. The extended data includes, among other information, program name, program length, length into program, channel number, network affiliation, television station call letters, UCT (universal coordinated time) time, time zone, and daylight savings time usage. Accordingly, by utilizing the television station call letters, the Channel Map Decoder can determine the corresponding GCH number using the source map packet and establish additional channel map pairs in much the same manner as described above using the host schedule packets.
Turning to FIG. 16, an electrical block diagram of a preferred embodiment of the Channel Map Decoder is shown. Preferably, a single chip 8-bit microcontroller 200, hereinafter referred to as the �channel mapping microcontroller,� is used to implement the channel mapping function. The chip core is a microprocessor, such as a 68HC05CCV from Motorola with 512 byte internal Ram, 12 K byte ROM, and a VBI decoder. This chip can embedded into any VCR or television. Alternatively, the channel map decoding functions can be implemented and coded into the existing microcontroller in the VCR or television, provided the system has a VBI decoder.
Preferably, the main microcontroller 202 is also a 68HC05CCV from Motorola. In this configuration, the two microcontrollers can interface through a standard four pin Serial Peripheral Interface (�SPI�) bus 204 with a specific protocol. SPI is an interface used by Motorola's microcontroller to allow several SPI microcomputers, or SPI-type peripherals to be interconnected. The SPI bus 204 includes a separate line for data transmission and a separate line for the clock. The SPI system is particularly attractive for the channel mapping function because the system is designed to operate with one master-microcontroller controlling one or more slaves. Ideally, the microcontroller 202, the channel mapping microcontroller 200, and other peripheral devices can be configured as a single-master-multi-slave system, in which the channel mapping microcontroller 200 is one of the slave devices. A detailed specification of the SPI bus is disclosed in the �MC68HC05/705CCV�Product Specification� from Motorola and is expressly incorporated herein by reference as though set forth in full.
Preferably, a remote control unit 220 is provided for user control of the system. The remote control unit 220 has an infrared (�IR�) transmitter which emits a wide band IR signal to an IR detector (not shown) on the main microcontroller 202 in response to a user command. The remote control unit 220 allows the user to select the channel mapping function by merely depressing a key on the unit. The channel mapping select signal is transmitted to the main microcontroller 202 through the IR interface and initiates the channel mapping program stored in internal memory. The channel mapping program is best understood with reference to the flow diagrams of FIGS. 17-19. Turning to FIG. 17, once the channel mapping SELECTION 300 is made by the viewer, the main microprocessor will cause the television monitor to prompt the viewer to ENTER the ZIPCODE 302. Once the zipcode is successfully transmitted to the main microcontroller through the IR interface, the main microcontroller will enter into a television transmission SOURCE DETECTION 304 routine. If the main microcontroller determines that the television transmission source is a CABLE BOX SIGNAL 306, a set of IR codes stored in the main microcontroller is transmitted to an IR detector (not shown) in the cable box through an RF blaster (not shown) to SET the IR CODES 308 which are compatible with the cable box in use by means known in the art. This step is necessary to give the main microcontroller control over the tuner in the cable box so that the RF spectrum can be swept to locate channel mapping information. Once the proper IR codes are loaded into the cable box, or alternatively, if the main microcontroller determines that the television transmission is an OTA broadcast or a cable ready signal, then the main microcontroller enters into a CHANNEL MAP DOWNLOAD routine 310. Once the channel map is downloaded, the main microcontroller surrenders control of the tuner to the viewer.
