Description

METHOD AND APPARATUS FOR COMMUNICATING FROM HEADEND TO

REMOTE CONTROL DEVICE

CROSS-REFERENCE TO RELATED APPLICATIONS

This application is related to the non-provisional application, Attorney Docket No. PU120135, entitled "Pseudo-Interactive Program Guide Over A Local Network", which is commonly assigned, incorporated by reference herein, and currently filed herewith.

TECHNICAL FIELD

The present principles relate generally to electronic program guides and, more particularly, to a pseudo-interactive program guide provided from a head-end or gateway device over a local network (e.g., a local terrestrial or cable distribution network) to a receiving device and communication with a remote control device.

BACKGROUND

This section is intended to introduce the reader to various aspects of art, which may be related to the present embodiments that are described below. This discussion is believed to be helpful in providing the reader with background information to facilitate a better understanding of the various aspects of the present disclosure. Accordingly, it should be understood that these statements are to be read in this light.

Individual in-room receivers (e.g., televisions, dedicated receivers, and so forth) cannot generate a guide. A headend device can receive program guide information from content or service providers and/or generate a guide and send the guide out over the distribution network to end user devices.

Headends exist that output a program guide implemented as a scrolling non- interactive display, broadcast over a single quadrature amplitude modulation (QAM) channel. Thus, the user at the receiver end cannot interact with the guide.

Moreover, in the aforementioned prior art headends, no backchannel exists to facilitate communication from the in-room receiver to the distribution headend. Rather, only front-channel communication from the headend to the receiver exists. LodgeNet™, a media provider specifically directed to hospitality and healthcare businesses, provides an interactive guide. However, the guide is dependent on a backchannel line of communication from the receivers to the headend. The LodgeNet™ hospitality system uses a building local area network (B- LAN) to facilitate two way communication. Two way communication capability, including communication to the end user device, is much harder to design and install than one way communication capability.

Similar problems may exist in a home media distribution system. The ability to provide a backchannel line of communication from the various receivers distributed in the home to a home gateway device acting as a headend may be limited by the distribution system.

Further, the user experience for television media content viewing is enhanced through the use of a program guide that is interactive in response to a user input. Systems that lack complete two way communication may limit the user experience. Therefore, there is a need for a program guide delivery mechanism over a local network that improves the user experience by providing a level of interactivity in response to user inputs. Additionally, there is a need for a mechanism to conveniently and easily provide information related to program operation to end user devices.

SUMMARY

These and other drawbacks and disadvantages of the prior art are addressed by the present principles, which are directed to a dongle for communications from a headend to a remote control device.

According to an aspect of the present principles, there is provided a method.

The method includes receiving a data stream. The data stream includes a plurality of video programs and a set of packets used for identifying program channels including a portion of a program guide. The data stream is received on a wired communication medium and provided to at least one video display device. The method further includes identifying the set of packets used for identifying the program channels including the portion of the program guide. The method also includes transmitting the set of packets to a remote control device using a wireless communication medium. The remote control device is used to control the at least one video display device. According to another aspect of the present principles, an apparatus is described that includes a receiver that receives a data stream, the data stream including a plurality of video programs and a set of packets used for identifying program channels including a portion of a program guide, the data stream received on a wired communication medium and provided to at least one video display device, a program guide information identifier coupled to the receiver, the program guide information identifier identifying the set of packets used for identifying the program channels including the portion of the program guide, and a transmitter coupled to the program guide information identifier, the transmitter transmitting the set of packets to a remote control device using a wireless communication medium, the remote control device used to control the at least one video display device.

These and other aspects, features and advantages of the present principles will become apparent from the following detailed description of exemplary embodiments, which is to be read in connection with the accompanying drawings.

DETAILED DESCRIPTION

The present principles are directed to a method and apparatus for communication from a headend to a remote control device. A device facilitates communication between a centrally located system headend and a remote control device located in a room.

In an embodiment, information from the headend (including, but not limited to, guide information, channel mappings, tuning commands, and so forth) is broadcast over a radio frequency (RF) cable network. In an embodiment, the device receives that information from the RF cable network via RF input and relays the information to the remote control device via zigbee radio frequency for consumer electronics (RF4CE) pairing. Of course, the present principles are not limited to using a RF4CE pairing and, thus, other wireless communication protocols and/or standards can be used in accordance with the teachings of the present principles, while maintaining the spirit of the present principles.

A pseudo-interactive program guide may be delivered from the headend to each room, for example, in a home or other location. The program guide includes image stills representative of portions of the program guide mapped across QAM sub-channels. The remote control device in each room may store the mapping, and, depending on user key presses, may directly tune to one of the sub-channels contains the pseudo-interactive program guide image stills to create the perception of an interactive program guide for the user. A device is connected to the network, often referred to as a dongle, that allows communication from the headend to the remote control device. In this way, the remote control device can obtain the mapping of program guide image stills from the headend.

Thus, in an embodiment, the present principles provide a separate forward communication interface to one or more remote control devices used to control televisions in a multi-channel multi-room display network. In this embodiment, the forward communication interface enables the communication of the mapping information for displaying a pseudo-interactive guide on the televisions. A pseudo- interactive guide includes a set of still images transmitted from a headend to a television that is accessible through a standard user interface. The configuration provides the look and feel of a conventional interactive guide without providing bidirectional communications. The present principles identify the mapping/management information that is sent along with the conventional video (e.g., a QAM cable signal), and streams and re-transmits this information through a wireless interface (e.g., RF4CE) to one or more remote control devices. The remote control devices maintain the mapping for use in conjunction with the user controls for selecting the appropriate channels including the guide information.

Initially, a system for delivering various types of content to a user will be described.

FIG. 1 shows an exemplary system 100 for delivering content to a location (e.g., a home or business) or end user, in accordance with an embodiment of the present principles. The content originates from a content source 102, such as a movie studio or production house. The content may be supplied in at least one of two forms. One form may be a broadcast form of content. The broadcast content is provided to the broadcast affiliate manager 104, which is typically a national broadcast service, such as the American Broadcasting Company (ABC), National Broadcasting Company (NBC), Columbia Broadcasting System (CBS), etc. The broadcast affiliate manager 104 may collect and store the content, and may schedule delivery of the content over a delivery network, shown as delivery network 1 (106). Broadcast affiliate manager 104 may also deliver program information for current and future programs, in the form of a program guide, over the delivery network. Delivery network 1 (106) may include satellite link transmission from a national center to one or more regional or local centers. Delivery network 1 (106) may also include local content delivery using local delivery systems such as over the air broadcast, satellite broadcast, or cable broadcast. The locally delivered content is provided to a user's set top box/digital video recorder (DVR) 108 in a user's home, where the content will form part of the results of subsequent searches by the user.

A second form of content is referred to as special content. Special content may include content that may have been delivered as premium viewing, pay-per- view, or other content otherwise not provided to the broadcast affiliate manager. In many cases, the special content may be content requested by the user. The special content may be delivered to a content manager 1 10. The content manager 1 10 may be a service provider, such as an Internet website, affiliated, for instance, with a content provider, broadcast service, or delivery network service. The content manager 1 10 may also incorporate Internet content into the delivery system, or explicitly into the search only such that content may be searched that has not yet been delivered to the user's set top box/digital video recorder 108. The content manager 1 10 may deliver the content to the user's set top box/digital video recorder 108 over a separate delivery network, delivery network 2 (1 12). The content manager 1 10 may also deliver additional program information for current and future programs, for instance in some form of a program guide, to the user over the delivery network. Delivery network 2 (1 12) may include high-speed broadband Internet type communications systems. It is important to note that the content from the broadcast affiliate manager 104 may also be delivered using all or parts of delivery network 2 (1 12) and content from the content manager 1 10 may be delivered using all or parts of Delivery network 1 (106). In addition, the user may also obtain content directly from the Internet via delivery network 2 (1 12) without necessarily having the content managed by the content manager 1 10.

The set top box/digital video recorder 108 may receive different types of content from one or both of delivery network 1 and delivery network 2. The set top box/digital video recorder 108 processes the content, and provides a separation of the content based on user preferences and commands. The set top box/digital video recorder may also include a storage device, such as a hard drive or optical disk drive, for recording and playing back audio and video content. Further details of the operation of the set top box/digital video recorder 108 and features associated with playing back stored content will be described below in relation to FIG. 2. The processed content is provided to a display device 1 14. The display device 1 14 may be a conventional 2-D type display or may alternatively be an advanced 3-D display. It should be appreciated that other devices having display capabilities such as wireless phones, PDAs, computers, gaming platforms, remote controls, multi-media players, or the like, may employ the teachings of the present disclosure and are considered within the scope of the present disclosure.

It is important to note that more than one set-top box/digital video recorder 108 may be included at a location (e.g., a home or business). Further, one or more of a set-top box/digital video recorder 108 may serve as a gateway or head-end device to other devices in the location. Operation as a gateway or head-end device includes receiving and redistributing the content (e.g., audio and video content and/or program guide information) to the other devices. These devices may include, but are not limited to set-top boxes, thin client devices, display devices, computers, tablets, and the like.

FIG.2 shows an exemplary core of a set top box/digital video recorder 200, in accordance with an embodiment of the present principles. The device 200 shown may also be incorporated into other systems including the display device 1 14 itself. In either case, several components necessary for complete operation of the system are not shown in the interest of conciseness, as they are well known to those skilled in the art.

In the device 200 shown in FIG. 2, the content is received in an input signal receiver 202. The input signal receiver 202 may be one of several known receiver circuits used for receiving, demodulation, and decoding signals provided over one of the several possible networks including over the air, cable, satellite, Ethernet, fiber and phone line networks. The desired input signal may be selected and retrieved in the input signal receiver 202 based on user input provided through a control interface (not shown). It is to be appreciated that the input signal receiver 202 may in certain embodiments be a transceiver for two way communication to and from the set top box/digital video recorder 108. In certain embodiments, the transceiver will output information, e.g., a search request to delivery network 2 (1 12) to search for Internet content.

The decoded output signal from the input signal receiver 202 is provided to an input stream processor 204. The input stream processor 204 performs the final signal selection and processing, and includes separation of video content from audio content for the content stream. The audio content is provided to an audio processor 206 for conversion from the received format, such as compressed digital signal, to an analog waveform signal. The analog waveform signal is provided to an audio interface 208 and further to the display device 1 14 or an audio amplifier (not shown). Alternatively, the audio interface 208 may provide a digital signal to an audio output device or display device using an HDMI (High-Definition Multimedia Interface) cable or alternate audio interface such as via a SPDIF (Sony/Philips Digital Interconnect Format). The audio processor 206 also performs any necessary conversion for the storage of the audio signals.

The video output from the input stream processor 204 is provided to a video processor 210. The video signal may be one of several formats. The video processor 210 provides, as necessary a conversion of the video content, based on the input signal format. The video processor 210 also performs any necessary conversion for the storage of the video signals.

A storage device 212 stores audio and video content received at the input. The storage device 212 allows later retrieval and playback of the content under the control of a controller 214 and also based on commands, e.g., navigation instructions such as fast-forward (FF) and rewind (Rew), received from a user interface 216. The storage device 212 may be a hard disk drive, one or more large capacity integrated electronic memories, such as static random access memory, or dynamic random access memory, or may be an interchangeable optical disk storage system such as a compact disk drive or digital video disk drive.

The converted video signal, from the video processor 210, either originating from the input or from the storage device 212, is provided to the display interface 218. The display interface 218 further provides the display signal to a display device of the type described above. The display interface 218 may be an analog signal interface such as red-green-blue (RGB) or may be a digital interface such as high definition multimedia interface (HDMI). It is to be appreciated that the display interface 218 will generate the various screens for presenting the search results in a three dimensional array as will be described in more detail below.

The controller 214 is interconnected via a bus to several of the components of the device 200, including the input stream processor 202, audio processor 206, video processor 210, storage device 212, and a user interface 216. The controller 214 manages the conversion process for converting the input stream signal into a signal for storage on the storage device or for display. The controller 214 also manages the retrieval and playback of stored content. Furthermore, the controller 214 performs searching of content, either stored or to be delivered via the delivery networks described above. The controller 214 is further coupled to control memory 220 (e.g., volatile or non-volatile memory, including random access memory, static RAM, dynamic RAM, read only memory, programmable ROM, flash memory, EPROM, EEPROM, etc.) for storing information and instruction code for controller 214. Further, the implementation of the memory may include several possible embodiments, such as a single memory device or, alternatively, more than one memory circuit connected together to form a shared or common memory. Still further, the memory may be included with other circuitry, such as portions of bus communications circuitry, in a larger circuit.

To operate effectively, the user interface 216 of the present disclosure employs an input device. In one embodiment, the input device is a remote controller, with a form of motion detection, such as a gyroscope or accelerometer, which allows the user to move a cursor freely about a screen or display. In another embodiment, the input device is a controller in the form of a touch pad or touch screen remote that takes movements on the user's finger and translates this to the position of a cursor on the screen, or alternatively be used to provide a virtual keyboard. In other embodiments, the controller may include a full keyboard for typing search entries and also may include an accelerometer/gyroscope to track the user's movement to allow selection of elements to act as keys for a search. Other types of input devices such as conventional remotes, wireless devices such as phones and PDAs, motion capture devices or the like are also considered within the scope of the present disclosure.

FIG. 3 shows an exemplary processing system 300 to which the present principles may be applied, in accordance with an embodiment of the present principles. The processing system 300 includes at least one processor (CPU) 302 operatively coupled to other components via a system bus 304. A memory cache 306, read only memory (ROM) 308, random access memory (RAM) 310, display adapter 360, an input/output (I/O) adapter 312, a user interface adapter 314, and a network adapter 398, are operatively coupled to the system bus 304. Processing system may be used as part of a gateway or head-end device used in a multi-client, multi-user, or multiple dwelling unit system. A display device 316 is operatively coupled to system bus 304 by display adapter 360. Similarly, a speaker 332 is operatively coupled to system bus 304 by sound adaptor 330. A first storage device 318 and second storage device 324 (e.g., a magnetic or optical disk storage device) are operatively coupled to system bus 304 by I/O adapter 312.

A first user input device 352 (e.g., a mouse) and a second user input device 354 (e.g., a keyboard) are operatively coupled to system bus 304 by user interface adapter 314. A third user input interface 356 (e.g., an infra-red (IR) receiver) is also operatively coupled to system but 304. The first user input device 352, second user input device 354, and third user input interface 356 are used to input and output information to and from system 300.

A transceiver 396 is operatively coupled to system bus 304 by network adapter 398.

Of course, the processing system 300 may also include other elements (not shown), as readily contemplated by one of skill in the art, as well as omit certain elements. For example, various other input devices and/or output devices, including, but not limited to, various types of wireless and/or wired input and/or output devices, can be included in processing system 300, depending upon the particular implementation of the same, as readily understood by one of ordinary skill in the art. Moreover, additional processors, controllers, memories, and so forth, in various configurations can also be utilized as readily appreciated by one of ordinary skill in the art. These and other variations of the processing system 300 are readily contemplated by one of ordinary skill in the art given the teachings of the present principles provided herein.

In one embodiment, transceiver 396 may include, or be replaced by, a broadcast modulator device. The broadcast modulator device may be capable of modulating and transmitting signals as broadcast channels in a QAM signal format. Each channel may include one or more subchannels, each capable of carrying a video program stream. CPU 302 may be capable of rendering a plurality of views of a program guide, including a first view and a second view. The program guide may be received from a satellite or other broadcast content service provider (e.g., broadcast affiliate manager 104 or content manager 1 10 described in FIG. 1 ). The program guide information may be stored in RAM 310 and processed to generate a program stream containing a still image or picture depicting a portion of the program guide. More particularly, each still image or picture corresponds to (i.e., is representative of) a respective content on a respective subset of content channels from among a set of content channels available for reception. CPU 302 further performs a mapping between a respective picture (e.g., from among a set of pictures) and a respective quadrature amplitude modulation (QAM) sub-channel (e.g., from among a set of QAM sub-channels) to generate a map. The Broadcast modulator, as part of transceiver 396, transmits the map along with the still images or pictures of the portions of the program guide as subchannels in broadcast signal to another receiving device connected to the processing system 300. Further details regarding the generation and delivery of the program guide images will be described below.

It is to be appreciated that set-top box 200 described above with respect to FIG. 2 is a set-top box 200 for implementing respective embodiments of the present principles. Part or all of processing system 300 may be implemented in one or more of the elements of set-top box 200 or other device.

Moreover, it is to be appreciated that system 400 described below with respect to FIG. 4 is a system for implementing respective embodiments of the present principles. Part or all of processing system 300 may be implemented in one or more of the elements of system 400.

FIG. 4 shows an exemplary system 400 for providing a pseudo-interactive guide over quadrature amplitude modulation, in accordance with an embodiment of the present principles. The system 400 includes a headend 410 and a receiving device 450. The headend 410 and the receiving device 450 are interconnected via a network 499.

The headend 410 includes a mapper 41 1 , a view rendering processor 420, and a transmitter 430.

The mapper 41 1 maps a respective picture (e.g., from among a set of pictures) to a respective quadrature amplitude modulation (QAM) sub-channel (e.g., from among a set of QAM sub-channels) to generate a map. Each picture corresponds to a respective content on a respective subset of content channels from among the set of content channels available for reception.

The view rendering processor 420 renders or generates a view of a program guide and at least another view of the program guide. The transmitter 430 transmits the view of the program guide on a quadrature amplitude modulation sub-channel. The transmitter 430 also transmits the other view of the program guide on a different quadrature amplitude modulation subchannel. The view and the other view are transmitted over a front-channel from the headend to a receiver connected to the headend.

In an embodiment, the view includes a picture representative of content on a subset of content channels from among a set of content channels available for reception. In an embodiment, the other or second view includes a different picture representative of a different content on a different subset of content channels from among the set of content channels available for reception.

While the view and the other or second view, as well as other information, are described herein as being transmitted to a receiver connected to the headend, of course other devices can be used in place of the headend or receiver for this and some of the following steps described herein with respect to FIGs. 4-6, as readily appreciated by one of ordinary skill in the art.

The transmitter 430 additionally transmits the map to the receiver, using the front-channel. The transmitter 430 also transmits, to the receiver using the front- channel, any changes to the map.

The transmitter 430 further transmits an instruction to the receiver to recognize the view and the other view based on channel identifiers associated with the view and the other view. This helps the receiver determine how the view and the other view are to be recognized, e.g., from among a set of possible determination methods.

The receiving device 450 includes a receiver 460 and a control interface 470. The receiver 460 receives a view of a program guide on a quadrature amplitude modulation sub-channel. The view includes a picture representative of content on a subset of content channels from among a set of content channels available for reception

The receiver 460 also receives another, or a second, view of the program guide on a different quadrature amplitude modulation sub-channel responsive to a user request. The other view includes a different picture representative of a different content on a different subset of content channels from among the set of content channels available for reception. The control interface 470 allows a user to provide navigation inputs, selections inputs, and so forth, in order to see various views of the program guide.

In operation, receiving device may receive a map corresponding to a mapping a respective picture, view, or still image (e.g., from among a set of pictures, views, or still images) and a respective quadrature amplitude modulation (QAM) sub-channel (e.g., from among a set of QAM sub-channels). Each picture, view, or still image corresponds to (that is, is representative of) a respective content on a respective subset of content channels from among a set of content channels available for reception as normally provided as part of a program guide. One or more views of the program guide may be received on a quadrature amplitude modulation subchannel from the headend responsive to a user request. Each of the views is a content stream of separate pictures representative of content on a subset of content channels from among a set of content channels available for reception.

The map and any changes to the map along with the one or more views are received from the headend by the receiving device 450 using a front-channel established from the headend to the receiver.

It is important to note that every static image or picture of the portion of the program guide may be rendered or generated in the headend. The headend distributes each program guide still or picture on a separate QAM sub-channel to reach the receivers. Further, the headend may generate and transmit the QAM subchannels on an as needed basis based on user input.

It is also important to note that system 400 may include a mechanism for communicating the map information to an intermediate communication device (not shown) that is interfaced to receiving device 450 or to a display device (not shown), such as display device 1 14 shown in FIG. 1 . In one embodiment, the intermediate communication device is a dongle device that identifies and extract the map information from the wired communication network (e.g, the QAM channel) and provides the map information to receiving device 450 or to a display device over a separate wireless communication network (e.g., RF4CE). Further details related to the intermediate communication device (e.g., dongle device) will be described below.

It is to be appreciated that processing system 300 may perform at least part of the methods described herein including, for example, at least part of method 500 of FIG. 5 and/or at least part of method 600 of FIG. 6. Similarly, part or all of system 400 may be used to perform at least part of method 500 and/or at least part of method 600. Also, part or all of set-top box 200 may be used to perform at least part of method 500 and/or at least part of method 600.

FIG. 5 shows an exemplary method 500 for providing a pseudo-interactive program guide over a broadcast channel on a local network, in accordance with an embodiment of the present principles. Method 500 may be used in conjunction with system 100 described in FIG. 1 as well as processing system 300 described in FIG. 3. Method 500 is more specifically described with respect to the operation of system 400 and more particularly to headend 410 described in FIG. 4.

At step 510, a plurality of views of a program guide are rendered or generated. The plurality of views includes a view (e.g., a first view) and another view (e.g., a second view) each depicting a different portion of the program guide. The plurality of views are generated by encoding each view into a program channel or subchannel using video encoding techniques (e.g., Moving Picture Experts Group (MPEG) standard MPEG-2 or MPEG-4).

At step 520, a mapping is performed between a respective view (e.g., from among the plurality of views, pictures, or still images) and a respective quadrature amplitude modulation (QAM) channel or sub-channel (e.g., from among a set of QAM sub-channels) to generate a map. Each view corresponds to (i.e., is representative of) a respective content on a respective subset of content channels from among a set of content channels available for reception as provided as part of a program guide.

At step 530, the map is transmitted to a receiver connected to the headend using a front-channel from the headend to a receiver connected to the headend.

At step 540, the view (e.g., a first view) of the program guide is transmitted to the receiver on a quadrature amplitude modulation sub-channel. The view includes a picture representative of content on a subset of content channels from among the set of content channels available for reception.

At step 550, the other view (e.g., a second view) of the program guide is transmitted to the receiver on a different quadrature amplitude modulation subchannel. The other view includes a different picture representative of a different content on a different subset of content channels from among the set of content channels available for reception.

At step 560, any changes to the map are transmitted to the receiver. The map, the view, the other view, and changes to the map are transmitted from the headend to the receiver using a front-channel established and broadcast from the headend (e.g., headend 410) to the receiver (e.g., receiver 450).

FIG. 6 shows another exemplary method 600 for receiving and processing a pseudo-interactive program guide over a broadcast channel, in accordance with an embodiment of the present principles. Method 600 may be used in conjunction with system 100 described in FIG. 1 as well as processing system 300 described in FIG. 3. Method 600 may also be used in device 200 described in FIG. 2. Method 600 is more specifically described with respect to the operation of system 400 and more particularly to receiver 450 described in FIG. 4

At step 610, a map is received from the headend. The map corresponds to a mapping performed between a respective picture, view, or still image (e.g., from among a set of pictures, views, or still images) and a respective quadrature amplitude modulation (QAM) sub-channel (e.g., from among a set of QAM sub- channels). Each picture, view, or still image corresponds to (that is, is representative of) a respective content on a respective subset of content channels from among a set of content channels available for reception as normally provided as part of a program guide.

At step 620, a view (e.g., a first view) of a program guide on a quadrature amplitude modulation sub-channel is received from the headend responsive to a user request. The view includes a picture representative of content on a subset of content channels from among a set of content channels available for reception

At step 630, another view (e.g., a second view) of the program guide on a different quadrature amplitude modulation sub-channel responsive to a user request is received from the headend. The other or second view includes a different picture representative of a different content on a different subset of content channels from among the set of content channels available for reception.

At step 640, any changes to the map are received from the headend.

The map, the view, the other second view, and changes to the map are received from the headend by the receiver using a front-channel established from the headend to the receiver.

In an embodiment, instead of generating an interactive guide interface within a receiver, every static image that is part of the guide is rendered or generated in the headend. The headend distributes each guide still (picture) on a separate QAM subchannel to reach the receivers.

The guide stills may be mapped across QAM sub-channels in a predetermined, fixed manner, or the headend can direct the receivers to recognize the guide stills with channel identifiers or management services commands. Once the mapping is determined, there is no need for a backchannel for the receiver to navigate the guide. Any changes to the guide data channel mapping can be communicated along the front-channel from the headend.

When a user of an in-room receiver presses the "Guide" key command, the receiver tunes to the QAM channel displaying the guide data corresponding to the currently tuned channel. While the receiver is displaying a guide data channel, navigation key presses tune to other QAM channels that include the corresponding guide data still images.

FIG. 7 shows an exemplary grouping of program guide images or stills 700 with interactive scrolling, in accordance with an embodiment of the present principles. In particular, FIG. 7 shows each guide still image including information from a group of channels mapped to and provided on a sub-channel (e.g., a QAM sub-channel). A user interface (e.g., user interface 216 shown in FIG. 2) responds to inputs from a user. Pressing the Guide key 701 while watching a current content channel will tune to the channel or sub-channel that includes that content channel's information along with information for other channels, such as channels adjacent to the current content channel. Using navigation keys 702 will tune to another channel or sub-channel that includes a different guide image to create the perception of scrolling for the user. In this manner, a user experience similar to a true interactive program guide may be provided to the user.

FIG. 8 shows a set of exemplary individual highlighted program guide images or stills 800 with interactive browsing, in accordance with an embodiment of the present principles. In the embodiment of FIG. 8, every content channel, generally indicated by the reference numeral 891 , has a corresponding guide channel/still image, generally indicated by the reference numeral 892. The guide channel will have its paired content channel highlighted on the guide as described in further detail herein below. A key 810 is provided to show the relationship between state indicators for the content channel, the guide channel with the highlighted content channel, and the navigation functions. The embodiment of FIG. 8 operates similarly to the embodiment of FIG. 7, and navigation keys 802 tune to different guide image channels to create the illusion of browsing. The implementation of FIG. 8 further enables direct tuning to, or selection of content (i.e., a content channel) using the pseudo-interactive guide. The highlighting feature allows the user to hit the Select key 803 while a certain content channel is highlighted, and the receiver will tune to the desired content channel. In FIG. 8, a remote control 850 is shown, that includes a Guide key 801 , the navigation keys 802, the Select key 803, a static guide channel (highlighted content channel) state indicator 805, and content channel state indicator 806. The static guide channel (highlighted content channel) state indicator 805 indicates the current highlighted content channel . The content channel state indicator 806 indicates the current content channel.

In further detail regarding the highlighting feature, the guide image is on a particular channel, indicated by the (top) number shown in the static guide channel (highlighted content channel) state indicator 805. On that guide image, the information for its corresponding content channel, indicated in parenthesis, is distinguished (highlighted). In this way, the user knows which channel they will be tuning to if they press the select key 803. Pressing the up/down keys from a guide channel creates the perception to the user of the highlighter moving from one information section to another. Moreover, a static guide channel with its corresponding content channel highlighted could also display specific programming information unique to that content channel. In other words, the view for the portion of the program guide that is transmitted may include a channel highlighted in the view and may be transmitted as a program stream on a sub-channel of the highlighted channel.

As examples of highlighting, the information can be highlighted using a bright colored box surrounding the information or a change in background color for that section of information. Of course, the present principles are not limited to the preceding highlighting approaches and, thus, other approaches for highlighting the aforementioned information can also be used in accordance with the teachings of the present principles, while maintaining the spirit of the present principles.

FIG. 9 shows an exemplary system 900 for providing a device for communication from a headend to a remote control device, in accordance with an embodiment of the present principles. The system 900 includes a headend 910, a dongle device 920, a television 930, and a remote control device 940. System 900 may include features and operate in a manner similar to that described for system 100 in FIG. 1 or system 400 described in FIG. 4.

Headend 910 may operate in a manner similar to set-top box/digital video recorder 108 described in FIG. 1 or Media Server 410 described in FIG. 4. The headend 910 may be, for example, but is not limited to, the Technicolor™ COM1000 headend system. In an embodiment, the headend 910 sends out audio/video programming over a network of QAM channels distributed, for example, through a building cable network. In an embodiment, the headend 910 can also send guide stills mapped across QAM sub-channels and management/mapping information over lower frequencies.

The dongle device 920 is connected in between the cable input to the television 930 and the cable headend 910. In an embodiment, the dongle device 920 receives management and mapping information from the headend 910 and then relays that information to the remote control device 940 via a wireless communication medium (e.g., using RF4CE pairing or some other wireless protocol or standard). The (audio/video) programming is all passed through to the television 930.

The dongle device 920 includes a receiver 921 , a program guide information identifier 922, and a transmitter 923.

The receiver 921 receives a data stream from the headend 910. The data stream includes video programs and a set of packets used for identifying program channels including a portion of a program guide. The data stream is received on a wired communication medium and provided to the television 930. While the embodiment of FIG. 9 shows a single television, the present principles are not limited to the same and can be readily employed in multi-television environments while maintaining the spirit of the present principles.

The program guide information identifier 922 identifies the set of packets used for identifying the program channels including the portion of the program guide.

The transmitter 923 transmits the set of packets to the remote control device 940 using a wireless communication medium. The remote control device 940 is used to control the television 930. While shown as separate elements in the embodiment of FIG. 9, the receiver 921 and the transmitter 923 can be embodied in a single device such as a transceiver, as readily appreciated by one of ordinary skill in the art. The television 930 displays the programs (e.g., a currently viewed program) and the pictures or image stills that form the pseudo-interactive program guide. Television 930 may operate in a manner similar to display device 1 14 described in FIG. 1 and may further include elements similar to those found in device 200 described in FIG. 2).

The remote control device 940 is used to select a current program to view and for navigation through the pseudo-interactive program guide as described herein. For a multi-room environment, there is a remote control device 940 in each room that is capable of storing channel and guide image still mapping information. The information is used to directly tune to the desired channel in response to a user key press and the current state of remote control device 940. The navigation features associated with using the pseudo-interactive program guide mechanism with remote control device 940 as described herein creates the appearance of an interactive guide to the user.

It is important to note that the dongle device 920 provides an intermediate connection between the headend 910 and the remote control device 930 for controlling television 930. Television 930 may receive program content from headend device 910 but may not be able to directly recognize program information or provide a user experience due to the absence of back channel communication to the headend 910. In this manner, the dongle device operates as an intermediate interface device when a communication backchannel is not present between headend device 910 and television 930 or any other device connected to the headend 910.

It is to be appreciated that system 900 described above with respect to FIG. 9 is a system for implementing respective embodiments of the present principles. Part or all of processing system 300 may be implemented in one or more of the elements of system 900. Moreover, part or all of system 900 may be used to perform at least part of method 500 and/or at least part of method 600 and/or at least part of method 1000 described below.

FIG. 10 shows an exemplary method 1000 for providing communication from a headend to a remote control device, in accordance with an embodiment of the present principles. In particular, the method 1000 may be performed by a device coupled between a headend or gateway device and an end user device (e.g., dongle 920). The device is intermediately connected with respect to a headend (e.g., headend 910) and a remote control device (e.g., remote control device 940). The method 1000 is performed in an absence of using a backchannel to communicate between the headend 910 and the remote control device 940 or other end user device (e.g., television 930). Although, method 1000 is primarily described with respect to system 900 described in FIG. 9, all or portions of method 1000 may be used with system 100 described in FIG.1 or system 400 described in FIG. 4.

At step 1010, a data stream is received at the device (e.g., dongle device 920). The data stream includes video programs and a set of packets used for identifying program channels including a portion of a program guide. The data stream is received on a wired communication medium from a headend or gateway device (e.g., headend 910) and provided to at least one video display device (e.g., television 930).

At step 1020, a set of packets in the received data stream that are used for identifying the program channels including the portion of the program guide is identified. In an embodiment, the set of packets include a map generated by mapping a respective picture (from a set of pictures) to a respective quadrature amplitude modulation (QAM) sub-channel (from a set of QAM sub-channels). Each picture in the set corresponds to a respective content on a respective subset of the program channels. Also, at step 1020, the packets are separated or isolated from the remaining portion of the received data stream.

At step 1030, the set of packets are transmitted to a remote control device using a wireless communication medium (e.g. RF4CE). The remote control device is used to control the at least one video display device.

At step 1040, one or more other packets used for identifying program channels including a portion of a program guide are received at the device (e.g., dongle device 920). The one or more other packets are transmitted from the headend or gateway (e.g., headend 910) via the wired communication medium and may be included as part of a data stream. In an embodiment, the one or more other packets specify changes to the map.

At step 1050, the one or more other packets are transmitted to the remote control device using the wireless communication medium (e.g., RF4CE).
