The present invention relates generally to PC docking stations for TVs.
The venerable “rabbit ears” TV antennas have become a rarity on the modern TV, which instead typically receives cable TV signals and/or satellite TV signals and/or recorded content from sources such as, e.g., digital video recorders (DVR) and digital video disk (DVD) players through a receiver broadly referred to as a “set top box” (STB). A type of STB is the so-called “set back box” (SBB) which differs from a STB chiefly by being controlled by the same remote control that controls the TV.
With the advent of high resolution digital TVs such as high definition TVs (HDTVs), to extend communication protocols to digital multimedia that includes audio for the purpose of, e.g., playing digital movies and the like, a protocol referred to as High Definition Multimedia Interface (HDMI) has been developed. HDMI is similar to Digital Visual Interface (DVI), a protocol developed primarily for computers that consequently does not envision processing audio data, except that HDMI envisions the use of audio as well as video data and it adds television-related resolutions. Both DVI and HDMI are intended for wired transmission, and HDMI further permits the encryption of digital multimedia using an encryption method known as High-Bandwidth Digital Content Protection (HDCP), which may also be used with DVI. An advantageous feature of HDMI is that it supports consumer electronics control (CEC), which permits control of the source (SB/DVD player/DVR etc.) and the TV using a single remote control.
A dock for a PC to interface with a TV is provided so that the TV has access via the dock to resources within the PC and the likewise the PC has access to resources within the TV. For example, the TV can access in the PC hard disk storage, optical disk storage, an Internet interface, network services, flash drive ports, video camera, microphone, data entry devices. The PC can access within the TV a digital TV tuner (ATSC, QAM, etc.), an Internet interface, network services. Furthermore, processing power can be shared between the PC and TV, i.e., command processing can be apportioned between the PC and TV, e.g., the greater processing power of the PC processor may be used by the TV processor, whereas the dedicated hardware accelerated resources of the TV may be used by the PC processor.
The dock may be generic in that it can accept any portable computer using standard interfaces such as HDMI, USB, etc. Or, the dock can be a “smart dock: in that the dock operably couples the computer to the TV only if the computer and TV have prior knowledge of each other's connectability features, e.g., so that graphics commands generated in the computer are executed by a graphics processor in the TV for display of the graphics on the TV.
Accordingly, a system includes TV including a TV display and a TV processor, and a computer dock communicating with the TV processor and configured to engage a portable computer. The computer dock includes at least one user-manipulable input device generating input signals to the TV processor to navigate a user interface (UI) presented on the TV display.
The dock may be integrated in the chassis of the TV or may be separate therefrom. In example embodiments the dock communicates with the TV using a control link such as a universal serial bus (USB) link and/or an Ethernet link, and may also communicate with the TV using a high definition multimedia interface (HDMI) link.
In example implementations, a first user-generated selection signal can cause input signals from the input device of the dock to be sent to a computer disposed in a bay of the dock, while a second selection signal may cause input signals from the input device of the dock to be sent to the TV. The dock can relay signals from the TV generated by a TV remote control (RC) to a computer engaged with the dock. “Relay” can refer to no processing in the dock, but transferring signals only; or processing is split between the TV and PC; or the TV processes all commands with the PC simply providing content streams.
In another aspect, a computer dock for a TV defines a surface configured to engage a computer. The dock has at least one input device, a HDMI port configured to communicate with a TV, and a USB and/or Ethernet port configured to communicate with the TV.
In another aspect, a portable computer has a portable housing, a processor in the housing, and a computer monitor on the housing communicating with the processor. The computer also includes at least one computer input device on the housing. When the processor determines that the computer is engaged with a dock, the processor causes a user interface to be presented (on, e.g., the monitor or on a TV display associated with a TV communicating with the dock) and navigated by a user to determine whether input signals from the dock are provided as input to the TV or as input to the computer. The user interface can present, e.g., resources in the PC that are available to the TV as discussed above.
The details of the present invention, both as to its structure and operation, can best be understood in reference to the accompanying drawings, in which like reference numerals refer to like parts, and in which:
Referring initially to
As shown in
An optical disk player 38 may also communicate with the TV processor 14 using HDMI as well as a universal serial bus (USB) link for control. Furthermore, a personal computer 40 can communicate with the TV processor. In the embodiment shown in
In the embodiment shown in
Accordingly, for a fuller understanding of the PC dock and referring to the details of
The PC 40 may be, without limitation, a laptop computer or notebook computer which may include a wired or wireless network transceiver 48 controlled by a PC processor 50 accessing instructions on a computer readable medium 52. The transceiver 48 is configured to communicate with the Internet. The PC 40 also typically has a relatively small display 54 that is smaller than the TV display 16. Also, the computer 40 typically has a keyboard or keypad 56 and point and click device 57.
The dock 42 may include a wired or wireless keypad 58 that in some example embodiments may be provided on the dock 42 itself or near the dock 42 and connected thereto by a wired or wireless link. In some embodiments the dock 42 may further include a wired or wireless pointing and clicking device 59 such as a mouse or joystick. In some implementations the dock keyboard or keypad 58 is a conventional QWERTY arrangement although other arrangements can be made. In any case, the dock 42 may include a dock processor 60 accessing instructions on a computer readable medium 62. The dock 42 may also include a wired or wireless network transceiver 64 configured to communicate with the Internet.
In other implementations the PC 40 may not mechanically engage the dock 42, but instead maybe placed near the dock 42 and may communicate therewith through a wired or wireless link such as a USB link, a Bluetooth link, a 60 GHz wireless link, or other link.
When the PC 40 is engaged with the dock 41 or 42 as intended in the examples shown, output from the PC processor 50 is presented through the dock 42 on the TV display 16, while input to the PC processor 50 may be made through the dock keyboard or keypad 58 and/or pointing and clicking device 59. Or, input to the PC may be effected using the RC 24 as more fully described below. In either case, the dock processor 60, when provided, can cooperate with the PC processor 50 and as mentioned above may communicate therewith through a wired or wireless link or through direct contact between exposed connectors on the phone and dock.
As mentioned above, the dock 41/42 can communicate with the TV using a HDMI link over which multimedia data from, e.g., an optical disk player 66 in the PC 40 may be conveyed for display on the TV, as well as a USB link, over which control signals between the TV processor and the PC processor may be conveyed. Accordingly, since, as understood herein, the USB protocol is not bipolar, a USB port 70 of the dock 42 may be a device USB link, with the dock 42 also potentially including a host USB port 72 if desired, with USB device ports not being the same as USB host ports. The TV's USB port receiving the USB link may be a USB host port, however. Likewise, the PC 40 can communicate with the dock 42 over a HDMI link as well as a USB and/or network (e.g., Ethernet) link (established by wired or wireless connections, contacts within the dock 42 that mate with corresponding contacts on the PC, or otherwise). The PC 40 may also have a device USB port as well as a host USB port.
Once the PC 40 is connected via HDMI and USB/Ethernet to the TV processor 14 through the dock 42 as indicated by, e.g., the above-mentioned dock signal, the TV processor 14 may configure the display 18 to present a cross media bar (XMB) user interface listing available sources of multimedia input for display. As shown in
Now referring to
If the PC is selected at decision diamond 82, the signals generated by the dock input devices are used to control the PC at block 84. On the other hand, if the TV is selected at decision diamond 82, the signals generated by the dock input devices are used to control the TV at block 86. In this way, in addition to or in lieu of using the RC 24 to input commands to the TV, a user may manipulate the dock input devices to, e.g., navigate around various TV UIs such as the XMB shown in
Additionally, as shown in
In variations, the dock input devices can be manipulated to effect the above selections and commands in lieu of the RC 24. Thus, for example, a user may use the arrow keys of the dock keyboard 58 or a user may use the dock mouse 59 to select an input source from the XMB. In some variations, the PC processor 42 may execute conventional PC tasks such as, for example, word processing, in which case the PC processor 42 uses the TV display 18 as an output device to, e.g., present over the HDMI link or USB link the text of a document being executed by the PC processor 42 using a word processing application.
In some embodiments, when content from the PC is presented on the TV, the PC may decode the content, send the content over the HDMI link and send associated user interface information over the control link to the TV. If no HDMI link is provided from the PC to the TV through the dock, and only, e.g., a USB link is provided, the PC may encrypt the content and then send it to the TV for decryption, decoding, and rendering.
In some embodiments, referring back to
It may now be appreciated that owing to the above-described communication links and coupling of the PC to the TV through the dock, when the TV has no network interface 28 the network connectivity of the dock and/or PC can be extended to the TV. Likewise, when the TV has a network interface 28 the network connectivity of the TV can be extended to the PC (if the PC has no network connection) through the dock across the control link.
While the particular PC DOCK FOR TV is herein shown and described in detail, it is to be understood that the subject matter which is encompassed by the present invention is limited only by the claims.
