As shown in
The television 12 may be an analog television such as one conforming to the NTSC standard, a digital television such as one conforming to the ATSC digital television standard, or other television that is suitably equipped to receive the electrical lines 14. The electrical lines 14 may include any number and type of electrical lines dependent upon the types of equipment to be coupled through the remote jack pack 10 to the television 12.
The remote jack pack 10 supports a 3.5 mm audio input jack 16, left and right audio input jacks 18 and 20, a super VHS video input jack 22, a composite video input jack 24, and an RGB input jack 26. A radio audio input jack 28 is capable of accepting audio signals from a radio or other device. Because the radio audio input jack 28 may be supported on the back of the remote jack pack 10, it is shown in phantom.
The 3.5 mm audio input jack 16 is capable of receiving a corresponding plug from an MP3 player, CD, or radio. Accordingly, a user can play audio from any of these sources through the speakers of the television 12.
The left and right audio input jacks 18 and 20 are capable of receiving corresponding audio left and right plugs from audio equipment, a VCR, a DVD player, etc. Accordingly, a user can play the audio portion of a video cassette or DVD or the audio from audio equipment through the speakers of the television 12.
The super VHS video input jack 22 is capable of receiving video super VHS plugs from a super VHS player or DVD player. The audio from these devices can be plugged into one of the audio jacks described above. Accordingly, a user can play super VHS video and audio on the television 12.
The RGB input jack 26 is capable of receiving a plug from a computer or set top box so that a user can play the video of a game, a DVD, etc. from a user's computer on the television 12 or the video from a set top box on the television 12. The audio from the computer or set top box can be plugged into one of the audio jacks described above.
The composite video input jack 24 is capable of receiving video from a VCR or DVD. Accordingly, a user can play the video of a video cassette or DVD on the television 12.
The remote jack pack 10 may have other jacks such as a telephone jack 30, a high speed internet connection jack 32, and AC outlets 34 and 36. Accordingly, the user can connect a computer or other equipment to the telephone jack 30 and to the high speed internet connection jack 32 and can power various equipment such as a computer by way of the AC outlets 34 and 36. For these purposes, the remote jack pack 10 interconnects the telephone jack 30 with a telephone line 38, interconnects the high speed internet connection jack 32 with a high speed internet access line 40, and supplies AC power from AC lines 42 to the AC outlets 34 and 36.
The electrical lines 14 include three RGB lines 44, a composite video line 46, two (left and right) audio lines 48, and four control lines 50. The three RGB lines 44 connect the red (R), green (G), and blue (B) signals from the RGB input jack 26 to RGB inputs of the television 12. The composite video line 46 connects the composite video signal from the composite video input jack 24 to a video input of the television 12. As explained below, the composite video line 46 also connects the super VHS video input jack 22 to a video input of the television 12. The audio lines 48 connect the audio signals from the 3.5 mm audio input jack 16, from the left and right audio input jacks 18 and 20, and from the radio audio input jack 28 to audio inputs of the television 12. The control lines 50 connect various control signals from the remote jack pack 10 to the television 12, as explained below.
The remote jack pack 10 includes an audio portion 52 as shown in
The contacts of the switch 54 respond to the insertion of an audio plug into the 3.5 mm audio input jack 16 by opening so that the inserted audio plug is connected to the switch 56 and so that the left and right audio input jacks 18 and 20 are not connected to the switch 56. At the same time, the audio detector 58 detects that there is an audio signal on the 3.5 mm audio input jack 16 and, consequently, controls the switch 56 to couple this audio signal from the 3.5 mm audio input jack 16 to left and right audio output jacks 60 and 62 of the audio portion 52 of the remote jack pack 10. The left and right audio output jacks 60 and 62 connect to the audio lines 48.
Alternatively, when an audio plug is not inserted into the 3.5 mm audio input jack 16, the contacts of the switch 54 remain in their original positions. Accordingly, audio plugs inserted into the left and right audio input jacks 18 and 20 are connected to the switch 56 and the 3.5 mm audio input jack 16 is not connected to the switch 56. At the same time, the audio detector 58 detects that there is an audio signal on the left and right audio input jacks 18 and 20 and, consequently, controls the switch 56 to couple this audio signal from the left and right audio input jacks 18 and 20 to the left and right audio output jacks 60 and 62 and then on to the audio lines 48.
When a signal is present on the radio audio input jack 28, the audio detector 58 detects that there is an audio signal on the radio audio input jack 28 and, consequently, controls the switch 56 to couple this audio signal from the radio audio input jack 28 to the left and right audio output jacks 60 and 62 and then on to the audio lines 48.
The audio detector 58, such as a threshold comparator and a microprocessor, also supplies control signals, as explained more fully below, over appropriate ones of the control lines 50 to condition the television 12 to couple its appropriate audio sources to the audio processors of the television 12.
The audio detector 58 may be arranged to resolve the contention that is created when two or more plugs are inserted into the 3.5 mm audio input jack 16, the left and right audio input jacks 18 and 20, and/or the radio audio input jack 28 during overlapping periods of time. In this case, the audio detector 58 may be arranged or programmed to select one of the contending audio inputs for supply to the left and right audio output jacks 60 and 62. For this purpose, this audio input selection may be implemented according to any desired prioritization model.
The remote jack pack 10 further includes a video portion 64 as shown in
When a super VHS video plug is inserted into the super VHS video input jack 22, the combiner 70, such as a summing circuit, combines the luminance and chrominance signals of the super VHS signal into a composite video signal. The video detector 68 detects that there is a composite video signal at the output of the combiner 70 and, consequently, controls the switch 66 to couple this composite video signal from the combiner 70 to a composite video output jack 72 in the video portion 64 of the remote jack pack 10. The composite video output jack 72 connects to the composite video line 46.
When a composite video plug is inserted into the composite video input jack 24, the video detector 68 detects that there is a video signal on the composite video input jack 24 and, consequently, controls the switch 66 to couple this video signal from the composite video input jack 24 to the composite video output jack 72 and then on to the composite video line 46.
When an RGB plug is inserted into the RGB input jack 26, the resulting signal on the RGB input jack 26 is coupled directly through the remote jack pack 10 to an RGB output jack 74 and then on to the RGB lines 44.
The video detector 68, such as sync detector and a microprocessor, also supplies control signals, explained more fully below, over appropriate ones of the control lines 50 to condition the television 12 to couple its appropriate video sources to the video processors of the television 12. Assuming that the audio detector 58 and the video detector 68 have microprocessors as described above, the audio detector 58 and the video detector 68 may share the same microprocessor. These microprocessors or shared microprocessor may perform other functions, such as other switching functions, than those described herein.
The video detector 68 may be arranged to resolve the contention that is created when plugs are inserted into both the super VHS video input jack 22 and the composite video input jack 24 during overlapping periods of time. In this case, the video detector 68 may be arranged or programmed to select one of the contending video inputs for supply to the composite video output jack 72. For this purpose, this video input selection may be implement according to any desired prioritization model.
Thus, when the video detector 68 detects no signal on the super VHS video input jack 22, the RGB input jack 26, and the composite video input jack 24, it drives the control lines 0 and 1 high. In response to these control signals, the television 12 supplies the video output from its own tuner to its video processor for display to the user. A signal on control line 3 is not controlling as indicated by the x, and a signal on control line 2 controls audio as discussed below.
When the video detector 68 detects an RGB signal on the RGB input jack 26, it drives the control line 0 low and the control line 1 high. In response to these control signals, the television 12 supplies the RGB video on the RGB lines 44 to its video processor for display to the user. Again, a signal on control line 3 is not controlling as indicated by the x, and a signal on control line 2 controls audio as discussed below.
When the video detector 68 detects a composite video signal either on the composite video input jack 24 or at the output of the combiner 70, it drives the control line 0 high and the control line 1 low. In response to these control signals, the television 12 supplies the composite video on the composite video line 46 to its video processor for display to the user. Still again, a signal on control line 3 is not controlling as indicated by the x, and a signal on control line 2 controls audio as discussed below.
When the audio detector 58 detects no signal on the 3.5 mm audio input jack 16, the left and right audio input jacks 18 and 20, and the radio audio input jack 28, it drives the control line 3 high. In response to this control signal, the television 12 supplies the audio output from its own tuner to its audio processor for supply to its speakers. Any signal on control line 3 is not controlling, and signals on control lines 0 and 1 control video, as discussed above.
When the audio detector 58 detects an audio signal on the 3.5 mm audio input jack 16, the left and right audio input jacks 18 and 20, or the radio input jack 28, it drives the control line 0 low. In response to this control signal, the television 12 supplies the audio on the audio lines 48 to its audio processor for supply to its speakers. Again, any signal on control line 3 is not controlling, and signals on control lines 0 and 1 control video, as discussed above.
An exemplary television 80 is shown in
The exemplary television 80 also includes a television controller 92, a tuner 94, a video processor 96, an audio processor 98, a video display 100, and audio speakers 102. The television controller 92, for example, may comprise a microprocessor and controls the tuner 94 in accordance with a channel selected by a user.
When the television controller 92 detects x111 control signals on the control connector 90, the television controller 92 controls the video processor 96 and the audio processor 98 to process the video and audio from the tuner 94. When the television controller 92 detects x010 control signals on the control connector 90, the television controller 92 controls the video processor 96 to process the video from the RGB connector 86 and controls the audio processor 98 to process the audio from the audio connector 88. When the television controller 92 detects x001 control signals on the control connector 90, the television controller 92 controls the video processor 96 to process the video from the video connector 84 and controls the audio processor 98 to process the audio from the audio connector 88.
