The MHL cable has a connector having a shape conforming to the HDMI standard (HDMI terminal) on one end, and a connector having a shape conforming to the USB standard (for example, microUSB) (USB terminal) on the other end.
The MHL is the interface standard which can transmit moving image data (stream) including a video and moving image. In the MHL, an electronic apparatus (source) on the stream output side outputs a stream to an electronic apparatus (sink) on the stream reception side via the MHL cable. The sink can play back the received stream, and can display a played-back video on a display. The source and sink can operate and control partner apparatuses by transmitting commands to the apparatuses connected via the MHL cable.
The video processing apparatus 100 is an electronic apparatus such as a broadcast receiver or recorder which can play back, for example, a broadcast signal or video content stored on a storage medium.

Furthermore, the signal processor 113 can convert (transcode) a bitrate of the stream from an original bitrate to another bitrate. That is, the signal processor 113 can transcode a stream of an original bitrate acquired based on a broadcast signal or the like into that of a lower bitrate. Thus, the signal processor 113 can video-record a content in a capacity-reduced state.
The audio processor 121 converts the digital audio signal received from the signal processor 113 into a signal of a format which can be played back via the loudspeaker 122 (audio signal). For example, the audio processor 121 converts the digital audio signal into an audio signal by digital-to-analog conversion. The audio processor 121 supplies the audio signal to the loudspeaker 122. The loudspeaker 122 outputs sound based on the supplied audio signal.
The video processor 131 converts the digital video signal received from the signal processor 113 into a video signal of a format which can be played back by the display 134. That is, the video processor 131 decodes (plays back) the digital video signal received from the signal processor 113 into a video signal of a format which can be played back by the display 134. The video processor 131 outputs the video signal to the display processor 133.
The display processor 133 applies, for example, image quality adjustment processing of a color, brightness, sharpness, contrast, and the like to the received video signal under the control of the control unit 150.

The transmitter 276 and receiver 176 are connected via an MHL cable. The MHL line includes lines VBUS, GND, CBUS, MHL+, MHL−, and the like.
The VBUS line is used to transmit electric power. For example, the sink supplies electric power of +5 V to the source via the VBUS line. The source can operate using electric power supplied from the sink via the VBUS line. For example, the power source unit of the portable device 200 as the source can charge the battery by electric power supplied from the sink via the VBUS line. The GND line is grounded.
The CBUS line is used to transmit, for example, a control signal such as a command. The CBUS line is used to transmit, for example, a Display Data Channel (DDC) command, MHL Sideband Channel (MSC) command, or the like in two ways. The DDC command is used to read Extended Display Identification Data (EDID), in High-bandwidth Digital Content Protection (HDCP) authentication, and so forth. The EDID is a list of display information, which is set in advance according to the specification of the display or the like. The MSC command is used in read/write control of various registers (not shown), remote controller control, and so forth.
For example, the video processing apparatus 100 as the sink outputs commands to the portable device 200 as the source via the CBUS line. The portable device 200 can execute various kinds of processing according to the received commands.
The source transmits the DDC command to the sink to execute HDCP authentication with the sink, and can read the EDID from the sink.
The HDCP is an encryption method of signals transmitted between the apparatuses. The video processing apparatus 100 and portable device 200 exchange keys and the like in the sequence conforming to HDCP, thus attaining mutual authentication.
Note that the portable device 200 may have an arrangement which acquires EDID from the video processing apparatus 100 not during the HDCP authentication but at another timing.
The portable device 200 analyzes the EDID acquired from the video processing apparatus 100, and recognizes display information indicating a format including a resolution, color depth, transmission frequency, and the like, which can be processed by the video processing apparatus 100. The portable device 200 generates a stream in the format including the resolution, color depth, transmission frequency, and the like, which can be processed by the video processing apparatus 100.
The MHL+ and MHL− lines are used to transmit data. The two MHL+ and MHL− lines function as one twisted-pair line. For example, the MHL+ and MHL− lines function as a Transition Minimized Differential Signaling (TMDS) channel used to transmit data according on the TMDS method. The MHL+ and MHL− lines can transmit a sync signal (MHL clock) according to the TMDS method.
For example, the source can output a stream to the sink via the TMDS channel. That is, the portable device 200, which functions as the source, can transmit a stream obtained by converting video data (display screen) displayed on the display 234 and audio data output from the loudspeaker 222 to the video processing apparatus 100 as the sink. The video processing apparatus 100 receives the transmitted stream via the TMDS channel, and applies signal processing to the received stream, and plays back the processed stream.

The TV control unit 183 issues an output instruction of at least one item of information of the measurement result of the supplied power, charging status prediction, and charging status guide. In response to this instruction, at least one of the video output unit 181 and audio output unit 182 outputs at least one item of information of the measurement result of the supplied power, charging status prediction, and charging status guide.
For example, the video output unit 181 outputs a video of the graphic charging status prediction. Alternatively, the video output unit 181 superimposes a video of the graphic charging status prediction on a content video which is being played back. The content video which is being played back may be that received from the portable device 200 via the connector 178, that on the air which is received via the tuner 111, or that acquired via the storage 160 or LAN interface 171 (network).
The video output unit 181, audio output unit 182, TV control unit 183, and the like output (display) the charging status in various modes. For example, the video output unit 181, audio output unit 182, TV control unit 183, and the like output (display) the charging status by means of a graph. For example, the charging status includes “charging in progress” (
Charging in progress: Power supply to an external apparatus is currently in progress via the connector.
Charging completion: After an external apparatus was connected to the connector, electric power was supplied to the external apparatus via the connector, and the external apparatus is currently connected via the connector, but no electric power is supplied.
Recharging in progress: After an external apparatus was connected to the connector, electric power was supplied to the external apparatus via the connector, and power supply is in progress again via a non-power supply status.
Charging disabled: After an external apparatus was connected to the connector, electric power of a predetermined magnitude or more cannot be supplied even after the elapse of a predetermined time.
Charging interrupted: After an external apparatus was connected to the connector, power supply to the external apparatus was interrupted after monitoring of power supply of a predetermined magnitude or more.
Note that the video output unit 181, audio output unit 182, TV control unit 183, and the like output (display) at least one of the plurality of aforementioned charging statuses. Alternatively, the video output unit 181 alone may output the charging status, the audio output unit 182 alone may output the charging status, and both the video output unit 181 and audio output unit 182 may output the charging status.
Furthermore, the TV control unit 183 may control to predict a charging status in the future using at least one of the stored previous current, electric power, power, and charging status, to calculate a prediction time until charging completion, and to output the calculated prediction time (charging completion prediction time).
As described above, the user can confirm a charging status on a display of an MHL sink (video processing apparatus) irrespective of a use state of an MHL source (portable device) and the viewing content of the MHL sink. That is, the user can recognize the charging status on the MHL sink side by confirming a charging status output on the MHL sink side without turning on the power source of the MHL source. That is, the user can recognize the charging status on the MHL sink side by confirming the charging status output on the MHL sink side without playing back any video on the MHL source.
This embodiment will be summarized below.
(1) The MHL sink (video processing apparatus) according to one embodiment monitors a supplied power to the MHL source (portable device), holds the monitoring result, predicts a charging status of the MHL source based on the monitoring result, and outputs the predicted charging status.
(2) The MHL sink (video processing apparatus) according to one embodiment monitors a change in supplied power to the MHL source according to an elapse of time, holds the monitoring result, predicts a charging status of the MHL source based on the monitoring result, and outputs the predicted charging status. That is, the MHL sink (video processing apparatus) periodically monitors a supplied power to the MHL source (portable device) a plurality of times, holds the monitoring results, predicts the charging status of the MHL source based on the monitoring results, and outputs the predicted charging status.
For example, the MHL sink monitors a supplied power from a supplied current. For example, the MHL sink outputs the monitoring result using, for example, a line graph which plots elapsed time on the abscissa and current on the ordinate. For example, the charging status is any of “charging in progress”, “charging completion”, “recharging in progress”, “charging disabled”, and “charging interrupted”. Alternatively, the charging status is a charging completion prediction time.
The MHL sink can send a predetermined control command (by settings at the time of factory delivery or by the user) to the MHL source based on the charging status via the CBUS line.
The MHL sink can also output the charging status under a predetermined condition (by settings at the time of factory delivery or by the user) based on the charging status.
The MHL sink can also output a predetermined charging status (predetermined one of “charging in progress”, “charging completion”, “recharging in progress”, “charging disabled”, and “charging interrupted”) (by settings at the time of factory delivery or by the user).
Note that this embodiment has explained the case in which the MHL sink includes one connector (MHL sink terminal) 178, supplies electric power to one MHL source via one connector (MHL sink terminal) 178, stores a charging status of one MHL source, and outputs the charging status. However, the present invention is not limited to this. For example, the MHL sink may include a plurality of connectors, may supply electric power to a plurality of MHL sources via the respective connectors, may store charging statuses of the plurality of MHL sources, and may output the charging statuses.
