Abstract
The invention discloses a method for controlling a remote camera in a multi-frame session and a multipoint control unit. The method comprises three states defined for an MCU, namely an idle state, a selection state and a control state, wherein in the idle state, the MCU receives an arbitrary FECC signaling transmitted from a controller, enters the selection state and selects a default frame; in the selection state, the MCU receives an FECC selection signaling transmitted by the controller, and switches the selected frame; in the select state, the MCU receives an FECC Home signaling transmitted by the controller, enters the control state and selects the currently-selected frame; and in the control state, the MCU receives an FECC control signaling transmitted from the controller and transmits the FECC control signaling to a controlled person corresponding to the selected frame, and the controlled person controls a local camera according to the FECC control signaling. The method and the multipoint control unit realize accurate control on the camera of a sub-frame in the multi-frame session.
Description
Technical field
The present invention relates to the multi-frame session technical field, be specifically related to method for controlling remote camera and multipoint control unit (MCU, Multipoint Control Unit) in the multi-frame session.
Background technology
During video product is used,, relate to control, comprise and control local terminal camera and far-end camera camera through regular meeting owing to reasons such as camera is put, camera lens sensings, focusings.When control far-end camera, the effector is with remote camera control (FECC, Far End Camera Control) signaling bear is at real time transport protocol (RTP, Real-time Transport Protocol) in the passage, after Be Controlled person receives the RTP data, resolve FECC signaling wherein, convert control command to local camera.
At present, in point to point call and single-image meeting, can both realize preferably the picture of watching is carried out camera control.But in multi-frame session, the effector can be in the face of the picture more than of a plurality of meeting-place composition, and camera how accurately to control each sprite has just become the key issue that will solve.
A kind of scheme is: the keeper is selected effector and Be Controlled person on the WEB of the MCU page, and the selected effector control command that will send, and then effector's FECC signaling is sent to Be Controlled person.The shortcoming of this scheme is, need to cooperate the WEB page to select, very inconvenient, and owing to only show each sprite usually on the WEB browser, and do not mark the position, meeting-place of each sprite correspondence, therefore, when the keeper selects effector, Be Controlled person on the WEB page, also than being easier to select mistake.
Another kind of scheme is: the effector always controls a fixed image in the picture, generally be the picture in the upper left corner, or the picture of No. 0 position promptly: most important picture.The shortcoming of this scheme is that the effector has been subjected to considerable restraint to the camera control of many pictures, can't select other picture in many pictures.

MCU can superpose one on selected picture and be in the frame or the icon of selection mode.
Step 102: under the selection mode, MCU receive FECC that the effector sends select signaling as: on move (Up) or move down (Down) or (Right) signaling that moves to left (Left) or move to right, according to this signaling, change selected sprite.
Step 103: under the selection mode, MCU receives the FECC Home signaling that the effector sends, and enters state of a control, and chooses current selected picture.
MCU can superpose one on choosing picture and be in the frame or the icon of state of a control.In this step, MCU will cancel the frame that is in selection mode or the icon that superpose earlier on this picture before one of stack is in the frame or icon of state of a control on the choosing picture.
Under the selection mode, MCU receives other FECC signaling except that Up/Down/Left/Right/Home that the effector sends, and does not carry out any operation, does not change the present located state that is:, does not also change current selected picture.
Step 104: under the state of a control, MCU receive FECC control signaling that the effector sends as: recover default setting (Home) or Up or Down or Left or Right or amplification (Zoom Out) or dwindle (Zoom In) or Focus (focusing), this FECC control signaling is sent to the current Be Controlled person who chooses the picture correspondence, and Be Controlled person controls local camera according to this FECC control signaling.
Need to prove, the Up/Down/Left/Right signaling in this step at be operation to camera, and the Up/Down/Left/Right signaling in the step 102 at be operation to picture.
Step 105: under the selection mode, MCU does not receive any FECC signaling that the effector sends in the first default duration, enter idle condition.
Step 106: under the state of a control, MCU does not receive any FECC signaling that the effector sends in the second default duration, enter idle condition.
