Problems solved by technology

[0002] Currently, in H.323-based video conferencing products, when H.245 is used for capability negotiation, only traditional video conferencing endpoint capabilities can be negotiated, and telepresence endpoint capabilities cannot be negotiated.
Specifically, when interacting with capabilities, you can only interact with the encoding and decoding capabilities of traditional video conference endpoints, but cannot interact with the newly added media stream receiving and sending capabilities of telepresence endpoints.
When opening a logical channel, only the codec attributes of the logical channel can be specified, and the media stream attributes, codec attributes, multiplexing attributes of the logical channel, and the binding relationship between these telepresence endpoint capability attributes cannot be specified.
[0003] Aiming at the problem that the negotiation method in the related art cannot negotiate the capability set of the telepresence endpoint, no effective solution has been proposed yet

Embodiment 1

[0154] This preferred embodiment provides a method for capability negotiation, which can ensure the negotiation of multi-channel media scene description, codec capability and multiplexing channels between telepresence endpoints.

[0155] In this embodiment, negotiation mode A is provided, Figure 4 It is the flow of the negotiation method of the remote presentation endpoint according to the embodiment of the present invention Figure 1 ,like Figure 4 As shown, the negotiation method includes two parts: capability set interaction and logical channel opening. Including the following steps S401 and S402:

[0156] Step S401: Capability set interaction: two telepresence endpoints perform capability interaction, and carry telepresence endpoint capability sets.

[0157] Step S402: opening a logical channel: opening a logical channel between two telepresence endpoints, specifying the negotiated channel attributes.

[0158] The following will be described in conjunction with examp...

Embodiment 2

[0174] This preferred embodiment provides a method for capability negotiation, which can ensure the negotiation of multi-channel media scene description, codec capability and multiplexing channels between telepresence endpoints.

[0175] This preferred embodiment provides a negotiation mode A-2. In this negotiation mode, the capability set carried in the capability set interaction message is a symmetric capability set, and the symmetric capability set means that the receiving capability set of the endpoint is consistent with the sending capability set. Figure 7 It is the flow of the negotiation method of the remote presentation endpoint according to the embodiment of the present invention Figure four ,like Figure 7 As shown, the method includes step S701 and step S702.

[0176] Step S701: Capability set interaction: Capability set interaction is performed between two telepresence endpoints, and the telepresence endpoint symmetric capability set parameters are carried in th...

Embodiment 3

[0190] This preferred embodiment provides a method for capability negotiation, which can ensure the negotiation of multi-channel media scene description, codec capability and multiplexing channels between telepresence endpoints.

[0191] This preferred embodiment provides a negotiation mode A-3. The capability set carried in the capability set interaction message of the negotiation mode is the sending capability set, and the sending capability set includes parameters related to the sending capability of the endpoint. Figure 9 It is the flow of the negotiation method of the remote presentation endpoint according to the embodiment of the present invention Figure six ,like Figure 9 As shown, the method includes step S901 and step S902.

[0192] Step S901: Capability set interaction: Capability set interaction is performed between two telepresence endpoints, and the telepresence endpoint sends capability set parameters in the message.

[0193] Step S902: opening a logical cha...

Abstract

The invention discloses a method and device of capability interaction of tele-presence endpoints as well as a data stream. The method comprises the following steps that capability interaction is carried out between a first tele-presence endpoint and a second tele-presence endpoint, wherein a tele-presence endpoint capability set is carried in information for capacity interaction, and the tele-presence endpoint capability set comprises a tele-presence endpoint receiving capability set; and the first tele-presence endpoint opens a logical channel between the first tele-presence endpoint and the second tele-presence endpoint according to a result of capability interaction. Through the method and the device of capability interaction of the tele-presence endpoints as well as the data stream, capability interaction of the tele-presence endpoints is implemented and user experience is improved.
