1. A method for minimizing bandwidth usage between a media device and a communication server in a communication system, the method comprising:
at the communication server:
receiving, from a first client, a request for a first session and a first floor request for a media source at the media device;
receiving, from a second client, a request for a second session and a second floor request for the media source;
granting the requests for the first and second sessions, wherein the first session is separate from the second session;
determining that the first and second floor requests are for the same media source;
receiving media from the media source using a single media stream established using floor control signaling;
in response to the first floor request, delivering the media to the first client during the first session; and
in response to the second floor request, delivering the media to the second client during the second session.
2. The method of claim 1, wherein a single message from the first client includes both the request for the first session and the first floor request.
3. The method of claim 1, wherein a single message from the second client includes both the request for the second session and the second floor request.
4. The method of claim 1, wherein the communication server logically links the separate first and second sessions to a shared session with the media device.
5. The method of claim 4, wherein the separate first and second sessions are logically linked by being assigned the same session identifier.
6. The method of claim 4 further comprising, the communication server:
receiving a request, from the first client, to terminate the first session;
receiving a request, from the second client, to terminate the second session; and
upon determining that no other clients have an active session that is logically linked to the shared session with the media device, terminating the shared session.
7. The method of claim 1 further comprising the communication server determining bandwidth allocation for the media source and at least one other media source that share a common uplink, wherein the bandwidth allocation is determined based at least on: a maximum bandwidth requirement for any of the media sources that share the common uplink; and the number of media sources that share the common uplink.
8. The method of claim 1 further comprising, the communication server:
receiving, from the first client, a floor release request for the media source;
determining whether any other clients are receiving the media from the media source; and
when no other clients are receiving the media from the media source, sending the floor release request to the media device.
9. The method of claim 8, wherein the floor release request comprises a floor request for a second media source at the media device.
10. The method of claim 8, wherein the floor release request comprises a request to terminate the first session.
11. The method of claim 1, wherein using floor control signaling to establish the single media stream comprises, the communication server:
sending a floor grant to the media device for the media source in response to the first floor request;
determining to withhold sending another grant to the media source in response to the second floor request as a result of determining that the first and second floor requests are for the same media source.
12. The method of claim 1 further comprising, the communication server:
determining that the media device includes multiple media sources; and
sending parameters to the media device for establishing a separate media stream for each media source at the media device.
13. The method of claim 12 further comprising, the communication server:
receiving a third floor request, from the first client, for a second different media source at the media device;
receiving media from the second media source using a single second media stream established using floor control signaling and established using the parameters sent to the media device; and
sending the media from the second media source to the first client in response to the third floor request.
14. The method of claim 13 further comprising, the communication server:
receiving a fourth floor request, from the second client, for the second media source; and
in response to the fourth floor request, sending to the second client the media that the communication server received using the second media stream.
15. A communication server for minimizing bandwidth usage between a media device and the communication server in a communication system, the communication server comprising:
a call controller that:
receives, from a first client, a request for a first session and a first floor request for a media source at the media device and establishes a first floor arbiter;
receives, from a second client, a request for a second session and a second floor request for the media source, and establishes a second floor arbiter;
grants the requests for the first and second sessions, wherein the first session is separate from the second session; and
determines that the first and second floor requests are for the same media source and generates a shared media source arbiter that interfaces between the media device and the first and second floor arbiters;
the first floor arbiter that exchanges floor control signaling with the first client to respond to the first floor request;
the second floor arbiter that exchanges floor control signaling with the second client to respond to the second floor request;
the shared arbiter that exchanges floor control signaling with the media device to cause media to be sent from the media source to the communication server using a single media stream; and
a media manager that delivers the media to the first client during the first session and delivers the media to the second client during the second session.
16. The communication server of claim 15 further comprising a bandwidth manager that determines bandwidth allocation for the media source and at least one other media source that share a common uplink, wherein the bandwidth allocation is determined based at least on: a maximum bandwidth requirement for any of the media sources that share the common uplink; and the number of media sources that share the common uplink.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A method of manufacturing a fixture of a dental implant, the method comprising:
cutting the fixture of the dental implant to form a male screw portion of the fixture;
forming a fixed groove in the male screw portion of the fixture to surround a portion of the male screw portion in a circumferential direction of the male screw portion, wherein a protection jig comprising a body portion having a combination hole inserted and fixed in the male screw portion of the fixture; and at least one fixed protrusion formed in an internal side of the combination hole so as to be inserted in the fixed groove of the fixture and fixed therein;
performing jig fixing in such a way that the protection jig is inserted in a ring-shaped male screw portion to surround a portion of the male screw portion of the fixture in a circumferential direction of the protection jig;
performing surface processing on the male screw portion of the fixture to increase a surface roughness; and
performing jig removal in such a way that the protection jig fixed on the male screw portion is removed from the male screw portion of the fixture.
2. The method of claim 1, wherein the protection jig is formed of polymer having elasticity.
3. The method of claim 1, wherein a female screw portion is formed at an inner diameter of the protection jig to be engaged with the male screw portion.
4. The method of claim 1, wherein the performing of surface processing is performed using sandblasting.
5. The method of claim 1, wherein the performing of surface processing is performed using anodization.
6. The method of claim 1, wherein the fixed protrusion of the protection jig is ring-shaped.
