7. A method comprising:
transmitting, from an apparatus, a query to a content server;
receiving, by the apparatus, a count value from the content server;
reproducing, by the apparatus, content in synchronization with the content server based at least in part on a sampling frequency of the content server; and
performing, by the apparatus, at least one synchronization correction for the reproduced content based at least in part on:
the received count value;
a round trip time between the transmission of the query and the reception of the count value; and
a difference between the sampling frequency of the content server and a sampling frequency of the apparatus that occurred at a previous correction time.
8. The method of claim 7, further comprising increasing or decreasing a number of samples of the reproduced content.
9. The method of claim 8, further comprising increasing the number of the samples by interpolating between samples preceding and following a target sample.
10. The method of claim 7, further comprising synchronizing the sampling frequency of the apparatus according to a sampling clock of the content reproduced by the content server.
11. The method of claim 7, wherein the content is transmitted from the content server to the apparatus.
12. At least one computer readable medium comprising instructions that, when executed by at least one processor, cause the at least one processor to perform a method comprising:
transmitting, from an apparatus, a query to a content server;
receiving, by the apparatus, a count value from the content server;
reproducing, by the apparatus, content in synchronization with the content server based at least in part on a sampling frequency of the content server; and
performing, by the apparatus, at least one synchronization correction for the reproduced content based at least in part on:
the received count value;
a round trip time between the transmission of the query and the reception of the count value; and
a difference between the sampling frequency of the content server and a sampling frequency of the apparatus that occurred at a previous correction time.
13. The at least one computer readable medium of claim 12, wherein the method further comprises increasing or decreasing a number of samples of the reproduced content.
14. The at least one computer readable medium of claim 13, wherein the method further comprises increasing the number of the samples by interpolating between samples preceding and following a target sample.
15. The at least one computer readable medium of claim 12, wherein the method further comprises synchronizing the sampling frequency of the apparatus according to a sampling clock of the content reproduced by the content server.
16. The at least one computer readable medium of claim 12, wherein the content is transmitted from the content server to the apparatus.
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. Light emitting module comprising:
a light source;
a heat sink, the light source being applied on the heat sink and being thermally connected to the heat sink, the heat sink being configured for being detachably mounted on a cooling body, wherein at least part of an outer wall of the heat sink comprises a shape matching at least a part of an outer wall of the cooling body for transferring heat generated by the light source to the cooling body, and wherein said outer wall of the heat sink is configured to partially envelop the outer wall of the cooling body; and
mounting means for detachably mounting the heat sink on the cooling body, wherein said mounting means is an elastic mounting means that is composed of a material that is different from a material composing the at least a part of the outer wall of the heat sink and wherein said mounting means and said heat sink are configured such that said mounting means remains attached to said heat sink when said heat sink is detached from said cooling body.
2. Light emitting module as claimed in claim 1, wherein the outer wall of the heat sink is curved inward into the heat sink, the curved outer wall being defined by a radius substantially matching a radius of the cooling body.
3. Light emitting module as claimed in claim 2, wherein the outer wall of the heat sink has as substantially cylindrical shape.
4. Light emitting module as claimed in claim 1, wherein the outer wall of the heat sink comprises a first curved wall portion being defined by a first radius (R1) and a second curved wall portion being defined by a second radius (R2) being larger than the first radius (R1).
5. Light emitting module as claimed in claim 4, wherein the first curved wall portion is integrated within the second curved wall portion.
6. Light emitting module as claimed in claim 1, wherein the heat sink comprises an electrically conductive path between the cooling body and the light source.
