Abstract
Abstract A transmission system is a data delivery system which includes a server for transmitting ES data and a receiving terminal for receiving the transmitted data. The server includes a conversion controller for determining elementary streams (ES's) and a scene description to be transmitted based on transmission priority levels and display priority levels, in accordance with the state of a transmission path and/or a request from the receiving terminal. The server also includes an ES processor and a scene description processor.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
99 words
A transmission apparatus for transmitting to a receiving apparatus at least two different signals and a scene description which describes a scene formed of said at least two different signals, comprising: maintaining means for maintaining priority level information indicating transmission priority levels with respect to said at least two different signals; determining means for determining, in accordance with the state of a transmission path and/or a request from said receiving apparatus, signals to be transmitted based on the priority level information; and scene description converting means for converting the scene description in accordance with the signals to be transmitted.
Claim 2
Dependent Claim
99 words
A transmission apparatus for transmitting to a receiving apparatus at least two different signals and a scene description which describes a scene formed of said at least two different signals, comprising: maintaining means for maintaining priority level information indicating transmission priority levels with respect to said at least two different signals; determining means for determining, in accordance with the state of a transmission path and/or a request from said receiving apparatus, signals to be transmitted based on the priority level information; and scene description converting means for converting the scene description in accordance with the signals to be transmitted.
Claim 3
Dependent Claim
25 words
A transmission apparatus according to claim 1 , wherein said determining means determines the signals to be transmitted in descending order of the priority levels.
Claim 4
Dependent Claim
46 words
A transmission apparatus according to claim 1 , wherein said scene description converting means converts the scene description so that a larger display region and/or a more highly preferential display position is assigned to the signals to be transmitted in descending order of the priority levels.
Claim 5
Dependent Claim
35 words
A transmission apparatus according to claim 1 , further comprising priority level determining means for determining the priority level of each of said at least two different signals in accordance with the type of signal.
Claim 6
Dependent Claim
32 words
A transmission apparatus according to claim 1 , wherein said determining means determines only the signal that complies with the processing capacity of said receiving apparatus based on the priority level information.
Claim 7
Dependent Claim
28 words
A transmission apparatus according to claim 1 , wherein said maintaining means also maintains information indicating display priority levels with respect to said at least two different signals.
Claim 8
Dependent Claim
105 words
A transmission method for transmitting to a receiving apparatus at least two different signals and a scene description which describes a scene formed of said at least two different signals, comprising: a maintaining step of maintaining, in a memory, priority level information indicating transmission priority levels with respect to said at least two different signals; a determining step of determining, in accordance with the state of a transmission path and/or a request from said receiving apparatus, signals to be transmitted based on the priority level information; and a scene description converting step of converting the scene description in accordance with the signals to be transmitted.
Claim 9
Dependent Claim
105 words
A transmission method for transmitting to a receiving apparatus at least two different signals and a scene description which describes a scene formed of said at least two different signals, comprising: a maintaining step of maintaining, in a memory, priority level information indicating transmission priority levels with respect to said at least two different signals; a determining step of determining, in accordance with the state of a transmission path and/or a request from said receiving apparatus, signals to be transmitted based on the priority level information; and a scene description converting step of converting the scene description in accordance with the signals to be transmitted.
Claim 10
Dependent Claim
27 words
A transmission method according to claim 7 , wherein, in said determining step, the signals to be transmitted are determined in descending order of the priority levels.
Claim 11
Dependent Claim
48 words
A transmission method according to claim 7 , wherein, in said scene description converting step, the scene description is converted so that a larger display region and/or a more highly preferential display position is assigned to the signals to be transmitted in descending order of the priority levels.
Claim 12
Dependent Claim
36 words
A transmission method according to claim 7 , further comprising a priority level determining step of determining the priority level of each of said at least two different signals in accordance with the type of signal.
Claim 13
Dependent Claim
34 words
A transmission method according to claim 7 , wherein, in said determining step, only the signal that complies with the processing capacity of said receiving apparatus is determined based on the priority level information.
Claim 14
Dependent Claim
27 words
A transmission method according to claim 7 , wherein the memory also maintains information indicating display priority levels with respect to said at least two different signals.
Claim 15
Dependent Claim
136 words
A transmission system comprising: a transmission apparatus for transmitting at least two different signals and a scene description which describes a scene formed of said at least two different signals; and a receiving apparatus for receiving the transmitted signals and the scene description; wherein said transmission apparatus comprises: maintaining means for maintaining priority level information indicating transmission priority levels with respect to said at least two different signals; determining means for determining, in accordance with the state of a transmission path or a request from said receiving apparatus, signals to be transmitted based on the priority level information; and scene description converting means for converting the scene description in accordance with the signals to be transmitted; and said receiving apparatus comprises: forming means for forming a scene based on the received signals and the scene description.
Claim 16
Dependent Claim
136 words
A transmission system comprising: a transmission apparatus for transmitting at least two different signals and a scene description which describes a scene formed of said at least two different signals; and a receiving apparatus for receiving the transmitted signals and the scene description; wherein said transmission apparatus comprises: maintaining means for maintaining priority level information indicating transmission priority levels with respect to said at least two different signals; determining means for determining, in accordance with the state of a transmission path or a request from said receiving apparatus, signals to be transmitted based on the priority level information; and scene description converting means for converting the scene description in accordance with the signals to be transmitted; and said receiving apparatus comprises: forming means for forming a scene based on the received signals and the scene description.
