Abstract

An apparatus including a tuner configured for receiving television signals; a CPU configured to cause the apparatus to perform operations including receiving configuration data from a first server; receiving a broadcast data stream for the television content via the tuner; obtaining a first plurality of data chunks from the broadcast data stream, wherein each data chunk encodes a portion of audio and/or video included in the broadcast data stream; determining, based on the configuration data, which of the first plurality of data chunks are included in a second plurality of data chunks for uploading, wherein at least one of the first plurality of data chunks is not included in the second plurality of data chunks; and uploading the second plurality of data chunks to a second server.

Claims14

Dependent claims

A method comprising:

receiving configuration data from a server, wherein the configuration data comprises a first value or a first range of values;
receiving a suggestion from the server for recording television signals pertaining to one or more particular television content;
upon or while receiving the configuration data, receiving a broadcast data stream which includes data for the one or more particular television content;
obtaining a first plurality of data chunks from the broadcast data stream, wherein each data chunk encodes a portion of audio and/or video included in the broadcast data stream;
calculating a value for each of the first plurality of data chunks;
determining, based on the respective calculated values for the plurality of data chunks and the first value or first range of values in the configuration data, which of the first plurality of data chunks are included in a second plurality of data chunks for uploading, wherein at least one of the first plurality of data chunks is not included in the second plurality of data chunks;
and
uploading the second plurality of data chunks;
wherein calculating the respective values for the first plurality of data chunks comprises
generating a respective hash value for each of the first plurality of data chunks, and
applying a modulus operation to each of the respective hash values and obtaining, as a result, a remainder for each of the first plurality of data chunks;
and
wherein determining which of the first plurality of data chunks are included in a second plurality of data chunks comprises:
determining, for each remainder, that the data chunk associated with the remainder is included in the second plurality of data chunks in response to the remainder being in the value or in the range of values, and is not included in the second plurality of data chunks in response to the remainder not being included in the value or the range of values.

11 more elements

A method comprising:

receiving a suggestion for recording a particular television content;
identifying a first tuner-device and a second tuner-device as participating in an upload of a plurality of data chunks obtained from a broadcast data stream for the particular television content;
determining respective upload speeds of the first tuner-device and of the second tuner-device;
generating, based on the respective upload speeds of the first tuner-device and of the second tuner-device, a first value or a first range of values for the first tuner-device and a second value or a second range of values for the second tuner-device;
sending, via a network, the first value or the first range of values to the first tuner-device and the second value or the second range of values to the second tuner-device, the first value or the first range of values to be used by an algorithmic filter of the first tuner-device to determine which of a plurality of data chunks the first tuner-device is to upload, and the second value or the second range of values to be used by an algorithmic filter of the second tuner-device to determine which of the plurality of data chunks the second tuner-device is to upload;
and
receiving, from the first tuner-device via the network, a first plurality of data chunks among the plurality of data chunks, and receiving, from the second tuner-device via the network, a second plurality of data chunks among the plurality of data chunks.

4 more elements

A system comprising:

a server comprising a processor configured to cause the server to perform operations comprising:
generating a suggestion for recording a particular television content;
identifying a first tuner-device and a second tuner-device as participating in an upload of a plurality of data chunks obtained from a broadcast data stream for the particular television content;
determining respective upload speeds of the first tuner-device and of the second tuner-device;
generating, based on the respective upload speeds of the first tuner-device and of the second tuner-device, a first value or a first range of values for the first tuner-device and a second value or a second range of values for the second tuner-device;
sending, via a network, the first value or the first range of values to the first tuner-device and the second value or the second range of values to the second tuner-device, the first value or the first range of values to be used by an algorithmic filter of the first tuner-device to determine which of a plurality of data chunks the first tuner-device is to upload, and the second value or the second range of values to be used by an algorithmic filter of the second tuner-device to determine which of the plurality of data chunks the second tuner-device is to upload;
and
receiving, from the first tuner-device via the network, a first plurality of data chunks among the plurality of data chunks, and receiving, from the second tuner-device via the network, a second plurality of data chunks among the plurality of data chunks.
