Digital Transport Adapter

A method comprising:

• receiving, by a computing device, a multi-program data stream comprising a plurality of programs;
• responsive to receiving, from a client device, a request for a new program, replacing a first association table from the multi-program data stream with a second association table comprising information indicative of assets associated with the new program;
• transmitting, by the computing device and to the client device, a single-program data stream comprising the second association table and the assets associated with the new program;
• determining a period of time for which the client device is to use the second association table;
• and
• responsive to determining that the period of time has elapsed, replacing the second association table with the first association table in the single-program data stream.

An apparatus comprising:

• one or more processors;
• and
• memory storing computer executable instructions that, when executed by the one or more processors, cause the apparatus to:
• receive a multi-program data stream comprising a plurality of programs;
• responsive to receiving, from a client device, a request for a new program, replace a first association table from the multi-program data stream with a second association table comprising information indicative of assets associated with the new program;
• transmit, to the client device, a single-program data stream comprising the second association table and the assets associated with the new program;
• determine a period of time for which the client device is to use the second association table;
• and
• responsive to determining that the period of time has elapsed, replace the second association table with the first association table in the single-program data stream.

One or more computer readable storage media comprising computer executable instructions that, when executed by a computing device, cause the computing device to:

• receive a multi-program data stream comprising a plurality of programs;
• responsive to receiving, from a client device, a request for a new program, replace a first association table from the multi-program data stream with a second association table comprising information indicative of assets associated with the new program;
• transmit, to the client device, a single-program data stream comprising the second association table and the assets associated with the new program;
• determine a period of time for which the client device is to use the second association table;
• and
• responsive to determining that the period of time has elapsed, replace the second association table with the first association table in the single-program data stream.
