Information processor and information processing method

An information processing method, comprising:

• in an information processor that includes a communication circuit, a decoder, and a memory:
• receiving, by the communication circuit, encoded image data;
• decoding, by the decoder, the encoded image data received by the communication circuit;
• associating, by the decoder, a first time with each of a plurality of decoded image frames of the decoded image data;
• outputting, by the decoder, decoded image data based on the decoding of the encoded image data;
• storing, in the memory, the plurality of decoded image frames of the decoded image data output by the decoder, a preceding stored image of the plurality of decoded image frames as a preceding queue of a plurality of queues, a succeeding stored image of the plurality of decoded image frames as a succeeding queue of the plurality of queues, and metadata,
• wherein
• the metadata includes the first time at which each of the plurality of decoded image frames is input to the memory, and transmission frame rate information of the each of the plurality of decoded image frames, and
• each of the plurality of decoded image frames is input to the memory at the first time after the decoding of the encoded image data;
• determining an elapsed time from the first time as a waiting time based on the stored metadata;
• comparing the waiting time and a buffering time in each of the plurality of queues based on the preceding stored image and the succeeding stored image, wherein the buffering time is a time required to store data in the memory;
• selecting one of the plurality of decoded image frames as an output image for display, wherein the selected one of the plurality of decoded image frames corresponds to a newest queue among the plurality of queues in which the waiting time exceeds the buffering time;
• and
• controlling a display unit to display the output image based on the transmission frame rate information.

A non-transitory computer-readable medium having stored thereon, computer-executable instructions that when executed by a processor in a computer, cause the computer to execute operations, the operations comprising:

• receiving, by a communication circuit, encoded image data;
• decoding, by a decoder, the encoded image data received by the communication circuit;
• associating, by the decoder, a first time with each of a plurality of decoded image frames of the decoded image data;
• outputting, by the decoder, decoded image data based on the decoding of the encoded image data;
• storing, in a memory, the plurality of decoded image frames of the decoded image data output by the decoder, a preceding stored image of the plurality of decoded image frames as a preceding queue of a plurality of queues, a succeeding stored image of the plurality of decoded image frames as a succeeding queue of the plurality of queues, and metadata,
• wherein
• the metadata includes the first time at which each of the plurality of decoded image frames is input to the memory, and transmission frame rate information of each of the plurality of decoded image frames, and
• each of the plurality of decoded image frames is input to the memory at the first time after the decoding of the encoded image data;
• determining an elapsed time from the first time as a waiting time based on the stored metadata;
• comparing the waiting time and a buffering time in each of the plurality of queues based on the preceding stored image and the succeeding stored image, wherein the buffering time is a time required to store data in the memory;
• selecting one of the plurality of decoded image frames as an output image for display, wherein the selected one of the plurality of decoded image frames corresponds to a newest queue among the plurality of queues in which the waiting time exceeds the buffering time;
• and
• controlling a display unit to display the output image based on the transmission frame rate information.
