Abstract

Claims (33)

1. A method of performing video coding in a network-based system, performed by an encoding device, the method comprising:

obtaining a video content;

determining an encoding parameter set for encoding the video content and a decoding parameter set for decoding the video content among multiple parameter sets,

wherein the multiple parameter sets for encoding the video content and decoding the video content are generated using a trained parameter set model,

wherein the encoding parameter set for encoding the video content is selected specifically for an encoding instance and is based on a training data of a content type of the video content,

wherein the decoding parameter set for decoding the video content is selected specifically for a decoding instance and is based on the training data of the content type of the video content, and

wherein the content type of the video content includes a plurality of game types comprising at least one of a game genre and a game title;

encoding the video content according to the encoding parameter set;

transmitting the encoded video content to a decoding device;

transmitting an indicator flag indicating to a decoder that the decoding parameter set is to be used for decoding the video content instead of a default parameter set; and

transmitting the encoding parameter set to the decoding device, wherein the transmitting of the encoding parameter set is distinct from the transmitting of the encoded video content.

2. The method of claim 1 , wherein a parameter set comprises a set of filter coefficients to perform filtering on one or more images of the video content.

3. The method of claim 1 , wherein at least one parameter set is determined for each of the plurality of game types.

4. The method of claim 1 , wherein the default parameter set is transmitted to the decoding device prior to the encoded video content, or wherein more than one default parameter set is transmitted to the decoding device prior to the encoded video content.

5. The method of claim 1 , wherein the determined parameter set is transmitted to the decoding device as metadata.

6. A non-transitory computer-readable storage medium storing computer program code, the computer program code, when executed by at least one processor is configured to perform a method of claim 1 .

7. An encoding device comprising:

at least one memory storing a computer program code; and

at least one processor configured to access the at least one memory and operate as instructed by the computer program code, the computer program code comprising:

obtaining code configured to cause the at least one processor to obtain a video content;

determining code configured to cause the at least one processor to determine an encoding parameter set for encoding the video content and a decoding parameter set for decoding the video content among multiple parameter sets,

wherein the multiple parameter sets for encoding the video content and decoding the video content are generated using a trained parameter set model,

wherein the encoding parameter set for encoding the video content is selected specifically for an encoding instance and is based on a training data of a content type of the video content,

wherein the decoding parameter set for decoding the video content is selected specifically for a decoding instance and is based on the training data of the content type of the video content, and

wherein the content type of the video content includes a plurality of game types comprising at least one of a game genre and a game title;

encoding code configured to cause the at least one processor to encode the video content according to the encoding parameter set;

first transmitting code configured to cause the at least one processor to control a communication interface to transmit the encoded video content to a decoding device;

second transmitting code configured to cause the at least one processor to control the communication interface to transmit an indicator flag indicating to a decoder that the parameter set is to be used for decoding the video content instead of a default parameter set; and

third transmitting code configured to cause the at least one processor to control the communication interface to transmit the encoding parameter set to the decoding device, wherein the transmitting of the encoding parameter set is distinct from the transmitting of the encoded video content.

8. The encoding device of claim 7 , wherein a parameter set comprises a set of filter coefficients to perform filtering on one or more images of the video content.

9. The encoding device of claim 7 , wherein at least one parameter is determined for each of the plurality of game types.

10. The encoding device of claim 7 , wherein the determined parameter set is transmitted to the decoding device as metadata.

11. The encoding device of claim 7 , wherein the default parameter set is transmitted to the decoding device prior to the encoded video content, or wherein more than one default parameter sets is transmitted to the decoding device prior to the encoded video content.
