• the generation of a 3GP file from the ISO BMFF track that conforms to the 26143_CONTAINER_MP4_3GP9 or 26143_CONTAINER_MP4 capability as defined in clause 5.2.
• the provisioning of media type signalling with the generated file using video/mp4, profile="3gp9" codecs="hvc1.2.4.L123.B0" or video/mp4, codecs="hvc1.2.4.L123.B0", or an equivalently compatible media type.

The capability 26143_VIDEO_ENC_HEVC-UHD for a content generator is defined as the combination of the following capabilities:

• the capability to generate a file from a video signal in real-time, such that the file can be played back by a player with the capability 26143_VIDEO_HEVC-UHD,
• the HEVC-UHD-Enc encoding capabilities as defined in clause 5.4 of TS 26.265 to generate a bitstream from the video signal
• the capability to generate an ISO BMFF track from the bitstream that conforms with the requirements of the sample entry 'hvc1' as defined in ISO/IEC 14496-15 [15].
• the generation of a 3GP file from the ISO BMFF track that conforms to the 26143_CONTAINER_MP4_3GP9 or 26143_CONTAINER_MP4 capability as defined in clause 5.2.
• the provisioning of media type signalling with the generated file using video/mp4, profile="3gp9" codecs="hvc1.2.4.L153.B0" or video/mp4, codecs="hvc1.2.4.L153.B0", or an equivalently compatible media type.

The capability 26143_TT_3GPP is defined as the capability of decoding and rendering a file that

• includes a track conforming conforms to the sample entry 'tx3g' as defined in TS 26.245 and
• is contained in a 3GP file that conforms to the 26143_CONTAINER_MP4_3GP9 capability as defined in clause 5.2.

In the context of this specification, the media type for files with this capability 26143_TT_3GPP shall be signalled with text/mp4, profile="3gp9" codecs="tx3g" or an equivalently compatible media type. The capability 26143_TT_IMSC11 is defined as the capability of decoding and rendering a file that

• includes a track conforming conforms to the sample entry 'stpp' as defined in ISO/IEC 14496-30 [28] and
• is contained in a 3GP file that conforms to the 26143_CONTAINER_MP4_3GP9 capability as defined in clause 5.2.

In the context of this specification, the media type for files with this capability 26143_TT_IMSC11 shall be signalled with application/mp4, profile="3gp9" codecs="stpp.ttml.im2t" or an equivalently compatible media type.

The capability 26143_ENC_TT_3GPP for a content generator is defined as the combination of the following capabilities:

• the capability to generate a file from a timed text signal, such that the file can be played back by a player with the capability 26143_TT_3GPP,
• the capability to generate an ISO BMFF track from the bitstream track that conforms with the requirements of the sample entry 'tx3g' as defined in TS 26.245.
• the generation of a 3GP file from the ISO BMFF track that conforms to the 26143_CONTAINER_MP4_3GP9 capability as defined in clause 5.2.
• the provisioning of media type signalling with the generated file using video/mp4, profile="3gp9" codecs="tx3g" or an equivalently compatible media type.
