CONTENT-BASED CLIENT SIDE VIDEO TRANSCODING
Among other things, embodiments of the present disclosure improve the functionality of electronic messaging and imaging software and systems by automating the client-side transcoding of video data based on content. For example, an appropriate transcoding configuration can be selected for video data having complex motion or textures. Accordingly, video quality can be improve when complex motions or textures are present.
Method and transition device for enabling communication of data in a wireless network
A method and transition device for enabling communication of data between a remote radio unit and a central baseband unit in a wireless network. When detecting a first interface configuration used by the remote radio unit and a second interface configuration used by the baseband unit, the transition device configures interface functions, based on the first and second interface configurations. The interface functions are selected from a set of predefined interface functions associated with different interface configurations. The transition device then establishes a data flow between the remote radio unit and the central baseband unit over the transition device, and performs conversion between the first interface configuration and the second interface configuration for data communicated in the data flow, using the selected interface functions.
Transmission rate adaptation
A method is provided for transmission rate adaptation of one or more data units, the method including: receiving, by an adapter, the adapter including an adaptation circuitry, a plurality of data units according to a first transmission rate and at least one delay character separating two consecutive data units; and transmitting, by the adapter, each of the plurality of data units received according to a second transmission rate, wherein the second transmission rate is determined based on the at least one delay character received.
Method and system of providing second generation (2G) voice services over Internet protocol
A system to provide second generation (2G) voice services over internet protocol, the system including: a voice gateway (VGW) including a 2G stack to communicate control plane information and user plane information with a 2G user terminal (UT) via a circuit-switched network without modifications to the 2G-UT, an Iu-CS IP stack, and a relay to map the control plane information between the 2G stack and the Iu-CS IP stack, and vice-versa; a mobile switching center (MSC), connected to the VGW via the Iu-CS IP stack, to manage and establish the voice services between the 2G-UT and a public switched telephone network (PSTN) based on the mapped control plane information; and a media gateway (MGW) connected to the VGW via the Iu-CS IP stack, where the MGW communicates the user plane information between the 2G-UT and the PSTN after the MSC 2-G UT vocoder, e.g. AMBE, has established voice services.
Tone Frame Detector for Digital Speech
Tone data embedded in a voice bit stream that includes frames of non-tone bits and frames of tone bits is detected and extracted by selecting a frame of bits, analyzing the selected frame of bits to determine whether it is a frame of tone bits, and, when it is a frame of tone bits, extracting tone data from it. Analyzing the selected frame includes comparing bits of the selected frame to sets of tone data to produce error criteria representative of differences between the selected frame and each of multiple sets of tone data. Based on the error criteria, a set of tone data that most closely corresponds to the bits of the selected frame is selected. When the error criteria corresponding to the selected set of tone data satisfies a set of thresholds, the selected frame is designated as a frame of tone bits.
Content-based client side video transcoding

For example, an appropriate transcoding configuration can be selected for video data having complex motion or textures. Accordingly, video quality can be improve when complex motions or textures are present.
UE and devices for CODEC rate adaptation
Devices, methods, user equipment (UE), network core devices, gateway devices, evolved node B (eNB), and storage media for UE provisioning are described. In one embodiment, a UE is configured for codec bitrate adaptation via an interface configured to receive a bandwidth indication and a codec awareness indication from an eNB. The UE process the bandwidth indication and identifies, based on the codec awareness indication, a first codec from a plurality of codecs supported by the UE. The UE then configures with the eNB using data encoded with the first codec. This data may, for example, be Voice over Long-Term Evolution (VoLTE) data or other such media data. Selection of the codec or associated codec information may be further based on the codec awareness indication.
Communication terminal apparatus and communication method
A communication method supports Enhanced Voice Services (EVS) codec performed by a communication terminal apparatus. The method includes performing negotiation to use an EVS codec for communication between a communication terminal apparatus and a counterpart terminal, using an IP multimedia subsystem (IMS) signaling including one of a session description protocol (SDP) offer and an SDP answer, and performing negotiation to specify one or more audio-bandwidths of input signals in Hertz (Hz) or kilohertz (kHz) for the EVS codec. In a communication session after the codec negotiation session, the processor causes the receiver to receive a signaling for changing an audio-bandwidth of an input signal to the EVS codec from a network node, changes the audio-bandwidth of the input signal to the EVS codec to another audio-bandwidth without changing the EVS codec based on the signaling, and causes the transmitter to transmit encoded data in the changed audio-bandwidth.

Network core facilitating terminal interoperation
An anchoring network device of a telecommunications network can receive a first initiation request of a communication session and determine a second request indicating a different media capability than the first request. A network gateway can modify packets of the session, e.g., by transcoding between the capabilities. In some examples, the anchoring device can determine that a codec list of the initiation request corresponds to a rewrite rule. The device can apply the rewrite rule to the request to provide a second request listing a second, different codec. In some examples, the anchoring device can determine if there is a common media capability between the first initiation request and a predetermined exclusion list. If not, the second request can include at least one capability not in the first request, e.g., an Enhanced Voice Services (EVS) Channel-Aware-mode (ChAw) codec.
